Rear End Support Leash
This type of harness attaches around the dog's hind legs and around the pelvic area. It is designed to help dogs with broken hind legs regain the strength in their broken legs. When the dog owner pulls up on the leash, the pressure on the hind legs decreases, which is good for dogs who broke their hind legs and took so long to heal that the muscles atrophied, because their legs may not be strong enough to hold the dog's full weight. The rear end support leash is also thought to relieve dogs of the pain from arthritis, dysplasia, and other skeletal or muscular problems that originate in the dog's hindquarters.
Mid-Region Support
The mid-region support harness is a wide strap that goes under the abdominal region of the dog. The strap is attached to handles, and like the rear end support leash, the mid-region support harness uses pressure from the owner pulling upward on the handles to ease the downward pressure on that region, thereby eliciting therapeutic effects on the dog's muscular and skeletal structure. The mid-region support harness is designed for dogs that suffer from general weakness of the legs, but it is also used in post-surgical rehabilitation.
Dog Wheelchair
The dog wheelchair was designed for dogs that have no use for their back legs. Whether the canine's legs are paralyzed, broken or removed entirely, the dog wheelchair can help these crippled dogs get around. The harness attaches to the rear of the dog in much the same way as the harness on the rear end support leash, but connects to metal poles that go along the dog's sides, towards the head. At the front of the dog's body, there is another harness that goes around the dog's chest and neck. In the very back, the poles are connected to a set of wheels that go down further than the length of the dog's legs, so the hind legs do not touch the ground and the dog can move using its front two feet.
One of the harder facts of life to accept is that living bodies eventually break down. As the body deteriorates, some parts break, some parts fall off, and other parts cease to function. This fact of life is even more difficult when you have to watch the deterioration process in someone you love, such as a dog. Fortunately, humanity has invented dog lift harness systems, which can keep humans and their dogs together and active, even if the dog would naturally be immobile.
