Your horse's butt should fill out as he matures and you will also be able to increase his musle tone when he is older and you start to work him.

Well if that is true it is how mine turned out. We gelded him at 9mths (ish), he will be 4 in Aug. this year and is 16 hands but not real thick. Course his dady turned out huge thick and I gelded him at 4yrs but he is just as tall too so hey I guess ya never really know My boy is just finally growing into himself now, still a little more narrow than I like but he has sat all winter also so we will see what happens with some good fitting up!
