LOS ANGELES, CA - DECEMBER 15: Shelter worker Laura Guyden holds a chihuahua that awaits adoption at a Los Angeles Department of Animal Services shelter on December 15, 2009 in os Angeles, California. December 15, 2009 in Los Angeles, California. Chihuahuas make up about a third of the dogs at many California shelters, so many that some shelters are shipping Chihuahuas to other states to find homes. A shelter in Oakland sent about 100 to Arizona, Oregon and Washington. Recently, a Los Angeles city shelter flew 25 Chihuahuas to Nashua, New Hampshire where all found homes within a day through the local Humane Society. Experts have blamed the glut of abandoned Chihuahuas in California on the influence of pop culture, a bad economy, puppy mills and backyard breeders. Fans sometimes abandon the dogs when they are no longer new and cute to them or when expensive vet bills start to add up. The tiny dogs are named for the Mexican state of Chihuahua.
