Hot Dog

Hot Dog is a sheep dog belonging to the Southside Serpents. He made his only appearance in the thirteenth episode of the first season of Riverdale.

Season 1
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.
