This is just my opinion, but there's something to be said for a food coming from a large research facility. Ages ago, when I showed horses, one of the most beautiful roan horses I can remember was named Purf Bar Midge. Funny name - but the "purf" stood for "Purina Research Farm" - he had been raised by Purina :-) I'm sure there's dogs, cats, lambs etc that have been raised in a similar manner. I'm not saying a human can't duplicate the balance of vitamins and minerals that come in commercial dog food - but if you were to pay yourself for the time it takes to make a balanced raw diet, I think it's way easier/cheaper/faster... and apparently safer...to feed a good commercial kibble.
