Plot

Donna Trenton (Dee Wallace Stone) is a frustrated suburban housewife whose life is in turmoil after her husband learns about her having an affair. Brett Camber (Billy Jayne) is a young boy whose only companion is a Saint-Bernard named “Cujo”, who in turn is bitten by a bat with rabies and becomes violent. When Donna and her young son Tad drive into the countryside and into the home where Cujo and his owners live, they didn’t realize Cujo is out there waiting for them thanks to becoming insane by the bat that bit him which makes him a cold-blooded killer. Donna and Tad attempt to survive whilst Cujo attempts to kill them, as he has killed one of his own owners.

Trivia

• Many times, a Rottweiler was used as Cujo, because they couldn’t get a St. Bernard to look mean enough.

• In one scene, you can see the dog’s tail tied to his rear leg. The dogs playing Cujo were very friendly dogs and the director needed them to stop wagging their tails.

• Just before Cujo kills the police officer you can clearly see him wagging his tail.

• Film Debut of Danny Pintauro
