Scooby the Labrador has a life-threatening tumor in his leg and his family hopes that Noel can save him; Noel also goes to great lengths to save the life of Tiger the cat.

Noel operates on a five-month-old Rufus, a rabbit with a badly broken hind leg and he diagnoses that a much-loved cocker spaniel called Dixie needs major spinal surgery.

Young Staffie puppy Jasper's legs are growing in the wrong direction and out of shape; he must be operated on soon if they're to have any chance of correcting the problem; Labrador Mojo must have spinal surgery or face paralysis.

Noel believes he can help make Pixie, a 12-year-old cat that was hit by a car, walk again by giving her a revolutionary bionic implant.

Schrodinger is a cat with a shattered thigh bone due to being hit by a car; the feline belongs to seven-year-old Shoshana, who has the auto-immune condition known as PANDAS.

A dachshund called Frankie is brought in by owners Kelly and Daniel to see if Noel can do anything to repair a deformity in his foot. A ten-month-old Labrador needs a hip replacement before he can begin his training as a medical alert dog to help his owner with her rare health condition. And Emily, an eight-year-old shih-tzu from Bognor Regis, needs an operation to fix her spine which is extremely risky, presenting her owners with an agonising decision.
