I fed NV raw at one point and then went totally all the way and now feed Prey Model Raw. I happen to think it's the best at least for my babies. Their teeth are clean and white (well my yorkie is, my collie was fed kibble for 11 years so hers are not clean and white but they are greatly improved since we started feeding raw) their coats are fluffy and shiny and they look so healthy and best of all, they now love dinner time. They used to be picky eaters but that's a thing of the past.
