One time I was walking in a city park early morning with no one around.

Heard a noise and saw a pit bull charging me at full speed. An almost full grown pup.

The dog slammed on the brakes and stopped about 10 feet from me and started wagging his tail. In fact, he was wagging the whole back half of his body.

He just wanted some petting.

It would have been a shame to have shot that dog.
