Yoda's short tufts of hair, protruding tongue and long, seemingly hairless legs were enough to earn it the World's Ugliest Dog title at a northern California fair.
The 14-year-old Chinese crested and Chihuahua mix won the honour at the 23rd annual contest at the Sonoma Marin Fair.
Owner Terry Schumacher, of Hanford, California, said the 2lb dog has come a long way since she was found abandoned behind an apartment building.
Ms Schumacher said she first thought the pooch was a rat.
Yoda's distinction comes a year after a one-eyed Chihuahua named Princess Abby claimed victory. A pedigree Chinese crested won in 2008 and another Chinese crested and Chihuahua mix was the ugliest in 2007.
In past years, the winner's owner has received a 1,000 dollar (£625) cheque.
