I think the mistake was to go into detail about the dog killing.
Had she said, “I’ve lived on a farm all my life. You do things that are necessary, but hard. I’ve had to put animals down, that were life long pets, horses, cattle. I once took in a dog that was too aggressive for the family that raised it. I tried to train it to hunt, but the dog was vicious, killing chickens, biting me and at the time my kids were young, and I worried about the dog biting them. So, I put it down.”
etc etc etc. No one would have thought twice about it.
Why she humanized the dog, with pictures no less is beyond my comprehensionl
