I have been feeding Zignature for the last few years and LOVE it!! Looking on their website, it should meet your needs. And a lot of stores that carry it have samples you can try. Here is what they say about their product:
Physiologically Tuned™, limited ingredient premium food for dogs. Hypo-allergenic meat first recipe, with no Corn, Wheat, Soy, Dairy or Chicken, Chicken Eggs or Chicken By-Products
You can order online if there isn't a store close to you. I know Gail, who shows Aussies in NADAC, at Tin Woof Inn sells it and has samples in their store.
