That is one of the things talked about on CNN with this story. The cop did try to pepper spray and did Tase the dog. Taser didn't work...dog rolled over and tried to remove prongs. One tough dog. Animal services arrived and took the dog.
I know some would have just shot the dog, thank goodness these did not.
The dog was a guard dog at I think was a welding garage. The owner had a make-shift lock instead of a real lock on the gate of the shop fence. A policeman had pulled on to the lot to use radar on the highway. The dog got out and attacked the car. Guess the dog was trying to protect the property, but went a little overboard. No one was bitten, but I have enjoyed watching this video.
