    I swear by this product. Our 10yr old Labradors seem to be walking and running with a little more ease, when they have this daily.

    My dog is 13 years old and somewhat arthritic. This product helps her immensely, and keeps her as active as she can be. I highly recommend its use with aged dogs.

    K9JF is Amazing & Really Works

    Posted by Wendy & Nils on 2nd Jul 2019

    We have a beautiful GSD named Shadow that was given to us when she was about 4 years old in 2011. Over the years she had found it difficult to jump up onto her trampoline bed & also had an issue when playing with our new addition of a Jack Russell in 2016. We were told about the benefits of K9JF as we have used TUFFROCK products for many years on our horses & we started the GSD on this product & within a few weeks we could see the results in her wellbeing & her movements. As we live on acreage, both these girls go out hunting most days & enjoy swimming in the dam. Can certainly recommend this product as our GSD is enjoying a full pain free life at at least 10 years old or possibly older as she was a rescue dog from the RSPCA.

    Seeing how it goes

    Posted by Lucinda on 2nd May 2018

    I have not really noticed any difference as yet and my dog does not like the taste so tends to leave her food if I add it in. My dog has had 2 ACL surgeries. Will keep trying.

    I found this product particularly useful for my older dog after he suffered an injury. I've been using it now for about 3 years, and my boy has a spring and vitality back in his step. I've now got all my dogs on K9JF and they're all the better for it! Thank you Tuffrocks!

    As our grey is getting on we found this product with some help from from an adoption group called Friends Of The Hound it seems to help the old girl move.

    Stunningly Great Product!

    My Maltese, Podge, had to have cruciate surgery a few years ago. Upon getting older, he developed some stiffness. I started him on the K9JF as soon as it was released & the results are amazing! (Previously I was giving him the Equine JF!) He’s like a puppy again & has no aches or pains! I really noticed the difference when I ran out a few months ago & within a couple of days, he was slow & didn’t want to move too much. I now make sure that as soon as I open one tub, I go immediately & buy a replacement, I’m never letting him be without it, even for a day!
