Jughead Jones - Hot Dog

Hot Dog is Jughead's dog, though when he first appeared in Pep Comics # 224 (December, 1968), he belonged to Archie. Because of some confusion between the Archie Comics artists and the Filmation animation studio, Hot Dog switched owners frequently when he started appearing more. Hot Dog was eventually given a permanent home at Jughead's.

Hot Dog is a long-haired mutt who resembles a sheepdog. He usually thinks like a human in that his thoughts are presented in voice-over (or thought bubble in the comics) to the audience as asides where the dog's mouth does not move. Hot Dog is lazy, constantly hungry, and has a dislike for Reggie Mantle, much like Jughead. When Jughead's family objected to Hot Dog living indoors because he was covered in dirt, Dilton Doiley built Hot Dog a doghouse full of whimsical inventions, which was the kickoff plot for the miniseries Hot Dog.

Hot Dog is usually considered a member of Archie's Gang. He is also the mascot for The Archies. In the Filmation series, he is often seen pretending to "conduct" the band. He tends to be attracted to Veronica’s pedigreed dogs, and even had a litter of puppies with one of them, a poodle named Lucretia. In the 1970s Sabrina the Teenage Witch, Hot Dog had a sidekick, Chili Dog, who was smaller and red haired. A running gag was the two dogs' "battles" with Sabrina's cat Salem Saberhagen
