We had gotten this for our mature dog, Morgan, she is getting up there in age now and is having issues moving around. We were wary about trying this because nothing seemed to be working. We were optimistic though and gave it a try. It turned out to do wonders for her and now she is having no problem moving. We are so happy that we tried this for her. It is able to be purchased on Amazon . I received this product at a discounted rate in exchange for a honest review.
