We found her in the field Sunday morning, she had been fine Saturday night. Vet thinks it was most probably an aneurysm & stroke, she was only 12. It's so awful without her, her two field mates miss her, they seem so lost.
How absolutely awful. I saw the thread you are referring to. Two mares of similar age. It must be a tragic but rare occurance. OP I cannot imagne how you must feel.
