In our last house we had a next-door neighbor with a very dangerous pit bull. If I had been enlightened to the merits of gun ownership at the time, I would have shot this dog on more than one occasion with no regrets.
Sounds like it must not have been that dangerous of a dog as from your statement it appears you had ecounters with it on more than 1 occassion and are alive to tell about it.
Maybe there are details you left out, but based off this statement alone it doesn't sound like shooting the dog would be justified.
