Tibetan Mastiff Puppies Price?

I heard that a pure Tibetan mastiff pup would cost anywhere from $50,000.00 to $70,000.00. Is it true? What's the real price of the puppies?
I know they love Tibetan Mastiff Puppies in china. Wealthy Chinese are apparently crazy about Tibetan Mastiff. Unlike status-seeking westerners and their pocket pooches, Chinese with big incomes are dropping a lot of money on the Tibetan mastiff, a regal-looking large dog that was originally bred by the nomads of Central Asia.

Is there any pet clubs in the U.S. that sell or might provide further price info about such puppies?

A black Tibetan Mastiff, 31 inches high and answering to the name of "Yangtze River Number Two," is believed to have broken the world record as the most expensive dog after a Chinese woman paid $582,000 for the “priceless” canine.

In September a woman in Xi'an spent some $600,000 on an 18-month-old Tibetan mastiff. That dog's arrival was greeted by a 30-car convoy from the airport and host of events with his owner.

Providing the proper balance of exercise. Young Tibetan Mastiffs need enough exercise to keep them lean and healthy, but not so much that their soft growing bones, joints, and ligaments become over-stressed and damaged. Adult Tibetan Mastiffs need more exercise to keep them in shape, but not in hot or humid weather for fear of overheating.

When you acquire a puppy, you're acquiring potential -- what he one day will be. So "typical breed characteristics" are very important. But when you acquire an adult, you're acquiring what he already IS.

Tibetan mastiffs are one of those pets that are far from cheap. A nice doggie from the Tibetan Mastiff breed can fetch between $40,000 and more than $1 million.
The Tibetan Mastiff has a long history. It was used as a guardian of herds, flocks, tents, villages, monasteries, and palaces in China. If you can afford to have a Tibetan Mastiff, then you are obviously wealthy, is the consideration in China.
