You had to say "pull the trigger" didn't you?! I had a dog when I was a kid, part shepard/part coyote (grew up in the desert on farm land). Perhaps, we just assumed he was that type of mutt because he came home with all sorts of crazy critters. He came home with someone's prize rooster one morning. Not too long after that, he came home with a bullet hole and a dragging leg. My mom's boyfriend came over (yes my dad knew about him) to put my dog down. I was inside the house when I heard the gunshot so I immediately ran outside balling only to see my not-yet-dead dog get shot in the head - first shot didn't do the job, the one I saw did the job too well to forget. Took years to want another dog!
I was raised on a farm too. Only horses (and MAYBE a cow) got Vet care. I've yet to use a gun on any animal. Saw way too much of that growing up. I'm all for hunting the hunters. Way more sporting when your target is armed
