Weld County Sheriff's Office K9 Unit

K9Web-3.jpg

The Weld County Sheriff’s Office has four K9 teams working in the Patrol Division and two working in the Weld County Jail. Dogs are certified to do narcotics detection, tracking and suspect capture. Each dog is paired with a deputy who acts as their handler. The dog lives with their handler and is their partner at work.

The K9 Unit trains together multiple times each month to ensure handlers and their dogs are working as efficiently and as effectively as possible. Joining the K9 Unit for regular trainings is the Decoy Team, which is made up of deputies from other units in both the patrol and detentions divisions. Members of the Decoy Team bring a real-life element to K9 training scenarios that would otherwise be difficult to imitate with dummies and other training equipment.
