Tracking is a sport that demonstrates a dog's natural ability to recognize and follow a scent trial. It is the foundation for search and rescue work. Unlike other sports in which the dog follows a handler's commands, in tracking the dog is completely in charge for only he knows how to use his nose to follow the track. The AKC sanctions tracking events for purebred dogs. Tracking the Tracking Shelties contains a history of Shelties tracking and lists all titled dogs. ​
