Dog to Dog Aggression –
Why and How to Stop It

When dealing with dog-to-dog aggression, it is important to listen to our dog.

There are many reasons why a dog may act aggressively toward another.

  • He may be afraid.
  • He may be stressed because his space is being violated.
  • He may feel the need to dominate.
  • He may be protective of us.
  • He may be very curious.
  • He may just be over-excited.

Sometimes, what we perceive to be aggression may be the result of hyper energy, eagerness, or natural inquisitiveness. Therefore, in dog-to-dog aggression cases, it is important to understand what our dog is feeling, and what he is trying to say.

When my dog meets a new dog, I observe both of them carefully. As soon as my dog starts to get stressed, I step in and interrupt before the situation escalates.

For dog aggression issues, it is best to take a dog’s age, health, temperament, and preferences into account, while coming up with appropriate solutions.

Dog-to-Dog Aggression Tip 1

Be calm and decisive.

Dogs are very sensitive to what their human is feeling. My dog picks up on my emotions and reflects them, except with much more intensity. Sometimes, I am not even conscious of feeling nervous or stressed, but my dog notices it and starts to act up. Once I consciously calm myself down, his behavior also improves.

A common mistake when meeting other dogs is to tense up, and get fearful of what our dog may do. If we are afraid, our dog will pick up on that fearful energy, and that will likely trigger an aggressive reaction.

Be careful not to put undue or continuous tension on the leash. Also, do not pull the dog straight back, as that will likely cause a lunge forward response. To remove my dog, I pull him to the side and quickly walk him past the other dog.

Dog-to-Dog Aggression Tip 2


Ignore, Ignore, Ignore – Teach our dog avoidance.

When I see another dog, I usually just ignore him and move along.

I have found that avoidance is most effective when I avert my eyes from both dog, as well as owner. I keep my eyes forward, and keep walking at a natural pace. In this way, my dog learns that when we see other dogs, we avoid rather than confront.

Be careful not to crowd our dog while walking. If he feels trapped between us and the other dog, he may think he has no choice but to react aggressively. Do not stand still while trying to tug our dog away. Move away, and he will come along with us. At the same time, we are creating space so that he will not feel trapped.

I do not let my dog obsess or stare intensely at other dogs. Sometimes, my Shiba Inu will drop into a stalking-down-position, stare, and wait for the other dog to pass. Some people think that he is such a good boy for doing a Down, when other dogs are coming toward him, but he is actually just waiting to pounce.

Do not allow this bad behavior, do not let our dog practice it, do not even let him think about it. Just move him along, and ignore. If the other dog is somehow blocking us (e.g. if the owner is unable to control his dog), then walk away in a different direction. Do not stare the other dog down and do not confront him, either through posture or by physically engaging him.

Challenging unknown dogs is a good way to get bitten.

Dog-to-Dog Aggression Tip 3


Create space or block the other dog.

We can do this by moving across the road or into a driveway, and waiting for the other dog to pass.

We may also move our dog behind a barrier, for example a car. If there are no barriers available, we can try blocking the dog’s view with our body.

By doing this, we avoid a head-on, more confrontational passing.

I have tried all of these blocking techniques, but what works best for me is to create space, and quickly move past the other dog. Whenever I wait for the other dog to pass, my Shiba uses that time to start obsessing.

Dog treats and trying to get his attention do not work at this point, because the other dog is too close, and Shiba Sephy is no longer listening. The advantage of walking Sephy briskly past the other dog, is that he has less time to stare. In addition, he cannot fully obsess, because he must partly focus on walking.

However, using barriers and blocking may work better for a fearful dog.

Some trainers suggest turning and walking away when we see another dog, rather than passing him or waiting for him to pass.

There are two problems with this method:

  • If we turn away, the other dog will be following us. This may cause some dogs to keep looking back, to make sure that the follower is not a threat. I have tried this, and indeed my Shiba keeps looking back.
  • If we keep turning away, we may meet other dogs and get boxed in; especially if there are many dogs in our neighborhood.

Dog-to-Dog Aggression Tip 4

Create neutral experiences.

I try to create as many neutral dog-to-dog meeting experiences as possible. If every time my dog sees another dog, we just pass by and nothing interesting happens, it will become a non-event.

Being consistent with neutral greetings will build our dog’s confidence. Through repetition, we are teaching him how to behave (just avoid and move along), and how not to behave (get over-excited, frustrated, lunge, and pull). He will be more calm because he is not waiting in anticipation of a highly charged encounter, either for play or for confrontation.

I try to set my dog up for success, and do not let him practice aggressive behaviors when meeting other dogs. The more he practices, the more aggressive he will be.

If my dog becomes agitated during a walk, I try to end the outing as soon as possible. Once in this mode, his adrenaline levels will be high for a fair duration, and he will likely react aggressively to all the dogs that we meet. In this state, he will no longer be capable of learning, and will only be practicing dog aggressive behaviors.

Dog-to-Dog Aggression Tip 5


Protect our dog from rude dogs and rude people.

I usually keep my dog away from people and dogs with weak energy (e.g. fearful, excited, or frustrated energy). In addition, I also try to keep other dogs and owners from coming into my dog’s space. I say a quick ‘hi’ to the people I meet, and move on.

If people with weak energy stop and want to meet my dog, I ask them nicely to please move on, because my dog is easily excitable.

It is fine and good to let a dog meet people with calm energy, but make sure to let them know how to best meet our dog. In particular, turn away when he jumps, no quick movements, and no petting from above.

Dog-to-Dog Aggression Tip 6

Use positive interrupts and keep encounters short.

While greeting another dog, we want to positively interrupt our dog every so often, and get him to refocus on us. Do this as many times as necessary, so that our dog does not get over-excited, and lose control of himself.

Whenever my dog is meeting a new dog, I interrupt him after a very short duration (2-3 seconds). I quickly move or jog away from the other dog, while giving the positive interrupt command, e.g. Hey, hey. Initially, I may have to lightly tug at my dog while moving away. I make sure to treat him well for moving toward me on a loose leash.

If our dog is too obsessed to move away and is strongly standing his ground, then we have waited too long to initiate the interrupt. Positive interrupts are also useful for dealing with human greetings, and getting our dog away from a dirty or unsuitable area.

The key to successful positive interrupts is to catch a dog early, before he starts to obsess on another dog or object.

Dog-to-Dog Aggression Tip 7

Be aware that our dog’s natural look may trigger an aggressive reaction.

Some dogs, for example Spitz-type dogs, have a natural look that may appear dominant (ears up, hair out, tail up). This dominant look may instigate other dogs to respond in kind, and start posturing as well. Conflicts may occur, and if neither dog is willing to back down, this may lead to a dog fight.

If I am unsure about a dog greeting, I just move on. Better to be safe than sorry.

Dog-to-Dog Aggression Tip 8

Desensitize our dog toward other dogs.

The problem with dog-to-dog aggression issues, is that in regular situations the “other dog” stimulus is too strong, and environment is too unstructured for any learning to occur. Often, our dog overloads quickly and becomes reactive, because the other dog is too close, is staring, is hyper, or is charging toward us.

In the desensitization process, we do training in a quiet, enclosed environment, and start with a very weak version of the problem stimulus. In terms of reactivity toward other dogs, we can use distance to weaken its effect.

In this way, we also weaken the strength of our dog’s reaction, so that he will be calm enough to listen and learn. This is necessary, to create opportunities where we can begin to teach our dog to be calm and relaxed, while in the presence of another dog.

I did quite a lot of dog-to-dog desensitization sessions with Sephy, when he was young, at our local SPCA. The trainers there had many balanced, friendly dogs, that we could do training with.

First, the trainer would engage the other dog in training exercises, so that he stays in a fixed position, and is not focused on Sephy (i.e., no eye-contact). Both dogs are on-leash.

