Dallas police say a retired K9 officer has passed away.
Mirko had an incurable illness, and today his partner and other officers honored him as he was escorted to the veterinarian to be laid to rest.
He had been with the department for seven years and just retired in May.
Mirko helped his partner Senior Corporal Armando Dominguez find critical missing persons and helped catch suspects.
The department says although he's gone, he will never be forgotten.
