Snoopy is the pet beagle from Charles Schulz's Peanuts comic strip, one of the most recognisable cartoon dogs in the world. The exact origin of this particular 'forbidden dog' clip is unclear, as it comes from a user generated soundboard without credited source audio. Online it circulates as a short meme sound for pet content, where creators use the forbidden dog label to joke that an ordinary dog is secretly a menace. Its appeal is the contrast between Snoopy's wholesome image and the mischief on screen, which keeps it in rotation for dog edits and funny animal compilations.