I take Sephy a far distance away, far enough away that he is still calm and able to listen to me. Then, I get his attention by calling his name. If he looks at me, I praise, and treat him for behaving well. Sometimes, I also ask him to do very simple commands, e.g. Sit.

I let Sephy sit and watch the other dog as long as he is calm, and willing to give me his attention when I ask for it. Once we are both comfortable with this, I move one step toward the other dog and repeat the Focus and Sit exercises above.

Do not move too close to the other dog, too quickly. If we move forward too fast, our dog may become reactive, and will no longer be able to give us his attention. At this point, I no-mark Sephy (uh-oh) and move back a few steps. Once we are far enough away, I try to get his attention again. When he gives it to me, I stop, praise, and treat.

Note – for desensitization to be successful, we want to keep our dog below his instinct threshold as much as possible.

I always try to make sessions short, fun, and rewarding. This helps our dog associate other dogs with being calm, and with positive experiences. I make sure to stop before my dog shows any obsessive behavior, and long before he becomes aggressive. Once a dog becomes reactive or aggressive, it is usually best to end the session soon after.

As we make progress, we can slowly increase the strength of the problem stimulus. For example, we may allow the target dog to start moving around, or we may allow him to play with his handler.

The desensitization process can be long and difficult. Dogs with lower instinct thresholds (the point at which they lose control and switch to instinct) will be harder to desensitize. However, consistent practice will also help to raise this threshold.

What to Expect from Dog-to-Dog Aggression Training

Do not expect too much, too quickly, from our dog. Make sure to treat and praise him very well, if he voluntarily engages in avoidance maneuvers, when there are other dogs around. This includes looking away from the direction of the other dog, smelling and exploring the environment, or looking at us for direction.

Initially, treat and praise even small avoidance moves, for example looking away for just 1 second. If a dog will not accept treats from us, then he is too far gone and it is best to lead him away. Treats are only effective for shaping behavior when our dog is still thinking, and not operating on instinct.

If we keep practicing desensitization exercises, and teach our dog how to behave with other dogs, he will improve. As he matures, he will become more confident, be less dog aggressive, and be more comfortable around new experiences.

    Hi, My female Kelpie 8 yrs old is a beautiful natured dog who has been non aggressive to any dog at all before , but recently i brought another pup, a female Mastiff into our home and she plays non stop with her and has no aggression towards the puppy ,She will walk with no problems and listens to all commands , But when we go to the of leash area dog park she wants to attack every dog that comes near , I don`t think it`s her being protective over the pup because the pup wonders off to play and she will still be aggressive towards any other dog that comes near her still . I have friends that bring their dogs over to my house and they play together with no aggression at all.
    What are your thoughts on this ?
    Regards
    Danny

    • shibashake says

      Before you got the puppy, how was her behavior at the dog park? Is that an enclosed dog park? If you bring her to the park without the puppy does she act the same way? How often does she go to this park? Did anything unusual happen at the dog park?

      I have friends that bring their dogs over to my house and they play together with no aggression at all.

      Was she previously familiar with your friends’ dogs?

      I know that my dogs are a lot more confident and sure of themselves on home turf. They also feel very safe there. On the other hand, the enclosed dog park environment can be very high stimulus and can be stressful for a dog. There are often many strange, new dogs around, engaged in chasing, wrestling, and other high energy behavior. Usually, there is not much structure or supervision. My Shiba Inu picked up a lot of bad habits at the dog park, and his behavior and social skills suffered as a result.

    Hi, I have a five month old female pit bull, who is currently at the vet now getting spayed, and she is perfectly fine with the three other dogs I have in the house. but as soon as we go on a walk, and she sees another dog, she pulls, lunges, and barks like crazy. I try to pull her away and tell her no, but she pays no attention to me. But I have noticed, that If I go up to the dog and associate then she is perfectly fine with that dog. I understand she is getting over excited over the dog, which can lead to the aggression. but I don’t understand why she acts the way she does. I just want to be able to take her for a walk and pass dogs without any issues. and I would like to get it fixed now since she is still a puppy, please, I need help!

    • shibashake says

      My Shiba Inu, Sephy, was a pretty reactive dog when he was young. He is curious and very dog focused. Also, at the time, he was an only dog. As a result, when he saw another dog during walks, he would get really excited and pull to get over to smell and possibly play.

      However, since he is on a leash, he is prevented from going. His excitement becomes frustration and he pulls harder and starts of vocalize. Ultimately, he redirected all of that frustrated energy onto the leash and started to do leash biting.

      I helped Sephy to be more calm around other dogs by doing dog-to-dog desensitization exercises. We did desensitization training in a structured environment, under the guidance of a professional trainer, and with trainer chosen dogs. I used distance and barriers to create neutral experiences during our regular walks. We drove him to quiet, low stimulus areas to walk, and did it during off hours as necessary.

      I talk about what I did with Sephy in the article above. However, just like people behavior, dog behavior is complex and will take time, patience, repetition, and consistency to change.

      https://apdt.com/pet-owners/choosing-a-trainer/

      The most important thing with Sephy is not only to maximize positive events, but also to minimize reactive episodes. Reactive episodes will significantly set back our training, undermine his trust, as well as cause him to associate other dogs with frustration and crazy behavior. Therefore, I had to manage his environment carefully and set him up for success by not exposing him to situations that he is not yet ready for.

    okay so, Me and my fiancé own a pitbull Australian shepard mix, and he has food aggression with only one of the other dogs, I am wondering if it’s a dominance thing toward him or is it just the fact that she gets to close to him… I have done everything I could, did research…and yet no result has appeared…

    • shibashake says

      How many dogs are there? Which other dog is he food aggressive with? Age? Breed? Temperament? How long have they been together? What is their history? What are their daily routines? What are their interactions like when there is no food? What retraining exercises have you tried? For how long? What is the situation like during feeding time?

      With my dogs, I set up clear dog-to-dog interaction rules and I slowly teach each new dog what the rules are. I supervise well during meal-time to make sure there is no stealing and that everyone is following the rules. I try to set my dogs up for success by managing their environment, and not exposing them to situations that they are not ready to handle. I supervise closely and redirect questionable behaviors *before* they escalate into anything more serious. More on what I do to help my dogs get along.

      However, dog behavior is very context dependent, so a dog’s past history, temperament, routine, environment, and more will all play a role. Things become even more complicated when there are multiple dogs involved. This is why in dog aggression cases, it is usually best and safest to get help from a good professional trainer/behaviorist.

    I own a Shiba Inu (Leon). He is a great dog except for his aggression towards other dogs, and his tendency to pull when on leash. There are a few dogs that he knew as a puppy that he still gets along with. But any new dog we pass on our walk he immediately stands guard and will attack. (He once slipped off his collar and tried to pick a fight with a great dane)
    There has also been an instance where we came across a dog unleashed and he attacked that dog as well. It scares me now more than ever because I usually have my 2 yo son with me. We switched to an easy walk harness, but nothing seems to help, he still lunges at other dogs.
    He has always been very hyper, so not going on a walk isn’t an option. Not sure what to do at this point.

    • shibashake says

      I did dog-to-dog desensitization exercises with my Shiba and that was helpful. I talk more about desensitization at the end of the article above.

      With Sephy, management is key. The more structured, positive, and calm experiences he has with other dogs, the more confidence and trust he gains, and the better his behavior becomes. However, reactive episodes (e.g. where he lunges or loses control) will undermine his trust, significantly set back training, and worsen his behavior.

      Therefore, I need to manage him carefully so that I do not expose him to situations that he is not ready to handle. I drive him to quiet trails if necessary, and we walk during off hours, etc. I use distance, barriers, and more to weaken the other dog stimulus and set him up for success. At the same time, I do desensitization exercises in a structured and controlled environment, with a trainer, to help raise his reactivity threshold.

