You will have to find what is best for your dog kind of on a trial and error basis. When you decide to make a switch, I would recommend doing it gradually rather than all at once. How your dog (and his tummy and therefor poop) will just depend on your dog--vairious foods does not have the same effect on every dog accross the board. Some do better on the top brand organic foods, some dog's (like mine
) can't handle it. Just do your research and make sure that you supplement his diet as needed to provide for what the food you choose doesn't supply.
