Pro Plan Veterinary Diets Canine HA Hydrolyzed Dry Dog Food

Overview

Pro Plan Veterinary Diets Canine HA Hydrolyzed is a specialised veterinary diet formulated for the diagnosis and nutritional management of food allergies and intolerances in dogs. This highly digestible hypoallergenic formula contains hydrolysed protein that has been broken down into very small components, making it far less likely to trigger adverse food reactions.

Commonly recommended by veterinarians across New Zealand, HA Hydrolyzed is used during elimination diet trials and for long-term management of dogs suffering from chronic skin or gastrointestinal sensitivities. The carefully selected low-allergen ingredients help reduce digestive stress while supporting skin health and overall wellbeing.

Key Features & Benefits

Ideal for Food Elimination Trials

Highly Digestible Formula
Supports optimal nutrient absorption in dogs with compromised digestion or chronic gastrointestinal disease.

Supports Skin & Coat Health
Includes omega-3 fatty acids and essential nutrients that help maintain skin barrier function and reduce inflammation linked to allergies.