    Hi,
    Thanks for your article. I thought it was helpful, however I do still have some questions. I have a three year old male Texas Heeler (Australian Cattle Dog and Australian Shepherd cross) who is extremely reactive towards other dogs (and people in some instances). He was from a backyard breeder and has genetic fear aggression issues. Dogs (big or small) who show up on walks are instantly growled and lunged at (interestingly, he doesn’t bark). Sometimes he will hide behind me as they approach before lunging out. I never allow interaction with unknown dogs. He pulls like crazy on the leash, but once the dog passes us, he is completely fine. People can walk by and, as long as they say nothing to him, he doesn’t seem to care (if a person does speak to him, they are immediately growled at). This makes walks very stressful. Would you please offer me some advice? Sundance (the dog) doesn’t like other dogs… period, but he can be around them (like in a house or in someone’s yard), though I have to be alert of his body language and make sure no toys or food are around. Thanks again for taking the time to help me.

    I look forward to hearing from you.

    • shibashake says

      In terms of other dogs, I create distance to weaken the other dog stimulus, I use barriers if they are available, and I also do dog-to-dog and dog-to-people desensitization exercises to raise my dog’s reactivity threshold.

      The more calm or successful events my dog has in the presence of another dog, the more confidence he gains, the more he associates other dogs with positive events, and the better his behavior becomes. Similarly, reactive events (where he becomes fearful and starts lunging) will undermine that confidence, significantly set back desensitization training, and cause his behavior to become much worse.

      Therefore, it was very important for me to minimize the number of reactive episodes that my dog has. To do this, I manage his environment carefully, and I make sure not to expose him to more than he can handle. I drive him to more quiet areas if necessary, we walk during off-hours, etc. I need to start small, and in an environment that sets him up for success. As he progresses with desensitization and gains more confidence, then I can very slowly increase the environmental challenge.

      Desensitization exercises need to be carried out in a very structured and specific way, so it was helpful for me to get guidance from a good professional trainer/behaviorist, especially in the beginning. We did desensitization at our local SPCA, under the direction of a trainer, and with trainer chosen dogs. I talk more about what I do with desensitization and creating neutral experiences in the article above.

  7. CJ says

    We have had our malinois for four weeks now, she is a 6 year old rescue dog and until she has been settled in her new home we have been trying to avoid other dogs until we could take her to a socialisation class. .
    At first we thought her problem was that she would be aggressive towards other dogs if she was on the lead and the other dog was not (despite our efforts to keep her away from other dogs this has happened a couple of times where the other dog has been off the lead and trotted right up to us. In one case she knocked a newfoundland to the ground, in the other she snapped at a boxer. Neither dog showed aggression towards her at all)

    We have been taking her to a field where we have been letting her off the lead to run around, since she needs plenty of exercise we’ve been there about an hour each day, there’s plenty of space to avoid other dogs and you can easily see all around you. So we can see other dog walkers before she can and avoid them easily. She’s good on recall and always comes back to us. She did this even when she saw a Black lab she came back when I called.
    Unfortunately she did not come back to me when she saw two dogs that I had failed to see because they were hidden in the trees. She’s as fast as a greyhound so she was over there in an instant. I couldn’t see what was happening due to the trees but I heard the other owner shouting. She’s gone over, started a fight and from what I can tell, injured the other dogs leg.

    She was rehomed shortly before we got her but then taken back to the shelter, we were told this was because she was fighting with that woman’s other dog. This woman had her for three weeks and couldn’t stop her fighting. We were lead to believe that this was just a problem with that specific dog. From what we can glean, it is every dog. Unfortunately we live in a built up area. We can’t avoid other dogs, but I’ve been doing everything you said in this article about moving away from the other dog if I see them on the street. We can’t distract her with treats as she has little interest in food.

    Any advice would be seriously appreciated. We are not letting her off the lead again. And before she goes out again we are getting a muzzle since we can’t guarantee that another dog who is off the lead won’t come up to her. I wasn’t nervous about walking her before, I’ve dealt with dogs that have bad socialisation skills so I’m pretty laid back when avoiding other dogs. Now I’m worried about her hurting other dogs. Please,Any help to avoid any harm to someone else’s pet would be really appreciated

      With my Shiba Inu, I did dog-to-dog desensitization and counter-conditioning exercises to help him be more comfortable around other dogs. We did the exercises in a very structured and controlled environment, under the direction of a trainer, and with trainer chosen dogs.
      https://www.aspca.org/pet-care/virtual-pet-behaviorist/dog-behavior/desensitization-and-counterconditioning

      The key with desensitizing Sephy is in managing his environment. I want to not only maximize positive and controlled events with other dogs but also minimize bad or reactive episodes. The more calm and successful experiences Sephy has in the presence of another dog, the more comfortable he becomes, and the more he associates other dogs with something positive. Similarly, reactive events will undermine his comfort level, significantly set back training, and worsen his behavior. I talk more about what I do in the article above.

      For dog-reactivity issues, I would get help from a good professional trainer who has access to dogs that can be used during training. We did training at our local SPCA and it was great because they had many different dogs that they can use to help Sephy with desensitization. In addition, the trainer helped us to keep things safe for everyone, and ensured that we carried out the steps for desensitization in an effective way.

    Thank you so much for this article. I have a 1 yr old rat terrier chihuahua mix that is in obedience class right now, and although I was told his aggression would be addressed, it is absolutely not (which is quite frustrating). My dog has aggression issues with people as well, and any doors that go to the outside, and a male member of my household (whom he barks at agressively and attempts to bite whenever he comes home). This means he barks at strangers and dogs outside, strangers inside, and even a family member. I try to walk him calmly by but it does not work too often.

    Do you recommend this type of training for his aggression towards people as well? I have tried both positive reinforcement and negative reinforcement, but I must be doing something wrong for it not to work. I appreciate any help and advice you have to offer.

    Thank you!!

      With my Shiba Inu, I did desensitization and counter-conditioning exercises with other dogs and with people. However, the process requires a lot of management and must be done in a specific and structured way. To do it right, we did private sessions with professional trainers at our local SPCA, with trainer chosen dogs.

      The more positive and calm experiences my dog has, the more confidence he gains, the more he associates other dogs with good things, and the better his behavior becomes. Similarly, reactive events will undermine that confidence, significantly set back our training, and cause his behavior to worsen. Therefore, an extremely important part of my dog’s training involved managing his environment carefully, so that I do not expose him to situations that he is not ready to handle. I want to not only maximize positive experiences, but also minimize reactive events.

      More on how I did people desensitization exercises.

      Dog behavior is very context dependent so each dog and situation are different. For something like this, I would get private lessons from a good professional trainer, who has access to dogs that he can use to help with training.

    I understand that judging a dog by its breed is predjustice but my 5 year old lab/terrier mix (65lbs) does not interact well with small breeds particularly chihuahuas, shit-shuz, and other companion breeds. If the small breed is calm and uninterested in my dog Foxy than everything goes well. But Foxy has been aggressive towards 2 chihuahuas now, one requiring medical needs and neither instances was she the initial aggressor. I need advice and help to train Foxy to relax and stay calm when small breeds become aggressive towards her. She is stocky and very strong with the potential to seriously injure or kill a small breed. Large breeds she is calm, playful, and sometimes intimidated by but I have never had to seriously correct her behaviors before with breeds her size.

    I don’t want anyone’s dog to get hurt, especially at the mouth of mine. But when a small breed acts aggressively I’m not sure I have the knowledge to help Foxy.

    I can’t help but feel that small breeds get away with being undisciplined and poorly trained too often because their size makes them manageable to pick up and remove from situations. That because they’re small they really can’t do much damage. But acting aggressively has lead my dog to dominate and inflict pain causing damage to a small dog. Someone’s baby.

    I need the dog on dog aggression to stop. I need to become a stronger leader with clearer expectations for my dog. But now everyte even we see a small breed, I become nervous.

      Are the little dogs loose?

