Bingo is a dingo that Peter brings home in "Vestigial Peter" to eat Chip when he becomes annoying. Peter taunts Chip by telling him that Bingo will leave him in a pile on Joe's lawn. Peter tosses Chip a steak to hold, calling it "steak catch". But Chip tosses it back to Peter who tucks it into his pants, prompting Bingo to attack his crotch. When Stewie wanders in about breakfast, Bingo grabs him and runs out the door. As he is being carried off, Stewie calls out for Brian to clear his browser history.
Bingo joins several other animals of the show as well as the cast in singing "Blue Shadows On The Trail" in "Wild Wild West".
