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. The key insight: it's the protein's SIZE and STRUCTURE that triggers recognition. 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.
Indicated for:
- Adverse food reactions (skin or GI manifestations)
- Elimination diet trials to identify dietary triggers
- Inflammatory bowel disease with suspected food component involvement
- Urate and cystine urolith prevention (dogs)
- Long-term management of confirmed food-sensitive pets
Available in: HP (standard), Hypo Moderate Calorie (weight-prone patients), Puppy (growing food-sensitive dogs), Small Breed formulations, wet loaf, and treats.
During an elimination trial: This must be the ONLY food and treat consumed. Any dietary deviation — even small amounts of other foods — invalidates the trial. Commit fully for 8–12 weeks for conclusive results.