      In general, I try to set my dogs up for success by staying away from reactive dogs and reactive people. I also did structured desensitization exercises with my Shiba to help him be more comfortable around other dogs. We did desensitization at our local SPCA, with a trainer, and with trainer chosen dogs. In this way, we are in control of the environment and the experience.

      The more positive experiences Sephy had with other dogs, the more comfortable he became and the more he associated other dogs with something good. Similarly, reactive experiences will undermine his comfort level, make him be more reactive, and significantly set back our training. Therefore, I manage Sephy carefully and I do not expose him to situations that he is not ready for.

      I talk about what I did with Sephy in the article above, including creating neutral experiences and desensitization.

    I have a 1 yr old boxer/pitbull mix who is fear aggressive towards other dogs. When he first came into my home, my 4 year old female Carolina dog was very aggressive with him–She is a very dominant dog with other dogs–she injured him pretty badly a couple of times. Since then my boxy boy gets very aggressive (snarling, barking, pulling, lunging) when he is around or even sees other dogs. I have not let him off leash near another dog since the first time I noticed this behavior. He is such a loving pup and very social, but because my other dog made him so scared of dogs, he assumes all dogs will be hurtful to him and immediately goes on the defensive. Is there something I can do to get him over his fear without him hurting another animal? He is great and gentle with my cats, by the way.

      I did dog-to-dog desensitization exercises with my Shiba Inu to get him to be more comfortable with other dogs. The key is to start small, with a very weakened version of the “other dog” stimulus and slowly build up from there. I talk more about how I did desensitization at the end of the article above.

      The more positive and calm experiences my dog has in the presence of another dog, the more confidence he gains, and the more he associates other dogs with good events. Similarly, reactive/negative experiences will undermine his confidence, significantly set back training, and worsen his behavior. Therefore, it was very important for me to manage Sephy carefully and make sure that I do not expose him to situations that he is not ready for.

      I talk more about what I do in the article above. Desensitization and counter-conditioning is best done under the direction of a good professional trainer. We did desensitization at our local SPCA where they had a variety of trainer chosen dogs that we used during training.

    I appreciate this article. I have a pitbull, about 4 years old (he’s a shelter dog so I am unsure of his age or background). I’ve had Max for almost two years and we have been through alot together. Together, we have gotten over a short period of male aggression and he welcomes male family members and friends with high energy affection! I continue to struggle with his fear/aggression while on walks and at the vet. He was with another dog in my home for about a year, previously, and the two always got along well. He and the neighbor dog run up and down the chain link fence in what a previous dog trainer described as play, and I do not note any growling or aggressive behavior. However when I walk Max, or take him to the vet, he exhibits behavior that I cannot distinguish between fear and aggression. After several encounters of this behavior, my anxiety is high in these situations which I know is bad and I try to control. I do my best to remain calm and ignore his behavior, but if it wasn’t for the halti collar I have on him I fear he will get out of my grasp and I don’t know what he would do. When he is in these situations, He begins to wine and not exactly growl, but make a noise between a wine and a growl. He then jumps, twists, shakes his head back and forth in what I think is an attempt to get out of the halti. I can’t observe any aggressive body posture such as a stiff tail or raised fur or low head and neck because he jumps and twists and pulls so hard. Today this happened at the vet. I remained calm and safely removed him from the office with the help of staff but the other owners had to move aside with their dogs from us and I was extremely embarrassed. As soon as we were outside he calmed down and I made him sit and relax a bit before we left. I did not yell or pet him, I remained as calm as I could. How do I tell if this is aggression, fear, or just over stimulation? He has never attacked another dog; he was great with my old dog; he is great with my cat; and he lived with other animals in foster care before I got him. Sometimes I feel if he was off a leash he would be fine but of course am too afraid to test that theory in case he hurts someone’s pet. I’ve spent $600 for 2 training sessions and the trainer simply said “he’s tough” after spending several hours working with her dogs and seeing no progress.

    I will try your tips on our next walk, with space and trying to remain calm myself. I can definitely say I do not exercise him enough, and that is something I am working on. Any other advice or pointers would be appreciated. Max is sweet, he loves to play and he loves me and I just want him to be happy and healthy. I would love for him to have a play friend; I work 2 jobs and live alone and I try my best to exercise him on my days off. A play friend may help with that but you can see my dilemma.

    Thank you.

    • shibashake says

      My dogs generally hate going to the vet because when they are there, they get needles poked into their skin, they get poked at, prodded, and more, by people who they do not really know or trust. My Huskies will pull back, twist, and do everything that they can, not to go into the vet’s office. When we get in, all they want to do is leave. It is difficult to get a dog to “enjoy” the vet, when what happens in there is usually pretty negative from their point of view. Some dogs may get aggressive due to fear (fear aggression).

      When animals and people are afraid of something, they prefer to get away from that thing. This is called the flight response. But if escaping isn’t an option, most animals will switch to a fight response. They try to defend themselves from the scary thing. So a dog can be afraid of a person or another animal but still attack if she thinks this is her only recourse.
      ~~[ASPCA]

      Some things that help with my dog for the vet-
      1. I need to control my own energy. This is very important. My dog is very sensitive to the energy of the people around him, so if there is stress, he will pick up on that, get even more stressed himself, and become even more reactive.
      2. I try to find a vet who is also calm and confident. The energy of the other people around my dog is also very important.
      3. This is harder to do, but an experienced vet who knows something about dog behavior and training helps a lot. There were a few vet visits that went well, and these were with experienced vets who knew how to calm my dog, and who were willing to spend the time to get to know him. This is much harder to find because most vet offices are under time constraints.
      4. For my younger Husky, I wait outside the office and have the receptionist come out and call me when they are ready. Then I go in by the side door so I don’t have to subject my dog to the added stress from other dogs, who are probably also feeling highly anxious.
      5. I have tried doing desensitization and counter-conditioning exercises, but that is difficult to do properly because I cannot get access to the vet or vet techs for training. Plus vet techs tend to change a lot, and sometimes even the vets.

      Desensitization and counter-conditioning exercises were also useful in helping my dog be more comfortable and calm around other dogs. I talk more about desensitization at the end of the article above. It was a crucial part in improving my dog’s reactive behavior.
      https://www.aspca.org/pet-care/virtual-pet-behaviorist/dog-behavior/desensitization-and-counterconditioning

      Finally, the dog training field is not well regulated, so finding a good trainer/behaviorist can be challenging. I first quizzed the trainers over the phone pretty extensively, then we did single consultations with a pared-down list. When we found some good ones, who actually understood the science behind dog psychology and had good experience with reactive dogs, it was very helpful. They taught me how to properly do desensitization exercises, how to read my dog’s body language, and helped me better understand the source of my dog’s reactive behavior.
      https://www.aspca.org/pet-care/virtual-pet-behaviorist/finding-professional-help
      https://apdt.com/pet-owners/choosing-a-trainer/

      I also read up a lot on dog behavior. That helped me to better understand and help my dog, and also helped me identify trainers who knew what they were talking about.
      More on where I get information about dog behavior.

      As for exercise, hiring a dog walker may be helpful. However, finding a good dog walker can also be a challenge.

    U just adopted a 6 ur old boxer , she’s pretty good with ppl a little afraid of guys and. Does not really get along with other dogs, her previous owner couldn’t keep her anymore cause she attacked twice one of her smaller dogs ( female as well) however, this didn’t till 7 months after she adopted her . I walked her for the first time and she mostly did pretty well until other dos would bark at her . I couldn’t help but to get nervous when one of the big dogs kept barking at her so I started walking in the shoulder of the street .. I couldn’t cross the st cause of traffic . Anyway the dog we encounter got out at the end of the fence and they sniffed eachother and walked off eventually… But my dog wouldn’t move on and I got scared there would be a fight… She med my friends dog the other day and something didn’t click with them two and a fight broke out and my grinds dog got hurt.. And today I was in my front yard and my neighbors little yappy dog got out charged right at my dog… My boxer charged too at that point… I’m pretty new at this and I’m trying to read some literature but I’m just nervous of loosing control of my boxer . She listens to me mostly… But I do loose her attention with other dogs… I really hope you can give me some input…. I would love to keep my dog… She’s so mellow and good with my kids … :)

      With my Shiba Inu, I did dog-to-dog desensitization exercises to help him be more comfortable and calm around other dogs. With desensitization, I start small, with a very weak version of the stimulus, and in a structured environment where I am in control. The “other dog” stimulus has to be weak enough that my dog is able to remain calm, and learn positive behaviors from the experience. I talk more about desensitization at the end of the article above.

