Otitis Externa is inflammation of the ear canal, commonly caused by yeast (Malassezia) or bacteria. It is rarely a primary disease; almost all ear infections are secondary to allergies (food/environmental) or moisture accumulation (swimming).
This condition requires veterinary attention.
If your animal shows the Key or Common signs listed, please visit a clinic immediately.
Report Case / Get HelpEar infections are generally not contagious. However, ear mites (Otodectes), which can cause infection, are highly contagious among pets.
The ear becomes red, itchy, and produces wax/discharge. Chronic inflammation causes the ear canal to thicken and narrow (stenosis), making treatment difficult and potentially leading to middle ear infection.
Cytology (examining a swab under a microscope) identifies if the cause is yeast, bacteria, or mites. The Vet examines the ear drum (tympanic membrane) with an otoscope.
Treatment involves deep cleaning followed by topical drops (antibiotic/antifungal/steroid combo). Addressing the underlying allergy is crucial to prevent recurrence.
Routine ear cleaning after baths or swimming helps. Managing underlying allergies is the primary long-term prevention strategy.
Excellent for acute cases. Chronic cases can be frustrating and may require surgery (TECA) if the ear canal becomes permanently calcified.
