Product Reviews
Royal Canin Veterinary Diet ® Canine Mobility Support JS ® dry dog food is rated 4.9 out of 5 by 48.
Rated 5 out of 5 by from Seeing results already! I started our 6 year old Sheltie on this diet recently; she has struggled with osteoarthritis problems for several years, and although joint supplements help somewhat, it has been amazing for me to see how much more quickly and dramatically she has responded to the Mobility diet! In less than a month, she is moving around so much better, is much more active, and will even take off running like she used to from time to time, with seemingly no issues following. I hope to continue her on this diet indefinitely!

Rated 5 out of 5 by from My dogs (and cat) love it! This diet has been a blessing for my dogs. They are all 10+ yrs old. I adopted a senior Chihuahua in Dec 2012. He was suffers from severe spondylosis and was very picky with his food. His coat was thin and he was "crickety". After refusing the "Fresh Pet" he had eaten for 6 months, I finally decided to soak the Mobility dry that my other seniors were happily eating. He was ecstatic to have it and has yet to turn his nose up at it! His coat is lush and he looks forward to eating every day now! Thank you

Rated 5 out of 5 by from Best food for mobility My aging service dog with arthritic hips had been on another tx mobility food for years and I had seen some progress. Vet recommended this and it has taken years off her life. She now trots around the dog park. Wish I had known about this earlier!!

Rated 5 out of 5 by from My dog loves this! My dog was diagnosed with hip dysplasia and arthritis at a young age, and I couldn't be happier with this diet! It gives her the extra joint support she needs in addition to her regular medications she is on. She loves the taste of it.

Rated 5 out of 5 by from Great Product/Great Nutrition I am a veterinarian. I feed this product to all 4 of my dogs. I can see a noticeable difference in their comfort levels when using this product. All of my dogs are older and have arthritis issues. The high levels of the omega-3 fatty acids helps their coats and joints. I have also been able to reduce the use and/or dosage of medications that I use to control their joint pains. I will always feed this to my dogs and will recommend it to my patients.

Rated 5 out of 5 by from My dog loves it! My dog used to be on Hills joint food(J/D), it wasn't bad but I felt for the money RC has more to offer for the joint diet. With that being said, my dog loves to eat it and finishes it every time. She seems more spunky and definitly gets around easier. With her being 12 years old, I worry about her not getting around as well. Since she has spine and hip issues, its bound to happen but I do feel the RC mobility is worth it. Plus she is happy. :)

Rated 5 out of 5 by from Expensive but worth it!! I have a 10 1/2 yr old female black lab who had been my "mobility" service dog for the last 9 1/2 yrs. I noticed 1 day that her hips were bothering her so I took her to our Vet and I started her on this food immediately. She's been on it for over 2 yrs now and her hips have improved greatly. like I said, expensive but well worth the money!!

Rated 5 out of 5 by from Healthy Police K9 My vet put my police K9 on mobility support based on the hard work that he goes through on duty with tracking, apprehension and narcotics detection everyday. K9 Rocco is almost 7 years old and still runs circles like a puppy during down time and easily runs 2 mile tracks in an instant on duty.
