Is he teething and/or has he had his remaining baby teeth removed?
It could be bc he's treating you like a litter mate and is using his mouth for the normal socialization process, could be that his teeth are bothering him, could be he wants to play, could be his chewing needs aren't being fulfilled.
We don't use negative reinforcement with our kiddos, but we really believe in re-directing and then positively reacting to desirable behaviors. With biting, we would redirect them to a chew immediately and keep doing it over and over, if needed. They actually caught on pretty quick.
Now that they're older, we do play 'hand games' with them now, but tried not to do it as much when they were puppies since they have a harder time understanding how it all works at that age.
