My dog is very allergic to chicken, corn, peas and soybeans. I didn't realize that the majority of  "Chicken-Free" (high end!) foods still use chicken fat for flavor, or chicken by-products.  Les showed me that there are only a few dog foods that are truly free of both.  One of them is Exclusive Beef and Rice, or Salmon and Potato. It's like I have a different dog since I started her on Exclusive! Can't recommend Sheridan Seed enough. They KNOW what they sell!
