Back on Track's Therapeutic Dog Hock Wraps may be ideal for both injury prevention and recovery of your dog's hind legs. They are made of 100% cotton fabric that is infused with our state-of-the-art Welltex technology, leveraging your dog's own body energy to create a soothing far infrared thermal effect. The Dog Hock Wraps have been designed to comfortably fit a dog's hock area and can help relieve soreness in muscles, joints, and tendons. Attached are four strips that allow you to quickly fasten and unfasten the wraps as well as adjust their snugness. For specific injuries, we recommend that you speak with your veterinarian or therapist before starting treatment with our Dog Hock Wraps.
