A week ago I tragically lost my 1/2 Arabian mare. She became tangled in the polyrope electric fencing and severly injured her back leg. I'm not sure of the details as I was out of town at the time, and my parents were there to see her and make the call of whether to euthanize her, which they did. They could not tell if it was a break or not, but she was standing directly on the fetlock joint and would not stand on the hoof even when they tried to put it on the ground for her. Also she was in such shock and immense pain that she could not be trailered to the vet clinic. My parents decided that the best option was to euthanize because no matter what the technical injury, it seemed to be irreparable and she was in a lot of pain. Also she was 22, so she would not have easily healed. Again, I am unsure of what happened in the accident as my parents did not actually see it, and also I didn't want to press for details as it was painful for all of us.
Before this happened, we were going to move my other horse, a purebred Arab gelding to this boarding facility. Of course now, I don't know if I want him to move there. I don't know if her fencing is in reality unsafe, or if it was just a freak accident. I haven't found any great evidence that the fencing is unsafe, but at the same time I would never forgive myself if I moved my other horse there, only to have the same thing happen.
The vet said that she considered the fencing to be safe, but at the same time if she's the vet on call for the facility, she's likely to be friendly with the owner and perhaps somewhat biased.
It's polyrope electrified fencing with about 5 ropes, and approximately 6 inches apart. I'd really appreciate any opinions that anyone has.
