Police dogs, also known as K-9 (a play on the word “canine”), have been assisting law enforcement and the military for hundreds of years. These highly trained dogs work alongside policemen for various tasks such as tracking missing people, detecting narcotics, and clearing dangerous areas.
K-9 units are also used for search and rescue missions and help collect criminal evidence due to their amazing sense of smell. Apart from their law enforcement duties, they also serve as therapy dogs, providing emotional support to their owners.
