At Man’s side for millenia, the dog has adapted, but he has behavioral and nutritional requirements of his own. Knowing them and respecting them will guarantee his well-being and his health.

The cat’s feline nature is always a matter of fascination. He adapts with apparent ease to daily life, and yet he has behavioral 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.

Urinary S/O

URINARY S/O is a complete dietetic food for dogs formulated to dissolve struvite uroliths and reduce their recurrence through its urine acidifying properties, a low level of magnesium and a restricted level of high quality protein.

Feeding duration:

5 to 12 weeks of dietary treatment are required to dissolve uroliths. If a urinary tract infection is present, Urinary S/O Canine, combined with an antibacterial agent, should be prescribed for at least one month after a negative urine culture result is obtained

Increasing the volume of urine simultaneously reduces the saturation of urine with calcium oxalate and struvite. This approach ensures that Urinary Canine produces a urinary environment unfavourable to the development of both struvite and calcium oxalate crystals
