Dogs are brought to us as we see them today by over 12,000 years of eugenics. So what? People in the "wild" had a better chance of surviving with having dogs to hunt/guard their camp and the dogs had a better chance of survival by sticking around people and eating their scraps. It's a symbiotic relationship that isn't really relevant now, like I said - dogs have been living with and interacting with humans for 12,000 years. They're just as much as part of our lives and history as we are of theirs.
People like having things that they nurture and care for. Whether it's a kid, a lizard, a dog, a cat, a plant, a building - it doesn't matter. It's just how we operate. We're weird like that.
