Tracking in Schutzhund is very precise. The dog must follow each footstep with a deep nose at a consistent speed. Articles should be indicated quickly, Bullet indicates his with a down.
As I'm training this I look for more than just a down. He must be straight, lying in a sphynx position with the article between his front paws. Not only that, but I want his attention 100% on the object. No turning his head to glance at me or the judge.
While this is not an article on a track, it shows the intense focus I mark and reward.
