What do Arabian horses look like?

Well the original old type of Arabian had a kind of 'ewe' neck where the bottom was longer and/or stuck out farther than what was considered acceptable by breeders. The horses also tended to carry their heads and necks very upright and sometimes held back towards their withers. Modern Arabians now have a more graceful neck where it is highly arched and carried either forward, level or straight depending on the horse.
