Police dogs
Police dogs, commonly referred to as K-9 officers, play a significant role in law enforcement, assisting in various missions due to their specialized training and unique abilities. The use of dogs in policing began in Belgium in 1899, with the first deployment of Belgian sheepdogs, and made its way to the United States by 1907. By 2024, there were an estimated 50,000 police dogs serving across the U.S. These canines are selected for their intelligence, loyalty, exceptional sense of smell, and natural aggression, with breeds like German shepherds and Doberman pinschers being particularly favored. Their acute olfactory capabilities allow them to detect substances at incredibly low concentrations, making them invaluable for tasks such as searching for explosives, drugs, and missing persons.
The role of police dogs has expanded in response to rising security concerns, especially regarding terrorism. However, the deployment of these dogs raises legal and ethical questions, particularly concerning the use of force in apprehending suspects. The U.S. Supreme Court has addressed issues related to the legality of police dog usage in several landmark cases, clarifying the conditions under which their alerts can be considered probable cause for searches and the limits on their use during traffic stops. Ongoing discussions continue to shape the legal framework surrounding the employment of police dogs in law enforcement.

SIGNIFICANCE: Police dogs are now trained in more varied and diverse missions than ever before.
Dogs’ work in law enforcement began in Belgium in 1899, with the deployment of Belgian sheepdogs, and quickly spread through the law-enforcement agencies around the world. Police dogs were first used in the United States by the New York City Police Department in 1907. The growth in the police dog service has been explosive; Jim Watson, director of the North American Police Work Dog Association, estimated that there were more than fifty thousand police dogs serving law-enforcement agencies in the United States in 2024. These dogs are referred to as K-9 (shorthand for canine) officers.
Different breeds of dogs have been trained for police work. Trainers find that a dog needs to have a distinct set of characteristics for police work. These traits include intelligence, loyalty, an excellent sense of smell, and natural aggression. The breeds most often chosen are Belgian sheepdogs, German shepherds, Doberman pinschers, and a variety of hounds and beagles. The last two groups are used primarily for tracking and smell detection. Non-neutered male dogs are used for their natural aggression.
During the early twenty-first century with heightened awareness of terrorism, the role of police dogs and their companion officers expanded dramatically. A dog’s sense of smell is fifty times more acute than that of its human companion. Dogs can smell substances present in trace amounts of less than 1 gram, and some are 70 percent more effective than odor detection machines. These olfactory skills are put to use searching for explosives, drugs, and people.
The use of police dogs has seen challenges to its legality. When a large, well-trained dog attacks and bites a suspect, the question of reasonable force can arise. The US Supreme Court has heard two cases that address this issue of deadly force. In 1985, Tennessee v. Garner reviewed the Fourth Amendment and the use of deadly force. In 1989, Graham v. Connor discussed the “reasonableness” of the use of force by a police dog. In 2013, the Supreme Court held in its ruling in Florida v. Harris that a drug-detection dog's alert to an officer provides probable cause for officers to conduct a warrantless search of a vehicle, without requiring any other evidence of the dog's reliability so long as it has been certified. In Rodriguez v. United States (2015), the Supreme Court ruled that, under the Fourth Amendment, law enforcement officers cannot prolong traffic stops in order to wait for drug-sniffing dogs to inspect stopped vehicles unless there is reasonable suspicion that a crime has been committed. At the appellate court level, almost all circuits have heard cases discussing the deployment of police dogs, their training, and what constitutes reasonable force.
