Maybe those “idiots” as you call them have been hurt by dogs and their fear is very real for them. People dont know that your dog isn’t going to hurt them, since they dont know anything about your dog. It is rude to let your dog jump on people, and then act like it’s the person’s fault because they’re afraid. I also own a husky who likes to jump. It is very challenging to break him of this, but we still work on this behavior every day. People see a big dog coming at them, and yes they get scared..its human nature, not stupidity..

Get a bigger fence! Im constantly spending money on my dogs to make the garden dog proof, they are constantly challenging my unique ways to keep them in the garden, i have a 12 foot fence around it…concreate underneath it to stop them digging and they have pulled one of the pannels off. Baring in mind the panel wasnt stick out and was actually protected by another panel! More DIY to do now 😐

My girlfriend’s family have an adult rotweiler that is not agressive at all but has not been educated to be around people, the result is that he has to be kept segregated in a closed off bakyard. I feel very sorry for the dog because he is very sweet and friendly and clearly in need of attention and affection.

I have tried getting near but he bumps, pushes and jumps against me in away that I simply cannot move until someone throws him some piece of bread. Is there a way for this dog to be resocialized so he can interact normaly with people?

Collars or harnesses that might work or just a trick or something. I put up lattice and that worked for awhile until it got old and weak.

I help my dog be more comfortable around people by doing desensitization training.

During regular walks, I create neutral experiences by using distance. When I see “a trigger person”, I put enough distance between my dog and the person so that she remains calm and is still able to focus on me. I get her to do very very simply obedience commands and reward her very very well for it.

Desensitization training helps to create successful experiences for my dog in a structured/controlled setting. The more calm and rewarding experiences my dog has with people, the more trust, confidence, and positive associations she makes. Similarly, reactive experiences will undermine that trust and set back our training. Therefore, I make sure not to expose her to situations that she is not ready to handle, and that will trigger a reactive response. I manage her environment (e.g. walking off hours, driving to a quiet area to walk) and use distance to create neutral experiences.

Desensitization training can be counter-intuitive, especially in the beginning. With my Shiba Inu, it was helpful for me to get guidance from a good professional trainer who could help me with timing, technique, reading my dog’s body language, etc.
