I sympathize. It is very difficult to have a pup like this. One of ours is very aggressive (non Yorkie). He is a rescue and came to us with a broken heart. ❤️

Please stop thinking of it as him hating you and attacking others because of it. It is the opposite. He LOVES you and wants nothing between you and him. That is why the behavior toward humans and dogs is worse around you.

Please, please, please do not add another dog into the mix right now.

Your boy is extremely confused because of the negative training methods used. If a pup barks and gets zapped, they will more than likely associate the zap with the object they are barking at, making the behavior worse long term. Only fear free and force free methods should be used from here on out. No mixed signals.

Your Yorkie needs to be kept away from any situations that could trigger him to bite or get overly upset. Doorbell rings? He goes to a safe space before you let the person in so he cannot bite. On a walk and he starts going off on something? You are too close to the stimulus and need to back off, find a distance that is tolerable to him, and start positive association (e.g. treat bombing).

You will have to manage his world for him because he can’t do it himself. It takes a lot of patience and understanding. Yes, drugs can help and boarded veterinary behaviorist are good. It is important to find the balance between quality of life vs. side effects, etc.

Part of the underlying issue in a case like this is a lack of confidence, especially when punishment has been used in the past. Victoria Stilwell should have some good resources related to confidence building. This would be the opposite of sending a pup into a group of dogs or people while hoping the pup can just work it out for himself.

I believe there is hope for your Yorkie, but realistically it will involve a massive commitment from you and a lifetime of management.
