James Herriot. A spoiled dog Tricki is overfed by his owner Mrs Pumphrey until he falls ill. The vet (narrator) hospitalises Tricki — refuses special food and lets him exercise naturally with other dogs. Tricki recovers completely. Mrs Pumphrey calls it 'a triumph of surgery' — irony: no surgery was needed! Just diet and exercise. Theme: Overindulgence harms; tough love heals.
