Recently, a Tibetan Mastiff was sold in China for a whopping $2 million, making it the most expensive dog ever. Originally from Nepal and China, the Tibetan Mastiff can grow to 160 pounds and stand over 33 inches at the shoulder. In early times, the breed was used to guard flocks and homes from leopards and wolves.
Anyone thinking about getting one should figure in the cost of obedience school. Tibetan Mastiffs tend to be headstrong and strong-willed.
