Horse asthma, also known as recurrent airway obstruction (RAO) or equine heaves, is a common respiratory condition that affects horses, particularly older ones. It is characterized by inflammation of the airways, leading to coughing, nasal discharge, and difficulty breathing. The condition often worsens in response to environmental factors, such as dust, mold, and pollen, which can be prevalent in stable environments or during certain seasons. Understanding the causes, symptoms, and treatment options for horse asthma is crucial for horse owners and caretakers.
