We feed diamond natural chicken and rice. All my crew really like it and the chocolates are nice and dark chocolate, all are shiney and haven't had much problems with shedding, they seem to shed quicker, and coats come back in really nice. We fed purina for a long time, we had nothing but dry skin and itching, yucky ears, all the good stuff. All the problems are completly gone. I would highly recommend it. I am sure it doesn't work for all dogs, but is great here, and no corn!
I have fed Diamond and love it however started having a little bit of itching and switch pack to purina one lamb and rice for a while. I think they may have changed the formula and not as much omega fat. even the texture is not quit the same. hoping they fix that because other then that I love the food.
Diamond Naturals and Purina One Lamb and rice my favorites for my labs.
