First of if the dog is healthy and doing well on the food there is no reason to change food but specifical why some do not like Benefull first and third incredient is corn and the fourth is wheat. This is a large precentage of the food being grain and not meat. Proteins from grains ared cheaper and more poorly absorped.

Dog Foods Help in making the choice easier
"I am a believer in keeping things simple. My dog food guides are The Dog Food Book and Dog Health & Nutrition for Dummies by Christine Zink DVM. Both are no nonsense and to the point. Neither gets caught up in "fads" unlike some of the others out there who say you are killing your dog if you don't feed a super (read: expensive) premium food.
Oh I tried to be a better dog mom. I tried most if not all of the foods listed in a certain magazine as being the 10 best (based on ingredients - not testing). I felt guilty for feeding a food that can be found in most pet food stores. I felt guilty unless I did the best I could for my dogs which meant feeding an expensive dog food. I also spent hundreds of dollars trying to get my dogs back into shape afterwards. For the most part, feeding these foods was a disaster for my dogs. I learned my lesson.
I feed what works for my dogs! Whether that's Purina, Iams, Eukanuba, Diamond or whatever. This is my advice for you. FEED WHAT WORKS!!! Don't let anyone guilt you into or suck you into buying a food based on a magazine's 10 best foods or prejudice towards certain dog food companies. If it works for your dog, then feed it. "
