The Puppy and the Dog They have been man’s companion through the ages and adapted to their owners, but they have their own behavioural and nutritional demands. Knowing and respectingthem will guarantee their health and well-being.

The cat’s feline nature is always a matter of fascination.He adapts with apparent ease to daily life, and yet he has behavioural and nutritional requirements of his own. Knowing them and respecting them will guarantee his well-being and his health.

Because of its composition, a Royal Canin Health Nutrition food provides all essential nutrients measured out with utmost precision in order to contribute every day and on a long-term basis to the well-being and health of every animal, according to his age, his size, his physiological condition and his breed.

Innovation for the sake of dogs and cats’ health. For over 40 years, Royal Canin has worked with breeder partners and veterinary nutritionists to go ever further into innovation and precision to enable us to formulate nutritional solutions which perfectly meet dogs and cats’ real needs.



Physiologically speaking, carnitine helps turn fats into fuel for the cells. It is consequently very useful and effective during physical effort, especially when it is sustained. In some dog breeds (Boxers, Dobermans, Cocker Spaniels, etc), a serious heart disease is often related to a deficient production of carnitine by the body.Weight loss can be accelerated in obese animals by adding carnitine to the food.

A little background information

Carnitine is a non-essential amino acid normally made by the body from two other amino acids, lysine and methionine. It becomes essential in food only when the body is unable to synthesise enough of it to cover its needs. Its chemical structure allows two forms of the molecule, D and L. Only L-carnitine is active and effective.

Its role in the body

Energy is mainly produced in dogs and cats through the oxidation of fat in the mitochondria, which are tiny power generating plants in the cells. The role of carnitine is to shuttle fatty acids through the membrane around each mitochondria. Carnitine also has an important role to play in reproduction. In some species, carnitine supplementation during gestation and lactation increases the weight of newborns and the number of animals in a litter.

Natural sources

Besides synthesis in the liver, food is another source of supply. While plants contain negligible quantities of carnitine, fresh meat is a rich source, mutton and lamb in particular.
