my pup is 8 weeks old.. i gave a shed to him the other day an he really wouldnt pay much attention to it.. took him out for a "shed hunt" an he jus wanted to eat snow an grass, but ill keep workin with him... he never left 10 feet from my side.. (yet) .id love to train him to find sheds.. hes lab/beagle mix so the darn thing aughta be good for some kinda chasing or finding... lol
