Which statement about dogs trained for detection is true?

Dogs trained for detection are known to exhibit different alert behaviors depending on the environment in which they are working. This variability is a fundamental aspect of their training and adaptability. For instance, a detection dog may display a heightened sense of alertness in a crowded area or a specific setting where particular scents are more prevalent. Factors such as background noise, the presence of people, or physical space can influence how a dog signals its findings. This aspect of training emphasizes the importance of context in working scenarios, allowing handlers to interpret canine alerts appropriately based on the circumstances present.
