External Ear Infections

Synonyms: Otitis Externa

External ear infections are not common in horses. A dark waxy material is normally found in the external ear canal of horses, while pus is not. Occasionally, however, a horse does have a significant infection marked by obvious drainage from the ear in combination with head tilt or head shaking.

Infection is often a consequence of some other underlying disorder such as an ear foreign body, tumor, ear ticks or ear mites.
