Tibetan Mastiff

Although considered the most expensive dog breed in the world, the Tibetan Mastiff was formerly placed lower on the list of most expensive animals. But the purebred Red Tibetan Mastiff Big Splash was sold for $1.5 million in 2011. The aggressive dog didn't set the record-long because a Tibetan Mastiff was sold for $1.9 million in China in 2015.

In the near future, the nameless Mastiff is unlikely to be beaten by a more expensive puppy. The Mastiff breeding market in China was growing six years ago because this kind of dog symbolizes success and wealth, but it suddenly crashed, causing prices to plummet. The gigantic animals were released when many breeding facilities were shut down. The massive monsters are now causing problems in rural Tibet. Over 100,000 stray Mastiffs roam the countryside, attacking bears, snow leopards, foxes, and other small mammals.
