That description REALLY sounds like it's a match, when you look at the pics...the markings are pretty darn detailed! I'd say they've got the right horse! But if the breeders can "flub" the age and all, who's to say that they couldn't lie about the age to the tune of a couple years? I know it's far less likely, but who knows, maybe he is only 18?
I think regardless, he looks great for a teenager!
I would never have guessed him at older than 9 or 10 to be honest!
