I always clean up after my dog. It is to respect the house owners and other park users. In addition, we hope (my family) what we do can have some influence on other people who also take their dogs out for a walk. We hope they can have some sense of being responsible and respecting others if they see we always pick up after our dogs.
Wow from what you guys said, the situation around Richmond apartment areas sounds VERY bad I have lived in my house for over 8 years and so far I have rarely seen any abandoned dog poop around the area and the neighbouring school and parks.
