The Fox and the Hound is loosely based on Daniel P. Mannix’ novel, however almost everything in the book was either changed or removed in the film. In the novel:
- Todd had two vixens that he mates and has cubs with, all of whom are killed by the hunter
- Todd intentionally kills The Chief by jumping out of the way of an oncoming train
- Todd dies from exhaustion while being chased by Copper
- the hunter was an old drunk and the novel ends with the hunter being sent to a retirement home and because dogs aren’t allowed he’s forced to shoot Copper.
Understandably, that would have made for a pretty grim children’s movie.
