Royal Canin Canine Urinary S/O effectively dissolves struvite uroliths. In addition, an acidic urinary pH is unfavourable to the development of bacteria, which are frequently associated with struvite uroliths.
Diluting urine decreases the urinary concentration of struvite and calcium oxalate crystals. Greater urinary volumes also ensures regular bladder wash-out.
Undersaturated urine is an environment where crystals cannot proliferate. Thus the urine is unfavourable to the development of struvite and calcium oxalate crystals.
Magnesium is a component of struvite (magnesium ammonium phosphate uroliths).


  • Struvite dissolution - Helps dissolve all types of struvite stones.
  • Urine dilution - Urine dilution makes the urine less liable to form struvite and calcium oxalate stones.
  • Low RRS - Helps lower the concentration of ions contributing to crystal formation.

RECOMMENDED FOR CASES OF; Struvite uroliths: dissolution and management of recurrence, Calcium oxalate uroliths: management of recurrence, Bacterial cystitis: management of secondary struvite crystalluria (in association with adequate antibiotherapy).

NOT RECOMMENDED IN CASE OF; Chronic Kidney Disease (CKD), Heart disease (when sodium restriction is sought), Concurrent use of urine-acidifying medication, Growth, gestation/lactation.
