The exact original video behind this phrase is not clearly documented, but the clip circulates online as a short Spanish meme sound, shared and reused in short-form edits where the joke depends on recognition rather than explanation. Its appeal comes from the familiar saying structure: a dog and a habit are easy visual shorthand for stubborn behaviour, so creators can pair it with pets, friends or celebrities without needing subtitles for Spanish-speaking viewers. That simple, repeatable setup keeps it useful for reaction videos and everyday jokes.
