Maybe you should try a harness that does not have to go over the head if that is an issue with him. A step in harness may be a better option. Does he ever wear clothing? I wonder if he has an ear sensitivity? I just mentioned in another thread that we have friends whose dog bite their daughter and attempted to bite another person before they found he had a serious ear infection and was in a lot of pain.
If the harness going over the head is really bothering him I would try a step in harness in order to make the process a happier event. He has already learned to hate the one you have. Some Yorkies do have stubborn streaks and forcing them can create more problems. If one method does not work try something else. If you have hit a wall in training then you have to find a way around it. It is not giving into him, it is just working with his particular personality. Dogs sometimes have fears and phobias that appear to manifest as aggression. |
