The 'What the Dog Doin' meme originated from a Vine video uploaded in 2011 by Tony Fu, featuring a group of friends reaching for a tin of Mint Breakers when a dog unexpectedly sticks its head into the circle. One of the men famously asks, 'What the dog doin'?' in a humorous, slightly confused tone. The phrase resurfaced years later on TikTok and Twitter, evolving into a catchphrase used whenever a dog or person is behaving strangely or inserting themselves into a situation where they do not belong. It has since become a staple of surrealist and shitposting culture, often paired with sound effects or distorted visuals to heighten the comedic absurdity of the dog's curious behavior.
