Naturally, asymmetries can be found in humans as well as horses. When it comes to horses, the typical forms of structural asymmetry are in bone size, muscular development and hoof dimensions. It has been noted by Sarah Jane Hobbs, et al, in their recently-published study that about 5% of Dutch Warmbloods have uneven dorsal hoof wall angles in the front limbs. The development of this unevenness can often be attributed to horses favoring one side or the other, often termed sidedness.
