Put the howl early in the edit, just before the reveal, to set up what follows, then follow it with a dramatic dun dun dun as the twist lands and a vine boom when the joke or scare pays off.

This clip holds a single dog letting out one long howl that starts low, rises into a wavering cry and fades away with a faint natural echo. It feels lonely and a little eerie, like an animal calling out in the dark, and that mournful pull can turn a quiet scene sad, tense or oddly funny depending on what sits around it.
