In the first of a new series, Professor Noel Fitzpatrick and his team treat a giant Newfoundland puppy with a painful knee and shoulder. What appears straightforward quickly turns into a much bigger concern, and Noel and his team are challenged to invent not one but two new implants for her. Meanwhile, a rescue black Labrador called Moogi is in need of treatment for severe elbow arthritis, and a golden Labrador born with a deformed front paw is offered a bionic solution in the form of a unique, custom-made prosthesis.
