Human food is dog food, dog food is human food. For the most part, anyway. You won't find me eating ol'roy lol

My point being though is that "human" ingredients are in dog food. You definitely can feed "human" food to your dog so long as it is nutritionally balanced. If you want to feed human food I suggest looking into feeding RAW and check out information concerning that diet and it will help you understand what nutrients your dog needs. Because just feeding hamburger and chicken each day every day won't cut it. You will need to supplement with other stuff
