Initially this was a sling off at dog owners who fed raw food to their dogs. When the originator of that term tried a raw food diet on her own dogs, she was so impressed that she began an internet list advocating the use of raw foods for dogs.

Please note that modern dogs of any breed are not only capable of eating the food of their wild ancestors, but actually require it for maximum health. This is because their basic physiology has changed very little with domestication despite obvious and dramatic changes in their current physical appearance and mindset.
