Hill's Prescription Diet c/d Multicare Urinary Care is a dry dog food for dogs prone to struvite or calcium oxalate bladder stones. Clinically formulated to dissolve existing struvite stones in days and reduce the chance of new stones forming, it's a long-term feeding solution for dogs managing chronic urinary issues.

Controlled magnesium, calcium and phosphorus levels prevent crystal formation, while increased dietary moisture (from larger kibble that holds water) and balanced sodium encourage healthy urine flow. The recipe is enriched with potassium citrate and omega-3 fatty acids to support bladder health, and antioxidants protect the urinary tract from oxidative damage.

Vets prescribe c/d for dogs with a history of recurrent stones or crystals — once one episode happens, recurrence is common without dietary management. Owners stick with it because it works: many dogs go years between vet visits when the diet is fed consistently.
