I feed my two Nutro Lamb and Rice small bites. It makes it easier for Ripley to handle and Bella doesn't mind. LOL! I was thinking of changing to Innova EVO (even bought a small bag) but learned about the high protein content on another board and the mention of kidney problems. I went right back to Nutro L & R. Also tried Chicken Soup for the Dog Lovers soul for awhile but Ripley's poops were not good.
