Hill's Prescription Diet u/d Urinary Care is a veterinary-grade wet food for adult dogs, formulated specifically to reduce the risk of urate and cystine bladder stone formation.

The diet works by controlling the minerals that contribute to crystal and stone development — particularly purines, which drive urate urolithiasis. Protein is deliberately restricted and carefully sourced to minimise uric acid production. Developed by Hill's nutritionists and veterinarians, u/d requires a veterinary prescription and is intended for dogs diagnosed with urate or cystine urolithiasis or at elevated risk.

For dogs with a confirmed diagnosis of urate or cystine stones, u/d offers a clinically backed dietary management option. Available in 370g cans, it's typically used as part of a long-term management plan under veterinary supervision.
