Sad to inform that we didn't manage to catch the mother dog as she is too aware of us trying to corner her..we tried putting pups into the cage but she was too smart to go in. After 2 hours waiting game, we decided to just leave her be. She is not fierce but will stay far away from people.. My friend will inform the boy/her neighbour who feeds her often and even set up a camping tent for her to leash her and call us if and when he managed to gain her trust so that we can maybe get her spayed and get the puppies. Will put a note outside the tent so that no one will disturb her. Thanks Koo and Rena for coming today... :) and dr.chan for the cage.
