The registry got back to me and said they found a horse that matched up to my horse including the tattoo number, from 1994! That would make him 17 years old! Holy cow, we had no idea my horse was so old! And I was just getting into eventing with him.
My question is how would you guys react if you found out your horse was older, or younger than you had thought? And if anyone has some advice on how to keep my horse in tip top shape through his aging that would be nice, he already has a weak back that we've been significantly working on strengthening and making good progress, but we certainly don't want him to develop a sway back, joint problems, etc! We were never prepared to own an older horse, we always thought he was only 13-14!
