Noel Fitzpatrick and his team treat Staffordshire bull terrier Lulu, who has been hit by a car and had her pelvis smashed into more than 25 pieces. The professor's only option is to pin the larger pieces back together in an operation that will require all his expertise. Noel and his team also treat a giant schnauzer called Florence who has a sore knee and a pointy-eared Jack Russell called Muffin who has a mysterious problem with her back legs.
