OMG!!!!!!!! I'm sooooooo sorry to both you and your friend :'( that would have been sooo hard to watch. You are such a good friend to stay with her.
I watched a horse die a last year, we were at an event and at night the horse was put alone in the round yard near the bush with 2 metre high fences and he got spooked by a kangaroo and jumped out. He cleared the fence and then slipped. He broke his back leg and pelvis and he took off galloping to all the other horses and went down thrashing on a ponies yard that jumped out over my head as I tried to grab it. It died 10 minutes later from internal injuries and stress. It was the most horrible thing I ever saw in my life! So I know how you feel. Seeing a horse die when you love horses soo much is heart breaking even if you don't know the horse.
Go spend as much time cuddling your horse and let her know that your with her, because she had to watch it too.
Send mine, ozzie's and marco's love to your horse, yourself and nicki and her son :'(
This is heartbreaking. Unfortunately I know the feeling the owner is feeling, since I too lost a horse in a freak accident. I was devastated for months and months. It will be almost 3 years and I still miss him terribly. I try to remember that things-no matter how traumatic-always happen for a reason and most the time we will never know that reason. I am so very sorry to the owner as well as everyone who had to witness this terrible event.
I can't even imagine how heartbreaking that would be. The first horse I lost was 24 years old. He colicked and we couldn't save him and had to put him down. It was probably 2 years before I could talk about him without crying. I get wayyyy too attached to my horses.
