Hill's Prescription Diet z/d dog food is a complete dietary food for reducing intolerances to certain ingredients and nutrients in adult dogs. This food contains a selected source of carbohydrates and a source of hydrolyzed protein.

Food sensitivities and intolerances are potentially serious problems, which can result in skin irritation, hair and ear problems or even gastrointestinal problems. Dogs that have a food sensitivity or intolerance, also called adverse food reactions, often have an abnormal response to the protein in the food. If your dog has an adverse food reaction, it is even more important to provide the right food.

Hill's nutritionists and veterinarians developed Hill's Prescription Diet z/d, clinical nutrition specially formulated to reduce skin and digestive signs of food intolerances. In fact, Prescription Diet z/d is clinically proven nutrition that helps prevent adverse food reactions. This dry food has an irresistible flavor that your dog will love.
