Yesterday I found out she was just put down. I later found out the reason was that, and I quote, "She had Cushing's and we didn't know, then she foundered and colicked at the same time." ...What? First off, is it common to just flat out not know a horse has Cushing's? And how much were they ignoring the horse that they didn't realize she was foundering until she colicked? I looked up the symptoms of Cushing's and at least when I was there I saw none of them.
Can you help me figure this out? I feel awful and all, I just want to know why this possibly happened and if I could have helped actually notice problems by not leaving the barn.
ETA: Sorry if I explained anything badly. Ask me to clarify if you're not sure.
