Hill's Prescription Diet j/d Joint Care is a veterinary dry food formulated for dogs with arthritis or joint conditions. Clinically proven to improve a dog's ability to walk, run and jump in as little as 21 days, it requires a veterinary recommendation and suits adult dogs of all breeds managing reduced mobility or ongoing joint discomfort.

The formula centres on therapeutic levels of omega-3 fatty acids to support joint function, combined with glucosamine and chondroitin sulphate to help preserve cartilage. Controlled calorie content and added L-carnitine support healthy body condition, reducing mechanical stress on affected joints. Clinically proven antioxidants counter oxidative damage. Developed by Hill's nutritionists and veterinarians, the chicken-flavoured kibble is manufactured in the USA using globally sourced ingredients.

Owners with arthritic dogs often turn to j/d because the results are measurable — clinical trials show meaningful mobility improvement in a matter of weeks. For dogs where movement was noticeably declining, it's frequently the diet that keeps them moving comfortably into old age.
