"Princess Abby," a 4-year-old chihuahua, strolls the red carpet after winning the World's Ugliest Dog Contest at the Sonoma-Marin Fair Friday, June 25, 2010, in Petaluma, Calif. While "Princess Abby" appears to be taking a bow, her hind legs are actually taller than her front legs. Celebrity vet Karen "Doc" Halligan says the dog's problematic back, legs and a closed-up left eye may be due to being inbred. "She's a poster child to spay and neuter your pets," she said.
