Purina Pro Plan Veterinary Diets Canine HA Hypoallergenic Dry Dog Food, and it is indeed available in a 3kg size . This is a veterinary diet, so it's important to use it under the guidance of a vet.

Here is the comprehensive information for the 3kg bag.

Product Overview

Purina Pro Plan Veterinary Diets Canine HA Hypoallergenic is a complete dietetic dry food for the diagnosis and long-term management of food allergies and intolerances in puppies (from 4 months old) and adult dogs . It is specially formulated for an elimination diet trial, which is the most reliable method for diagnosing food allergies .

The recipe is truly hypoallergenic, featuring a single hydrolysed protein source. This means the protein has been broken down into fragments so tiny that they are highly unlikely to be recognized by the immune system, thus preventing an allergic response .

Key Features and Benefits

Single Hydrolysed Protein Source: Contains hydrolysed soya protein with a low molecular weight to help avoid allergic reactions .
Purified Carbohydrate Sources: Uses purified carbohydrates like corn starch to further minimise the risk of an allergic response .
Omega-3 Fatty Acids: Enriched with omega-3 fatty acids to help support the body's natural anti-inflammatory processes .
Supports Compromised GI Function: Highly digestible formula with a lipid energy source (Medium Chain Fatty Acids from coconut oil) that is easier for dogs with gastrointestinal issues to digest and absorb .
Skin Health: Enhanced levels of zinc, omega-3 and -6 fatty acids, and vitamin A to help maintain the integrity of the skin barrier .
