The issue of licking your face is often frowned upon due to the fact that worms are pased on this way to humans.
So long as you worm your puppy regularly throughout life I wouldn't worry. But when you get it from a breeder do not let it lick you unless you are 100% sure that they wormed it correctly to begin with.
