Please let me explain. Once a dog gets a taste for livestock they will remain a livestock killer forever. Give the dog away and it will escape just to kill again. The best thing to do is put it down.
I spoke with someone at the local humane society about it once when trying to get information on how to train my dog. The lady from the humane society recommended that I put my dog to sleep. It has something to do with a “prey drive” instinct that can’t be trained away once it’s been activated.
You are obviously a dog lover, I get it. I’ve never been without a dog in my life except when I was deployed. But something that is also obvious is that you are not a farmer. Please don’t get mad at something you don’t understand. It makes you sound like a liberal college idiot.
