I recently switched Chopper from Nutro Natural Lamb and Rice to Nutro Natural Chicken and Oatmeal for sensitive stomachs. We switched shortly after he had the hair falling out episone because his stools were really loose. It has helped a bit, but not totally. What else would be gentler for him? And would it be good for the other dogs who have no problems on either of the foods. I wanted to try DVP but our Petco stopped carrying it. I think I can get it at a local feed store if you think that would be better for him and his belly.
