Sorry for your loss. He was a handsome boy, for sure.
My family lost our first mare (we had her just under 20 years) last fall. For Christmas I bought myself, my sister and Mum a necklace with a heart locket (with some of her mane) and a little horse shoe. I didn't think I'd own a horse again it hurt so bad (and her death was sudden), but I came to realize it only hurt so bad because of all the love and wonderful memories she gave me and my family and I didn't want to miss out having those wonderful moments with another lovely horse, which I now have.
