Dog Ear Infections: Causes, Treatment & Prevention in Australia
Ear infections are one of the most common vet visits in Australia. Here's how to spot, treat, and prevent them before they become serious.
Ear infections are caused by yeast, bacteria, or ear mites — signs include head shaking, bad smell, and discharge. See a vet within 48 hours.
Australian humidity and swimming create the perfect environment for ear infections; floppy-eared breeds (Cocker Spaniels, Labradors) are most prone
Weekly ear cleaning and drying after swimming can reduce infection risk by 50–70%

- 💧Moisture is the #1 trigger
- 🐕Floppy ears = highest risk
- ⏰See vet within 48 hours of signs
- 🛡️Weekly cleaning prevents most infections
Ear infections are painful, quick to worsen, and if left untreated can cause permanent hearing damage. The good news: most are entirely preventable with a 5-minute weekly routine.

What Causes Ear Infections in Australian Dogs?
Heat + humidity = perfect infection environment
Australia's warm, humid climate creates ideal conditions for yeast and bacteria to multiply. Coastal summers, beach trips, and backyard swimming all increase risk. Water sitting in the ear canal for even 24–48 hours can trigger an infection in susceptible dogs.
Highest-Risk Breeds
| Breed | Why they're prone | Prevention priority |
|---|---|---|
| Cocker Spaniel | Long floppy ears trap moisture and reduce airflow | ⚠️ Weekly cleaning minimum |
| Labrador Retriever | Love swimming — water enters ear canal constantly | ⚠️ Dry after every swim |
| Cavalier King Charles | Small, narrow ear canals, folded structure | ⚠️ Weekly cleaning |
| Basset Hound | Extremely long ears drag on ground, collect debris | ⚠️ Daily inspection |
| Dachshund | L-shaped ear canal traps debris and moisture | ⚠️ Weekly cleaning |
| Golden Retriever | Dense coat + love of water = chronic risk | ⚠️ Post-swim routine |
Spot an Infection Early — Symptom Guide
| Sign | What it means | Action needed |
|---|---|---|
| Head shaking | Discomfort or itching in ear canal | Inspect the ear; clean if wet |
| Scratching or pawing at ears | Itching or early pain | Inspect and clean; see vet if persistent |
| Yeasty or musty smell | Yeast overgrowth beginning | See vet within 48 hours |
| Brown or yellow discharge | Active infection | See vet — needs prescription drops |
| Redness or swelling inside | Acute inflammation | See vet within 24 hours |
| Dark crusty discharge | Likely ear mites | See vet — all pets need treatment |
| Head tilting to one side | Inner ear involvement | Emergency vet — serious condition |
Don't wait — ear infections worsen fast in Australian heat
Any odour, discharge, or scratching that persists more than 24 hours warrants a vet visit. Untreated infections can damage the middle and inner ear, causing permanent hearing loss and requiring surgery. Early treatment = much lower cost and faster recovery.
The Weekly Ear Cleaning Routine
Takes 5 minutes — prevents most infections entirely
Inspect first
Look inside both ears before cleaning. Note any odour, redness, discharge, or unusual moisture. If you see pus, redness, or smell anything foul — see the vet before cleaning, as cleaning can spread infection deeper.
Fill with ear cleaner and massage
Use a ceruminolytic cleaner (like Virbac Epi-Otic). Fill the ear canal generously, fold the ear over, and gently massage the ear base for 30 seconds. You'll hear a squelching sound — this is the cleaner breaking down wax and debris.
Let them shake, then wipe
Allow your dog to shake their head — stand back and do this outside or in a bathroom. Then fold the ear back and wipe away visible debris with a cotton ball. Never insert cotton buds into the canal — only clean what you can see.
Virbac Epi-Otic Ear Cleaning Solution
The most widely used vet-recommended ear cleaner in Australia. Ceruminolytic formula dissolves earwax and debris without irritation. Use weekly for prevention and as part of infection treatment.
Dog Ear Cleaning Wipes
Pre-moistened alcohol-free wipes for quick daily maintenance and post-swim drying. Easy to use on dogs who resist liquid ear cleaners.
Dry ears after every swim — this alone prevents most infections
After swimming or bathing, gently tilt your dog's head to drain excess water, then use cotton balls or ear wipes to dry the visible ear canal. Don't insert deeply — just dry what you can see and reach. Water left for 24–48 hours is enough to trigger infection.
How Vets Treat Ear Infections
| Type | Medication | Duration |
|---|---|---|
| Yeast infection | Antifungal ear drops (miconazole or clotrimazole) | 7–14 days |
| Bacterial infection | Antibiotic ear drops or oral antibiotics | 10–14 days |
| Ear mites | Acaricide drops — all pets in household treated | 2–3 weeks |
| Allergy-driven | Antihistamines + anti-inflammatory drops + allergy management | Ongoing management |
Never use human ear drops on your dog
Human ear drops are not formulated for dogs and can be toxic, especially if the eardrum is perforated. A perforated eardrum (from severe infection) changes what can safely be applied. Always use vet-prescribed or vet-approved dog-specific ear products only.
Recurring Infections — When to Investigate Deeper
If your dog gets more than 2–3 ear infections per year despite regular cleaning, an underlying cause needs investigation.
