This was a well planned, well thought out breeding, and the foal was going to be born to someone who wanted it and had plans for its future.
When the mare went into labor, the baby presented crown first. They took the mare to the closest vet hospital, but the foal suffocated before they could get it out, and the mare had extensive nerve damage and had to be euthed.
My friend is devastated and full of guilt. She keeps saying if she hadn't bred the horse, the mare wouldn't be dead now. I can only offer sympathy and a shoulder upon which to cry.
It was a needless, senseless death, but one that every mare owner has to be prepared to face if they want to breed.
