So very sorry for your loss. Thinking of you at such a hard time. I lost one of my favorite mares to a freak condition last year (a tear in her aorta) I know how you feel. It just took the wind right out of my sails. Hang in there.
I am so sorry for your loss, we know how you feel, last week we found one bitten by a snake but it was too late to do anything but put her down. It makes you sick when you know that there is noting you can do. It hurts a lot
