Horses as a species are very spirited, have great power and possibilities for movement. Different breeds have different possibilities for types of movement.  Some breeds, for example Arabs and Hunter Jumpers, can move more easily with a vertical trajectory than Friesians or Clydsdales.  Friesians and Clydsdales move with a horizontal trajectory and have enormous power to pull.

Some horses are more magnificent in their form, showing the world their beauty and power.  In this way, these horses are extroverts.  They tend to have a wider forehead and well developed shoulders and hips.  Natural introverts (Arabs) tend to have a more narrow forehead, narrow set eyes and sleeker bodies.
