8 year old like a puppy again

My 8.5yr old bloodhound has had joint and back problems on and off for the last few years. I've done cold laser therapy, acupuncture, supplements, and another brand of mobility food as well as considered surgery b/c he was in so much pain he couldn't be a normal dog. Once I learned about the green lipped muscles in the Royal Canin Mobility Support JS I decided to try it out and I am so glad I. I no longer give him any supplements, he can jump on and off furniture and into and out of the car with no problems. He can play and run and be a happy dog again and the future looks very happy for him! I have recommended this diet to many people and those who have switched have all had great experience with it as well.

Amazing product that saved my dog!!!

I bought this product after my dog tore his cruciate ligament after many failed tries with different food brands claiming to ease and help his mobility. Within a week of moving him onto this I noticed a massive difference! He could move so much easier and less discomfort, he seemed so much happier and the longer he stayed on it, the more he improved! When he had his accident I honestly thought this was it for him, but thanks to this food, I am now able to take him for walks again! Cannot recommenced this enough! Totally worth the money! I’ve got my dog back!!

It Works!

I have an irish wolfhound that was diagnosed with HOD as a puppy. As a result, his body is burdened with pain as his front legs don't work as they should. Ever since I started feeding this food, he is happier, more comfortable, and more active.
