Pasos are very lively and proud horses. They are a horseman's horse. They are very smart. If they like and respect you, they will work their little butts off for you. While they are a bit hot, they are generally very easy to manage, but you need their respect.
I've found they don't do well with riders that like slow ploddy rides and who worry when the horse shows a bit of go. They do not like riders who continually pull on their heads to keep them slow.
On the other hand, for a confident rider, even if not too skilled, they can provide a lively ride. Because they are proud and funloving critters, they are great when you engage their minds and give them things to do, both in your interaction on the ground and under saddle. They are not flighty and run away types like many Thoroughbreds and Arabians. Some are a bit hot but if you set boundaries and give them a job to do, they do great.
If you are a rider who likes a bit of flair in a horse and who can laugh when the horse puts on some airs and graces, then a Paso will enjoy you and you will enjoy him.
