    Chronic kidney disease + degenerative joint disease (DJD)


    Not Recommended For:

    • Growing puppies, pregnant or nursing dogs.
    • Patients with hyperlipidemia, pancreatitis, history of pancreatitis or at risk of pancreatitis.

    Evidence-Based Clinical Nutrition:


    • Feeding Prescription Diet® k/d® Canine significantly prolonged the time before occurrence of uremia in dogs with CKD. Only 33% of dogs with CKD in the renal food group fed k/d® Canine developed uremic crises after 24 months, compared with 65% of dogs in the maintenance food (control) group. 7
    • Dogs with CKD lived significantly longer when fed k/d® Canine. The median survival time following assignment to the k/d® Canine group was 594 days, while the median survival time for dogs after assignment to the maintenance food (control) group was 188 days. 7
    • Based on owner assessments using a content-validated questionnaire, dogs with CKD fed k/d® Canine for 24 months maintained good health-related quality of life while quality of life declined in dogs with CKD fed a maintenance (control) food. 8


    Prescription Diet® k/d®+Mobility Canine has the nutritional attributes of Prescription Diet® j/d® as a compliment to the attributes of k/d®

    • At the conclusion of the 90-day feeding trial, 82% of dogs with degenerative joint disease fed Prescription Diet® j/d® Canine showed increased weight-bearing ability as assessed by mean peak vertical force. 6
    • Based on clinical orthopedic examinations, a significantly greater percent of dogs fed j/d® Canine exhibited reduction in pain when affected joints were palpated compared with dogs fed a maintenance food. 6
    • Significantly greater reductions in NSAID dosages were possible in dogs fed j/d® Canine compared with dogs fed the maintenance control food. 9
    • The non-steroidal anti-inflammatory (NSAID) mean dosage was found to be 25% lower in dogs fed j/d® Canine compared with dogs fed a maintenance control food with lower concentrations of omega-3 fatty acids. 9
    • Dogs fed j/d® Canine had significantly higher concentrations of total omega-3 fatty acids and significantly lower concentrations of arachidonic acid at weeks 6, 12 and 24 than did dogs fed the maintenance control food. 10
    • Dogs fed j/d® Canine had significantly improved ability to rise from a resting position and play at 6 weeks and improvements in walking at 12 and 24 weeks as assessed by owners compared with the dogs fed the maintenance control food. 10


    Additional Info:

    • Chronic kidney disease (CKD) is a major cause of morbidity and mortality in dogs and cats.1 Nutritional management has been the cornerstone of long-term treatment of this condition for many years and has been shown to significantly increase both quality of life and survival in dogs with CKD. There is strong evidence behind nutritional management of canine and feline CKD with Hill’s® Prescription Diet® k/d®.2,3  
    • It is common for senior dogs to develop other age-related conditions such as reduced mobility or cognitive decline which can significantly impact the quality of life of both the dog and the pet parent.
    • Epidemiological studies have shown that 20% of dogs over the age of 1 year and 80% of dogs greater than 8 years of age suffer from degenerative joint disease (DJD), and prevalence increases with age.4 While DJD impacts the quality of life in geriatric dogs, nutritional management with omega-3 fatty acids has proved effective in managing this common condition.5 Omega-3 fatty acids provide clinical benefit to dogs suffering from DJD by helping to control inflammation and by reducing the expression and activity of cartilage proteoglycan degrading enzymes. Nutritional management of canine DJD with Prescription Diet® j/d® has been proven to be effective at both reducing clinical signs and improving weight-bearing ability in these patients.
    • Chronic kidney disease, DJD, and cognitive decline are some of the most common conditions impacting the lives of our aging canine companions. Nutrition can play a key role in managing these age-related conditions. That is why Hill’s nutritionists and veterinarians developed new Prescription Diet® k/d®+Mobility for dogs. This clinical nutrition not only supports kidney function but also helps to improve mobility and increase alertness and vitality.
    • k/d®+Mobility combines the nutrition of k/d® with the technology and efficacy of Prescription Diet® j/d®.
    • S+OXSHIELDTM: Formulated to promote a urinary environment that reduces the risk of developing struvite & calcium oxalate crystals
