But normally if we don't cause trouble that people complain to authorities or some idiotic neighbours complain then nobody will check also one la. Just make sure we take care of them carefully and don't cause trouble to other people,eg: pee poo at other people's house compound and not picking up the poo at public areas such as playground and open air gym

There is law,only poorly executed. If you're a dog owner,please take note,best to prevent problems than cure them.

A good tip for license,get it at the beginning of the year,as all lisence will expire on 31st dec no matter how close to the end of the year you get the lisence.
