Which behavior signifies that a dog has detected a target odor?

The behavior that signifies a dog has detected a target odor is known as indication. This term specifically refers to the actions taken by the dog to alert the handler that they have found a scent. Typical indications include sitting, staying, or locating a particular area where the scent is the strongest. This behavior is crucial for effective detection work, as it provides the handler with clear communication about the presence of the target odor.

While searching refers to the process where the dog actively investigates an area in search of a scent, it does not necessarily indicate that the target odor has been detected. Falsing, on the other hand, refers to when a dog incorrectly indicates the presence of an odor when there is none, which is not a reliable behavior. Ranging involves the dog moving back and forth over a larger area to locate the source of a scent, which may occur prior to an indication but does not signify detection on its own. Indication is the definitive behavior that confirms a successful detection.
