LOOK: Sweepee Rambo, the 'Ugliest' Dog in the World

Sweepee Rambo, a 17-year-old female dog, was recently hailed as the ugliest dog in the world.

On June 27, Sweepee, along with 16 other dogs, gathered at the Sonoma-Marin Fairgrounds to compete for the most unconventional pet title.

According to the Press Democrat, this is the third time for Sweepee to join the competition which has been going on for 28 years.

The pets are judged based on bad appearance, including stench, poor complexion and a host of other inherited and acquired maladies, the report added.

Sweepee--who had her whole family to support her--is a Chinese Crested Chihuahua mix weighing only 4 pounds. Her hair was styled in a mohawk and her ears are as big as bat ears.

Sweepee has an eye condition, making the other one yellow and the other blue. But what made her win is her ooze.

People said Sweepee has managed to escape several dog pounds before ultimately ending up with her current owner, Jason Wurtz.

In an interview, Wurtz told TIME that the chihuahua was originally a gift to his ex-wife. Wurtz took possession af the dog after they split.

"I've had girlfriends over the years and they were jealous of her and like I told them, she was here when you came and she'll be here when you leave, that's the best friend I have," he told TIME.

Most pet owners would not want their pet to be called the "ugliest," but according to Erin Post, CEO of the Sonoma-Marin Fair, the event does not aim to belittle or mock theappearances of the dogs but to celebrate them.

"We're proud to celebrate all dogs and pets by showing that no matter their imperfections, they are adoptable, lovable and a great add to any family," Post told ABC News.

Chief judge Brian Sobel told BBC that judging the dogs was not easy as many people they think. "Scoring was tough with so many uniquely qualified dogs but we're confident that Sweepee will be a magnificent champion!"

Sweepee's owner won $1,500 and a six-foot trophy.
