Redfive, we get those boring petty reports here, too. Like Ft Hood, Virginia Tech, Columbine, that Armish school, some bloke and the IRS and a Piper Cub and on and on it goes. I found when I was in the USA many people are so parochial they don't care about the next county let alone any further away.
Why not kill the dog? If it is worth shooting at then it is worth killing, surely? Or does scaring small brained mammals get you hard? No, that's the muzzle flash, right?

Didn't they train you to close your eyes on firing at night? Even Kevin Costner knows that one ('The Bodyguard' 1992).
My Filipino father in law told me if I wanted to learn to fight for real then I should go and kill a dog. If I can't kill a dog, how could I ever kill a man? He has a point. It's not about picking and choosing, it's about getting it done and having the guts to do it, for real and not just wave it around and talk tough.
