Notes and quick guidance

• “Hypoallergenic” is used by manufacturers in different ways. The gold‑standard for true elimination/hypoallergenic diets in dogs is a veterinary hydrolysed or novel‑protein prescription diet (e.g., Royal Canin Hypoallergenic, Hill’s z/d, Purina HA). Those are specifically formulated for elimination trials and management of confirmed food allergy and typically require vet guidance. (royalcanin.com)
• Over‑the‑counter brands (grain‑free, single‑protein or limited‑ingredient diets) such as Ivory Coat, Black Hawk, Advance, James Wellbeloved can help with food sensitivities or intolerances and may reduce exposure to common triggers, but they are not the same as veterinary hydrolysed prescription diets. If you suspect a true food allergy, consult your veterinarian before starting an elimination trial. (petbarn.com.au)
