If the haunches of a young horse are higher than his withers does this mean he is still growing and does this give an indication of his final height?

he may be still growing. but it IS possible for a horse to be 'downhill' (withers lower than haunches) or 'uphill' (withers higher than haunches.) uphill horses sometimes Excel at jumping because it makes it a little easier to jump. but of course it is subjective. my horse is downhill and she's a great jumper!
