Copper is a bloodhound and the deuteragonist of Disney's 1981 feature film, The Fox and the Hound and its 2006 midquel. He becomes best friends with Tod the fox, despite that the two should be natural enemies.
Copper is loosely based on a hound dog with the same name that appeared in the novel The Fox and the Hound by Daniel P. Mannix. Besides the major changes between the book and the film, the original Copper was an older dog threatened by a younger dog named Chief (the film seemingly switches the two roles).
In the film, Copper is a Bloodhound/Coonhound mix. His body is light brown with dark brown ears and a dark brown spot on his back. He also has a white muzzle and belly, and four white paws. As an adult, he wears a blue collar.
As a puppy, Copper is fairly curious. He has an excellent sense of smell, which makes him prone to wandering off, following various scents. One of these instances led to him befriending Tod, being unaware that the two were natural enemies. However, he could be slightly cautious, especially around his owner and the older Chief.
As an adult, he is much more serious, having been trained as a hunting dog. However, he does not initially go for Chief's theory that a hunting dog must be nasty, preferring to simply track and smell out a game. His training leads him to break off his relationship with Tod. However, he spares his friend out of past friendship until Chief is injured in an accident, at which time he becomes focused on revenge. However, their friendship would be rekindled, in a distant manner, when Tod saved him and his master from a rampaging bear. Copper would later repay his friend's brave efforts by keeping his still-mad boss from shooting Tod.
He is introduced as a cute small puppy that Amos Slade had recently obtained. Amos Slade intends to train the puppy as a hunting dog, and instructs his older dog Chief to look after him. One day, Copper wanders off, intent on following an unusual scent and ends up meeting Tod the fox kit. The two play together and become good friends, not realizing the two are natural enemies. Copper must keep his friendship secret, and often sneaks off to play with Tod. Copper's owner, Amos, is an avid hunter while Chief is a trained hunting dog, and the two would certainly kill Tod if given the chance. Eventually, Amos grows tired of Copper running off and ties the puppy to his doghouse to keep from running away. Tod comes over to see why Copper isn't coming to play. When he sees that Copper is tied up, the fox kit attempts to play there, but Copper worries that Chief will awaken. Chief awakens after smelling Tod and chases him across the woods with his house still attached. Amos chases after them trying to shoot Tod, believing the fox kit was harassing his chickens. Much to Copper's relief, Tod is able to escape successfully.
Soon after, Copper is taken on a long hunting trip with Slade and Chief. During the winter, Copper grows into an adult and becomes a skilled hunting dog. When spring arrives, Copper returns, having helped Amos obtain a lot of animal skins. That night, an adult Tod comes over to see Copper, but Copper tells Tod that they can no longer continue their friendship. Copper is now a hunting dog, and Tod is a fox. Suddenly, Chief and Amos catch Tod on their property and Copper is forced to track his former friend. Copper doesn't want to see Tod killed, and so he lets the fox get away. However, Chief notices Tod and chases him onto a railroad bridge. When a train comes, Tod is able to escape, but Chief ends up being hit by the train and is severely injured, though not killed. Copper, believing that Tod intended for Chief to get injured by the locomotive, accuses the fox of betraying him and immediately regrets letting Tod go and furiously swears revenge on him.
When Amos and Copper realize that Tod's owner, Widow Tweed has released Tod into the game preserve, the two decide it is the perfect opportunity to get revenge. They are able to track Tod to a den, where he is staying with Vixey, a young female vixen. After Tod quickly escapes the bear traps, Amos and Copper chase him and Vixey. Copper is suddenly stopped by Tod, both growling at each other while being distracted. Copper tries to attack Tod, but the brave fox quickly dodges his teeth and fights back, then sprints away to rejoin Vixey. Copper continues to chase Tod and tries to thrash and claw his way through the fox hole, but Tod drives him out of the burrow, yet Copper continues to dig furiously. Amos sets traps along their path, but the two foxes are able to avoid them. Setting a fire near one den entrance, Copper and Amos wait at the other entrance. Both are shocked when Tod is able to escape the flames and avoid them, and Copper gives chase.
