Knowing he has reach on that age just shows how you take good care of him! And for sure he couldn't ask for more than what you've giving to him! He is indeed one gorgeous horse! It's sad but may he Rest in Peace! My condolences to you!
Indeed,although I would say that early preparations may not really cover the actual event if it happens at least you did your part! It's hard but it's part of life as we will all be going there!
