World's Most Expensive Dog

Have you wondered what is the World's Most Expensive Dog? A $600,000 dog that is. Meet the Tibetan Mastiff. This breed can measure up to three feet tall and weigh up to 180 pounds. And in China, these large dogs are all the rage. One couple said they forked over $600,000 for their mastiff, named Yangtze River Number Two, and transported him to their home via a fleet of Mercedes sedans. Their dog was worth the price, they said, because of his pure bloodline, which is extremely rare. After all the money spent, these dogs may not have the qualities to be a perfect pet. Though loyal to their owners, they can be vicious to strangers — and all that hair must shed like crazy. Plus, they're used to breathing at high altitudes, which is a problem for those living at sea-level locations in China.
