Letting your killer dog run loose repeatedly to kill other people's pets, that is being a total jerk.
The man warned them of what he would do if it killed his animals. They paid their money and made their choice.
Sorry pal but shooting a teenage girl’s dog right in front of her is, absent an immediate need to do it, not something that a real man would ever do. It utterly classless and lacks any sense of chivalry or respect for woman and children. I have no issue with this being legal but I also think the shooter is a total loser. This is the kind of thing that a fellow who feels really inadequate about himself and has zero sense of perspective would do. By the way, did the shooter offer the teenagers earplugs or eye protection, or did he just start plunking away? Did he offer the girl a last pet of her dog before killing it? Give me a break. This is not something a real man would ever do.
