Noel Fitzpatrick treats Labrador Fieval, who needs a hip replacement on both sides, and the programme catches up with some of the pets and owners who benefited from the surgery's pioneering techniques and inventions over the past year, including Labrador cross Scooby, who lost a leg in his fight against cancer, Jasper the puppy, whose legs were so deformed he needed two operations, and Pixie the cat, who gained a bionic limb to help her survive.
