Hill's Prescription Diet u/d Urinary Care Original Dog Food was developed to aid in the management of dogs with the problems associated with urolithiasis or for dogs with advanced kidney disease. It helps reduce the formation of oxalate, urate and cystine stones and contains a low level of high-quality protein to reduce the formation of breakdown products that cause discomfort in patients with kidney failure, with reduced salt to help control fluid retention in early heart disease. 

The right balance of minerals in food is essential for bladder health, and reduces the risk of crystals or stones forming in the urine. Hill's Prescription diet u/d Urinary Care has reduced levels of the building blocks for urate and cystine stones, decreasing the risk they will form again. It is also supplemented with antioxidants that support a healthy immune system.
