I have been training my Doberman/Shepard mix named Clyde, after Drexler, to do nosework. They use their nose to detect target smells (in this case Birch). Maybe one day Clyde will be good enough to hunt for truffles out in the woods. Here is a video I took on Saturday when we practiced at home. Sorry if it makes you all a little dizzy. I had to edit it down for twitter.
