It is very difficult to train a wild horse, as they cannot adapt to change in their habitats. They can just be taught basic gait.
Temperament:
They are shy creatures and may run away as a defense measure. However, they may become violent if their family is threatened.
Child Friendly:
They are indifferent to children.
Behavior:
They are untrained beasts and hence their behavior is unpredictable. It is better to view them from a distance.
Riding Ease:
They are fast runners, but not good to ride on.
Uses:
They have a place in myth and legend as horses of knights and heroes. They can be trained to work in circuses.
Wild Horses - Horse Breed Concerns
Health Issues:
Being adapted to forest life, they have built resistance against many diseases. In captivity, they may suffer from infections, listlessness and diseases of the alimentary canal.
Feeding:
Wild horses are not meant to be fed by humans. They can subsist and thrive on natural vegetation.
Outfitting:
Outfitting is not applicable to wild horses. Minimum saddle and bridle is enough.
Wild Horses - How to Choose a Horse Breed
What to Look for:
Look for a horse with a steady temperament so that it would not be aggressive in the future.
What you will Need:
A wild horse would require much free space, like that at a ranch. Synthetic food must be avoided and outfitting needs are minimal.
