The answer to this question is a little complicated. Bingo is not explicitly mentioned in the Archie comics, but he does make an appearance in the show. In the show, Bingo is a white labrador who is owned by Veronica Lodge.
Veronica is shown to be quite fond of Bingo, and she takes great care of him. However, it’s unclear whether or not Bingo is actually a dog in the classic sense of the word. .
Since the comics and show are different mediums, it’s possible that Bingo is not actually a dog in the classic sense of the word. However, given that he is shown to be quite fond of Veronica and takes great care of her, it seems likely that he is considered a dog by her and by viewers of the show.
Therefore, based on this evidence, it would seem that Bingo in Riverdale is indeed a dog.
