I cannot stand being licked by animals. I really really hate it. luckily, I have a dog who doesn’t lick. She’ll be 14 years old come August, and I can’t remember her ever trying to lick anyone since puppyhood. I suppose it would be too much of a coincidence that I, who hates to be licked, would just happen to own a dog who, contrary to what seems a natural instinct in dogs, doesn’t like to lick. So how did I “train” her not to lick me? It mustn’t have been anything overt, since I was too young (10) to bother with any sophisticated training methods (she also sits, and understands “over” and “under,” but that’s it.) and I don’t remember doing anything special. All I can think of is that perhaps licking is only somewhat instinctual, and is reinforced in most dogs by being praised by their owners for doing it. Do you suppose I’m on the right track? Eventually I’ll probably own another dog, and I’d like her not to lick too 
Some dogs lick alot. Some dogs don’t.
You can get alot of “training” in accidentally: Puppy licks you, you say “icky-poo” and push her away (negative reinforcement). Puppy does NOT lick and you pet, and scratch, and love on her till your fingers bleed (positive reinforcement). After a few tries puppy equates not licking with way more attention, and doesn’t lick.
Of course some dogs lick and lick even if you hook them up to a shock collar and bash them with a 2x4. And some dogs just don’t lick at all.
Most terriers and retrievers are very “mouth oriented” and tend to lick like maniacs. (Yes, I know many don’t lick, that’s why I said most)
So, yeah, elfkin477, you probably (inadvertantly) trained you dog not to lick when you were 10.
I trained my Ibizan Hound to lick. When I offer him a treat I say “big kiss” and that’s what I get. Unfortunately, he licks for attention when he wants something. Of course, if he didn’t lick, he would probably nose-poke. He has done that infrequently in the past, and I have anecdotal evidence that other beezers do that.
A lot of the reason that a dog may lick or not, other than the differences amongst breeds, is that licking, especially around the mouth, is a sign of submission. This stems from their history as wolves, where the cubs lick around the mouth of their mother to encourage her to regurgitate food for them when they are being weaned off her milk. Since only alpha wolves breed, any wolf that licks another wolf by it’s mouth is saying “i’m submitting to you”.
Other than that dogs might lick you if you taste good. LOL