Copper and Amos chase the foxes up the cliff when Copper picks up a new scent, and a look of horror dawns on his face when he realizes what it is. Amos catches up to Copper and aims his gun at the foxes, when suddenly, a huge grizzly bear appears from the bushes. While trying to escape from the bear, Amos is caught into one of his own traps, dropping his gun slightly out of reach. Copper fearlessly lunges at the huge bear to protect his master, and battles him, but is soon overwhelmed when the bear easily overpowers him, and gives him a powerful swipe knocking the dog to the ground. Copper lets out a loud yelp that reaches Tod's ears. Tod turns and is horrified to see his childhood friend getting nearly killed. Just as the bear prepares for the final blow to kill Copper, Tod leaps onto the bear's back and distracts him from Copper. Tod is able to defeat the bear and barely survives falling down the waterfall with it, leaving him immensely hurt and exhausted, collapsing at the riverbank.
Copper approaches, amazed that Tod--the very fox he tried to track down--saved his life, despite everything that had happened, and now feels genuinely remorseful for all the horrors he put him through. When Amos arrives to kill Tod, Copper stands in the way of the gun, refusing to move away, and Amos eventually lowers his gun, sparing Tod's life. With their friendship restored, Tod and Copper share one last smile before parting. Copper returns home with Amos, fondly remembering his friendship with Tod.
Copper is one of the main characters of the midquel, which takes place prior to Copper going hunting with Amos Slade. In the film, Copper feels he is unable to do a lot of things right, whilst Tod tries to list things he can do, however, realizes that at the time of the movie, Copper wasn't even house trained yet. He and Tod later slip away to a country fair, where they encounter a group of stray dogs who formed a band known as the "The Singin' Strays". They find out that the band is preparing to perform, and that a talent scout for the Grand Ole Opry would be in attendance. After the band loses a member, Cash, Copper is recruited to perform after the band hears him sing. Impressed, they offer him a position, which Copper accepts after promising he is a stray. However, his friendship with the band causes him to forget a promise to watch fireworks with Tod.
Tod would later reveal to one of the band members, Dixie, that Copper was not a stray. The two formed a plan to get Copper to leave by leading Amos Slade to the fair. However, the resulting chase ruins the band's performance, resulting in the talent scout leaving and Copper's removal from the band.
Copper and Tod would later admit their mistakes and work to reunite the band. Copper uses his tracking skills to find the talent scout, and he and Copper work to trick the band, including Cash, into coming. Copper helps the band work out their differences, leading to the band performing their song. The talent scout notices the group and is impressed, so he arranges to let them perform at the Opry. However, Copper chooses to leave the band to return home with Tod.
Copper doesn't appear on the show. However, he appeared in the canonical novel Red's Untold Tale. In this version, he was also the hunter's bloodhound, initially unnamed, that belong to Amos Slade, specialized in wolf hunt. After that Amos was slain during a wolf attack, Peter became his new owner and decides to name him Copper.
- In Spain, Brazil and Italy, he is named "Toby".
- Some of Copper's growls when he fights the bear and tries to attack Tod and Vixey in their burrow are recycled from Old Yeller when Old Yeller was fighting the wolf.
- Copper's revenge on Tod is somewhat similar to Zira's revenge on Kovu. Both stay angry and explain about their family relationship's avenging (in Copper's case, Chief falling off the train track and in Zira's case, Nuka getting crushed by a log), but Copper is a hero while Zira is a villain and Chief was Copper's foster father and Nuka is Zira's son.
- It is never explicitly stated if Copper realized that Tod never intended for Chief to fall off the train track, although he might have guessed it when Tod saved him from the giant bear.
- In the book of the same title, Copper is said to be a Coonhound/Bloodhound mix.
- Also in the book, Copper is more like Chief in that he is the older, more experienced hound, and hates Chief (who is younger and less experienced, yet is favored by the Master).
