dogs as children

We walked with Santi to the park today and there was a dog park. We watched them awhile outside the fence and I noticed that the owners talk just like people do about their kids. And talk to their dogs as if they are kids. And give them bottled water, which I don't give to Santi. They were asking each other, "How old's your dog?" and saying things about their behavior. It was just funny to me.
