Any one have a similar situation with horse euthanasia?

I've never heard os seen anything like that before. When I read your question and description it really made me shiver and shudder. That really does sound terrible, and if something like that happened to my horse I know I wouldn't forget it easily at all. I mostly want to say I understand completly why you asked this question and how you can't forget, and I can not imagine what that must have been like for you then and now, since I still own my first horse and she is still happy and healthy. I hope things get a little better for you, and you never have to see that kind of thing again.
