Well as they say 'one man's junk is another man's treasure', or in this case dog's. You can't deny the fact that although dogs are mammals like humans, they have completely different dietary needs and sometimes can't even digest or process what normal human bodies can. I don't know what kind of dog food you're buying but I don't buy dog food made from "recalled foods, road kill, and euthanized pets." The bottom line is: dog food (the good kind) is much better suited to fulfilling your pet''s caloric and nutritional needs than normal people food can. Sure there might be "slaughterhouse scraps" in there, but that doesn't necessarily mean that it's bad for the dog. It's still organic protein.You or I might be inclined to call it gross, but dogs don't share our delicate, 'civilized' tastes. Dogs lick other dogs' buttholes for fun, remember?
