First of all was my surprise when my Vet said "He isn't in the 20-21 age range. He's more like mid twenties, 24-25." Okay so add 3-5 years on my horses age. =\ Yet she was even surprised by his health. She says he is in great condition, she says the way he moves and looks like a teenager, but his teeth say otherwise. So I have a healthy elderly horse. No back/shoulder issues, (So I guess I'm good on the saddle fitting)
She says that for his feet he isn't lame off of farrier issues, she agrees that he is tender from his sidebone/ringbone which she found in both front legs. She said that it is so slight that it is hard to notice. She said that x-rays would be a waste of money due to his age (Not looking at him as a prospect for high level work) and it wasn't sever enough to be worried about it affecting his joints. She also said he looks to be developing some arthritis in a back hock. Once again, she says for his age he is doing great. She repeated that my farrier is the best in the area and knows his stuff.
I am pretty much to play it by ear for riding to see what he can/can't handle. Her guess is that he should be good for jumping up to 2'6", but he will let me know if he can't. She also suggested taking it more of an easy on him than younger horses (longer recovery times...) She suggests bute for bad days and to keep him on joint supplements.
Overall, keep enjoying him but let him tell you when it is too much.
