FANTASTIC!!!! Our lurcher is 15 and has been on glucosamine supplements for ages.
Unfortunately, it has not kept the stiffness at bay and the old lady has been struggling. We picked up a free sample of Joint Aid for Dogs at a game fair to try (thinking another gimmick) but to our delight our lurcher now looks forward to her walks and is so much better in herself.
Thank you for making her senior years more comfortable, for her at least. I would like to take this opportunity though to add that since this transformation I am now exhausted from all the extra walking especially uphill!
