Canine units are specialized teams that use trained dogs to assist law enforcement and military operations. These dogs are often skilled in detecting drugs, explosives, and even tracking down missing persons. Handlers work closely with their dogs to ensure effective communication and teamwork during various missions. The dogs in canine units are typically breeds known for their strong sense of smell and intelligence, such as German Shepherds or Belgian Malinois. Training involves teaching the dogs specific tasks and commands, allowing them to perform their duties efficiently in various environments, from urban settings to rural areas.
