I have a sixteen month old Burnese Mountain dog who has had sensitive stomach issues since we brought him home at eight weeks. We tried Nutro Lamb and Rice, Solid Gold Wolf pup, and finally Taste of the Wild Pacific Stream. After the TOTW recall, we switched him to Dogswell Nutrisca Salmon and Chickpea. It's more expensive than TOTW, but he's doing really well on it. Solid poops; the best we've seen since we've had him. Also, I add a tablespoon of pumpkin (not the pie kind) to his meals.
