Our team of clydesdales here are all on JF and we have seen such a huge improvement whilst riding and working them. They're more eager to trot and canter and one of our stallions is jumping at a height we've never seen before

My Alaskan Malamute has only been on the formula for approx 2 weeks im seeing a change in her already.

Saw K9JF at the easter show. This product has transformed my 15 year old staffy. His joint soreness is massively improved and I can saw that thus product has significantly improved his quality of life. He just enjoyed his 16th birthday with his daily walk. Thank you so much

Rosie is 9, and has been on Green Lip Mussel capsules since 12 months old, when she suffered a reaction to her C4 injection, that left her with a weakening in her legs. For a few weeks now, she has been having a dose of TUFF ROCK K9 JF With her daily meal, and we can definitely see a difference. Usually when she runs around, she suffers with a limp, or favours the sore side for some time, but lately, she seems to get over any soreness a lot quicker, and seems happier, somewhat stronger and fitter. We are more than happy with this product, and would recommend it for any dog suffering a weakness or arthritis, as this seems to help tremendously.

While I have a Hairless Chinese Crested & Mini Xoloitzcuintle (Mexican Hairless), who do agility, this keeps their joints beautiful & when the crested retires, he will still be kept on this for LIFE..

I first purchased K9JF from The Royal Easter Show in 2016. My dog and I found it to be an amazing product. Prior to using this product, my dog Thor, who is now 10.5yrs old, suffered debilitating bouts of arthritis. For days at a time he'd be out of action - unable to chase his beloved ball, jump onto the bed or climb the stairs. I couldn't even pat him because of arthritic pain in his neck! Since using K9JF he has regained the spring in his step. While the arthritis is of course still there, he has not had any pain from it and loves to chase the ball again. Thank you tuffrockk9.com!

My 7 year old Lab x somtimes pulls up stiff after her fun in the park with the tennis ball. I have noticed that this isn't as bad since having her on K9JF. Its only been a few weeks since i have been giving it to her so hopefully this will continue to improve. I also give it to my 2 year old Kelpie who always looked to have a 'flat' coat. Now her coat is extremely shiny.

Excellent product
