The evolution of dogs and cats was similar to that of predators, so their anatomy is structured to essentially carnivorous diet.
Despite the outward differences of race, all dogs are descended from their wild ancestor, the gray wolf, with whom they share 99.8% of their genetic code.Therefor, just as their ancestors, our dogs and cats prefer eating carnivore, that’s why in terms of anatomical feature they have:
