The Bottom's Up Leash helps you help your dysplastic, arthritic, post-surgical, or otherwise disabled dog move more comfortably and safely. The leash works by supporting a portion of the dogs hind legs while they walk, or attempt to go up/down stairs. Unlike a towel under the belly, our product allows your dog to eliminate and keeps you from having to stoop over. For quick cleanup, remove only the padded neoprene sleeves and wash with soap and water
