Which of the following is a passive indication of a K9?

A passive indication refers to a behavior exhibited by a K9 that suggests the presence of narcotics without an aggressive or active response. The action of pointing is characterized by the dog remaining relatively still, with either their nose or their body aimed at a specific location, which conveys to the handler that the dog has detected something of interest, such as narcotics.

This type of indication is particularly valuable in narcotics detection, as it allows for a clear and controlled communication between the K9 and handler without causing alarm or escalating the situation. It minimizes the likelihood of disturbing the area or the evidence of narcotics, which may be crucial for the integrity of the investigation.

In contrast, active indications such as scratching, biting, or barking represent more aggressive or overt behaviors, signaling the presence of narcotics in a less controlled manner. These actions might draw more attention, potentially complicating the situation or affecting the K9's ability to locate or confirm the presence of narcotics quietly. Thus, pointing is the behavior that best fits the criteria for a passive indication in K9 narcotics detection.
