A Boy and His Dog is a cycle of narratives by author Harlan Ellison. The cycle tells the story of an amoral boy (Vic) and his telepathic dog (Blood), who work together as a team to survive in the post-apocalyptic world after a nuclear war. The original 1969 novella was adapted into the 1975 film A Boy and His Dog directed by L.Q. Jones. Both the story and the film were well-received by critics and science fiction fans, but the film was not successful commercially. The original novella was followed by short stories and a graphic novel. The dog in the movie was first in the 1969 Brady Bunch episodes named Tiger.
