SHERMAN, Tex. -- After more than four years of service, one of Sherman’s K-9 officers is retiring.

Six-year-old Oskar has been a major asset to the department, helping with criminal convictions of drug dealers in the area.

Oskar was diagnosed with a form of canine diabetes a few years ago. While his health is fine right now, it is his age that is affecting his ability to perform.

Oskar has had two trainers during his time with the department. He will live with the first one for the rest of his life.

The Sherman Police Department has ordered a new K-9. No word on when he will arrive. Sherman police have one other k-9 officer.
