It's a contest that got really ugly.

A dog named Walle beat out more than 25 other canines at the 25 th annual World's Ugliest Dog Contest held at the Sonoma-Marin Fair in Petaluma, Calif. Friday.

"He's unique," said Tammie Barbee, owner of the four-year old part boxer, beagle and basset dog.

That "uniqueness" earned Walle a trophy and $1,500. Walle is also set to appear on Jimmy Kimmel's show.

"Everybody always says that there's something wrong with him - his head's too big, his back is too short. It's nice to win at something," Barbee said.

Some of the contest's judges included football legend Joe Montana and Jon Provost, who played Timmy on classic television show "Lassie."

"Walle looked like an experiment that went wrong," said Provost.

All of the dogs entered a pre-qualifying round to make sure they're truly "ugly" before taking the stage.

"The advantage of coming to an Ugly Dog Contest is probably - the less you do, the better," said dog owner Dane Andrew.

Owners also had to provide documentation from a veterinarian - proving their dogs were healthy when registering for the contest.
