A veterinarian finding a growth in a dog’s ear does not automatically mean it is a harmless polyp. Inflammatory ear polyps are much more common in cats and rare in dogs. A canine ear mass may represent inflammatory tissue, a cyst, or a benign or malignant tumor. The appearance alone may not reveal which it is.
Signs owners might notice
Chronic ear discharge, odor, scratching, head shaking, repeated ear infections, or discomfort when the head is touched can point to a problem inside the ear canal. A mass may also interfere with drainage and make inflammation difficult to control. Head tilt, loss of balance, facial weakness, or sudden severe pain warrants prompt examination because deeper ear structures can be affected.
How the veterinarian investigates
The first step is usually an ear examination with an otoscope, sometimes under sedation when pain or swelling prevents a good view. The clinician may examine ear discharge under a microscope and recommend imaging or tissue sampling. A biopsy can help distinguish a true inflammatory growth from a tumor; the appropriate procedure depends on its location and extent.
Why medicines do not solve every ear mass
Antibiotics or anti-inflammatory medicine may help associated infection or inflammation but may not remove an underlying mass. In some cases surgery or referral to a veterinary dermatologist or surgeon is appropriate. Do not try to pull or puncture a growth yourself, and do not put leftover ear drops into a painful ear without knowing whether the eardrum is intact.
What to ask about follow-up
Ask whether the growth has been identified by pathology, what the options are for removal, and how likely it is to recur. Keep records of previous ear treatments and their effects. New balance problems or marked discomfort should be assessed promptly rather than managed as a routine itchy ear.
