My mom feeds Blue Buffalo to her dogs. When we got our dog, I just couldn't spend that much on food. I thought for most of the same ingredients that you find in other dog foods, why pay that much? I fed Purina Pro Plan Focus for Large Breeds up until the bag runs out then I am switching to Purina SmartBlend (the lamb flavor). Oliver loves both of them. Although, I am sure Oliver would love anything he was fed. If Sam's Club carried Purina Pro Plan, I would have stuck with that instead of switching.
