Detection dogs are specially trained canines that assist humans in identifying specific substances or items. They use their keen sense of smell to detect things like drugs, explosives, or even certain medical conditions. These dogs undergo rigorous training to learn how to recognize particular scents and alert their handlers when they find them. Detection dogs are commonly used in various fields, including law enforcement, search and rescue, and even in airports for security purposes. Their ability to quickly and accurately locate items makes them valuable partners in ensuring safety and efficiency in many situations.
