here is the deal...i recently moved into another house and have noticed a change in my male bp's behavior. since the move a week ago he has been striking at us everytime we try to go take him out, our females behavior hasnt changed but his has. what can be causing this....here are some changes that has happened with the move:

the place i moved to has alot of dogs around outside due to the business i work for out of my home, rats do come around outside to try and get into the dog food we have in metal garbage cans...

could any of those changes affect his behavior? could he be smelling the rats and think its always feeding time?
