Many Shiba Inu owners will tell you that “mine” is the first and most favorite Shiba word.
Shibas think that everything, including food, toys, the house, the neighborhood, and even their supposed owners, belong to them.
If not properly handled, many Shiba Inus, and indeed dogs in general can get aggressive about guarding their resources. Shibas are bred to be guard dogs so they have a strong guard instinct.
Dogs often guard objects from people because they associate people coming near them with their objects being taken away.

Resource Guarding - 'Mine!', Says the Shiba Inu

I was inadvertently teaching my dog that ...People coming near him = Loss of resources
When my Shiba was a puppy, he used to pick all all these dirty items from the street including tissues, pieces of plastic, etc. I did not want him eating the stuff, so I would always take them away from him. Ultimately, he started guarding his toys because he thought I would take them away from him as well.
I did not know it at the time, but I was teaching him that …
People coming near him = Loss of resources
When dogs show aggression and we back away, they also learn that …
Aggression = People backing away = Get to keep resources
What helped my Shiba most in breaking this resource guarding cycle is to help him re-associate people coming near him to be something positive rather than something he should guard against. In essence you want to retrain your dog so that he associates …
People coming near = More resources
In this way, your dog will seek out people rather than try to get them to back away with aggression.
Here are some resource guarding techniques that helped with my Shiba Inu.

People coming near = More resources
The key is to set your dog up for success and not expose him to situations where he feels he has to resort to aggression. The less he practices that aggression, the less it will become a habit.

Do not give your dog anything to guard.
Therefore, it is also important to take away all high priority items (such as bones and rawhide) and not give your dog anything to guard. Only give him very low priority items. Cut food up into small pieces and give those to him one at a time so he has nothing to guard.
Make sure that you always remain safe during the training process. Use leashes, baby-gates, or muzzles as necessary. My Shiba still wears a drag lead (with a flat collar) around the house so that I can more easily control him when I need to.

NILIF (Nothing in Life is Free) - Sit calmly before getting anything in return.
To stop resource guarding issues, it is also good practice to follow the NILIF (Nothing in Life is Free) program. This just means that your dog has to do something for you, before he gets anything in return including food, toys, going into the backyard, or coming into the house.
In this way, your dog learns that you are the source of all his resources, and he has to work for you to get what he wants.

Teach your dog that you are the source of all his resources, and he has to work for you to get what he wants.
If your dog is already aggressive and causing bite wounds as a result of resource guarding, contact a professional trainer.
Never try to take items away from an unknown dog. Even seemingly easy-going dogs may sometimes try to protect a high-priority item.

Shiba says, 'Come sit by me and give me more chicken!'
Hahaha – that is indeed a priceless expression! That is the thing with Shibas – they have such a large range of moves, moods, and expressions. Also, they can be such clowns – but very dignified clowns
As for the bird, that is a very high priority item so it is not surprising that Reptar decided not to exchange it for anything less than a pig’s ear. Gotta love that Shiba independent spirit
Sephy also doesn’t want to give up bones and such that he finds on the sidewalk. Usually I don’t use force to take things away from him, but if it is something dangerous like a chicken bone, then I hold onto the bone and tell him to leave-it firmly. He will do so, after a little bit because he knows I mean it. But I only do this very rarely.
In terms of playing chase outside – Sephy is the same way because he knows that I pretty much have no chance catching him outside – lol. But Shania is great at catching him and then rolling him on the ground. I usually get her help when I need to nab myself a Shiba.
Another thing that may help is to put a long line on Reptar when he is in the backyard. That way he gets his freedom, but you can easily get him if you need to. But Reptar is already such a good boy and so great with recalls, that I don’t think something like this is necessary. The bird thing is a rare occurrence, and super high priority. I think Reptar already did really well because he ultimately came in on his own.
LOL – love that picture. Looks like Reptar has grown a whole bunch. How big is he now?
Hello! Hope Sephy and Shania are doing wonderful. Reptar is trying to stay cool in this summer humidity and of course not at all trying to stay out of trouble.
I’ve noticed in a few of your posts and comments, you have mentioned that “drop it” or “leave it” if originally trained in the house, don’t apply outside. That makes a lot of sense. I am able to take anything from Reptar in the house with little threat of a chase game to follow, unless he gets a sock then I have to be a bit more clever.
Outside on the other hand, if he has anything in his mouth whether it’s a ball, a pine cone, a stone, or another toy, if I need or want to take it away, chase game ensues 100% of the time. He’s onto my bribery and trading of items, so he ignores me. For example, the other night all was well until I heard very upset bird noises in the backyard. Reptar who comes when called always like a good boy, comes busting out of the bushes with a baby bird. He was very proud of himself for such the big accomplishment and just wanted to play however he would not trade me for another toy, treats or any games I had to offer. It wasn’t until I got a pigs ear that he dropped the bird and came running in to m.
He certainly has me trained and it’s no good. How can I rectify this situation we have going on in the yard? any advice would be greatly appreciated!
PS, see his “I just played with a bird face” here. It’s priceless. http://colleenrcallahan.com/photos/bird.jpg
