The K9 Unit consists of ten teams with one dog and one deputy per team. In addition to patrolling the Correctional Facility, the Unit assists local police in locating fugitives, missing persons and on drug searches.

The unit also operates a training school for novice and veteran law enforcement K9s and their handlers. As a public service, teams perform demonstrations for schools and at community events.

Former K9 Handler and current Farm Captain, Dan Callahan, plays the bad guy during a demonstration at the April 2008 Arbor Day Event at the Plymouth County Farm.
