What is a lofty competence allergen dog food?

I have a lab that has terrible allergies and is on a vet prescribed food right presently. I was wondering if there are any alternatives to it. I surmise that it is Royal Canine Skin Solutions that she has right now.

I also have a dog with severe allergies. I've tried many foods and finally found a moral brand by Hills Diet, called ZD Ultra. It's made from duck and potato, which are low allergen foods. It's the only food that did not cause my dog to break out. The prime thing you need to look for in finding a dignified quality food is to make sure it does not contain corn or wheat flour or beef, which alot of dogs are allegic to, and instead look for foods that contain potato, duck, or chicken.
Hope I help.
