Royal Canin realise that one food doesn't suit all. They take into account age, activity, breed, size and lifestyle when creating Royal Canin diets, and they were the first to do so. In 1980 Royal Canin were the first to introduce specific diets for large breed puppies, in 1997 they were the first to meet the different nutritional needs of small, medium and large breeds of dogs, and in 1999 they launched the first food for specific breed of cat, formulated for the unique dietary needs of Persians. The Royal Canin Veterinary range includes clinical diets to assist in the nutritional management of certain conditions and life stage diets to help keep your cat or dog in the best of health.
