Duke, Renville County Sheriff’s Office K-9 officer, to retire this week

Duke, the Renville County Sheriff’s Office’s K-9 officer, Duke, is set to retire Thursday, April 28, after nine years on the job.

On patrol since 2013, Duke was the Renville County Sheriff’s Office’s first K-9 officer. He was assigned to Deputy Luke Jacques throughout his career. On Duke’s first case, he was responsible for the recovery of 10 ounces of methamphetamine and the seizure of $2,200 in drug money seized from a dealer passing through Renville County.

Through their partnership, Luke and Duke recovered controlled substances, located missing people,  and searched for and apprehended offenders fleeing law enforcement.  Luke and Duke have made many appearances at special events and civic group meetings, and have talked to hundreds of kids at area schools about the Sheriff’s Office, law enforcement and police K-9s.

In addition to being a narcotics-detecting dog, Duke was trained in tracking human odor and in criminal apprehension, which includes holding suspects when instructed to do so.  However, in multiple instances, Duke’s mere presence and loud barking was enough to convince suspects to surrender.

“Duke’s bark, ferocious growl and huge teeth are very intimidating.” said Deputy Jacques.  “However, he is one of the most loving and approachable K-9s, especially with kids, that I’ve met.  He can turn his aggression on and off like it’s on a switch.”

Duke’s success was partly because of support he received from various sources within the community.  As an example, an anonymous donor came forward and donated the protective ballistic vest that Duke wore.  Duke received veterinary care throughout his career, donated by Dr. Diane Hansgen at the Fairfax Veterinary Clinic and Chiropractor Brian Boen at Health Enhancement in Bird Island.  A separate anonymous donor donated all of Duke’s food.

Following his retirement, due to age and declining physical abilities, it is anticipated  Duke will continue to live with Deputy Jacques and his family, which is where he has resided throughout his life.

“Duke has been a really great dog and it has been an honor to be his handler.” concluded Deputy Jacques.  “We’re looking forward to allowing him to live life at a much slower pace in retirement.”

The Renville County Sheriff’s Office is hoping to acquire another dog in the near future to replace Duke and continue the K-9 program in Renville County.