      Successful, calm, and rewarding experiences with other dogs help Sephy to build confidence, learn good social behaviors, and form positive associations. Similarly, negative or reactive experiences will undermine that confidence, significantly set back our desensitization training, and worsen Sephy’s reactive behavior. Therefore I manage Sephy’s environment and routine carefully, so that I always keep him below his reactivity threshold and so that he is not exposed to situations that he is not ready for.

      With Sephy, we did desensitization training in a structure environment, under the direction of a trainer, and with trainer chosen dogs. The desensitization process can be counter-intuitive, especially in the beginning, so it was helpful for me to consult with a good professional trainer/behaviorist.

      To help Sephy stay calm, I also needed to control my own energy. If I got stressed, worried, or fearful, Sephy would easily pick up on my energy, get stressed himself, and become even more reactive. I talk more about my experiences with Sephy in the article above.

    I have a 6 month old pug. Every morning we spend about 30min to 1 hour at dogs park. There are 3 to 5 dogs she meets and play with them every morning for the past two months. They are all young female dogs so there is a lot energy but they get along really nice. However, there’s a 1 year old bulldog which acts like a real bully and attacks all of thee dogs from time to time. She is not too aggressive/strong, but she starts the fight every time. It’s same with my dog. First few times, she attacked my puppy, we stopped the fight and that’s it. Of course, after like 10 times, now my pug won’t run away any more but she stops and fight back. I try not to over protect her and allow her to socialize, but also I don’t want my dog to get hurt or learn to be aggressive. Any advices how can to protect a dog in a dog park from dog bully, but still not over protect her, or allow her to accept this type of behavior as normal thing at the park. Thank you so very much!

    • shibashake says

      Yeah, I used to take my Shiba Inu to the dog park a bunch when he was young, but we stopped going after a while. Dog parks are often very high stimulus, unstructured, and sparsely supervised. In addition, there is no proper separation of the dogs into appropriate and manageable groups.

      Sephy ended up learning a bunch of bad habits, and his social behaviors with other dogs worsened as a result. He does much better in smaller, structured, and highly supervised play-groups, with dogs that match his temperament and play style.

      I set up a consistent set of play rules and I supervise. There is absolutely no bullying behavior, I manage excitement levels, and I make sure nobody gets overwhelmed. This teaches Sephy good social behaviors. He gets to play and have fun, but in a structured environment.

      The key with proper dog-to-dog socialization is not only to maximize positive events and good social behaviors, but also to minimize negative events that lead to reactive and aggressive behaviors. The more positive and structured experiences Sephy has, the more confidence he gains and the better he behaves with other dogs. Similarly, reactive events will undermine that confidence, teach him bad social behaviors, and result in negative associations with other dogs.

      While Dog Parks can be fun, they also bring plenty of NEGATIVE interactions by forcing your pet to come up against dogs that might be overly stimulated, short-tempered, outwardly aggressive or otherwise badly managed. Smart Socializing means keeping your friend dog-tolerant, and that involves AVOIDING dicey situations where conflict can spark.

    Thank you for the article, I will start practicing what you have posted. I have a 6 month border collie/blue heeler mix who is just fine with both my other dog and my moms dog, but I took her to a dog park for the first time and she was extremely aggressive towards other dogs. Snarling, lunging, and backing away towards me which made me think she was fearful, but even a small weiner dog that was just as nervous as her even looked in her direction she was aggressive towards. I hope she gets better after following your tips! Any other advice would be greatly appreciated.

    • shibashake says

      Dog-to-dog desensitization exercises were helpful with my reactive Shiba Inu. The more positive and calm experiences that Sephy had with other dogs, the more confidence he gained and the more relaxed he is in the presence of another dog. Note, however, that fearful or reactive experiences will undermine that confidence, significantly set back retraining, and make him more reactive with other dogs.

      Therefore, I had to carefully manage Sephy’s environment so that I not only maximized positive and calm other dog experiences, but also minimized reactive or fearful episodes.
      – We did desensitization in a structured environment, under the direction of a trainer, and with trainer chosen dogs.
      – We start small and go at a pace that Sephy is comfortable with so that I always keep him calm and well below his reactivity threshold.
      – At other times, I make sure *not* to expose Sephy to situations or environments that he is not ready to handle.

      As for dog parks, we went to a bunch of them when Sephy was young, but he ended up learning a lot of bad habits there. Sephy does better in more structured and supervised environments, with a much smaller number of dogs. He does best in small playgroups with dogs that suit his play-style and temperament.

    Hello, I have a small beagle mix named Casper. He is about a year old and he is not yet neutered. He is not aggressive at all and he listens very well. I am a dog walker and sometimes I bring him along on walks. Well, I walk one dog and he is a Pitt/Lab mix and he is never aggressive on walks towards other dogs, not even towards Casper. Diesel (the Pitt mix) has an owner that works very long hours so I am there a lot and he asked if I could bring my dog on a play date and just let them play in the yard and the house since it was rather cold outside for a long walk. I agreed since it had never caused any problems before. His owner had told me that he gets aggressive about treats and food but toys should be fine. So I removed all bones, treats, and food from the area they would be playing in. Diesel is almost 2 years old and he is fixed. As soon as we walked in the door with Casper on a leash, Diesel cornered him and started growling. Casper rolled over to show him dominance and he kept growling. Diesel has a vibrating collar and I put that on him. They were fine for a little while, until Casper tried to pick up a squeaky toy from under me. Diesel growled and I gave him a warning verbally and on his collar and he did not stop. Casper picked up the toy and Diesel snapped at him and continued growling even after he had dropped the toy and rolled over and even yipped. Could this be because Diesel sees that Casper is not fixed and he sees that as a sign of dominance, or is it because Casper was showing that he was afraid? He did not even react to the collar. What should I do in that situation if it were to ever happen again?

    • shibashake says

      Some dogs get protective over their home area and over objects in their home. Does Diesel show any aggression over toys outside his house? Aggressive behavior can be caused by many different things. This article from UC Davis has more on dominance and aggression.

      True dominance aggression is very rare. Most often aggressive acts are based out of another type of motivation.
      ~~[UC Davis]

      With my dogs, I try my best to protect them from bad dog-to-dog experiences. Negative events may cause them to become fearful or mistrustful of other dogs, learn inappropriate social behaviors, and cause them anxiety and stress.

      It sounds like Diesel has some guarding behaviors, so if I were the owner, that is the thing that I would address. With my dog I did structured desensitization exercises under the direction of a professional trainer, in a controlled environment, with trainer chosen dogs. I also carefully managed my dog so that I do not expose him to situations where he feels he has to resort to aggression to protect his stuff. Reactive experiences will undermine his trust, form negative associations with other dogs, significantly set back retraining, and cause him to become more protective of his belongings.

      To help my dog I want to maximize positive and structured experiences, where he can learn good social behaviors and make good associations with other dogs. At the same time, I want to minimize aggressive experiences and events which will create negative associations, and undo all our desensitization work.

      Why dogs guard their food and toys.

