Itching. Recurring skin infections. Chronic ear inflammation. Ongoing vomiting or diarrhea despite medication. If your pet is caught in this cycle, a food allergy or intolerance may be driving it — and Royal Canin Veterinary Diet Hydrolyzed Protein is the vet's most trusted tool to find out, and to manage it long-term.
How hydrolysis breaks the allergy cycle: Food allergies occur when the immune system misidentifies dietary proteins as threats. Hydrolysis breaks proteins into fragments so small the immune system can't identify them as the allergen — allowing proper nutrition without triggering the immune response.
Available in: HP (standard), Hypo Moderate Calorie, Puppy, Small Breed, wet loaf, and treats. During an elimination trial, this must be the ONLY food and treat consumed for 8–12 weeks.
