Clinically proven to help dissolve struvite uroliths in dogs.

How it helps:

For the nutritional management of dogs with urinary tract disease. Urinary tract disease in dogs is often caused by the formation of mineral-based crystals and stones in the urinary tract that can cause discomfort, bloody urine and even life-threatening obstruction. For dogs, struvite crystals generally cause urinary tract disease. Prescription Diet™ s/d™ has been formulated by veterinarians to help resolve struvite crystals and stones in your dog. Struvite forms as a result of urine that's saturated with protein, calcium, phosphorus and magnesium combined with an improper urine pH.
