Instructions
Take note of the times when your dog licks you to determine its motivation for doing it. For example, does it primarily happen after you have been gone from home all day or does it lick you when your attention is focused elsewhere? Maybe you need to give your dog more attention, such as brushing it, taking it for a walk or simply stroking its head while softly praising it.
Pull your hand or body part away from your dog when it licks and say "No lick" in a firm tone or get up and walk away after saying "No lick." These actions will communicate to the animal that you do not welcome the licking behavior.
Advise your guest that your dog may try to lick him. Instruct him to pull away and say "No lick" if your pet attempts to show his affection. An alternative is to place your pet in another area of your home or in your enclosed yard while you are having a guest.

While you may not mind this behavior, it could become a problem for guests that come to your home. Fortunately, you can discourage your dog from excessive licking.
