I am so sorry for your loss. I know exactly what you are going through as I lost my beloved stallion Cody when he was only 4, my vet and I did all we could but lost him a week after he became sick. I know no one will ever replace Royal but as the years go by the pain of his loss is lessened. "Think of him as living in the hearts of those he touched, for nothing loved is ever lost and he was loved so much."
