Equine allergies happen when the immune system overreacts in response to a substance. They can happen any time of the year as well due to different changes in the horse’s environment.

Types of Allergies

  • Contact/dermatology allergies

  • Insect allergies

  • Respiratory allergies

  • Food allergies

Symptoms of Allergies

  • Hives

  • Itching (mild to severe)

  • Watery, swollen, red, draining eyes

  • Runny nasal discharge

  • Coughing

  • Wheezing

  • Labored breathing

  • Tail rubbing

Common Causes of Allergies

  • Feed changes (some horses are allergic to certain types of feed)

  • Pollen

  • Dust

  • Mold spores

  • Bedding

  • Plants

  • Flies

  • Bee’s

  • Mosquitos

  • Fly spray


Treatment can vary due to difficulty in finding exactly what the horse is having an allergic reaction to. Some treatment options are as follows:

  • Removal of allergen if possible

  • Steroids

  • Corticosteroids

  • Allergy testing (offered as a blood test through our clinic, please call to schedule)


Often its difficult to pinpoint the allergen to blame for equine allergies and sometimes things cannot be prevented such as pollen in the air. However, there are measures you can take to help prevent an allergy flare up in your horse.

  • Slowly introduce changes in the environment such as a new hay, shavings, ect and monitor for changes over time.

  • Know the symptoms to look for when your horse has an allergy

  • Eyes: Use fly masks to keep the flies out of your horses’ eyes

  • Dust: wet down the hay

  • Try different bedding options

  • Supplements: For example, Platinum Performance offers a product call platinum skin and allergy (Please call or email to order Platinum products)

*Contact your local veterinarian if you think your horse may be having an allergic reaction
