I use a flashlight, but I only have one dog. When I do the overnight fosters, I leave the poop until the next morning, unless it is a very tame/calm dog. I can't risk having my attention diverted to clean up poop, risking a flight of a dog stressed. I figure my neighbors see me out there picking up poop all.the.time, and they must know I would get it. LOL. I even pick up trash/other poop, just to keep me in their good graces.
