We used to have a White Trash neighbor who'd let his Pit/Chow/lab mixes run loose, terrorizing anything in their way. They cornered me in my car once, and I had to throw shoes out the sunroof to make them go away. This was when I was married to my ex, who didn't own a gun and wouldn't let me buy one. However, the one time my rescue sheltie got out the gate and was on WTN property, he shot at her three times with a 12 guage. He had no stock of any sort, was just an irresponsible owner. And his dogs killed two of my goats, I'm almost sure of it, because they tried to come back later that day as I was burying them. If I'd had a gun, you bet your sweet chicken booties I would have SSS, and I'm a total wuss! Because if I had shot the dog, called the sheriff, and the owner would have known, he was the type that would have retaliated violently.
Well, he got evicted. Yay!
The rest of my neighbors are good country folk, and we all agree that if any of our dogs get loose and go after each other's stock, they dog gets a warning shot in the butt, either rock salt or .22 guage or BBs. And we let the owner know. After that, is up to us. So far, we've only had to give one warning shot, and that to the Pit/Blue heeler mix that lives about a mile away. He was trying to get to my baby goats I had born in January. My Great Pyr, that I adopted ASAP after kicking out the Ex, let my then fiancee know something wasn't quite right. .22 in the back butt, the dog went home, we saw him the next week healthy and fine with a slight limp and no incliniation to come down our road.
If you can't control your predator-pets, which includes Dogs and Cats, then dont be upset when a legal cause is taken. And in Arkansas, you are within your legal rights to shoot any animal harming your stock, weather it be 2 chickens or 200.
