A dog who served with the Toronto Police Service for seven years has died after a medical emergency on Saturday.

On Saturday evening, police responded to a call about a person with a gun in the area of the Don Valley Parkway and Wynford Drive. Const. Allyson Douglas-Cook said the caller believed someone tossed a firearm in a bushy, or wooded area.

When units responded, no gun was found, and the Toronto Police Dog Services were called for support.

Kash, a German Shepherd, and his handler Const. Matthew Butt attended the scene, and Kash was able to recover the firearm, said police.

Following the call, Const. Butt returned to the station and realized Kash was under medical distress.

"He took him to the local emergency vet service, and unfortunately he didn't make it, and he passed away overnight," Douglas-Cook told CBC News.
