Cold Blood-large horses with a gentle disposition and placid style. Descendants of the ancient European breeds used for farming, hauling and other heavy work. Ex. Clydesdale, Shire, Haflinger 2. Warm Blood- warm bloods have smaller heads and bodies compared to draft horses, they also tend to be less excitable than hot blooded horses, good all around horses for riding and work. Ex. Lipizanner, standard bred, quarter horse 3. Hot blood- refers to temperament, as they tend to be fiery tempered. Hot blooded horses are known for their speed as they have lighter bodies Ex.Arabian, Thoroughbred,Akhi-Teke -top breeds in the world: -arabian –quarter horse- paint- miniature horse-thoroughbred -long eared breeds -mammoth ass-they are crossed to produce draft mules -standard donkey- crossed for driving mules and pets -miniature donkey -Mule(cross between a donkey and a horse)-sterile, body is more like a horse -wild horses: -Prezwalski -mustangs -sable island -basic equine gaits -walk-4 beat movement -trot-2 beat movement -canter-3 beat movement -gallop-4 beat movement(similar to the canter but the horse’s legs move at one time) -horses have what is considered a “stay”mechanism, a series of muscles and ligaments can “lock” the main joints into position.
