Hill's Prescription Diet c/d Multicare is a veterinary dry food for adult dogs prone to urinary issues, available on veterinary prescription. The recipe is formulated to manage both struvite and calcium oxalate crystals — the two most common urinary stone types in dogs — through controlled mineral content.

Calcium, phosphorus, and magnesium levels are controlled to reduce conditions that favour crystal formation. Hill's states the formula is clinically tested to help dissolve existing struvite stones and reduce recurrence risk for both stone types. Chicken provides the primary protein source, and the diet is formulated to be nutritionally complete for long-term feeding.

Dogs with a history of urinary stones, recurring UTIs, or struvite-prone bladder conditions are the primary candidates for this diet. The dual-crystal coverage means a single food handles both common stone types, simplifying long-term management for owners dealing with ongoing urinary health issues.
