Not often enough.

During the summer I did pretty good, at least once a week, whenever I had to mow the lawn. During the winter however... Lets just say the snow is mostly melted now and our yard isn't pretty. They tend to poop in just certain ares so I generally can walk around the yard in the poop-free zones. It will be nice when the cold weather stops so I can get back into a regular poop-scooping schedule.
