Cows are not bred only to supply meat, they supply labor to till fields and provide manure for crops. The dog breeds used for food in those regions are bred specifically for food, no different than current domesticated animals. Its the lack of that understanding and diminishing the work that other domesticated animals do that cause the problem. Hell there are plenty of studies that show pigs are smarter than dogs, we use them for organ transplants and stuff. You can legitamately argue pigs are more innately human than dogs are.
