Tibetan Mastiff becomes world's priciest dog: Chinese woman pays $600,000

Would you pay more than a half a million dollars for a dog? A woman from Northern China has just taken delivery of what has reportedly become the most expensive dog in the world for which she paid 4 million yuan, or about $600,000.

The 18-month-old Tibetan mastiff, called Yangtze River Number Two, arrived at its new home in Xi'an yesterday.
