My dear, you've got a ways to go... You have to remain consistant and its a habbit that he's not going to learn to break over night. You have to keep telling him NO firmly (keep in mind he's still a baby)... I also, use to make a fist, rather than let my pup bite on my fingers. Its a lil harder to bite a fist rather than a finger, ya know

and she would eventually stop.
It is a form of play for them right now. So, with Meka... I use to let her do it, until it started to hurt... Then, I would tell her "OUCH" and she would soften her bite... It whatever works for you
