c/d Multicare + Metabolic Weight Dry Dog Food

Overview
Hill's Prescription Diet c/d Multicare + Metabolic Weight Dry Dog Food is a combined clinical diet formulated for dogs that need urinary health support alongside weight management. Overweight dogs are at increased risk of developing urinary conditions, and managing both simultaneously with a single diet removes the complexity of balancing conflicting nutritional needs. This formula helps create a urinary environment that reduces crystal formation while also supporting healthy, sustainable weight loss.
Formulated by Hill's nutritionists and veterinarians, it controls key minerals associated with urinary crystals while activating the dog's natural metabolism to encourage fat reduction and preserve lean muscle. It is a practical solution for dogs dealing with more than one health challenge at a time. Always consult your veterinarian before starting your dog on this diet.
Nutritional Analysis
