Product Reviews
Royal Canin Veterinary Diet ® Canine Mobility Support JS ® dry dog food is rated 4.9 out of 5 by 66.
Rated 5 out of 5 by from It really helps! I started feeding Royal Canin Mobility Large breed around 9 month ago to my German Shepherd femal Nala who was diagnosed with Hip problems. My Vet told me about the diet and told me that I have to feed it for 3 month before I would notice a difference but I have noticed her to start to be more playful after around 6 weeks. Now she does take any more pain medication and she goes on daily walks again and enjoys playing with her brothers. The diet has made her coat look amazing too she is super shiny. I will continue to feed a high quality diet because my dogs are my children. Thank you Royal Canin for developing an amazing product.

Rated 5 out of 5 by from A Miracle!! My old boy, a German Shepherd mix, was beginning to have hip dysplasia issues. Bad ones; he could barely stand without pain, when an acquaintance recommended this food. After just one week, my best pal was up and around, tail wagging, and happy again! He's slowly regaining some mobility and acts like he's ready for our outings again! I'm not exaggerating when I say that this food has given him happy days back, and has given me more quality time with my friend that has been by my side through a lot of hard times. If not for this food, I'm not sure how much longer I'd have with him.

Rated 5 out of 5 by from Joint Mobility & Quality Of Life My Corgi is 10 years old & has arthritis from 2 torn ACL's. I bought him a doggie wheelchair to help with his recovery period. After a couple of weeks, he was up and going without any problems for about a year then he started showing signs of arthritic changes in his joints and wasn't as active as he used to be. I started him on the RC Joint Mobility Diet on 9-27-17. Within 1 week I noticed a change as he was eager to go for his morning walk without any stiffness. It has been almost 1 month now on this diet and my dog has full range of motion in his hips and joints! He is active and wants to play with me when I come home from work...This food has definitely given him his quality of life back..I highly recommend it to anyone who has a dog with joint issues.

Rated 5 out of 5 by from My dog is a puppy again! My Welsh terrier is approaching 9 years old and I wanted to try and give her support as she ages. I have been feeding her this product for about 3 month and can see the change in her mobility. So happy I purchased it. Good food with supplements is so important when feeding your dog. Thanks Royal Canin

Rated 5 out of 5 by from Best food available for my dachshunds. Using Mobility Support JS for my dachshunds not only gives them glucosamine and chondroitin needed for healthy joints and ligaments but their coats are even and shiny.

Rated 5 out of 5 by from Best food available Had been using iam's prescription Rx food with some success. My service dog is 12. Vet recommended this food and I changed. It literally has turned back the age clock. She now runs at the dog park and has much more stamina. It is worth every penny, PS angel has arthritis in her hips. So glad i changed !! I have had dogs my entire life and have never seen this effect before. Retired RN. PS wish they had a product like this for humans.

Rated 5 out of 5 by from great results My 10 year old pit has been on this food for the past 7 months. The taste must be good because usually it takes her a while to switch foods, exspecially if she does not like it, but she liked it from the first day and still does. Previously I noticed stiffness in the joints and she started to seem less interesteded in playing or anything that involved her to move. Since withing the past 5-6 months I have noticed her being less painful and moving around more. Occasionally she still has the joint pain but it is less severe than previously.

Rated 4 out of 5 by from Good food, poor packaging All 3 of my dogs eat this food and I love how it makes their coast shiny while keeping my pug with luxating patellas from limping! I really dislike how small the bags are and want a larger size. I'm a veterinarian and this is a common complaint about ALL RC food. They can't get the food just anywhere when its a prescription diet so it becomes an added inconvenience.
