Oreo is also very licky! (Maybe it is a black lab thing ) Pushing her away made her even worse--she thought we were playing and licked more frantically! We figured out that she was being pushy trying to get our attention, and her training helped solve the problem a lot.

We taught her that sitting nicely was a good behavior that brought her attention and praise. Jumping and licking were behaviors that made us cross our arms, look away, and turn our backs (ignore her). She finally realized that she needed to sit to get what she wanted in the first place. So in effect, we replaced the licking with sitting. (Now, whenever she wants something really badly from us, she sits to ask "please!!!!")

Since Emerson's still a puppy, I'll bet he learns this in no time!
