Urethral problems are fairly common in dogs. Problems can include the ureters, bladder or urethra. One of the main causes of urinary tract problems is the formation of bladder stones. Bladder stones are formed by the formation of crystals in your dog's urine. Both the acidity of the urine and the composition of minerals affect the formation of the crystals. When your dog suffers from bladder stones, the vet will, in most cases, prescribe a special dietary food and/or medication.

Thanks to the special composition of Urinary S/O from Royal Canin, the effective dissolution of urinary crystals is made possible. Royal Canin has developed a method that allows the S/O Index of a food to be determined. The S/O Index is based on the acidity (pH) of urine, urine volume and the concentration of various components in urine that can form stones. Thanks to the low S/O Index, Royal Canin Urinary S/O can dissolve struvite stones and help reduce both struvite and calcium oxalate stone formation. In addition, increased fluid intake is created (with the help of slightly increased sodium content), increasing the amount of urine. This reduces the concentration of crystal-forming compounds in your dog's urine.
