Just like the men and women in blue, the duty of a police dog is to protect and serve the public. The finely tuned members of a K-9 unit are specially trained to perform different jobs. Some dogs are trained to go on patrol and help officers chase and hold suspects, while others are used to sniff out illegal substances or explosives.
These canine troopers don't go unrewarded—many dogs are credited with saving the lives of police officers and are honored for their service.
