Food sensitivities and intolerance are potentially serious problems that can result in irritated skin, coat and ear conditions or even gastrointestinal upset. Dogs that have a food sensitivity or intolerance, also called adverse reactions to food, typically experience an abnormal response to the protein in the food. If your dog suffers from adverse reaction to food, it is even more important to feed the right food. Hill's nutritionists and veterinarians developed Prescription Diet® z/d® clinical nutrition especially formulated to support your dog's skin and food sensitivities. In fact, z/d is clinically proven nutrition to help avoid adverse reactions to food. -Visible improvement in skin & coat in 30 days -Clinically proven to help normalize stool -Promotes healthy skin barrier -Helps support a healthy immune system INGREDIENTS: Corn Starch, Hydrolyzed Chicken Liver, Hydrolyzed Chicken, Powdered Cellulose, Soybean Oil, Calcium Carbonate, Dicalcium Phosphate, Lactic Acid, Potassium Chloride, Glyceryl Monostearate, Choline Chloride, Iodized Salt, vitamins (Vitamin E Supplement, L-Ascorbyl-2-Polyphosphate (source of Vitamin C), Niacin Supplement, Thiamine Mononitrate, Vitamin A Supplement, Calcium Pantothenate, Biotin, Vitamin B12 Supplement, Pyridoxine Hydrochloride, Riboflavin Supplement, Folic Acid, Vitamin D3 Supplement), DL-Methionine, Magnesium Oxide, minerals (Ferrous Sulfate, Zinc Oxide, Copper Sulfate, Manganous Oxide, Calcium Iodate, Sodium Selenite), Taurine, Mixed Tocopherols for freshness, Natural Flavors, Beta-Carotene.
