I wish I could help! As much as I love dogs, I haven't had that much experience training them. Jake practically trained himself and Max came pretrained.

I have heard, though, that yelling "Ouch" really helps. I don't know - but maybe if you made a game of him biting his toys, then he would concentrate his energy on the toys and get the biting out of his system. Or do you think a flavored rawhid bone would help? If it was really yummy it should be more attractive than other things.
