 The Otter Tail County Sheriff's Office has a new canine officer. Canine Koa is a two-year-old German shepherd from Slovakia. Koa and his handler, Deputy Kelby Jensen, are working to become a certified canine team, a 13-week process. Koa will be trained for narcotics detection, searches, tracking, and apprehension. Koa replaces canine Mojo, who retired this spring after nine years with the Sheriff's Office.
