Hey Chilli Dog what a cute name. My Precious does the samething, she bites our necks and ears. She knows it makes us laugh so she does it over and over,then she barks as if she's laughing with us. I thinks its so funny because she does it on command to my boyfriend,she goes for the neck then I'll say,"get the ear, get the ear" and he's laughing like crazy, "I'm gonna have califlower ears!" he says,Get him again! What a crazy little girly. They bring laughter into our lives, it's a good thing!
