Hi,
Unfortunately I am not going to be in Hong Kong during that period but should you need a walker for your Frenchie after that period, please do contact me. I am a Frenchie owner myself, mine is almost 8 years old soon. (although she's now living with the rest of my family in Singapore, since I moved here a year ago)
Do let me know if/when you need a walker., here's my e-mail address :

Thank you.
Sajitha
