Here is a site that sells dog food of all makes and brands. I like to use the site, because you can select a food and at the bottom of the page it lists all of the ingredients. Mine eats Natural Balance Ultra-Premium. It is shaped like a flat round instead of the usual shape and she seems better able to chew it. She loves it, too. Good luck!
