This video is called "Bulldog puppy kissing the baby," but that's only the half of it: Yes, the little bulldog puppy gives the little baby little kisses and each kiss is probably the cutest thing you will see all day. But that's just the half of it.
What makes a movie (or, in this case, viral video—so a movie in the loosest sense of the word) worth the price of admission (which in this case is zero dollars, but go with it) is DRAMA. And this video is full of it: All this puppy wants to do is give the baby kisses and occasionally use her as a chew toy. All this baby wants to do is not share her spotlight and YouTube clicks with some dumb dog.
To be blunt, this is a baby diva.
