What clinical signs are observed in a horse with laryngeal paralysis?

In a horse with laryngeal paralysis, the clinical signs primarily arise from the impaired function of the laryngeal muscles, which can affect airflow during normal breathing, especially during exercise. Coughing and exercise intolerance are significant indicators of this condition.

When laryngeal function is compromised, the horse may struggle to breathe effectively during exertion, leading to a reduced ability to perform physically and increased respiratory noise. Coughing can also occur as the horse attempts to clear its airways, further indicating a problem with the respiratory tract.

These symptoms are vital to recognize, particularly in athletic horses, as they can directly impact performance and overall health. Understanding these signs helps veterinarians diagnose laryngeal paralysis and distinguish it from other conditions that may cause similar symptoms.
