Modern dogs are social creatures. They literally wouldn't survive in the wild. Even as far back as histories go, humans and dogs have had a symbiotic relationship.

To compare dog ownership to say, slavery or the like, is ludicrous. It's definite survival for the dog, and all too often survival for the human as well in the form of companionship, emotional support, and of course typical working dog duties.

I guess I understand your take from a logical, outside view. But not from someone who has ever lived with a dog.
