What did he do? Lmao

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?"
