He's just playing, but you have to start setting boundaries now or he'll continue to bite and think it's OK. You need to have a toy ready for these occasions – when he bites, sternly say "NO" and stick the toy in his mouth. That way, he'll begin to associate "biting" with his toy, so use the same toy every time.
Comments on If my puppy keeps attacking me amd biting me (doesnt have teeth) will he grow to be agressive dog?
