Royal Canin Canine Urinary S/O Moderate Calorie is a dietetic dry kibble specifically developed for adult dogs prone to overweight and suffering from urinary tract issues. This formula aids in dissolving struvite stones and crystals, helps prevent the recurrence of urinary stones (both struvite and calcium oxalate), and supports the management of bacterial bladder infections. The adapted energy content assists in maintaining a healthy weight, particularly for overweight dogs. Key benefits include struvite stone dissolution, moderate calorie content for weight management, urine dilution to prevent stone formation, and a low Relative Saturation (RSS) value to reduce crystal-forming ions. It's recommended for dissolving struvite crystals/stones, managing recurrent struvite and calcium oxalate stones, and treating bacterial cystitis in conjunction with antibiotics. It is not recommended for dogs with chronic kidney disease, heart disease requiring sodium restriction, those on urine-acidifying medication, or during growth, gestation, and lactation. The kibble is formulated to increase urine volume and lower urine RSS, creating an environment less conducive to crystal formation. Duration of treatment typically ranges from 5 to 12 weeks, or until crystals dissolve, with continued feeding of an S/O index food recommended post-recovery to prevent re-infection.
