Cujo is the titular main antagonist in the novel and film of the same name, Cujo.
Cujo was once the beloved St. Bernard of the Camber family, but was bitten by a rabid bat in the nose when his head got stuck in a bat cave while chasing a rabbit (which was shown at the beginning of the movie).
Cujo then went mad with rabies and killed any person he came across including one of his own owners.
In the end of both the book and movie, Cujo was seemingly killed by Tad's mother, Donna (who also tried to save her son from dying of heatstroke), by being shot by the sheriff's gun. In the novel he is killed after being hit by a baseball bat.
Cujo appears to have survived the gun shot and makes a cameo appearance in the film Cat's Eye, where he is shown chasing the film's titular cat. (Or it could be another dog of the same breed.)
- He was voiced by Frank Welker who also voiced the two Disney villains, Reggie and Butch the Bulldog, and he also did the MGM villain, Killer the Bulldog.
