Compression sleeves assist pets experiencing joint, tendon, and ligament instability or early fatigue when exercising. They are made to fit the front or rear lower limbs. They are helpful with reducing swelling in the legs and joints, good for protection from annoying sores that won't heal, and supportive for arthritic joints. These are 2.0 mm neoprene support sleeves recommended by veterinary professionals to help keep your pet's smaller joints stronger during exercise. This compression sleeve fits pets with a 2-3" measurement around the lower leg - see sizing chart for more details.
