Is it true that a horse with small eyes is bad temperd horse?

The size of a horse's eyes is not an accurate indicator of its temperament. A horse's temperament is influenced by various factors, including breed, genetics, training, and individual experiences. Horses with small eyes can be just as good-natured and well-tempered as horses with large eyes. It is important to assess a horse's temperament through its behavior and interactions rather than relying on physical characteristics such as eye size.
