Product Reviews
Royal Canin Veterinary Diet ® Canine Mobility Support JS ® Large Breed dry dog food is rated 4.9 out of 5 by 40.
Rated 5 out of 5 by from Best mobility food! I have had my Great Dane and my Tibetan mastiff on the mobility large breed for about 6 months and I have to say I am so pleased. Before they were on purina and then never seemed to want to eat it. From day 1 they've loved the mobility. I think it is the large pieces of food. Now they didn't magically become puppies overnight, but I have noticed they get up faster and seem less stiff. I would recommend this food to anyone will a larger dog.

Rated 5 out of 5 by from Best brand of dog food on the market! I swear by Royal Canin! Hands down the best food I've ever feed to my two dogs and cat. My dogs are on the mobility diet and it shows! They were on JD by another brand and I definitely didn't see the improvements I've seen with the Mobility. Not to mention my dogs LOVE the food! They devour it when I put it in their bowls. Royal Canin has the best palatability I've ever seen for both dogs & cats. I wouldn't feed my animals anything else!

Rated 5 out of 5 by from My Boxers love the Boxer Formula I started our Boxers on the Boxer Formula from Royal Canin a couple of months ago. We are so happy with the energy that it gives our dogs. Their coats are beautiful and shiny and their skin is so healthy. Our Vet says they are the best looking Boxers he has ever seen. I won't feed them anything else. We have now started to use the treats and our babies love them! This is a great dog food!!

Rated 5 out of 5 by from Good stuff My 13 year old Border Collie has been on Royal Canin food for most of his life. Four years ago I switched him from Royal Canin Calorie Control to the Royal Canin Mobility Support. It was an easy transition and he loves the food. The Mobility Support food along with a quarterly Cartrophen shot have made world of difference to my fellow. So glad that this option was available!

Rated 5 out of 5 by from Veterinary Surgeon Recommended My two year old dog is cruciate disease - one knee surgery down, and one to go. My surgeon strongly recommended this food in order to obtain a very high dose of fish oil that my dog's joints would appreciate. My previous geriatric dog also benefited from this food as well.

Rated 5 out of 5 by from Highly recommended I work at a vet clinic and recently started carrying Royal Canin. I decided to try a bag of the mobility support for my boxer and she seems to be doing very well on it! She loves the taste and I am satisfied knowing she is getting the best ingredients possible!

Rated 5 out of 5 by from great joint support food This food works well for any dogs with orthopedic issues. The big sized kibble are also nice when you have dogs that eat too quickly, as it helps slow them down. This prescription food works better then the other prescription joint foods, in my opinion.

Rated 5 out of 5 by from Keeps my pup going! We started buying this food for my dog because it was prescribed by our vet and we are so thankful! It helps our Old English Sheepdog stay healthy after being diagnosed with hip dysplasia and undergoing two surgeries! He loves it and so do we!

Rated 5 out of 5 by from Helps keep our girl active Our lab/shepherd mix loves this food. It is nice not adding in a joint supplement and fish oil supplement every day because what she needs is already in the food. She is an active young gal and keeps her moving.

Rated 5 out of 5 by from Excellent! I have used this food for years. I have labs and am always concerned about their joints so I start them on this food early because it meets their nutritional needs and helps prevent joint issues.

Rated 5 out of 5 by from Great for our Labrador My Labrador was very satisfied with the taste and he seems like a puppy lately ~ we switched to the bread specific variety and it's made a difference in his coat, weight & abilities.
