Vegas

Vegas is a minor character on Riverdale. He is a Labrador Retriever and the pet dog of Fred and Archie Andrews.

Dog Days
Vegas is seen for the first time when Archie is running late for his first day of school. Vegas is seen running after his owner, curious as to what is going on and happy to see Archie. Vegas jumps up at Archie's legs, and Archie, despite being late, takes a moment to pet his dog before leaving. Vegas barks at him as he leaves, and then sits next to Fred.

Fred feeds Vegas bacon as Archie comes down for school. He stood near the stove, looking up to the food being prepared as Fred and Archie discussed Archie's habit of sneaking out in the night, which Fred has been aware of since Archie was eight, when he was sneaking out to Jughead's treehouse.

Archie told Sheriff Keller and Mr. Weatherbee that on July 4th, he was down at Sweetwater River with Vegas, writing songs, when he heard a gunshot. However, this was merely a story that he spun in order to protect his relationship with Geraldine Grundy. As Archie returned home from football practice that evening, Vegas greeted him. He jumped all over Archie as he proceeded to rub him.

Vegas sat in the garage alongside Jughead, who rubbed his head, as a party took place just within the house. They were soon joined by Archie, who was concerned with the arrival of Valerie, his ex-girlfriend.
