I feed Innova EVO free choice. Chattie and Peppy each eat between 1/3 and 1/2 cup daily, Chizzie eats slightly more. We don't have a lot of doggie poo, but I might not be the right one to comment here. I probably scoop a ton or more a week from the barn.... so to me the Yorkie's poop is a teeny tiny little tootsie roll.
