Collective "awww": this big fluffball is an original Tibetan Mastiff, who arrived from the Tibetan-populated province of Qinghai, China, and was welcomed by a convoy of 30 black Mercedes cars at the airport. I wasn't surprised about such a awe-inspring greeting . . . once I found out how much this pooch costs. Will you be shocked, too? If you think you know how much this dog costs, take the quiz and see if you're right.
