Front Leg Joint Disease in Dogs: The joints of a dog's front legs lack fat and muscle, making the knees vulnerable to injury from frequent stair climbing or floor friction. Thickened Elbows: This recovery sleeve cushions and shields the elbow area, preventing licking and further irritation. Easy On and Off: Slip the shirt over the head, guide the front legs through, and dressing is done the suit leaves the genitals exposed so dogs can relieve themselves without removal. Multi-purpose: Beyond post-injury support, the garment doubles as cozy pajamas at home or as a lightweight barrier against outdoor dust. Before Ordering: Designed for medium and large dogs only puppies under 20 lbs should not use this product. Choose size by the weight chart on the listing page.
