"The hot bloods, such as Arabs and Thoroughbreds, have slim bodies with slender legs, and cold bloods, such as draft horses, are stocky with heavier bones. Measurements of the diameter of the leg bones show that the most flighty animals have thinner bones. No one should abuse any horse regardless of whether the abuse works or not. I've noticed that rough trainers prefer to work with horses that are calmer and less reactive." ~ Dr. Temple Grandin, "Animals Make Us Human"
