going to disagree with some comments made.
1. this mare does not have a long back, if you divide her up in thirds she's almost perfect, if anything her hip is longer. back is perfect
2. she's not posty. her hock angle is very good and in one pic she's standing under herself but in the others if you drop a line from her rump to the ground, her hock and pasterns hit exactly as they are supposed.
This mare is put together very, very well. She needs a trim and in the first photo her pasterns look too sloped, but in others they are clearly fine. She is super refined, beautiful throatlatch, clean neck tie in, strongly muscled topline and hip, good bone and attractive head (for an appy)
I think she is def. breeding quality and she's certainly fit enough to have one more if you choose to do that. Love her!
