I have Champion show dogs, and Science Diet is a corn based feed, which means it main source of protein in corn. Even the snacks are corn based. My dogs are allergic to corn and their hair will fall out by the hands full. I would love to feed the raw diet, but it is to much touble. I feed Nutro(sensitive skin) this is a good quality food. It is more expensive than walmart brands, but you animal will eat less, poop less and have better breath and skin. Try it for a month, it is available at petsmart for 50.00 for 40lbs. Or Solid Golds Millinium. The solid gold is available at Pet stores or in small bags at For the Health of It. They also carry the Solid Gold supplements that are excellent. They will order you any of the solid gold products. All my life thought purina was the best you could buy, it is crap. Put a picture of my baby boy up. He's a sweetie. Taz is a champion in confirmation and a weight pull champion also, he is 8 years old in this picture.
