I read this article in yesterday’s daily Woof Report, I think I need to make sure mom see’s this section right here:
Tongue & Chief
Puppies learn to lick to show respect to their pack leader soon after birth. By offering a greeting lick they exhibit a submissive social signal showing deference to dominant pack members. As puppies are weaned, they also may lick their mother’s mouth to request solid food, just as wolf pups licked their mother’s face to ask her to regurgitate food for them.
And here she thinks I’m just kissing her… I want more treats!
