Product Reviews
Royal Canin Veterinary Diet ® Canine Mobility Support JS ® Large Breed dry dog food is rated 4.9 out of 5 by 64.
Rated 5 out of 5 by from no nsaids!! I've been feeding my 14 yr old lab mix this food for about 3 yrs now. Before starting the mobility diet, he was painful whenever we would take long walks. Now after being on this incredible food he can hike for 8 hrs and doesn't need any prescription drugs. I tell all of my clients who are nervous about starting nsaids in their stiff seniors to try this food first. I am not knocking the value of a good pain med for an arthritic dog but if I can give my dog a new lease on life without any side affects (nsaids can affect liver function long term), I'm all for it!

Rated 5 out of 5 by from Definition of Healthy My German Shepherd Mix Dog, Cheko, was moving more slowly to the point where he wouldn’t want to get up to greet me even though I know he wanted to. I was giving him joint supplements and it seemed to help a bit, but he’d limp after laying for a while. After a diagnosis of hip dysplasia and diet recommendation from the vet, I began giving him this diet. Boy is my boy ever a pup again! He greets me and I can rest easy knowing he’s getting the proper nutrition for his condition and as a dog. Also, love the fact that it’s easy on the stomach. His coat looks beautiful, he’s healthy, and his mobility has never been better!

Rated 5 out of 5 by from Great food that does what's promised I started using this food about 18 months ago for my old arthritic dog. He had an old wrist injury that caused arthritis in his wrist and elbow, and he was taking pain medication and joint supplements. After switching him to Royal Canin's Mobility Support I was able to stop using the joint supplement and cut back on the pain medication. Sadly, he passed away a few months ago, but I will continue to feed my other dog Mobility Support because of all the great benefits it offers.

Rated 5 out of 5 by from I love Mobility This food really is a miracle food. I do a lot of rescue work ands it’s amazing seeing how this food helps transform my senior fosters. Their mobility truly improves, but it also improves their coat and makes it super shiny. As an added bonus it helps cut down on shedding. I like this food so much It is my first choice for my dogs and my fosters. It’s worth paying a little more for this food because of the overall health benefits and you will save money by not having to buy as many additional supplements for their joints or coat.

Rated 5 out of 5 by from Great Results! I got a sample bag of this food for my baby Marley and she has done SO well on it. She has a history of a broken limb so she is on Dasuquin as well as Omega 3 Fatty Acids. This food offers both and she seems much more comfortable in her weak joint. Love this food, LOVE this brand!

Rated 5 out of 5 by from Great food for Senior Labrador Retriever! Our Lab is almost 11 years old and as far late he sort of “lost his spring” during his daily walks.... we discussed this with his Vet and she said it may be time to switch him from his regular Royal Canin Labrador Retriever food to this food.... and about 4 weeks on this food, his “spring” has returned. Remarkable how much better he goes up and down the stairs... we have bought our second large bag, and will keep him on this food. And Yes, he LOVES the food, but he loved his breed specific food as well.

Rated 5 out of 5 by from Just the right ingredients for my 225 lb Mastiff Our OE Mastiff puppy has been struggling somewhat w/ his hips and while I LOVED Royal Canin's Giant Breed charcoal briquette sized kibbles (no longer made) - this is just as good if not better, thanks to the added joint enhancing ingredients!

Rated 5 out of 5 by from Dog loves it He seems to love this food, but he is a lab so I don't know how much that means, but thgere is never any left over and he returns to lick his (stainless steel) bowl several times, just in case.
