Wow. I just read on her history with animals. I did not know this.

Sometimes livestock is "put out of its misery", especially if they're in incredible pain and not likely to live. That's normal. Except, she was breeding dogs for the purposes of hunting, so she would've been selecting breeds with high prey drive. The use of a shock collar for "training" would seem to confirm that. Pretty vile to shoot a dog for acting out its natural instincts based on behavior you as the owner were encouraging.
