Why are Tibetan Mastiffs so expensive

Tibetan Mastiff (Detailed Introduction)
We all know a major characteristic of Tibetan Mastiffs is loyalty, so many people want to raise one to guard their home, but when it comes to its price, many feel the Tibetan Mastiff is as unreachable as a flower in a mirror or the moon’s reflection in water. Indeed, Tibetan Mastiffs have always been top-priced among dogs, but why are Tibetan Mastiffs so expensive? What traits do they have to give them such value?
According to statistics, a purebred young Tibetan Mastiff may cost between 20,000 to hundreds of thousands. Of course, a purebred rare adult Tibetan Mastiff can cost hundreds of thousands, millions, or even tens of millions; truly sky-high prices.
The reason Tibetan Mastiffs are expensive also has its causes. As the saying goes, "scarcity makes something precious," and Tibetan Mastiffs can be said to be very precious dogs. Their history is long; surveys show Tibetan Mastiffs are recognized worldwide as the oldest and only surviving rare breed. Because of this rarity, combined with the charm of the Tibetan Mastiff itself, its value rises. Also, their reproductive rate and cub survival rate are quite low, so their high price is justified.
Many people, seeing the commercial value of Tibetan Mastiffs, began aggressively breeding them. Although this may have somewhat altered the traditional use of Tibetan Mastiffs, this practice is not entirely useless; at least it allows this ancient breed to be preserved.
