Sai means get out in Portuguese, and cachorro means dog, so the phrase is a blunt command that Brazilian and Portuguese speaking users turned into a meme reaction sound online. Its exact original recording is not widely documented, but the clip spread through soundboards, short videos and messaging apps because the delivery is easy to understand across languages. It is now used less as a real command to an animal and more as a comic way to shoo away pets, friends or unwanted intruders in edits.

Sai Cachorro is a short Portuguese meme clip of someone shouting at a dog to get out, used in funny edits, reaction videos and pet videos online.
Sai Cachorro is a loud, exasperated shout in Portuguese telling a dog to get out, delivered with the urgent, half annoyed and half comic energy of someone shooing a pet away from food, shoes or furniture. The phrase is sharp, repeated in feeling if not in words, and instantly readable even if you do not speak Portuguese because the tone does all the work. It lands like a scolding and a punchline at once, turning an ordinary pet moment into a dramatic, overreacting scene that feels made for short memes.
