HA Hydrolyzed Dry Dog Food

HA Hydrolyzed Dry Dog Food

Pro Plan Veterinary Diet
4.4
(
29
)
Purina Pro Plan Veterinary Diets HA Hydrolyzed Dry Dog Food is an extruded dry kibble formulated for dogs with adverse food reactions, including confirmed or suspected food allergies and food intolerances. The formula uses hydrolysed soy protein isolate — protein enzymatically broken down into smaller peptide fragments — as the sole protein source, alongside corn starch as the single carbohydrate source. This limited, hydrolysed profile reduces the likelihood of an immune-mediated dietary response. The vegetarian formulation makes it appropriate for dogs with confirmed sensitivities across multiple animal protein sources. Coconut oil provides medium-chain triglycerides, and the formula includes antioxidants for immune support. It is suitable for all life stages and breed sizes. This diet is not appropriate as a general-purpose food for healthy dogs without a diagnosed food sensitivity. Speak with your veterinarian before introducing this food.
