That would be great tool for cleaning up after your dog crapped I think I'll get my neighbor oneLonger than you think. I have a thermal and can see guts from a deer out on our powerline for hours after putting them out there in the cold. My guess would be about 8 hours. Think about this, I can see my dogs pile of dung in the yard for atleast an hour in the cold. It weighs about 1/4 lb? Compare that to a 200+lb animal.
