I had my dog tested because his whole body was covered in hot spots and he was going bald. Turns out he is allergic to just about everything in every dog food plus many environmental allergies. I had him on Purina salmon and rice for a while but switched to homemade raw a few years ago and it has been amazing for him. It's not cheap or easy, but I highly recommend it for any dog with allergies (Dr. Becker's homemade raw book is my guide but I do take some short cuts). My point in responding though is maybe look into whether the salmon and rice food has any of the same ingredients you are currently feeding him. I think i was getting it at PetSmart.
