Police dog

It was the end of the day when I parked my police van in front of the station. As I gathered my equipment, my K-9 partner, Jake, was barking, and I saw a little boy staring in at me.

"Is that a dog you got back there?" he asked.

"It sure is," I replied.

Puzzled, the boy looked at me and then towards the back of the van. Finally he said, "What'd he do?"
