Just because you don't like dogs doing that doesn't mean you can go to your neighbor's house and shoot his dog when it runs up and wants to lick your face. It doesn't matter if the dog wasn't under the man's control at every second. The story makes it clear the dog was in the house and ran past the man to greet the visitor, who killed it. The dog probably did have a collar on, but the whole thing happened so fast that the owner had no time to grab it before Barney Fife started blasting in all directions.

People that let their dogs attack visitors at the door are either low class or drug dealers or both.
