K-9 & Patrol


Billy side view

Over the past few years there has been an increase in illegal drug use in Benton County. Two years ago, Sheriff Knox addressed this problem with the purchase and training of a K-9 drug detection dog.

Billy is a Belgian Malinois, is four years old and who along with his handler, Deputy Andy Ehlers, were trained by Code 2 K-9 in Omaha Nebraska. Billy is especially adept at finding the odor of Marijuana, Methamphetamine, Cocaine and Heroin. This makes him very valuable in Benton County where these are some of the most abused drugs.

K-9 Billy works a regular shift and is also on 24-hour call, should a search be required. He is used on vehicle stops, residence checks and searching the Detention Unit. Part of his duties involve a weekly training regimen, as well as, periodic re-certification and training. He conducts about 100 searches a year and is generally very busy.

Deputy Ehlers is assigned to the Patrol Division, and in addition to his duties as a K-9 handler, answers calls for service, makes reports and provides traditional patrol activities.

Since Billy does not spend all his time searching for drugs, he has become very popular visiting area schools, assisting with the D.A.R.E. program and other community events. These activities provide a positive community outreach, which is important to provide a positive interaction with the Sheriff’s Office.

It is hoped that sometime in the future, the Sheriff’s Office will be able to provide a second K-9 and handler to assist with the task of Narcotics Enforcement. This dog could also assume additional duties, such as, search and recovery of missing persons or suspects, which would be huge benefit.

K-9s are what we call a force multiplier in that they significantly add to our capabilities. K-9 Billy has been invaluable assisting Deputies in the recovery of narcotics and prosecution of suspects. His abilities are exceptional making him a true ‘Wonder Dog’.
