I also was feeding Nutro until my furbaby developed pancreatitis. Now it is Hill's/Science Diet W/D. I thought he had a nice coat while on Nutro but it was nothing compared to what it is now. He has a beautiful coat. A friend of mine is going to college to become a vet tech and she told me over the weekend that they did dog food tests. They disolved food in water and found all sorts of things. The worst food was Kibbles N' Bits. Had hair particles floating around, along with other things I won't go into. The best was Science Diet. I would suggest this food over all others.
