Hot Dog is a sheep dog belonging to the Southside Serpents. He made his first appearance in the thirteenth episode of the first season of Riverdale, and appears in the eighteenth episode as an initiation step for Jughead's entrance into the gang.
Guarding Hot Dog is the first trial of the Serpents Initiation, used in the process of becoming an official member of the Southside Serpents. Every member had to take care of Hot Dog at some point. It was later revealed by Toni Topaz, that Hot Dog is actually the Serpents' third pet dog, given the same name "Hot Dog", as the previous before him.
Hot Dog was brought along by the Serpents when they visited Jughead Jones at his father's trailer at the Sunnyside Trailer Park. They came to offer him membership within the gang; an offer he accepted. Hot Dog originally barked and growled at Jughead when he answered the door, but after one of the Serpents told him to settle down, claiming that Jughead was family, he did so almost instantly and sat quietly while Jughead and the Serpents talked.
- Hot Dog was a frequent character in the Archie Comics and was Jughead's dog and best friend.
