How to prevent, recognize, and treat ear infections in dogs
Ear infections are common and uncomfortable for dogs, but many can be prevented, caught early, and treated effectively at home or with your veterinarian’s help. This guide gives clear, practical steps to reduce risk, recognize signs, and manage treatment so your dog stays comfortable and healthy.
Step 1: Inspect ears weekly
Look inside both ears once a week using good light for 30–60 seconds. Check for redness, discharge, swelling, or a strong odor; catching changes early lets you act before an infection worsens.

Step 2: Keep ears dry after water
Dry your dog’s ears within 5–15 minutes after baths, swimming, or rainy walks using a soft towel and gentle pressure; for breeds with floppy ears, use a cotton ball in the outer ear for up to 10 minutes. Moisture encourages yeast and bacteria growth, so quick drying lowers infection risk.

Step 3: Clean ears safely monthly
Use a vet-recommended ear cleaner once every 2–4 weeks for dogs prone to wax buildup; apply 1–2 mL for small dogs or 5–10 mL for large dogs, massage the base for 20–30 seconds, then let your dog shake and wipe with a clean cloth. Regular, gentle cleaning removes debris and prevents blockages that trap microbes.

Step 4: Trim hair near ear canals
Trim excess hair around the ear opening every 4–8 weeks to improve airflow, or have a professional groomer do it for long-coated breeds. Better ventilation reduces humidity in the canal and lowers infection chances.

Step 5: Watch for behavioral signs daily
Observe your dog each day for ear-related behaviors like head shaking, ear scratching more than 5 times per hour, or sudden ear sensitivity during petting. Behavioral changes often appear before visible symptoms, so prompt attention prevents escalation.

Step 6: Check for physical symptoms
Perform a gentle physical check once weekly: look for redness, dark brown or green discharge, scabs, or a smell; gently press near the ear base to see if your dog flinches. These findings suggest infection and warrant veterinary evaluation within 48 hours.

Step 7: Start vet-guided treatment
If you suspect infection, contact your vet and bring a sample or allow cytology; follow prescribed treatment exactly—apply topical meds 2–3 times daily for the full 7–14 days and give oral meds as directed. Incomplete treatment leads to recurrence and resistant infections.

Step 8: Follow-up and prevention plan
Schedule a recheck 7–14 days after starting treatment or sooner if symptoms worsen; adjust cleaning routine and allergy management based on vet advice. A documented prevention plan reduces future infections and improves long-term ear health.

- For floppy-eared breeds, lift ears occasionally to air them for 10–15 minutes daily.
- Use a soft cotton ball rather than cotton swabs; swabs can push debris deeper into the canal.
- Note any food changes or seasonal flares—food allergies or pollen often trigger recurrent infections.
- Keep nails trimmed to avoid accidental ear scratches during scratching episodes.
- Record dates of cleaning and treatments in a simple log to track patterns and recurrence.
- If your dog resists ear care, try short 30–60 second sessions paired with a small treat to build tolerance.
- Do not insert cotton swabs or any object deep into the ear canal—this can damage the eardrum.
- Avoid home remedies like hydrogen peroxide or undiluted vinegar without veterinary approval; they can irritate or burn inflamed tissue.
- If you see bleeding, severe pain, facial paralysis, or the dog stops eating, seek emergency veterinary care immediately.