  17. Christine says

    I have a mixed breed male (neutered). He has really been a great boy, and I am working with him to be a traveling companion. He is a little shy of people and children, but we are working on that and he is coming along well. He doesn’t seem to be aggressive towards cats, nor does he have a particularly high prey drive. He is very interested in new dogs, and any time we have visitors at the house he does well with them, the problem that I have run into is when we are out and about any face to face encounter with another dog turns very quickly into growling/snapping. I have started trying to work on this with him with some desensitization exercises. (ie. having him sit, down, stay when another dog is nearby) and rewarding him when his focus stays on me, rewarding him when he gives visible relaxation cues while in sit or down position. I am not sure if this is just a matter of stress and new experiences on his part or if this is the beginning of a real problem. Any advice would be greatly appreciated.

    • shibashake says

      Does this behavior only happen on-leash? When he sees another dog while on-leash, what is his reaction? Is he still relaxed or does he get tense? At what distance does he start to react, or is it only when they are face to face? Does he act this way with all dogs while on-leash or only with certain types of dogs? Does he approach the other dog, does the other dog approach him, or are both dog approaching each other?

      Face-to-face greetings can sometimes be stressful and confrontational, depending on the temperament and body language of both dogs. In addition, when a dog is on-leash, his freedom is limited which can introduce more stress to the situation because he is not able to move away or flee.

      In general, when out on walks, I teach my dog avoidance. We only meet dogs that we have seen a bunch of times, who show relaxed body language, are friendly, and are under control. I also observe each of my dogs closely, and I take note of what dog types they are most comfortable with, and what dog types they do not enjoy. For example, my Shiba Inu does not get along with dominant dogs. He also does not like new dogs sniffing his butt. Therefore, we only meet with relaxed and more submissive dogs, and I make sure they do not go into his rear region, until he gets to know them better. :D

      When it comes to dog-to-dog socialization, I want to not only maximize positive and successful interactions, but also minimize bad greetings. The more positive experiences my dog has, the more confidence he gains, and the more he views other dogs as friendly and non-threatening. Similarly, negative events will undermine his confidence, significantly set back desensitization training, and cause him to get more wary of other dogs.

      With Sephy, I managed his environment carefully, and I always try to set him up for success. We ignore most dogs during walks, we meet some that I am sure he will do well with, and at the same time we did desensitization training in a structured environment, with trainer chosen dogs. In this way, he never gets exposed to situations that he is not ready for, and he stays below his reactivity threshold, so that he can learn to be calm and to stay relaxed.

      Thank you for your very informative reply! In response to your questions, other than at our home he has not been introduced to new dogs off leash, and even the at home the introductions we have had are with puppies under 12 weeks. Generally he is curious about new dogs enough to go check them out while on leash, but I wouldn’t say that he is excited or wound up. I will say that a certain degree of wariness does seem to be present in his posture. The reaction so far is always when face to face, and I am not really sure what the trigger is for him, because they can be politely sniffing at each other for several moments and then I will see him tense up if I watch closely and from there I can still distract him and move away without any resistance. He is generally the one approaching, but he does not like a strange dog approaching him. Again thank you so much for the info!

    I have a 10mo th old Jack russell Pip he is very fearful of so many things he is tiny and as a small pup out on walks larger dogs off there leads would come up to him and get too close he now has built up a fear of other dogs and shows real aggression . My mum has a parson Jack russel who is 2weeks older than pip they were great friends always playful and good 2g. We didn’t see them for a 4week period due to my mums dog being neutered when we last saw them pip was awful he growled and when she got close he bit her you could see his fear he kept running and hiding behind us. I’m at a loss with him, he has always shown aggression towards us but this is mainly if he is touched whilst napping. Walking him is awful h is scared of cars and no pulls at them barking. I’m temped to try walking him with a muzzle so he can’t hurt anyone and can’t bark at everything but don’t want him to feel in more danger. We have been to ouppy classes he was always great until one day a new dog came they both had a real problem with each other I had to stop going due to work but now feel I’m stuck I don’t feel he could now go back he would be awful I’m starting to fear leaving the house with him .

      With my Shiba Inu Sephy, we did a lot of dog-to-dog desensitization exercises. Desensitization was helpful because it addresses the anxiety, and teaches my dog to be more calm and comfortable around other dogs. I talk more about our desensitization training at the end of the article above.

      With anxiety issues it is important for me not only to maximize successful and calm encounters, which help my dog to build confidence, but also to minimize bad encounters and panic attacks. Negative events will undermine my dog’s confidence, significantly set back training, cause him to become more fearful/anxious, and result in even more extreme behavior.
      More on how I desensitize my dog to scary noises (for example from the garbage truck).
      More on dog anxiety.

      However, dog behavior is very context dependent so each dog and situation are different. In addition, desensitization can be counter-intuitive and requires good timing, technique, and management. When I had problems with my Shiba, I did private consultations with several trainers. In this way, they can observe and evaluate my dog, help me come up with a good plan for retraining and management, as well as help me with timing, technique, and more. I find that private consultations are best for addressing behavioral issues with Sephy.

    Hi there,
    I have own a 1year old bitch PureBreed English Bulldog. I have had to leave her with close relatives for a couple of months now untill we find a new house suitable for her. We just picked her up, and I have notice a change in her behaviour. When she was with us, she was playfull, relaxed. I could take her anywhere with us, was good with other dogs as well as people. As the family members had her with their dog a (German Sheperd bitch) my dogs come back with wounds all over her face I swear she looks like shes been in a dog fight ring. Shes become very aggressive towards other dogs, and barks at everything now.
    Is there anyway to undo the damage? Please.

      With my Shiba Inu (Sephy), I helped him to be more calm and relaxed around other dogs by doing dog-to-dog desensitization exercises. The key thing with Sephy is to not only maximize positive structured greetings, but also minimize reactive encounters, where he loses his cool and starts to bark, pull, or lunge.

      I talk more about desensitization exercises at the end of the article above. I also talk about what I did to avoid reactive encounters.

      Dog behavior is very context dependent, and desensitization exercises can be counter-intuitive and complex. When I started retraining Sephy, we got help from several professional trainers. They were able to evaluate and observe Sephy within the context of his regular environment and routine. Together, we identified the source of his reactivity and then came up with a good plan for retraining. They also helped me to properly manage the desensitization training, and guided me on timing and execution, which are very important.

    My 2 yr old rescue lab mix seems to be getting dog aggressive. I have had her for 6 months and she was so sweet went to dog park every day and always played well. The park is closed. For the winter and now when she meets other dogs she seems to be aggressive. I feel she might not be exercised enough without daily trips to dog park and it’s hard for me to go on long walks in the very cold weather. I want her to be able to play at dog park again In the spring but afraid she may be a bully by then. I take her to dog friendly stores or wherever I can take her to keep her socialized but her hair stands up on her back now. I want to put her in a class but just had neck surgery and need to wait about a month. I don’t want her to become aggressive what do I need to do

    • shibashake says

      How was she when meeting other dogs on-leash previously? What was the context when she met other dogs previously and now – i.e., what are the differences? Was she on or off leash? Was it in the same location?

      One of the key things with socializing Sephy to other dogs is this – I need to not only maximize positive interactions with other dogs, but also minimize bad experiences.

      In the beginning, I tried to introduce Sephy to as many dogs as possible, but that turned out to be a mistake. This was because he was having a lot of so-so and not very good experiences, and he ended up being even more reactive to other dogs.

      What works best for Sephy is to do more controlled greetings and play, so that he learns good interaction behaviors from each experience. I still try to introduce Sephy to a variety of other dogs, BUT only in a structured, controlled, and positive way.

      Dog-to-dog desensitization exercises were also helpful for Sephy. I talk more about desensitization and what I did with Sephy in the article above. We do structured play, structured walking, and structured desensitization exercises.

      However, dog behavior is very context dependent, and things become even more complicated when multiple dogs are involved. Therefore, in cases of aggression, especially those involving multiple dogs, it is best and safest to get help from a good professional trainer. We visited with several trainers during Sephy’s difficult period.

