A Tibetan mastiff puppy sold in China for almost $2 million this week, in what could be the most expensive dog sale ever.

A property developer bought the 1-year-old golden-haired mastiff at a luxury pet fair in the province of Zhejiang.

Previously, a red Tibetan mastiff held the record for single most expensive dog. It sold in China for $1.5 million in 2011.

The breed is a large dog that originated in the mountains of Central Asia where they were used to protect homes and livestock.

Known for their thick manes, the dogs can resemble lions, and in 2013, a Chinese zoo made international headlines when it had a well-groomed Tibetan mastiff standing in for the king of the jungle.
