If your pup is suffering from hip and joint pain, prolotherapy may be an option. Here's an interesting article that describes how it works:

WHAT IS PROLOTHERAPY?
Joints weaken when ligaments and tendons are stretched, torn or fragmented, causing the joint to become hyper-mobile and painful. Traditional approaches with anti-infl ammatory drugs and surgery often fail to stabilize these joints and relieve pain permanently. Prolotherapy has the unique ability to directly address the cause of instability and repair weakened sites, resulting in permanent joint stabilization. Also known as ligament reconstructive therapy, prolotherapy is a recognized human orthopedic procedure that stimulates the body’s natural healing processes to strengthen joints weakened by trauma or arthritis.

HOW DOES IT WORK?
When precisely injected into the site of pain or injury, prolotherapy creates a mild, controlled inflammation that stimulates the body to lay down new tendon or ligament fibers, resulting in a strengthening of the weakened structure. Tendons and ligaments have immature cells known as fibroblasts. These are kind of like dormant “baby” cells, and when stimulated, they grow and create new tendon fribrils, which themselves grow and create new tendon. Electron micrographs actually show this growth and transformation. When the ligaments and/or tendons becomes strong, the joint will stabilize and the pain will be relieved!
