Which of the following is a sign of good health in a horse?

Bright eyes in a horse are a strong indicator of good health. When a horse has bright, clear eyes, it generally indicates that the animal is alert, active, and feeling well. Healthy horses typically exhibit lively expressions, and their eyes will appear clear and shining, reflecting wellness and vigor. In contrast, characteristics like a dull coat, a sad demeanor, or a high temperature can signal various health issues or stress, suggesting that the horse may not be in optimal condition. A dull coat often indicates poor nutrition or health problems, while a sad demeanor can reflect pain or distress. A high temperature could indicate infection or illness. Therefore, the presence of bright eyes is a straightforward and positive sign that a horse is in good health.
