After re-reading the original post it doesn't really sound like a teething problem. I mean she's not just mouthing your hand and biting down too hard, she's attacking. I frequently deal with dogs that bite when being groomed. Some dogs bite no matter what you do but puppies that bite are usually testing the limits to see what they can get away with. It the puppy bit another dog and caused pain the other dog would snarl, bark or bite back and the puppy would learn that it can't get away with that behavior. On the grooming table here's what we do. It a puppy tries to bite we immediately grab his head or face, get really close and yell no or stop it or whatever. The puppy is usually so shocked he will just kinda freeze. Then we immediately praise the puppy for being calm and go back to what we are doing. Sometimes it takes a few times but almost always the puppy stops trying to bite and will just stand there (often wagging his tail). Also it is very important to not stay mad at the puppy. Only sound mad at the actual moment you are disciplining him. The instant he behaves praise him and be calm. You can't stay mad at him (even if you really are) because he will not remember why you are mad.
