Asthma in horses, often referred to as Equine Asthma Syndrome (EAS), is a common respiratory condition that affects the airways of horses and can have a significant impact on their overall health and performance. The condition can range from mild to severe, and it is characterized by inflammation of the airways, which can lead to coughing, difficulty breathing, and a decreased exercise tolerance. Understanding the causes, symptoms, and treatment options for asthma in horses is crucial for horse owners and caretakers to ensure the well-being of their equine companions.
