How do i stop my dog from bitting?

There are a few tricks to stop this, but remember patience is key as they are just babies and not very bright yet. The easiest thing to do is give him a toy everytime he starts biting, as he could be teething and just needs to chew! Wetting and then freezing a wash cloth is very helpful (if he is just teething).

If he is biting for no other reason than just to bite than try this: when he bites you grab his muzzle (gently!) and say no bites, or whatever you want to use, and release but keep your hand near his mouth. He will probably bite again but continue this until he finally stops biting and licks. Always praise him when he licks, even if he bites right after, at least he sort of gets it! Good luck, it takes some time just be patient and consistent - with this and all other training!
