Drainage originating from within the equine ear is rare. When it does happen, it is usually caused by a foreign body like a foxtail or bur that has caused inflammation and infection within the external ear canal.

Ear ticks can also cause inflammation and infection resulting in drainage or excessive accumulation of waxy material in the ear. Usually, in either case, there are other signs of distress or discomfort.

WHAT TO DO

Assess your horse’s general health with the Whole Horse Exam (WHE), paying particular attention to other possible abnormalities – head shaking, cocking of the head or ear, or wobbliness, and changes in appetite and attitude.

If your horse yields to pressure on the halter and will allow you to examine their ear, you may be able to gently examine the ear canal using a headlight and gently pulling the hairs away with your fingertips. Share your findings and concerns with your vet.

WHAT YOUR VET DOES

Following a general physical exam, your vet will careful assess the ear and ear canal. Sedation for a proper ear examination may be necessary. In some cases, a cause is not found. In that case, symptomatic treatment might be needed for a time before more aggressive and expensive diagnostics are employed.

What Not To Do

Do not insert anything into your horse's ear. Do not struggle with your horse to look into their ear.
