The wife brought home a new lab last fall, against my wishes ( we already have 2). I figured I would try to teach her to find sheds since I really got back into looking for them last spring. So from the time we had her all she ever had to chew on was a shed, it progressed to fetch and eventually to hiding them from her in the yard. I would give her a treat when she was younger every time she would bring it back, she picked it up pretty quick. She is now 9 months old and my son and I took her up to a buddies property and left her in the truck while we took an armful of sheds and placed them out in the woods in various spots. I hung a peice of toilet paper in the trees in the vacinity of the sheds so I wouldn't forget where i put them. She did amazing it is so fun to watch her work. She found every one of them with no guidance from me what so ever. I couldn't believe it. I can't wait to get her out there and look for some brownies, the next month is going to be torture.
