My mom's friend brought her five year old girl to our house the other day and Minnie bit her! I don't get it. Minnie has never shown aggression to anyone before (not even so much as a growl). She didn't bite the girl very hard, more of a scratch really. The mother said it was okay and she had been bitten before. I wasn't out there so I don't know if the little girl did something to provoke Minnie to bite her or not. Has your dog ever bitten someone? What did you do?
