Royal Canin Veterinary Diet Hypoallergenic is a dry dog food for dogs with food allergies or severe sensitivities. The hydrolysed protein is broken into fragments small enough to bypass the immune system, eliminating allergic responses to common dietary proteins.

Hydrolysed soy protein provides complete amino acid nutrition without the molecular size that triggers food allergy reactions. The formula deliberately excludes whole protein sources, uses a single starch (rice) and includes added fatty acids to support skin barrier health in dogs with allergy-driven dermatitis. Suitable for both elimination diet diagnostics and long-term feeding of confirmed food-allergic dogs.

Vets use Hypoallergenic for the standard food allergy diagnostic protocol — strict feeding for 8-12 weeks identifies whether food is driving symptoms. Many dogs stay on the diet long-term: ear infections clear, paw chewing stops and the coat improves visibly.
