My parents' yorkie does this. She is 7 years old and has grown up around me. She sleeps with my parents and if anyone, including me, comes into my parents' room and she is on the bed, she gets PISSED! She growls and shows her teeth, etc. I think she is just being protective! I tell her NO and make her jump off the bed, then I pet her and show her that I'm not going to hurt anyone and that it's "just me" and not some stranger.
Personally, I wouldn't worry about it. As long as he never hurts anyone... |
