"Hong Kong is rabies-free; we've got very good quarantine system and vaccination system but obviously smuggling puts that at real risk," she said.
She says demand for status dog breeds in Hong Kong comes in waves and normally follows the release of Hollywood films and popular television shows.
"We might get a lot of huskies after a film like 'Below Zero', chihuahuas after all the 'Beverly Hills Chihuahua' films, dalmations after '101 Dalmations.' So we do get cycles, but they tend to be driven by popular culture rather than pure status over who's got the most expensive dog," she added.
Ultimately, the problem of space in Hong Kong has driven home the reality of keeping inappropriate dogs in a highly urban environment. Woodhouse says the SPCA is seeing fewer instances of people keeping three Great Danes in 400 square foot flat.
"I can't say we don't get that anymore, but it's less of a problem than we used to see," she said.
"Way back in the early '90s when pet keeping was becoming popular -- and a lot of the animals were imported from overseas into Hong Kong -- you'd see the scenario where people would turn up with two St. Bernard puppies saying they couldn't afford the vet bills.
"I'd tell them 'Look, if you can't afford the vet bills, how are you going to afford to feed them? Because I can tell you, the bills you'll see today will be nothing next to what you'll have to pay in food in three months' time'."
