Place this clip at the reaction beat after the pet's action, then follow it with the Nelson Ha Ha Sound Effect for a second mocking layer, or precede it with the Goofy Ahh Running Sound when the joke starts with a chase.
About this sound
This is a roughly ten-second mixed clip built around a playful, human-like dog laugh used as a reaction cue. It lands as pure goofy silliness, making a still grin, stare or side-eye feel like the dog is in on the joke and laughing along with everyone watching it.
