I am so sorry for your loss. My sister, LostTitanic, used to own a Belgian cross and her name was Titanic. Own day she was playing in the pasture and the next my sister knew Titanic's leg snapped like a twig. The vet came and took some x-rays, that is when we found out that she had austeoperosis(don't know how to spell it). The vet had to put her to sleep and she was only nine years old. Freak accidents happen and I am very sorry for your loss. He truly was a beautiful stallion.
