Ron now thats very cool!! I would have loved to see your face when your dog strolled up to you carrying your lost buck!

my7-pt, No its not to late, Does your dog currently have a drive to hunt and retrieve? if you have any sheds take every other toy she has away and give her the shed and let her fall in love with it, play fetch and tug a war with it etc.
Then get out in the woods and find as many fresh sheds as possible as soon as possible.
When you find them try your best to keep your scent of them,only handle them with a plastic glove (not latex) or plastic bag etc.
then put them in a plastic garbage bag etc. and then store them in a tupper ware container.
But for now start with any shed regardless of age. If you dont have any I might be able to hook you up with a few or you can buy couple off ebay to get started. What part of central PA. are you from? Pike
