Dogs interpret the world mostly by smell. It is said that dogs can smell 100,000 times better than humans.  Dogs with the use of their noses can be trained to find lost people, animals and victims of disaster.  Tracking is a dog sport that demonstrates a dog’s natural ability to recognize and follow a scent and is the foundation of canine search and rescue.  Unlike other companion dog events such as obedience and rally where a dog responds to a handler, with tracking your dog is completely in charge, for only they can recognize a scent and follow the track.
