With his huge head, oversize paws and duck waddle, Walle beat out 29 other contestants at the annual competition, hosted by the Sonoma-Marin Fair in Petaluma, Calif.
Brian Sobel, one of the judges, said of Walle: "This dog looked like he's been Photoshopped with pieces from various dogs and maybe a few other animals."
We were so inspired by Walle's looks that we decided to take a look back at the last decade of the World's Ugliest Dog contest. Get to know Sam, Yoda, Princess Abby and many other past winners here.
