The novel ends several months later with both the Trenton and Camber families trying to move on with their lives. Donna has completed her treatment for rabies and her marriage to Vic has survived. Charity gives Brett a new, vaccinated puppy named Willie. A postscript says that the hole Cujo chased the rabbit into was not discovered. It also reminds the reader that Cujo was a good dog who always tried to keep his owners happy, but the ravage of rabies drove him to violence.
