Master dog trainer Graeme Hall goes behind the scenes at one of Britain's leading animal hospitals. A Springer Spaniel needs surgery after an accident, a Sussex Spaniel learns to walk again, and a Husky has an operation to restore her eyesight.

Patients include a Labrador with a severe chest infection, a Golden Retriever with an unexplained mass all around her chest, and a Miniature Dachshund with a type of a immune disorder.

Doberman Nova has a hole in her heart that requires a life-saving operation. Jack Russell-Pug-cross Roxy has an ectopic ureter requiring high-risk surgery with a 50/50 chance of success.

Major surgeries are carried out on a five-year-old Dachshund and an eight-year-old Chocolate Labrador. Graeme sees the incredible work carried out by the hospital's Oncology team to treat dogs with cancer like eight-year-old Basset Hound Lottie.
