For dogs that like to bite their hands:
First: Never let the dog play with your fingers often.
Second: when the dog bites your hand, we should stop it at once, otherwise the dog will bite harder and harder.
Third: when we usually give the dog food, we don't give it. Let dogs snatch our food with their mouths.
