Blue Buffalo pet food: Designed by a guy who lost his beloved dog to cancer. He created a natural food with mostly meat, sans the cancer causing agents in many popular brands. My Doberman Shepherd sheds MUCH less on this food, his weight's maintained, he eats less, poops less, and the vet says he has the teeth of a 1y/o. (he'll be 6 soon). It costs more per bag than store brands, but a 20lb bag of Blue lasts nearly twice as long as the same sized bag of cheaper food.
