A friendly St. Bernard named "Cujo" contracts rabies and conducts a reign of terror on a small American town.

[Joe Camber has encountered Cujo in the garage. Cujo glares at him menacingly & growls]
Joe Camber: Cujo?
[the dog snarls again, and approaches him menacingly]
Joe Camber: Oh my God... you're rabid!
[Cujo barks savagely and charges at Joe. He puts his arms up to defend himself as Cujo attacks]
Joe Camber: [yelling] NO! NO! CUJO!
[the dog jumps on him & knocks him down]
Donna Trenton: Fuck you, dog.
Professor: Nope. Nothing wrong here.
Joe Camber: You better watch it, Pervier.
[Joe looks down and pats Cujo]
Joe Camber: I'll sic my dog on you.
Gary Pervier: That dog? You couldn't sic that dog on me if I was comin' at you with a straight razor in each hand!
Vic Trenton: There are no real monsters.
Tad Trenton: Except for the one in my closet.
Donna Trenton: Please God get me out of here.
Donna Trenton: [Tad starts hyperventilating] Not now!
Tad Trenton: [in the car] Can he get us in here?
Donna Trenton: No.
Tad Trenton: Can he eat his way in here? Can he?
Donna Trenton: No.
Tad Trenton: Wish he was dead.
Donna Trenton: Me too.
Donna Trenton: Damn this car!
