Tux and I like to do nosework. We do have a kit with Birch odor in it, though I haven't gotten that out in years. More recently I have started training him to find deer antler sheds. We have a couple of sheds to use to practice. He was also an active Barn Hunt competitor, and has his Open title and a leg towards Senior. But due to some recently arthritic issues I made the decision to retire him from that. So we signed up for a nosework/intro to tracking class that starts in Feb. I don't plan on competing in nosework with him, but might break out the birch to hide the odor for him to find it just for fun.
