|South Park character|
|Voiced by||Trey Parker|
DogPoo Petuski is a dirty student at South Park Elementary. He was filler in the classroom mainly in first through third seasons, but since the fourth grade only appears occasionally in large group scenes in the playground, gymnasium or hallway. He was known as Dirt in storyboards until his speaking roles.
Originally in the Unaired Pilot, he was seen rolling around in what appears to be a puddle of mud or dog crap during recess with the prototype Token watching him. Later in "The Wacky Molestation Adventure" he, along with Francis is one of Mayor Cartman's Assistants.
"Professor Chaos" was his first speaking role. He was a possible replacement for Kenny, and lamented his status as a supporting character, but didn't survive the first cut. Cartman described him as "more of a prop". He reappeared in "It's a Jersey Thing" as part of Cartman's entourage against Kyle. He is the only member besides Butters to have lines, yelling "GET IT OFF OF ME!" when Snooki rapes him.
He has messy, faded brown hair, and wears a messy brown jacket with dark green trousers or track pants. He has a mark on the right side of his jaw that may be a large mole, scab, dirt stain (similar to Pig-Pen from Peanuts), or actual dog poo. On the left side of his jaw he has a scratch.
His relatively deep voice has a slight Canadian twang to it in "Professor Chaos".
- His last name was long said to be Brasfield by fans, but in "T.M.I." it was revealed to be Petuski.
- A mentally handicapped boy resembling Dog Poo could be noticed in the episodes of the first season. In An Elephant Makes Love to a Pig, he could be seen in the bus for mentally handicapped kids. He was also seen sitting in a hospital in Mr. Hankey, the Christmas Poo.
