Our LIVE dog training classroom is here: https://dogtraining.world/register
Dogs already know how to follow the scent of a person and track. We only train the dog when to track and what to track. Trailing is a broad term that allows the dog to follow scent in the way that makes the hunt easiest for the dog at the moment. Pure tracking is following footsteps only which may not always have human scent present and is best suited for competitive sports. Visit https://www.dogtraining.world for more info.
