The Guide to Hong Kong addresses many concerns for expats moving to the city. As far as bringing a pet with you, read our article Bringing Along Fido. Some things to consider:

You may also consider Pet relocation services. They take care of all the details, delivering pets for a fee. In general, these services are expensive, but in a stressful move the relief may be worth it.

I would also recommend checking out expat blogs in Hong Kong. They have often been through the move with pets and can offer you their advice. You can also contact expats through the network once you have made a few posts (to prevent spam).

Hope this helps! I hope you will share what you find out with the forum.
