Are you those registered tenants with dogs? If so, you don't have to be afraid. There is no official announcement about policy change so I think you should check with housing department first. Please also contact dogs associations (eg SPCAA) and just in case, you may also contact press agency (newspaper) to ask for public support. PLEASE NEVER GIVE UP YOUR DEAR OLD FRIEND. I adopted a dog four years ago because he was given up by his previous owner (live in public housing) and I picked him from a dog assoication before his 'deadline'.
Good Luck.
