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.




A calcium intake adapted to the animal's size and physiological condition prevents diseases caused by nutritional deficiency (osteofibrosis) or excess (anarchistic calcification). The growth and suckling periods require a high calcium intake.

A little background information

Calcium is a major mineral element, an alkalineearth metal known in nutrition as a mineral macro element because of the large amounts needed by the body. Calcium (Ca) and phosphorus (P) intake ratios must be perfectly balanced in the food. The ratio is 1 to 2.

Its role in the body

Calcium plays two fundamental roles in the body. 99% of the body’s calcium is retained in the bones, where it is responsible for making the skeleton solid together with phosphorus. Together they form the ‘cement’ of the bone. It also allows the transfer of information between the cells and the transmission of sensory impulses. If the calcium level in its food is very high young puppy is unable to adapt to the excess, continuing to passively absorb at least 30- 40% of the calcium ingested, which brings a risk of abnormal skeleton development.

Natural sources

Calcium is found in the bones of mammals in the form of mineral salts, as well as in the mineral sources such as calcium carbonate (chalk) and calcium phosphates.
