I'm glad you got him off puppy chow, because it is crap food. Blue Freedom isn't too bad. I would change proteins. See if the food has chicken in it, as a lot of bullies are allergic to chicken, plus companies like blue will change the source of where they get there proteins from. If you try a different protein and you still have problems, try a better food like FROMM 4 Star "Game Bird" ours do great on it. The MalAcetic wipes are usually pretty good to use when they have a problem. You can also use unscented baby wipes too.
