tedj01:I started doing rigging our horses' bridles to break, after one got a leg hung up in reins when tied to a barb wire fence and was fighting it badly. He was cutting himself and about to get hung up in the barb wire. He had completely lost it and was screaming hideously. I had to go in with a pocket knife and to cut him free. It was a close call as he pinned me against the fence also. When pinned against the fence with the horse screaming in my ear, I almost had to decide whether to go ahead and cut horse's throat. It was getting that hairy. He had two posts almost out of the ground and I was concerned he would knock us both to the ground and roll us up in the wire. I was able to cut him free. Neither of us got cut too bad; though I did have to walk home as he ran free. Then I got to do first aid to horse, me, and fence.
Back to topic, no it is not something anyone wants to go thru. Lots of people cause these situations by having dog collars too loose. I have had to cut dogs off fences where they tried to jump the fence and get their collars hung. Thats fun to trying to cut a dog loose thats doing its damndest to bite you. That was also the problem with the horse above, I did not tie him up properly.
Oh by the way for those who understand, it was a glass eyed horse. Hmmm, kinda reminds me of panicked divers though their kicks and teeth are not as strong.
Had the same experience years ago trying to seperate a horse and a barb wire fense - mine didnt turn out as well as we lost the horse.
