I have a couple of friends doing that nosework thing and they like it.
Another thing folks can do is train their dogs to find sheds. (shed antlers) I am actually going to do that for fun. You can sell them too. google that. Fun walk in the woods with your dog and make a little change
Do you have to use a fresh shed to train the dog with? I have several sets of whitetail antlers, but they are pretty old, and they weren't dropped (until I showed up ).
The deer should be dropping them soon (if they haven't done so already), and up around my dad's place (30 monute drive), there are lots of moose too.
