This might seem like a dumb question.
I understand in concept what the difference is between light in bone and fine boned. To me fine boned means just more petite, but the bone is still dense and strong. Light in bone means less dense in bone and more prone to injury.
My question is, when you look at a horse, how do you tell the difference if they are just fine boned, or light in bone? Forgive me if this seems like an obvious question, but I'm curious to know.
