I have spent so much time, money, and effort into finding a dog food that agrees with my dog's sensitive stomach. He's also a very picky dog. But Nutro finally solved our problems. He tolerates all the Nutro products, but I have found that the product for sensitive stomachs works the best. He has a history of pancreatitis and since starting to use Nutro for sensitive stomachs, he hasn't had one episode of that painful disease. What a relief for both of us. I get to save on vet bills by sticking with Nutro and my dog gets a great tasting nutritional dog food!
