ROYAL CANIN® is recommended by Vets Our formulas have been developed in collaboration with vets, veterinary nutritionists and scientists to create high quality, science-backed food your puppy will love.
Vets recommend Royal Canin so highly because there is a veterinary nutritionist on staff who makes sure that the ingredients in the food are of high quality and the diet is nutritionally balanced to get the needs of the dog.
There's no single "number 1" healthiest dog food, as the best choice depends on your dog's age, breed, and health; however, look for foods meeting AAFCO standards (Association of American Feed Control Officials), with real meat as the first ingredient, and vet-recommended brands like Hill's Science Diet, Purina Pro Plan, and Royal Canin are often cited for balanced nutrition. Freshly prepared or raw diets can also be healthy but carry risks, so always consult your vet.
If your pet has breed-specific needs or unique habits, Royal Canin's tailored approach is a clear winner. For pet owners seeking high-quality, sustainable options without the complexity of breed-specific formulas, Hills Science Diet offers a straightforward, reliable choice.
While both brands offer commendable quality and have their strengths, Royal Canin tends to focus more on specific breed needs and has slightly fewer major recalls. Purina Pro Plan often emphasizes a meat-first approach, which many owners appreciate for protein content.
Vets most commonly recommend brands like Hill's Science Diet, Royal Canin, and Purina Pro Plan due to their extensive research, scientific backing, and availability of specialized prescription diets for specific health conditions. Other trusted options often mentioned include Eukanuba, Advance, and some Australian brands like Prime100, with specific formulas tailored for life stages, breed sizes, or health issues like skin sensitivities or weight management.

Royal Canin is involved in a significant class-action lawsuit, Royal Canin U.S.A., Inc. v. Wullschleger, concerning deceptive marketing of its "prescription" pet foods as medicinal when they allegedly contained no unique drugs, only premium ingredients, leading to inflated prices for pet owners. A key recent development was a January 2025 Supreme Court ruling clarifying that if a plaintiff removes federal claims from a case, the case must be sent back to state court, even if it was initially removed to federal court based on those federal claims. This case highlights ongoing consumer concerns about prescription pet food marketing and pricing.

Focus on avoiding poor-quality protein sources (unspecified meat meals), fillers, artificial additives, and dangerous human foods like chocolate, grapes, onions, and xylitol.
