Hill's describes it as "clinical nutrition specially formulated to support dogs with food sensitivities." It is a dry kibble formulated for adult dogs, and the first five ingredients on the label are Corn Starch, Hydrolyzed Chicken Liver, Hydrolyzed Chicken, Ground Pecan Shells, and Powdered Cellulose. Hill's lists ingredients by pre-cooking weight, so the order shows what goes into the recipe before processing, not the finished proportions. It comes in 7 lb. Hill's product page states: "Ask your veterinarian for specific feeding instructions for your pet. Have your veterinarian monitor your pet's condition." Dogs who lose interest in a rotation often take it again with a single ingredient freeze dried topper crumbled over the top. Ask your veterinarian before feeding any therapeutic diet.
