Front Leg Joint Disease in Dogs: The joints of a dog's front legs have little fat or muscle, so the elbows can easily be injured when the dog climbs stairs for long periods or drags across rough floors. Thickened Elbows: This recovery sleeve adds soft 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 breathable fabric works as everyday pajamas at home or as a light barrier against dirt and sun during outdoor walks. Before Ordering: Designed for medium and large dogs only choose size by weight chart on the product page not for puppies under 20 lb.
