The Walkabout™ Rear Harness is a temporary hand held support system for dogs that are WEAK IN THE REAR LEGS. It is made of black/blue neoprene is machine washable, needs to be air dried and comes in various sizes from X Small to X Large. It has two holes for the legs to go down through and then wraps up over the hips with a Velcro closure and one or two snaps depending on the size of the sling. The small and extra small harnesses need only one handle for support while the other sizes have two handles. This product is a true back saver for personal use, Vet Hospitals, or Rehabilitation Clinics. This is the original and simply the best hand-held sling on the market. If you are tall and have a short dog, extension handles are available, at an additional cost of $5, so that you are able to walk upright when supporting your pet or you can slip a leash though the handles to make your own extension. If your pet does not fit into any definite size, custom slings may be ordered at an additional cost of $30. We will advise if that is necessary when you call us. As the Walkabout™ harness is very comfortable it may be left on your pet for short periods of time so that, for example, when indoors you can just grab the handle when necessary to aid your pet to an upright position. This sling can also be used to help your pet in and out of the K-9 Cart.
