If Kia goes in someones yard or on a walking path, then I pick it up.

But more often than not, she'll dissapear into the woods to do her buisness and then I don't pick it up. I figure there is no point in me getting poison ivy trying to find it.

Same at the dog park. If she goes out in the open and I see her, I always clean it up. But if she ends up in the woods, then I don't go looking for it. If I don't ever see her poop but have a feeling she has, I'll pick up some other dogs poop just to 'police' the area.