    I have had 4 doodles for many years. All mellow and have gotten in routines and used to a simple way of farm life.
    They all are trained pretty well and get along. Each have a very distinct personality. Three of them are 6 and one is 11 years old. The 11 year old is Alfa of the group (and starting to fail) besides us humans are top Alfa). They are also all females.
    This past summer we adopted a unique little creature and she desperately needed a home. She is a mix Austrian Shepard and long hair terrier. Half the weight of the bigger girls

    She is a bit of a handful. Energetic and lively. She had come with zero social skills or training and was 9 months old when we got her.
    We have had her for 3 months now. Smart as whip. She has learned basic skills of demands and many tricks ( sit up- wave- high five- crawl-rollover- etc!)

    My problem;
    She is very pushy with the other dogs. She can get aggressive if she wants a toy. A few times the other dogs have layed into her- with respect- but have corrected her- and she wants to fight back and not back down. I’m worried about pack mentality if she doesn’t cool it. I’m not alarmed with any of these spats – yet. They don’t happen often. That’s what I want to stop before it could get out of hand.

    Any suggestions on how to handle this?

    I have a one and a half year old male dog, he is a teckel mix, we have had him since he was two months old. For the last few months he has been showing signs of aggression towards other dogs and towards people.

    The aggression towards dogs appears when they approach him too fast and I think he gets scared, although they do not show any sign of wanting to attack him. The problem is that he enters this attack-mode where he barks and bites uncontrollably, and I have yet to learn how to stop him. He has also bit me while trying to calm him down, as if he didn’t know who I was. I must mention that this does not happen with every dog, only with the ones that approach him too rapidly.

    The aggression towards people has come up in a number of instances. The most recent one is having guests over, it is really hard to stop him from barking at unknown people that come over, and if these people try to approach him he will not hesitate to bite. Also while trying to stop him from barking he has bit me because once again he had entered that aggressive-mode where he does not seem to realize who is touching him.
    Another situation where he was aggressive towards me is an older one. While trying to pick him up for a bath he will lay on the floor and begin to bite if picked up. This happens only when he realizes that I want to give him a bath.

    I personally think that all his aggression is fear-induced. Fear of other dogs, fear of new people, fear of getting a bath. Generally he is an active dog, he does play rough (we have yet to teach him how to not bite while playing, but these bites do not compare in intensity with those from when he enters his attack-mode), but overall loving and not unusual in any particular way. He is stubborn, but does not show other signs of aggression around the house (except for the bath thing).

    What advice could you give me? How could I make him more relaxed and not afraid of new dogs and people? Do you think obedience training could solve any of these problems? I have found that for the bathing problem I can make him go in the bathtub on his own with a treat, but if I try to put him in there by picking him up he becomes aggressive once again…maybe I am triggering some sort of fear?

    I eagerly await your answers! Thank you!

      Did anything change when this behavior started to show up? Was it a sudden change in behavior or was it gradual? Is he showing any other changes in behavior? Is he playing and moving normally? Eating, drinking, and eliminating normally? Have there been incidents with other dogs before this change? How was he with people and other dogs prior to the last few months? Was he relaxed and confident, or has he always been fearful?

      When there are *sudden* behavioral changes in my dog, I rule out physical issues first. If my dog has a physical issue or is in pain, her behavior will change because she is not feeling well and is feeling more vulnerable.

      After I rule out physical issues, then I can look at other possible triggers and come up with a plan for changing my dog’s behavior. To help my dog be more comfortable around people and other dogs, I do people desensitization exercises and dog-to-dog desensitization exercises. I talk more about dog-to-dog desensitization at the end of the article above. I also slowly desensitize my dog towards handling and grooming. More on how I bathe my dog.

      In terms of play-biting or accidental, I do bite inhibition exercises with my dogs to teach them to control the force of their bites. More on how I train my dog not to bite on people.

      However, dog behavior is very context dependent and aggressive behavior can come from many different sources. Therefore, each dog and situation will be different. This is why especially in cases of aggression, it is best and safest to get help from a good professional trainer.

      When I had problems with my Shiba Inu, we visited with several trainers. Each trainer observed and evaluated Sephy, and we came up with a plan for dealing with each of his problem behaviors.

    Hi. I had gotten a rottweiler male pup who is now almost 5 months old. I now got another rottweiler female puppy and there is a big size difference between the two. The male pup just wants the female to stay near him at all times and this offends the female. This usually causes the female to get aggressive. Even when they are playing the female ends up biting the male and making him scream in pain. I have to keep them separately because of this. What do u recommend I should do?

    • shibashake says

      With my dogs, I set up clear and consistent dog-to-dog interaction rules. In this way, they know what to expect from each other, what to expect from me, and what I expect from them in return. This creates certainty and certainty helps to reduce stress and conflicts. If one of my dogs needs some alone time, I make sure that my other dogs leave him alone. Each dog has a safe place that he can go to, to rest or chew on toys.

      When they are together, I supervise them well, especially in the beginning. I try to create positive and calm together experiences, and try to minimize negative interactions. The more positive together time there is, the more my dogs learn to be calm and relaxed together. Similarly, bad experiences will undermine trust and acceptance, causing stress and more conflicts in the future.
      What I do to help my dogs get along.

      However, dog behavior is very context dependent so each dog and situation is different. In cases of multiple dogs, there is even greater complexity. This is why especially in cases of aggression, it is best and safer to get help from a good professional trainer.

    I have a blue heeler “Percy” that I have had sense birth. I had no other dogs at the time so every where I went she was with me. I have an incredible bond with this dog. I would trust her with my life. She does anything that I ask of her and is my best friend. She listens, and is just an amazing dog that I could take anywhere and do anything with.
    Because we have such a bond she is extremely protective of me. Even around people she has to be in my lap or close to me but she never is aggressive to people, just dogs.
    Recently I got an australian shepherd “Fisher” who she thinks she is the mother of. She loves him and shows the same signs of protection towards him as well.
    Here recently we decided to breed him and we got another shepherd, a femal “maggie”
    This threw Percy over board because I spend a lot of time with Maggie and extremly baby her because like Percy I Have a strong bond with her.
    If I sit out in the drive way to love on all the dogs Percy will not allow any dog near me, not even Fisher whom she actually really likes. She isn’t mean and starting a fight with them. Just letting them know that I am off limits and when I do go to the other dogs she stays right next to me just to make sure.

    Recently this acts of agression have gotten much worse. Percy now has a death wish for maggie. She has gotten her down on the ground by the throat and I believe had no intention of stopping, but of course we broke up the fight. This has been the worse but she has been attacking her for a while now. With the last go at the throat being the most recent and worse attack she has done.
    I don’t want to punish Maggie by keeping her away from the other dogs. It’s percy but I do not know how to handle it.
    They are all outside with each other all day, none are allowed in the house and have houndreds of acres to roam on because I live on a farm.
    I do not want to get rid of Percy because I love her so much, but I love Maggie too and I’m not going to let her attack her like she does.
    Every time I witness an attack i try to show dominance over Percy and let her know what she is doing is not tolerated, but in this area she shows no signs of regarding anything I’m saying or doing.
    Do you have any advice? Any would be much appreciated.

      What helps with my dogs is to set up clear dog-to-dog interaction rules. When a new dog comes along, I teach him what those rules are. In this way, my dogs know exactly what to expect from each other, what to expect from me, and what I expect from them in return. This creates certainty, and certainty helps to reduce stress and conflicts.

      I do this right from the start so that I am fair and consistent with my dogs. I usually set up more rules and structure in the beginning, and then I can relax some later on as my dog matures.

      When I get a new dog, I try my best to keep routine and rules consistent with my existing dogs, so that there is as little disruption as possible. I want to maximize positive interactions, while at the same time minimizing negative experiences so that they learn to associate my new dog with good things and an enhancement to their life and routine. Therefore, I make sure *not* to cut down on people time with my other dogs.

