Here is another neat trick I learned from Dogs 101 on Animal Planet lol.... get a frozen stick of butter and rub it on the back of your hand (has to be frozen so it doesnt melt) and when she tries to bite, tell her "NO", show her the back of your hand, and she will start licking it cuz of the butter hopefully, then praise her when she is just licking.....Unless you dont want your dog to be a licker hahaha
Anyway, Good Luck!
