What is characteristic of pig eyes in horses?

Pig eyes in horses are characterized by being small and set deep in the head. This specific structure can give the horse a unique appearance compared to breeds with different eye characteristics. The placement of the eyes affects the horse’s field of vision and overall facial structure, which can be quite distinct in certain breeds.

The other characteristics mentioned—such as being large and prominent, having a bright and alert appearance, or bulging outwards—do not accurately describe pig eyes in horses. Each of these features typically aligns more closely with other eye types that may be observed in various horse breeds, where the eyes are either larger, more visually expressive, or positioned differently relative to the skull. Understanding these variations is essential for assessing equine conformation and health.
