At Royal Canin, we believe the secret to providing cats and dogs with the best nutrition lies not in any passing fad, but in well-researched scientific fact. That’s why we always use a purely scientific approach to create diets designed to cater to the specific needs of pets of all shapes, sizes, ages, lifestyles and breeds.

From the time they’re born until they’re well into their golden years, dogs’ nutritional needs are constantly changing, and we believe their food should, too. That’s why we offer a full line of products designed for dogs at every life stage. 

From the time they’re kittens until they’re mature, cats’ nutritional needs are constantly changing, and we believe their food should, too. Your cat’s health matters, and that’s why we offer a full line of nutrition designed for every life stage. 

ROYAL CANIN® PROFESSIONAL products are specifically formulated to meet the needs of the breeding kennel and cattery.  Our innovative science-based solutions are the result of our 40-year collaboration and partnership with breeders across the globe.
