My friend trained his Lab to retrieve sheds.  He'd toss antlers in the kennel with it and let it play with them.  The he'd lay some in the yard within sight, and have the dog retrieve them.  Next he'd hide some around the yard and tell him to fetch up the bones. Lastly he took him out to the hills and hid a few and had him find them.  He did pretty good, but had trouble dragging some of the bigger elk sheds back up out of a canyon. 

There's a kennel in southern Oregon that's training dogs fro shed hunting.  Their best dogs are something called a Puddlepointer?  Uglier than sin, but I guess their nose can really sniff out discarded antlers! 

Gotta love a good dog and it doesn't surprise me at all that multiple breeds have been taught to be good shed hunters! It's all about the hunt, the find & the reward of the love ya give em for being a good dog!

yep...I am tryin to keep up with the management of our herd...the dogs are great for helping find the sheds in the spring....
