A dog paralysed in a road accident has been given a new lease of life thanks to a state-of-the-art PEDAL chair which helps her run again. Puffy a Chinese Crested pooch lost the use of her rear legs when she was struck by a car in January 2015. It destroyed the nerve connection to her hind legs and there was nothing that TV's Supervet could do to save her legs. But owners Michael and Danielle Cass refused to give up on their disabled pet who they took on after Danielle's mother Jo's died.
