Not talking about height.
There's a 2(or 3)yo filly I've been offered. Her owners have a breedng herd and she somehow got misplaced as a foal- they didn't know she existed until now! They did halter train her and everything, so she's almost up to snuff. I'm looking for a mid level event prospect, and right now this filly is perfect. She's pretty much textbook when it comes to proper angles and everthing, she's 15hh right now, and probably matureing at 16 so also my perfect size. Only thing is she's a little downhill, but she does look like she's still growing.
So my question:
How much "coarser" will a 2 or 3 yo get?
Right now she's perfect, heavier then a tb but lighter then any of the draft Xs around here. A lighter draft cross if you will. I'm worried though that if she gets much bigger bones she won't be able to be truely competitive.
I also know that the spine is one of the last things to stop growing, do 2/3yos get longer in the back too? She's be ok if she was a few inches longer so that doesn't worry me.
And for vanities sake, do their heads change shape? She's got such a nice head right now I would hate for that to change too XD
Thanks in advance!
ETA: She does have large feet- don't know if that means anything
