Vaulting Horse Requirements
The vaulting horse is an important member of the team. There are few specific requirements for a vaulting horse (at least six years old and either a mare or gelding), and horses of almost any breed have been and are being used quite successfully. Due to the requirements to support a team (with up to three vaulters at once), there is a tendency to use larger horses.

Perhaps the two most important attributes of a vaulting horse are temperament, and an even gait (some would say temperament...and temperament). The need for an "even gait" is fairly obvious, but even more vital is an ability for the horse to accept a variety of fairly strange behavior (sitting on the neck, for example) without changing gait or otherwise putting up a fuss. Vaulting horses are perhaps the most laid-back of animals, and the stories about them are legend.
