i posted this in another thread about biting.
hahah! that's a bully. the biting thing is HARD to break, but you just need to be really consistent. when my two were babies and biting terrorists, i would grab them, put them on their backs and hold them down until they stopped struggling. this would take such a long time, but eventually they will submit. everytime he bites you, just put him on his back until he gives up. after a couple weeks he will realize that he just gets dominated everytime and it isn't worth it because the game stops. when you release him you can offer him a toy and if he actually bites it and chews it, make a BIG deal about how good he is. you know they love praise. treat him when he is chewing his toys too, little pieces of cheese or some tiny training treats are good. eventually he will see which behaviors lead to treats and happiness and which lead to him being dominated. lol.
