Scientific Name: Equus ferus caballus
Miniature horses are horses defined by their small height.
Depending on the particular breed registry involved, the height of these horses is usually less than 34–38 inches as measured at the last hairs of the mane, which are found at the withers.
Miniature horses are generally bred to be friendly and to interact well with people.
They also can be trained as service animals for disabled people.
The smallest known mini horse is Thumbelina, a sorrel brown mare who measures just 17 inches tall!
