z/d Hydrolysed Chicken Flavour Dry Dog Food

Overview

Hill's Prescription Diet z/d Hydrolysed Chicken Flavour Dry Dog Food is a hypoallergenic dry diet formulated for dogs suffering from food allergies, adverse food reactions, or skin and gastrointestinal conditions driven by dietary intolerances. Food-related allergies in dogs can develop over time — even to proteins they have previously tolerated — and often manifest as itchy skin, recurrent ear infections, vomiting, or chronic loose stools. This formula uses hydrolysed chicken protein, broken down to a molecular level that bypasses the immune system's normal response, making it an effective option for highly sensitive dogs.

Formulated by Hill's nutritionists and veterinarians, it delivers complete and balanced daily nutrition and is designed to be fed as a sole diet. It is commonly used for both diagnostic food trials and long-term allergy management. Always consult your veterinarian before starting this diet.
