Which type of canine is trained to follow the scent of individuals based on articles of personal belongings?

Tracking canines are specifically trained to follow the scent of individuals by using personal items, such as clothing or belongings, that bear the individual's scent. This process typically involves the dog sniffing the article to gather scent information and then following that scent trail to locate the individual. These dogs are adept at distinguishing between various scents, which allows them to stay focused on the specific individual they have been tasked to track.

Air scent canines, on the other hand, are trained to detect the scent in the air and can find a person from a distance without the need for a personal item. Police canines have versatile training that might include narcotics detection, apprehension, or tracking but do not specifically focus on the scent from personal belongings. Human remains detection canines are specialized in locating deceased individuals and are trained to recognize the specific scents associated with human decomposition rather than tracking live individuals.
