HKD 25,000 would be the monthly rent for a smallish flat, or a village house, depending on location. Importing a dog to Hong Kong from Oz would entail one weeks quarantine for you pooch, make sure all innoculations are current. Best location with a dog would be out of the city in Clearwater Bay or Sai Kung or even Disco Bay. You might not be able to find a suitable place with a garden but most apartments come with balconies and there are plenty of places where you can take your dog for walkies. Once you get settled, you'll probably employ an Amah, who can look after your dog as part of her duties. I have lots of friends in Hong Kong who keep big dogs, living in apartments without gardens.
