When he bites you hard you have to squeal and cry,then he will feel bad,then stop. But if he wont stop at all you have spank him and scold him,then he will REALLY stop. You should also buy him a lot of chew toys so when he bites you,you have to run and get a toy.
Or just run to a really high spot. My puppy bites too and all these things work for me :s
