World's Most Expensive Dog ($582,000)

It sounds like a shaggy dog story, but it isn't. A Tibetan Mastiff is believed to have broken the record as the world's most expensive dog — sold to a young Chinese millionaire for a mind-blowing $582,000 in September 2009. The owner, known only as Ms. Wang, traveled to Qinghai province of northwest China to purchase the 18-month old dog, named Yangtze River Number Two. Yangtze came home to an A-List entrance at Xi'an airport in China's Shaanxi province, where he was reportedly greeted by hordes of dog lovers and picked up by a motorcade of 30 black Mercedes-Benz cars.
