Getting an introduction to Tiger - a 176 pound (80 kilogram) Tibetan mastiff kept on the roof space of a cramped five-story village house in Hong Kong's New Territories -- is a complicated process.
...
The current vogue for Tibetan mastiffs in mainland China -- where the nouveau riche have reportedly paid as much as US$750,000 for prize-winning specimens -- has reached Hong Kong, though keeping big dogs in a city where the average flat size is just 484 square feet (45 square meters) presents a dangerous challenge.
Tiger's owners, who did not want to be named because of the sensitivity of the issue, know only too well how much trouble a Tibetan mastiff can cause.
