When we got our Chocolate Lab many years ago, it was determined that she had bad hips and our vet suggested we put her on Glucosamine/Chondroitin daily. He said that the "human" kind was cheaper and the same as the dog kind which was considerably more expensive. So we kept her on it until she was put to sleep in November. She was 17 years old and seeing her bad hips in X-rays, the new vet couldn't believe she was still going for her walks to the park every day. We had a prescription of Metacam for her which we used only when it seemed she turned her ankle, hip or foot.
