Common Allergy Triggers
Insect bites (especially culicoides midges, causing sweet itch), pollen, mold in hay or bedding, and certain feed ingredients are among the most common allergy triggers in horses.
Recognizing an Allergic Reaction
Hives, itching, hair loss from rubbing, watery eyes, coughing, or swelling around the face can all signal an allergic response, ranging from mild to severe.
Diagnosis and Testing
A veterinarian can help narrow down triggers through elimination — adjusting turnout, bedding, or feed — and in some cases through allergy testing to guide treatment.
Treatment Options
Depending on severity, treatment may include antihistamines, corticosteroids, environmental management (fly control, dust-free bedding), or in ongoing cases, allergen-specific immunotherapy.
