A “detection dog” refers to a specially trained dog that is skilled in detecting or alerting humans to the presence of specific substances or objects. These dogs are commonly used in various fields such as law enforcement, search and rescue operations, and even in some healthcare settings. They are trained to use their heightened sense of smell to identify and locate specific scents, such as drugs, explosives, firearms, or even missing persons. Detection dogs play a crucial role in a wide range of applications where their specialized abilities can be instrumental in ensuring public safety and security.
