How does kinetic theory explain how a dog could find you by your scent?

Kinetic theory explains that molecules are in constant motion, and when a dog sniffs, it detects airborne scent molecules that have dispersed into the environment. These scent molecules, produced by substances in the surroundings or on a person's skin, move randomly and collide with the dog's olfactory receptors. The dog's highly sensitive nose is equipped with a large number of olfactory receptors, allowing it to identify and track these scent molecules back to their source, enabling it to locate a person by their unique scent.
