Seth is a very brave young Maltese-poodle (maltipoo) who had both rear legs severely smashed when he was hit by a car.
He learned to walk on his front legs, balancing himself quite well. That must have been very painful when his legs were shattered.

After extensive surgery, its rear legs have been repaired and Seth has begun to put a bit of weight on them (very tentatively at first). The vet's prognosis is that he will eventually regain full use of his rear legs...
