I like Harley but the pit I had before the 2 I have now was named Harley.
My neighbor and friend had a German Shepard that was one of the nicest dogs I ever met and used to strange people since they own a junkyard and the dog is there all the time. The meter reader that came there sprayed him with mace when he went over to say hello. Same as you describe, tail wagging so hard his whole back end was going side to side.
