How old is he?
I am not an expert by any means, but we also rescued a yorkie with aggression issues so I know how you are feeling.
It sounds like he has some territory and possession issues that need to be worked on.
As far as the barking in the crate, This is how we solved the issue. Get him used to the crate throughout the day randomly. Then whenever he barks you can either use a spray bottle or a can with pennies in it. (we used the spray bottle) and spary at him. Spray and say "quiet" or No bark the first five or so times. Then when he does it after that you can just say the word first. If he doesn't listen to the word then spray after saying the word. This has word amazingly for ours and she now knows that when we say quiet to stop. Every now and then we need to get the spray bottle but never have to spray it anymore becuase she knows.
Good luck. I hope you can find a solution to this and don't have to find him a new home. |
