Conflicting. On one hand, he had all right to shot the dogs. On the other hand, he really shouldn't even feel proud of it. Does anyone really want to shoot a dog? Does anyone really want to kill another persons pet?
I understand being happy that you protected your animals, and being happy that they're safe now. But the dogs are innocent - they don't know any better. It's the owners fault.
Completely agree what he did was right, he gave warnings and had to protect his animals. But he really shouldn't have posted it on facebook, much less be so proud about it. Ravens and foxes annoy me to no end, killing chickens and such. But I still wouldn't be terribly happy killing them just for following their instincts trying to live.
Bah, whatever. Just for future reference, don't tweet or instagram or facebook killing dogs. Doesn't end too well too often.
