Front Leg Joint Disease in Dogs: The joints of a dog's front legs have little fat or muscle, so the knees can easily be injured when the dog climbs stairs for long periods or drags across rough floors. Thickened Elbows: This recovery sleeve adds extra padding at the elbow to cushion the joint, block licking, and stop irritation from getting worse. Easy On and Off: Slip the shirt over the head, guide the front legs through the sleeves, and the suit is on the rear stays open so both male and female dogs can relieve themselves without removal. Multi-purpose: Beyond post-injury care, the soft fabric works as everyday pajamas at home or as a light dust barrier during outdoor walks. Before Ordering: Designed for medium and large dogs only the smallest suitable weight is 20 lb. Check the size chart on the product page and choose the fit that matches your dog s current weight.
