K-9 units
The K-9 Units are an integral part of police response. The Sheriff’s Office K-9 Unit includes 20+ handler and K-9 teams. In addition to performing drugs and narcotics searches, they also can provide backup to deputies, locate suspects and victims, and find evidence at or near crime scenes. KCSO recently added a dual certified electronic device detection/emotional support K-9 team.
Remembering K-9 Fury
It is with great sadness that we share the unexpected passing of retired K9 Fury, Fury Von Hollenhund, a dedicated member of the King County Sheriff’s Office and the Pct-4 Special Emphasis Team.
Born on November 26, 2015, Fury began his law enforcement career on February 27, 2017, when he entered Washington State Patrol Narcotics K9 Detection Training. He was certified alongside his handler, Detective Dave Keller, on April 26, 2017, and graduated the following day.
Fury officially began working with the Sheriff’s Office on April 27, 2017, marking the start of a career that would leave a lasting impact. During his time with King County, Fury played a key role in narcotics enforcement efforts, helping seize over 1,000 pounds of drugs worth millions of dollars. His work directly contributed to safer communities and supported countless investigations.
Fury retired in September of last year after more than eight years of service. He was known for his drive, reliability, and the strong partnership he shared with his handler and team. More than just a working dog, Fury was a true teammate and a loyal friend to Detective Keller and his family—something that meant just as much off duty as it did on.
Fury will be remembered for his service, his loyalty, and the role he played both on the team and at home.
Rest easy, Fury. Your watch is over. - Sergeant Brett Davis

Generalist police dogs
Generalist police dog handlers and their partners attend a 12-week (480-hour) training course. During the course, the dog and handler learn to work together through basic obedience and agility. The dog is taught to locate and track human scent, search areas and buildings for suspects, evidence, and how to protect their handler. The handler learns to read and interpret the dog's body language and the noises the dog makes when it has located something and is on a track.
