No single movie or show is credited for this clip, and it circulates mainly as a short user shared soundboard effect built from two familiar noises. The joke spread because barking and fart sounds are both instantly readable without any setup, so creators reuse it across pet memes, gaming edits and reaction videos. It sits in the same toilet humor family as a fart with reverb, but this version is shorter and sharper, relying on the dog bark to set up the surprise before the payoff.
