Curly horses are known for their mild temperament and generally good work ethic. They have a curly haired coat; however, some purebred curlies have no curl at all. They can be found in almost all colorings.

Curlies have tough bones and strong hooves and mainly stand between 14-16 hands. An interesting fact of curlies is that most people who are allergic to horses can generally handle curlies. They are considered to be hypoallergenic. Scientists believe that a protein is missing from their fur that causes reactions to happen; however, this fact has never officially been published.
