The Fox and the Hound is a 1981 American animated buddy drama film produced by Walt Disney Productions and loosely based on the 1967 novel of the same name by Daniel P. Mannix. It tells the story of the unlikely friendship between a red fox named Tod and a hound named Copper, as they struggle against their emerging instincts and the realization that they are meant to be adversaries.

The Fox and the Hound is a 1967 novel written by American novelist Daniel P. Mannix and illustrated by John Schoenherr. It follows the lives of Tod, a red fox raised by a human for the first year of his life, and Copper, a half-bloodhound dog owned by a local hunter, referred to as the Master. After Tod causes the death of the man's favorite hound, man and dog relentlessly hunt the fox, against the dual backdrops of a changing human world and Tod's normal life in hunting for food, seeking a mate, and defending his territory. As preparation for writing the novel, Mannix studied foxes, both tame and wild, a wide variety of hunting techniques, and the ways hounds appear to track foxes, seeking to ensure his characters acted realistically.
