I put the Border Terriers, Tucker and Kilda, in NoseWork classes last summer. It sounded like fun, and everyone who has taken classes agrees that it's fun for the dogs. Sure enough, the BTs love nosework. Then I had an opportunity to take a class with another instructor, so Cozy is taking NoseWork, too.
I think this sport is going to blossom. It's great fun for the dogs, but getting a title is a good challenge. Any dog that has a working nose can participate, even reactive, timid, disabled, elderly, blind, and/or deaf dogs. The handler doesn't need a high level of fitness. Practice isn't expensive, and doesn't require travel. I think trials will become more and more common in the coming years, as more people discover this new sport.
Earlier this month, I was a volunteer for a NoseWork trial held in Denver. Saturday was NoseWork 2, Sunday was Nosework 1. It was a great experience! I learned so much about what to expect when we compete. Spectators are not generally allowed at trials, so being a volunteer was the only way to get to watch. I was a "hall monitor" for a couple of tests, a timer for one vehicle search, and judge's steward for the other vehicle search. I got some great insight into better training and proofing.
Here is a video of one of Cozy's recent classes. This is the second class session with the odor Birch, the first time we've worked outside.
