I have a 6 month old Papillon who is absolutly terrified of my boyfriend! She begins it all when he comes around and starts to growl, then she barks and shakes because she is nervous. When i am not around and he tries to help her in her crate etc. she growls and nips at his hands, she has aucutaly bit him a few times. What can i do to help her calm down? Can she get trained some how? I dont know what to do please help!
