Jillybean - I hate to tell you this, but if your horse is 19 months old he is NOT going to grow 8 more inches. Horses reach 90% of their growth by one year.
The only reason I believe he still has a lot of growing to do is because I've measured from his fetlock to his elbow, which should be equidistant to between his elbow and withers, and he's still got a ways to grow to meet that. That method has never failed me yet for the size of a full grown horse. His rump is still distinctly higher than his withers as well, further evidence that he's not done. He does seem short for now, I agree, but those indicate he's still got some height left. I'm awful and estimating distances, so it might not be quite 8 inches, but he's still growing.

Cinny's - thanks for the picture! He's about the same as your girl, so it's comforting to know you don't have any issues. I'd say my boy rests his leg most of the time, and switches which leg he's resting on. He generally stands on both back feet with one foot in front of the other. Like I said, it mostly shows when we're working on standing square. I can ask him to shift his weight onto both feet then and they're fairly wide, just toed out.
PS - we're getting a camera/camcorder for Christmas, so then I will have some wonderful high def pictures to show haha. As for now, I can't offer much.
