The linked Guardian has the longer version. Training wasn’t going well, but she made a spur of the moment decision that training was done. No rethinking said training. No spaying to keep the traits out of the bloodline. No deciding if a different role in the household would be appropriate. No rehoming the dog to one without birds. No rescue or even a county shelter. Not even a sober discussion with her kids to let them say goodbye and then a humane euthanasia.
No, the dog embarrassed her and cost her money, so she shot it. Then, she was in a killin’ mood, so the goat had to go too, apparently the same day. And she did a bad job with that one so it sat there with a gunshot wound until she could get to the truck and back, and there were other people in sight, so it was all safe and well thought out (/s).
Then she brags about it like it was a good thing. I will stand by it: people in rural areas and in agriculture have to have a different relationship with mammalian life and death and have to make tough calls, but this shithead is just cruel.
