The Most Expensive Dog in the World - The Red Tibetan Mastiff is the most expensive dog in the world. This ancient guarding breed has recently become something of a status symbol among China’s uber-wealthy class. They viewed as a “pure Chinese” breed because of its well-documented history and nearly exclusive Chinese population.The most expensive Tibetan Mastiff ever sold is named Big Splash, or "Hong Dong" in Chinese, who sold for 10 million Yuan (about 1.5 million US Dollars).
