Which of the following is an indicator of an abnormal ear condition in dogs?

• A. Normal hearing sensitivity
• B. Excessive amounts of wax or discharge
• C. Clean ear canal without odor
• D. No flaking or itching

Answer: (B)

Abnormal ear conditions in dogs are most clearly signaled by excessive amounts of wax or discharge. A small amount of wax is normal and protective, but when production ramps up or the ear drains more than usual, it points to a problem such as infection (otitis externa), allergies, or ear mites. This extra material is often accompanied by other symptoms like odor, redness, or irritation, and may cause the dog to shake its head or scratch at the ear.

In contrast, a clean ear canal without odor, normal hearing sensitivity, and no flaking or itching all point toward healthy ears. Those signs suggest there isn’t an active problem in the ear canal. If you observe excess wax or discharge, it’s wise to have the dog examined by a veterinarian to determine the cause and appropriate treatment.
