Raxs waxs, seems to work well and make shure you wash sheds so your sent isnt on them or if your dog picks them up wash as well so its sent isnt on them. Figure out weather your dog likes to play or likes treats for reward, and keep on it persistance pays off. also train him to sit or bark when he finds one sometimes they cant carry them back so they will pass right on by. i have had great luck with this method my dog is 2 and he has already found around 13 sheds. good luck thats a nice lookin pup.
