All dogs lick humans, unless trained otherwise. Many people believe that dogs lick humans because they enjoy the taste of a human's salty skin. Others believe that a dog licking a human is simply the dog showing affection (doggy kisses) to the human. In a wolf pack, a puppy licks the mother's mouth to stimulate the mother to regurgitate food from the hunt.

Dogs who compulsively lick their humans may be suffering from anxiety. There are a great many reasons why a particular dog may be anxious, so check out a Dog Training/behavior website (I like Cesar Milan the best) to learn more about dog licking behavior and how to reduce it.
