K-9 police dogs are trained for detecting explosives and narcotics, search and rescue, and subduing suspects. Police dogs and their handlers work as a team and usually live with the handler in order to remain friendly and social. Once a police dog retires they can remain with the handler’s family or be adopted by a suitable home. Police dogs can play an important part in law enforcement, and in many jurisdictions, killing or injuring a police dog is considered a felony. It is not uncommon for memorial services to be held after the death of a K-9 who valiantly served his duties.
