Shed-hunting with dogs

This is a sport I had not heard of until reading about it in the StarTribune today:

Josh [Miller], of New Richmond, Wis., and [his dog] Easton are at the forefront of what in recent years has been a fast-growing hobby, and now is a fast-growing nationwide sport: shed hunting.

Not sheds as in buildings where lawn mowers are stored. But sheds as in antlers dropped each year in winter by whitetail bucks.

"Hunting'' for the dropped antlers, or sheds, in spring as snow melts has become increasingly popular among sporting types, as deer numbers have increased...

"I took Easton along with me for the exercise, and while I looked for sheds, he kept finding tennis balls,'' Josh said. "He's a nut for tennis balls, and he seems to find them everywhere. That's what got me thinking: Why couldn't I train Easton to find sheds for me?'' ...

Here's how the competition is conducted:

To simulate the smell during competitions, a product called Rack Wax is rubbed onto the bases of antlers. Six antlers are then planted in three separate fields, each measuring about 15 acres.

Points are awarded for each rack found by a dog, and each time a rack is delivered by a dog to its handler. The quicker this occurs, the higher the score awarded.

Despite my thousands of hours in the woods, I've only found one "shed," probably because most of my woods time is in late summer/autumn, by which time scavenging animals have found the antlers first.
