K9 is an acronym used commonly throughout the security sector and police forces to reference trained detection, tracking or security dogs working alongside qualified handlers. They provide invaluable support that goes far beyond the abilities of human officers.

A proper K-9 unit relies on the right dog, the right handler and the right training. Good recordkeeping and ongoing training help prove that the unit is reliable. Read on Sierra Canine for more information.
The term K9 is an abbreviation used commonly throughout the security sector and police forces to refer to trained detection, tracking or security dogs working alongside qualified handlers to prevent, deter and respond to criminal activity or break-ins. They are a valuable resource for tracing missing people, sniffing out illegal substances and searching buildings or open spaces. They also work with law enforcement officers to track suspects who flee the scene of a crime or attempt to evade capture.
Detection K9s excel in scent detection, sniffing out narcotics and explosives as well as cell phones and firearms. Their acute sense of smell allows them to locate these items quicker and more accurately than human officers, who can often miss the odors due to environmental factors. Detection canines are also utilized in search and rescue operations, locating individuals in disaster situations such as floods or collapsed buildings.
The canine’s olfactory sense is said to be over 1000 times better than that of humans, meaning they are more sensitive to certain odors and smells. This ability enables them to detect dangerous chemicals or biological threats that might otherwise be missed by human officers, which saves time and money for agencies.
A detection dog’s rapid and accurate detection also allows it to cover a greater area in the same amount of time as a human officer. This makes them an ideal tool for search and rescue missions or large scale security screenings where speed and efficiency are critical.
When the K-9’s specialized training is applied, they can quickly find and pinpoint the specific odor of the targeted substance, alerting their handlers to its presence. This method is highly effective, as the canine is able to pick up on even microscopic traces of the target substance.
Another important aspect of a K-9’s training is preparing it for its role in crowd control and public safety during events or protests. This can help to disperse the crowd, prevent violent incidents and provide support for law enforcement personnel during such scenarios. K-9 teams also participate in community engagement activities, demonstrating professionalism and transparency with the public to build trust.
Tracking
The term “K9” has been used throughout the security industry and police force to refer to trained detection, tracking or patrol dogs that work alongside qualified handlers to prevent, deter and respond to criminal activity and break-ins. K9s offer a unique value in the field, providing valuable information that is otherwise unobtainable by human officers and complementing existing law enforcement protocols. Their versatility and dedicated service contribute to their continued success in policing and enhancing public safety.
A canine’s sense of smell is extremely sensitive, which allows them to locate people, even in challenging environments such as dense forests or collapsed buildings. Detection K9s are often employed in search and rescue operations to track down missing persons or survivors of disaster situations such as hurricanes or building collapses.
In pursuit operations, the canine is often on a leash to ensure the safety of both officer and suspect. Whether on-leash or off-lead, the canine should always remain within the control of its handler to prevent it from attacking people or running off. However, a handler may decide to allow the canine to track an offender on its own in certain circumstances where it is judged appropriate to do so.
Training for tracking is a lengthy process. In addition to developing a strong hunt drive and conditioning basic searching behavior, the K9 Nose Work(r) training system requires that dogs be exposed to four different search elements before being introduced to target odors (container, interior, exterior and vehicle). The delay in introducing a specific odor allows dogs to build the necessary skills for tracking and to learn that they must be focused on their task and cannot become distracted by other scents.
The specialized training of a K9 can be costly and time-consuming, which is why the service is typically provided by law enforcement agencies or other government entities rather than private companies. As a result, many K9 teams are under a great deal of pressure to provide their services effectively while minimizing costs. In spite of these challenges, many agencies believe that a K9 team’s ability to reduce the likelihood of injury to officers is well worth the expense and risk associated with the use of a canine.
Patrol
K9 teams work with patrol officers to provide a visible deterrent against criminal activity and assist with search and surveillance operations. They also assist in locating illegal drugs during searches of vehicles, buildings and open areas as well as assisting with tracking suspects who flee from the scene of a crime or evade capture.
K-9 teams also work in support of other bureaus within the sheriff’s office. For example, they are deployed for crowd control during large events or protests and may help maintain the safety of both the public and law enforcement personnel. They are also trained to sniff out explosives or firearms during the course of arresting suspects.
They can also be used to search vehicles and property during a traffic stop or when a criminal investigation warrants such a search. Finally, they can be used in the pursuit of fleeing suspects – an operation that requires specialized training as well as the physical and mental abilities of both the dog and its handler.
Police often claim that the presence of a K9 can help coerce suspect behavior without the need for force. They assert that the dogs psychologically intimidate suspects and make them realize that immediate compliance is the only way to avoid injury or death. While this assertion appears plausible, it is based on observational data rather than experimental evidence. The use of force by police is common, with some estimates claiming that upwards of 160 officers are assaulted daily. K9 units may help reduce the frequency of this type of violent incident, but they are not likely to fundamentally change the overall risk of officer injury or the amount of resistance encountered during arrests.
Some K9 units are also trained to detect items beyond narcotics and explosives, including mobile phones, toxic mold, and currency. They are especially useful in correctional facilities and may be able to spot contraband before it can cause injury or harm. However, these specialty units require special training and must be recertified annually to ensure that they continue to meet performance standards.
Community Relations
In addition to tracking suspects and patrol work, some police service dogs are also trained as comfort dogs. Comfort K9s, sometimes referred to as therapy dogs, visit people who are suffering from stress or need a little affection. Officers and their dogs visit students who are stressed about exams or coping with tragedy, residents in nursing homes and rehabilitation centers, and more. UMB Police and Public Safety is the third university police department in the country to have a comfort dog program. Our comfort dog, Poe, and his handler, PFC Anthony Summers, can be scheduled to meet with you in person or virtually.
Community relations is a broad term that encompasses many different initiatives and strategies to connect businesses with their local communities. These may include sponsorships, donations, volunteering, and partnering with other businesses in the area to promote mutual interests and boost economic growth. These activities are meant to build a positive image for a business and foster goodwill in the community, which can then be used as a marketing strategy to attract new customers.
Unfortunately, even when a K9 is properly trained and deployed in the right circumstances, there will be instances where an innocent citizen or bystander gets attacked by a law enforcement canine. In these cases, it is often the fault of the police agency for failing to take proper precautions when training their K9s.
