Hi everyone! I have an almost one year old bulldog named Sulley. When we got him at 5 months we were feeding Purina Pro Plan. I started to notice his wrinkles getting bad, ear infections, paw biting, etc. I found this forum and slowly switched him to Nature's VarietyInstinct Chicken and he got even worse...soft serve stools, red face, red tummy, etc. So I slowly switched him to Nature's Logic Lamb, while his stools are better his face, tummy, paws, and ears are getting worse. I am now thinking it might be the chicken. What do you think? I cannot tell if it's the grain or the poultry. I was thinking of trying Go Natural Salmon next, but that has oatmeal. I want to stay away from poultry and potatoes for him. Any advise would be greatly appreciated.
