The most common reason for a dog to limp on a back leg is the presence of joint pain. Stiffness after rest usually indicates joint pain and you may notice your dog 'loosening up' with activity. Lameness which worsens with exercise usually indicates soft tissue pain. The Back on Track® Dog Hock Brace is created with our special Welltex® Fabric. It is designed to alleviate pain, promote healing, and facilitate improved mobility. Ideal for both young and aging dogs, to use as a preventative measure, to manage chronic pain symptoms, or to assist in recovery from injury.
