While there's not as much scent on an antler as there is on, say, a mallard, Dokken says there's enough for a dog to key on. "The bone itself has some scent, but the most odor comes from a waxy substance found right at the base of the antler, where it attaches to the skull. Once I have the dog working away from me and hunting well by sight, I apply a liberal dose of 'Rack Wax' (sheddogtrainer.com), a product that mimics the smell of this waxy substance, to the tines and beam. Now when I run the dog on the silhouettes, I make sure we're working into the wind, so the dog has the advantage of his nose. When it's time to remove the silhouettes, I like to drop the antlers in about the same area for awhile, then extend the distance a bit and make the dog work. Once I feel he's getting the hang of it, I'll start dropping antlers in fields with taller grass, so I know he's really using his nose to find them."
