Causes of Horse Allergies

Many different items commonly found in any horse’s environment can cause allergies. Stabled horses are engulfed in dust, mold spores and other allergens on a daily basis.


Usually a horse can fight off these allergens with a healthy immune system, but not in every circumstance. A recent landmark study found that 88% of horses were suffering from the respiratory allergy Inflammatory Airway Disease*


How does it show itself?

Signs include coughing, nasal discharge, increased respiratory rate, increased respiratory effort, flaring of the nostrils, respiratory noise at rest or during exercise, poor performance.
