My dog has terrible gas. He is a pit bull mix that is a little over a year old. We've had him for around 6 months. He eats a lamb and rice, hypoallergenic diet. When we first got him he was losing fur around his neck and shoulders and chewed his feet constantly. After switching to this dog food all of those symptoms cleared up and his hair has finally regrown. But he still has awful, horrible gas. I know people joke about this with their dogs, but yuck! I'm hesitant to switch his food to anything to else in case it starts the itching and hair loss again. Any suggestions?
