Hill's Prescription Diet c/d Multicare Urinary Care Dog Food
Hill's c/d Multicare is often chosen for its broad clinical evidence and proven track record in reducing recurrence of both struvite and calcium oxalate-related urinary problems, offering comprehensive long-term urinary health support. Compared with Royal Canin SO and Purina UR, c/d is marketed with extensive clinical studies and veterinary support materials, which can justify a slightly higher price for practices prioritizing scientific backing and patient outcomes. Its financial trade-off is higher per-bag cost in exchange for a robust prevention profile and formulations that promote increased water intake and urinary comfort.

Royal Canin Veterinary Diet Urinary SO + Hydrolyzed Protein Dog Food
Royal Canin Urinary SO + Hydrolyzed Protein combines the urinary stone management of the SO line with hydrolyzed proteins to address concurrent food sensitivities, offering a specialized solution for dogs that need both urinary care and an elimination-style diet. This dual-purpose technical advantage differentiates it from standard SO, Hill's c/d and Purina UR by reducing the need for a separate hypoallergenic prescription, though it may carry a premium price due to its specialized formulation. Clinically useful for patients with multi-factorial issues, it lets veterinarians simplify treatment while maintaining urinary control.

Hill's Prescription Diet u/d Urinary Care Dog Food
Hill's u/d is formulated specifically for rapid struvite stone dissolution and short-term management, with a low-mineral, urine-diluting approach that makes it a preferred acute-care prescription in veterinary settings. Unlike c/d which is aimed at long-term prevention, u/d is often recommended for active dissolution phases and can be more cost-effective for time-limited courses, though it requires veterinary monitoring during use. Its technical advantage is a focused dissolution formulation, giving clinicians a reliable option for resolving existing struvite stones before transitioning to maintenance diets.
