Looking ruff: Zsa Zsa the English bulldog wins World's Ugliest Dog competition

A nine-year-old English bulldog named Zsa Zsa has won the World’s Ugliest Dog competition.

Zsa Zsa was announced the winner of the 2018 World's Ugliest Dog contest at the Sonoma-Marin Sonoma-Marin Fairgrounds in Petaluma, California, on Saturday.

The dog's owner Megan Brainard of Anoka, Minnesota, will receive $1,500 for her dog's win.

Ms Brainard found Zsa Zsa on a pet-finding site, according to the contest bio.

Dogs in the annual competition flaunted their imperfections - some with hairless bodies, others with lolling tongues.

The dogs were walked by their handlers down a red carpet where they were evaluated by a panel of judges.

The contestants included a blackhead-covered Chinese Crested-Dachshund mutt, a bulldog mix with excess wrinkly skin and a Pekingese named Wild Thang.

Last year's winner was a 125-pound (57-kilogram) gentle giant named Martha - a Neopolitan Mastiff with gas and a droopy face.

The contest is in its 30th year. It is usually held on Friday nights, but organisers moved the competition to Saturday in an effort to draw a bigger audience.
