My puppy likes to chew on my hand until its sore and I can't get him to stop what should I do?

Puppies will naturally play this way with their litter mates but with our fragile human skin this is not an acceptable behavior. Striking your pup will only aggravate the situation and yanking your hand away, allows him to win and become more excited with this game. Instead wait until he grasps with his mouth and without saying any thing simply wrap your hand around the pup's muzzle and force him to hold his mouth around whatever he choose to chew on, long past the time when he wants to release it. Remember there is no need to reprimand but you must be willing to hold his muzzle for 30 to 60 seconds. If you are consistent, you will only need to do this 5 or 6 times and your pup will find this kind of "play" distasteful.
