My understanding is that tracking dogs scent by the small almost invisible particles of skin and whatnot that fall from our bodies constantly. I think that if someone used a shirt or jacket or whatever, the dogs would lose scent pretty quickly because there would be a limited number of particles for them to track, and, the particles on the item would be older than particles that actually came from the person they are tracking.
Please correct me if I am wrong. Thanks!
Yep, you got it right.
