"I get this product for my labs as well as my older dog, that has arthritis....it makes for easier movement and less pain, as they age. Our 4 yr old lab takes it, and our 9 yr old lab, and my 15 yr old boy, it really helps him w/ getting up and down, and around easier....doesn't wake up in the morning stiff. Great product if you care about your pets joints and aging. :0)"
