“Responsible dog ownership” has a different meaning in the winter.
It is unrealistic to expect the tenants in my building to suit up to walk their dogs in the middle of the night. What happens is that people let their dogs out in the back lot and watch from the door. Sure there’s the whole “unleashed dog” and “pick up after them” issue, but those are not convincing concerns at 3am with a -20 wind chill.
So every few days I take the shovel to the back lot to pluck the frozen dog-cakes from the snow.
