The Police Service Dog Unit provides specialized support to the members of the Police Service. A Police Service Dog (PSD) can track by direct scent of the human body or by ground scent. The PSD can provide assistance in arrest of suspects, identification of persons and objects, search and rescue, arrest of armed/dangerous offenders, protection of Police facilities and equipment, security patrols, narcotic searches, tactical response unit positions, and searching for lost or stolen property. The Police Service deploys two PSD's when it is at full strength.
