The ethos of the Royal Canin brand is based on its unique vision of the dog and the cat: The conviction that dogs and cats are not human beings but animals, and as a result true respect obliges us to treat them as such. True respect implies certain obligations, one of which is the pursuit of knowledge. To truly know the animal and understand its specific physiological and nutritional requirements, and--in consequence--guarantee it a "tailor made" food in line with its real nutritional needs. Royal Canin's philosophy is therefore deliberately non-anthropomorphic. In the field of canine and feline nutrition, some manufacturers put the owners first and use them as the basis of all innovation. At Royal Canin, we put the dog and the cat at the heart of our research process; this is a radically different approach.
