my dogs are all on the BARF diet, and all 5 are extremly healthy, their teeth are pearly white, zippo tarter whatsoever, NEVER had a problem with ear wax, as in no ear wax at all. their coats are stunning, they went from fat to muscular, from lazy to a puppy, aging prematurly to actng like a puppy again, arthritis to none, etc........ etc.......etc... I could go on forever with all the changes we have had since the swich the way I see it, we dont eat commercial foods every day all our meals, and the same food too, for our whole life so why should we do this to our dogs???????????
