I had a dog with a very sensitive tummy. I never thought there was a connection with this and bloat. I was told the sensitivity to food was due to pancreatic enzymes. I put her on a mix of Wellness and Nutro Max and no table food and a piece of whole grain bread every morning as a snack. Mid day snacks were little pieces of cooked carrots or string beans or pea pods or a little bit of fruit. I think you have to keep a diary of what bothers the pup and you will find your diet through trial and error. My dog could take grains well but not alot of uncooked veggies nor much in the way of meat. I really believe this is individual to each dog and each owner must experiment with the food. Try reading the ingredients on the food and get to a mix of fruit and veggies and some protein. I really believe my old girl was bothered by too much fat or protein so the Wellness was good since it has alot of what didn't bother her.
