You know looking at pictures of our horses, I have to retract a statement - I don't think the legs are too thin for any breed. This is a picture of one of our Friesian mares (a light draft breed with a lot of bone) and look at how thin her legs are compared to her body. (the foal is a Friesian too - just one of the rare chestnuts that pop up from time to time).
