When your dog bites, leave the room for ten seconds. Go into another room such as a bathroom where you can shut the door, removing yourself from her presence. To your dog, your presence is a good thing and dogs quickly associate biting with you leaving, so will stop biting to keep you in the room. When you reenter the room, try to play with a toy to distract it from biting your hands. Be consistent and this will work quickly.

Good luck!
