hi liat,
just a few questions, have you actually received a formal letter from the management or their lawyers requesting the removal of your dog? was it just a note saying that pets are not allowed in the building?
usually, no matter what property you buy in hong kong, even if the developer promotes it as pet-friendly, has stipulations on the land deed that no pets are allowed. in most cases, the management needs to receive 3 complaints from residents before they can take action.
in my case, the same thing happened to me but after so many years, nothing happened after the first complaint and the neighbours / residents have become rather friendly.
i haven't heard of any legal action being taken in hong kong to remove a pet apart from mei foo sun chuen which has a strict no-pet policy and they will take immediate action legally.
give it some time when you move in and you might be pleasantly surprised.
out of curiosity, could you mention the building you are moving into?
don't forget that dogs need time to adapt to their new surroundings and often bark at strange noises in their new environment.
good luck liat and keep us informed.
