You've probably heard the urban legend about people adopting foreign dogs that turn out to be sewer rats. Terry Schumacher of California actually thought her dog Yoda was a rat when she first saw her. She adopted the the 14-year-old Chinese crested and Chihuahua mix after finding her abandoned behind an apartment building. This weekend Yoda brought honor to the family name (and a $1,000 check) when she was crowned this year's World's Ugliest Dog at the Sonoma Marin Fair.
