I think I must have one of the oddest puppies ever lol, my Lab never ever bit me when he was teething, he has never ever play bitten either, though when he does go mad outside he likes to jump up and have a nip, especially when we're all out in the garden, but there's not much more I can say, apart from what Fleur said, that consistancy is the key. We are getting there with my lab, he's not so nippy anymore.
Good luck =]
