umm...I know that my dad has a dog that is allergic to almost every kind of dog food there is and he itches all the time poor thing, he can't eat wheat,corn, I am not even sure what all but they had to do a special blood test on the dog to know and I know that they have to give him a bath every other day with special shampoo and he also has to get a steroid shot every now and then. Hopeful someone will come along to help you out, sorry I am not much help. But I wish you luck.
