The vet we took our pets to when I was a kid had photos of his patients in the waiting room. One showed a beagle who had been hit by a car and couldn't use it's back legs, possibly spinal damage or possibly pelvic damage. The vet had made a "wheelchair" with a sling for the the dog's hips to sit in, hung from crossbars which connected by two inverted A-frames to wide-tired wheels.
He couldn't run but he could get around. I always used to wonder how he marked his territory, though.
