For intruder detection at Level 3, how far must the dog detect and respond to the sound made by a person downwind?

In the context of Level 3 intruder detection, a trained detection dog must be able to detect and respond to sounds made by a person downwind from a distance of 100 feet. This distance is based on the dog's exceptional hearing capabilities, which allow them to pick up a wide range of sounds that humans typically cannot hear. The training that these dogs undergo prepares them for real-world scenarios, ensuring they can effectively alert their handlers to potential threats even from a considerable distance.

Furthermore, achieving this level of detection is crucial for maintaining security, as it allows for significant reaction time and the potential to deter intruders before they can approach a vulnerable area. The requirement for the detection range reflects the rigorous standards set for canine performance in security operations.
