Try NutriSource. It is usually easy on dogs with sensitive tummies. No matter what you try you should consider getting your pup on probiotics and digestive enzymes. They help him to better deal with the food he has now and they help his tummy to not be so sensitive in the future, plus they boost the immune system. Human ones are fine and are usually cheaper than ones labeled for dogs. If you are willing to order online, Swansons has good products at a great price.
