The nutrition in the home-cooked meal is very rich, and the owner will not give the dog something heavy, but will let the dog eat some rice or meat with broth. Dogs raised in the countryside will also eat some worms, or eat some bones when visiting guests, and they can also grow shiny. These puppies are very loyal and will guard at the gate to prevent people from hurting their owners. Dogs in the city are very delicate. If you eat human food, you are likely to have diarrhea. After all, the stomach is fragile and has adapted to dog food or canned dogs. These two kinds of dogs can eat whatever they adapt to, and they are both very happy.
Dogs in rural areas can run freely and are basically free-range. Those biting dogs may have been abandoned by rural people, or they may not be kept at all. Because rural people keep dogs just to look after their homes and protect their homes, they don't want to keep a very vicious dog. The dog in the city can enjoy it better, and the whole treatment is very clean. It is just a pet. Different dogs enjoy life in different ways, but they are all happy and healthy. There is no such thing as who lives better than who.
Just as people can adapt to different living environments, so can dogs. As long as they are slow, they will prefer the present state of life.
