A buddie and I were out looking for the sheds of a few local bt bucks near home, we found a small spike that was fresh. When we got home I threw it in a big pile of sheds in the corner of the room, later when I let my lab come inside her nose hit the flore and she ran to the pile of sheds and pulled out that fresh spike shed. From then on I was a believer and take her every time I go!
