As seen in Paper Mario: The Thousand-Year Door
Doogans are creatures which bear somewhat of a resemblance to dogs. So far, they have only made appearances in the Paper Mario games. The badge shop owners Rowf, and his son Rhuff, who can be found in east Toad Town in Paper Mario, are the first Doogans to make an appearance (although the species had no name until Paper Mario: The Thousand-Year Door), and the only ones found in Paper Mario. In Paper Mario: The Thousand-Year Door most Doogans are thugs seen around Rogueport and the Glitz Pit.
