Bailey is a little biter too.. When he gets too excited he'll go for the fingers and if your close enough, go for your face.
i'm not sure if this is beneficial in the long run but when he bites, I clap and say no! The clap snaps him out of it and he'll bite less or start to lick my hand.. :-/ but I guess I am just scaring him.. Maybe that's bad advice.. :-( i've yelped but with no success..
