Dogs Evolved Special Cuteness Muscle

I saw a documentary once about people's relationship with dogs. Apparently there's a village in Africa where the people don't even like dogs; they don't feed them, they don't talk to them, they don't give them names, etc. But the dogs still come into the village, clean up scraps, bark when lions threaten the cattle, etc. They do what dogs do without any regard to how they are treated by humans.
