and look up what ever eukanuba your dogs were on then look at some of the 5 star dog food ingredients you might be suprised at what you are paying $$$ for. I hate to be negative but Any type of Purina, Science diet and eukanuba are mostly corn. If your puppies don't like Natural balance try a different flavor or brand. There is even a sticky on here that you can email for free samples!!
