Only in Dog Runs you can let your dogs run freely - and only couple of dog runs available. Unfortunately these places are far away from city center. You might sneakingly let your dog run freely at places like Mc Ritchie reservoir - but here labrador and dalmation are considered as 'big' dog and locals might horrified when they see them run freely..
You cant have your dog on public transport. If you dont have a car, you have to get a cab, and not every cab driver are willing to get your doggies hopped in, especially 'big' dogs like yours. Worse, only few places happily let your pets staying with you while you eating or dringkin - even in outdoor restaurants. Locals might get used to with toy dogs (wee dogs) but not big ones - most likely they will call the restaurant managers and complain.
I dont accuse all Singaporeans do not love their dogs - I know it's only some of them. Just cant stand what I see everyday.. they dont bother when their dogs want to stop n sniff - just keep talking on their mobiles and pull that very short lead.

they have dogs as either toys or status.
I think, Singapore as a country, and some Singaporean, are not dog friendly.
