My dog is 9 years old and has had two ACL surgeries. I have used a variety of other supplements and pain meds on and off over the years to help him stay flexible and strong in his back legs. This product is the best that I have used.
Not only is it affordable and easy to get, it has made a world of difference. My dog can jump on furniture that he could not prior to taking this. I give them the supplement everyday and I continue to see the improvement in the way he runs and moves in general.
I very strongly recommend this product!
