PETALUMA, Calif. -- In a gallery of faces only a pet owner could love, Gus -- a one-eyed, three-legged Chinese Crested from St. Petersburg, Fla. -- has won the annual World’s Ugliest Dog Contest at the Sonoma-Marin Fair.

Before a raucous crowd, Gus was crowned on Friday night dethroning 2007 champ Elwood, a formerly homeless Chinese Crested owned by Karen Quigley of New Jersey.

While the crowd hooted and hollered, Gus seemed to not have a care in the world as he slept in the arms of his owner, Jeanenne Teed, during much of the three-hour event.

"Elwood has been enjoying his reign as the 2007 World’s Ugliest Dog," Quigley said prior to the announcement of the results of the online balloting. "Since he was homeless once himself, he has become an ambassador helping other homeless dogs find their forever homes."

Gus took home two trophies and $1,600 in prize money, which his owners are going to put toward his radiation treatments. Gus has skin cancer, which led to the amputation of one leg.

His missing eye was the result of a fight with a tomcat, fair officials said.

Gus also will likely show up on the national media circuit.

Over the years, the winner has gone on to charm Jay Leno and appear on the Morning Show, Geraldo and Inside Edition. Elwood appeared on The View with Barbara Walters after last year’s win.
