I first looked at this horse and thought she was an Akhal Teke.. but was not sure since I had no idea what part of the world she was posted from. I also thought maybe she was a light boned Thoroughbred.
Yes, for the breed she has acceptable bone.
However, I look at horses from the point of view of "how many years of daily hard work can this horse take and stand up? Will she be sound and working at age 20?"
I know Arabians, with light bone (I am NOT a fan of the breed at ALL) often do exactly that.. work into their 20's and do so soundly. There are Thoroughbreds that are the same way (and I love a good Thoroughbred.. but I still want good bone!).
My point is that with some horses and some breeds, the light bone is not so much an issue.. and it may be tied to the way the horse is used.
