My horse grew 5 inches AFTER she turned 3. Draft crosses are notoriously late bloomers, so don't count out his height yet.
Also, no such thing as 14.5 hands. It goes 14.1, 14.2, 14.3, and then 15 hands. The .1 or whatever is how many inches past 14 hands, and since there's only 4" in one hand, then you can't have 14.5 h
He's probably going to be an extremely stocky horse.
Well, that's a given
. Half drafts are rarely "lithe" and most Morgans aren't exactly spindly on their own, lol (unless they're those weird looking show Morgans, that look more like Arabs...).
