The early signs of RAO (or chronic pulmonary obstructive disease, summer pasture-associated obstructive pulmonary disease or heaves) are often missed in donkeys as they are not usually exercised and appear to have a relatively insensitive cough reflex. There is airway sensitivity to allergens found in inhaled organic dusts, which leads to an influx of neutrophils into the airways, accompanied by bronchospasm and mucus accumulation.
