A odd thing most dogs do is they love to stick their head out a car window with
their nose in the breeze, but if you blow in their face they don't like it.
My dog often gave me a lick if blew softly in his face. That dog loved to lick, especially
when a pup. I remember when we picked him out, he of 4 pups came over and started
licking my hand. The others could care less.
I have read that pups lick their mothers mouth to encurage her to regurgitate. I kind of
think thats why even older dogs do the same to their master.
I have read that cats rub against their human to mark them as their own. So I guess
that makes the human the cats pet.