      I supervise my dogs closely so that I can teach them what the rules are and redirect bad behavior *before* it escalates.
      More on what I do to help my dogs get along.

      I also do dog to dog desensitization exercises to help my dog be calm around other dogs and to teach them what to do in the presence of another dog. I talk more about desensitization at the end of the article above.

      When I am not around or am too busy to closely supervise, I keep the new dog separated. I do not let my dogs together unsupervised until I am very sure that there will be no negative incidents. This is not a punishment. It is a safety measure to keep all of my dogs safe, and to prevent my dogs from practicing undesirable behaviors. The more bad behaviors they practice, the more likely it will happen in the future, and the worse things will become.

      Based on what you describe, I would get help from a good professional trainer. Dog behavior is very context dependent, so each dog and situation are different. Things become even more complicated in a multi-dog household. In addition, while engaged in a fight, a dog may redirect that aggression onto nearby people, especially when we physically try to restrain him (redirected aggression). In such a situation, I would want to start off right and safe by getting help from a good trainer. With my dog, I also use management equipment such as leashes, gates, etc., to keep everyone safe.

    i have a walker puppy about 3 months old and i have a older dog and she attacked the older dog the other day for no reason and today while i was outside with the 3 month old puppy i also have a chihiua about 4 yrs old and she attacked him for no reason……… What could be causing her to be doing this

    • shibashake says

      Dog behavior is very context dependent, so when I want to identify what is triggering my dog’s behavior, I try to remember all the details of the situation. For example, what was the puppy doing prior to the incident, what were you doing, what was the older dog doing? Did the older dog approach the puppy? What was the body language of the puppy and the older dog? Were there any toys or food around? Were you close to the puppy? Anybody else around? Any other dogs around? What is the daily routine of the puppy? Have there been any play or interactions among the dogs? What kind? How did it go?

      When in doubt, I get help from a good professional trainer, especially in cases of aggression.

    I’m so glad I found you. I have a 8 months old Shiba “Hachi” and she is very social with human and dogs. She comes to work with me which is grooming shop and loves to play with other too. However the problem I’m having is I have 3 other mixed breed at home, they all get along but once in a while Hachi and one of dog would start fighting. Hachi become too excited when Bobby plays with her and she gets too rough and Bobby just wants out and hachi won’t listen. Then Bobby growl at hachi and she will start fight. Also they are free feeder out of one bowl but not at the shop. I would put hachi ‘ s food by my table and she gets overly protective the space with other dogs comes around even there’s no food. Today Hachi bit Bobby ‘ s ear and I’m afraid what would cost next. Please help.

      What helps with my dogs is to set up clear dog-to-dog interaction rules and play rules. During play, I supervise and throw in many play breaks, to manage my Shiba’s excitement level. He can get pretty extreme when over-excited, and overwhelm my other dogs.
      More on what I do during play-time.

      As for food, I follow the Nothing in Life is Free program, so all my dogs work for their food by doing simple commands, following house rules, following play rules, etc. Whatever is left over, I put in interactive food toys, so they work for that too. During meal-time, I supervise and make sure they give each other space. If one gets too close to another, I redirect him away.

      Big hugs to your furry gang! :D

    I have a Jack Russell x whippet . Sometime when I let him off the lead and he plays with another he gets aggressive by growling and trying to bite the other dogs neck whilst they are running . He does not respond to any commands when he is like this .
    Desperate for help as he is a lovely dog.

    • shibashake says

      Is this at the park? How is he when playing at home in a more structured setting? Is the other dog high energy/excited as well? Does he get this way with all other dogs or with just certain other dogs?

      When my dog gets over-excited during play, he goes rear-brained sometimes and no longer responds to commands. I help control this by managing his excitement level. I have play rules, create a structured play environment, and throw in many play breaks.
      http://shibashake.com/dog/second-dog-introducing-a-second-dog#play-time

      The enclosed dog park environment is too high stimulus and unstructured for my Shiba. Therefore, I do small play-groups at home, where I can properly structure the environment. I pick dogs whose play-style and temperaments fit well with Sephy, and I supervise closely during play to manage excitement levels, and make sure that everyone is following play rules. In this way, everyone has a good time, nobody gets overwhelmed, and play does not escalate into aggression.

    My dog, Siberian/Alaskan Malamute mix has been attacking my poodle, we have other dogs but doesn’t attack them only this particular dog when we are at home. My poodle is usually frightened around her for no reason and I don’t know if that is what triggers the aggression. We try to let my dog (poodle) be comfortable around her but we decided that it is probably bad and that we have to let them get comfortable at their own pace or she (Siberian/Alaskan Malamute) might be frustrated. She isn’t aloud to be around her when she is alone because we can’t trust her so it’s made our life very difficult. Also, when she is out walking she wants to attack other dogs or just growls at them but they just want to sniff her tail and if any dog sniffs her tail she quickly growls and we tell her “no” or “bad dog”, but she is very well with her commands. I try to avoid dogs when I’m out walking with her. She sometimes doesn’t listen to the commands at home, I don’t know how to make her listen to the commands established. She attacked a German Shepard (my brothers girlfriends) and left him a wound. Of course, we weren’t around but she only responds to my dad as the pack leader but I don’t know if the whole family has to be understood as the pack leader or just one. I try to become her pack leader but I think she believes she is the pack leader of us. We try to set boundaries and rules but she is stubborn and doesn’t listen sometimes. What do we do? How do I fix this problem, I don’t want it to be too late, she is four years old and I know I’m a horrible owner because I don’t know the breed or understand it but I love her to death and been learning about her breed and try to cooperate with her. Our past is the reason why we are inseparable. I try really hard and would do anything for my dog. All suggestions are welcome and even criticism.
    Side note: When my dog was a puppy, my other poodle who was sixteen at the time, growled and barked but aggressively like she was about to bite when she sniffed her tail when I tried to introduce them. I don’t know if this is what made her hate other dogs. Ever since then she has never been friendly with other dogs.

    Hello, I’m on the verge of a melt down. I’ve just recently taken in a 3yr old Chihuahua mix. Her owners could no longer take care of her, plus she lived outside and it was getting cold. So, being the Dog lover I am, I took her in expecting no problems, seeing as how her owner had said she had no issues towards other Dog’s or Cat’s.

    But upon getting her home, I am mortified to see that wasn’t the case at all. My Youngest Pup Katsu, who just turned a year old in October. ( He’s a medium, to small Dog. Dachshund and Beagle. ) He’s overly excitable, and loves to play. He’s a little loud, and I think he startled her a bit. That started her whole, snarling and snapping, and growling fits. She’s also not very fond of the Cat’s. I have a 7 year old Chihuahua mix, who is very small. And I’m afraid she’s gonna lash out at her soon.

    She also has a bit of food aggression.

    I don’t think her current owners, had allowed her any interaction with other Dog’s at all. She’s fine with people.

    I don’t know what too do…. I don’t want to have to be the bad guy, and find her a new home…. Can you please, help??

      Dog behavior is very context dependent, so each dog and each situation is different. In cases of aggression, it is best to get help from a professional trainer who can visit with all of the dogs, observe them in their regular routine and environment, read their body language, and provide safe guidance on how to retrain the problem behaviors.

      I help my dogs get along by-
      1. Setting up clear dog-to-dog interaction rules. I teach each new dog what those rules are. In this way, my dogs know exactly what to expect from each other, what to expect from me, and what I expect from them in return. This creates certainty, and certainty reduces stress.

      2. I want to create positive, calm, experiences together and at the same time minimize bad interactions. Success will help everyone gain confidence and learn to relax with each other. Similarly, stressful or fearful experiences will undermine that confidence and set back training.

      3. I supervise my dogs well, manage their environment, and set them up for success. I do not expose them to situations that they are not ready for and I do not leave them together unsupervised until I am very very sure that they can be calm together.
