Tracking is a dog sport that involves your dog searching for a hidden person. It simulates your dog finding a lost person.
At a trial, a track is laid through the bush or through paddocks, and your dog follows one half to two hours later (depending on what level your dog is at), on a 10m lead and tracks along the path the person took, using scent to determine where they walked. They have to take corners, ignore decoy tracks laid over the track, and locate dropped articles along the way.
All Callicoma Kelpies who have competed in tracking have gone on to get their Tracking Championship titles. (This means they have got their TD, then TDX, then T.Ch):
