Very common for dogs, even packs of dogs, to roam the streets of Santiago.
Sometimes they get hit by cars, and someone will just toss them over against the wall on the sidewalk. I took a picture of this poor guy.
Poor thing, legs all up in the air, just tossed like garbage. Except I noticed he was breathing. So I rubbed his belly. Dog was momentarily startled, but then stretched out his front legs and did that loud "mmmmmmmm" that dogs to do react to belly rubs, and he went back to sleep. Not a very comfy position, but then he's a dog. Living the dog's life, not hit at all, just laying around.
