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.
Fangs Fogarty informs Serpents during Cheryl Blossom's End-of-Summer party that the Ghoulies have kidnapped Hot Dog. They, lead by Jughead, go to rescue Hot Dog. His attempt is at first challenged by the Ghoulies, Malachai and Penny Peabody, but they are stopped when Cheryl injures Malachai with an arrow, allowing Jughead, Hot Dog and the Serpents to leave.
- Hot Dog was a frequent character in the Archie Comics and was Jughead's dog and best friend.
