3 of my dogs eat Sensible Choice--they like the chicken.
My little Riley has to eat Science Diet oral care, because he has a poopy problem, and my vet recommended it, and the problem has disappeared!!

We've tried a few foods, and this one seems to be the best for all of them (well, the 3 that eat it). We did Purina One for a while, but it made Kito throw up, and we tried the Chicken Soup food, but everyone had runny stools--not just in the beginning, but for a long time after switching. Sensible Choice seems to work the best for them. Everyone is healthy, no allergies, shiny coats, and they all eat it.
If I switch again, it would probably be to Canidae, Innova, or California Natural.
