Oconee County, SC – Oconee County Sheriff’s Office (OCSO) K9 Argo died on May 16 after recently being diagnosed with a terminal illness, according to his department.

The OCSO confirmed the beloved K9’s death in a Facebook post later that day.

“It is with much sadness that we announce the passing of one of our deputy K-9s,” the sheriff’s office said. “K-9 Argo served with the Sheriff’s Office for the past seven years.”

He served alongside his human partner, OCSO First Sergeant Alan Sayre.
