Why would you let a dog lick someone's, especially a baby's, face? That's disgusting. Do you know where that tongue was? I would also look as disgusted as the baby does.
Not everything, they can play in mud and whatever, I don't care, but facial contact with another animal's tongue is unhygienic. Play with the dog, sure, have them lick your hands and arms (which you wash before eating) and that's super chill. But if you licked your own butthole, ate cat poop/whatever-dead-animal-you-found-on-your-morning-walk or as a human gave someone a blowjob, would you kiss your child on the mouth directly after? Heavens No!
