I don't know. I think he clearly looks juvenile still in the picture, not an 8 year old horse. But there's a lot that doesn't make sense about what she did.
You should post something about this on the horse forum. There's a lot of those folks that look at online ads, some for real money, I guess one shouldn't assume there's real horses behind the ads unless they go look.
I thought about posting on horse.com, guess I'll see what I can find out first.
