Ear mites and an ear infection can look almost identical from the outside — the same head-shaking, scratching and dark ear gunk — but they are two different problems that need two different medicines. Ear mites are a contagious parasite (Otodectes cynotis) that lives in the ear canal, while a "dog ear infection" usually means an overgrowth of yeast or bacteria, a condition vets call otitis externa. The only reliable way to tell them apart is a quick ear swab your vet examines under a microscope — the wrong guess means the wrong medication. Once your vet has sorted out the cause and confirmed the eardrum is intact, the Pure Majesty Pets Dog Ear Cleaner (120 mL, A$43) keeps ears clean between visits — with free worldwide shipping to Australia, duties and GST prepaid.
Below are the differences you can spot at home, why they change the plan, what Australian owners should also rule out (yes, paralysis ticks), and when to see a vet. For the yeast-versus-bacteria side of the story, see our guide to yeast vs bacterial ear infections. When choosing a routine cleaner, use the ear cleaner comparison to compare current ingredients and directions; a cleaner is a separate choice from treatment for an infection.
Dog ear mites vs ear infection: at a glance
These clues tend to separate mites from a yeast or bacterial infection. Use them as a starting point, not a diagnosis — the two often occur together.
| Clue | Ear mites (Otodectes cynotis) | Ear infection (yeast/bacterial otitis) |
|---|---|---|
| Typical patient | Puppies, rescue or multi-pet homes, dogs living with cats | Adult dogs, allergy-prone breeds, floppy-eared or swimming dogs |
| Itch level | Intense, sudden, relentless scratching and head shaking | Moderate to severe, often builds over days to weeks |
| Discharge look | Dry, dark, crumbly — classically like coffee grounds | Waxy brown (yeast) or yellow-green and moist (bacterial) |
| Smell | Often faint unless a secondary infection is present | Noticeable — musty/yeasty or sharp and foul |
| Contagious? | Yes — spreads to other dogs and cats by contact | No — not passed pet to pet |
| One ear or both? | Usually both ears | One or both; allergy-driven cases are often bilateral |
| Australian seasonal pattern | No particular season | Often worse in humid Queensland and coastal NSW summers and during pollen season |
What are dog ear mites?
Otodectes cynotis is a tiny surface mite that lives and breeds inside the ear canal, feeding on skin debris and wax. It doesn't burrow; the whole egg-to-adult cycle takes about three to four weeks, all inside the ear.[1] Because it spreads by direct contact, mites are far more common in puppies, litters, shelters and multi-pet homes — and dogs living with an infested cat often catch them.[1] That makes them a real consideration for the many Australian families who adopt a puppy or rescue dog into a home that already has a cat.
The hallmark of mites is intense, out-of-nowhere itch. Dogs scratch and shake hard enough to bruise the ear flap, and the debris left behind is typically dry and dark, like coffee grounds. In one review of 100 dogs with ear inflammation, mites were the underlying primary cause in about 7% of cases — less common than allergies, but a classic trigger in younger dogs.[2] If scratching is part of the picture, the guide to itch-relief options helps you separate relief measures from the work of finding the trigger.

What is a dog ear infection?
A dog ear infection — otitis externa — is an overgrowth of organisms that normally live in small numbers on the skin, most often the yeast Malassezia pachydermatis or bacteria such as Staphylococcus and Pseudomonas.[2,3] These infections are usually secondary: allergies, swimming moisture, a narrow or hairy canal, or trapped wax change the ear's environment, and the warm, damp canal lets yeast or bacteria bloom. The WAVD consensus notes Malassezia is more common in tropical climates and warm, humid months[3] — familiar territory for dogs in Brisbane, Cairns or Darwin — and AVA's Vet Voice lists grass and plant allergens such as buffalo grass, kikuyu and Wandering Trad that commonly set off itchy skin and ears in Australian dogs. For the comparison criteria behind this choice, see Best Dog Food for Allergies and Yeast Infections in Australia (2026 Guide). For a closer look at the question raised here, read French Bulldog Skin Allergies: Why They're So Itchy.
The discharge tells a story. A waxy, brown, slightly greasy buildup with a musty odour points towards yeast; a moist, yellow-green discharge with a sharper smell suggests bacteria. Our guide to dog ear wax covers what each colour can and cannot tell you. Unlike mites, an infection isn't contagious — it reflects that dog's own skin and ear health. The separate guide, Why Does My Dog Smell Like Yeast? The Odour Map Vets Use (Australia), explains the choices in more detail.
Why the difference matters: cytology decides the medicine
Here is the crux: the two respond to completely different medications. Mites need a parasiticide that kills the mite and its eggs; yeast and bacteria need antifungal or antibacterial therapy. Pour an antifungal into a mite-packed ear and the mites keep breeding; use a mite product on a yeast infection and the yeast keeps growing. Guessing wastes time and lets the ear get worse. When reviewing your dog’s parasite-prevention plan, use the dewormer coverage guide to match the choice to the parasite rather than treating every digestive change alike.
That is why vets rely on ear cytology: a swab of the debris read under a microscope. Mites and their eggs are visible directly (a drop of mineral oil helps), while yeast and bacteria show up as distinctive shapes with the right stain.[1] This five-minute test is the most useful step in sorting out an itchy ear.
The overlap nobody mentions: mites often cause a secondary infection
Mites and infections aren't an either/or. As mites inflame the canal, they set up the conditions yeast and bacteria love — so secondary Staphylococcus and Malassezia infections are commonly found alongside an active mite problem.[1] A dog can have both at once, which is why clearing only the mites sometimes leaves a lingering, smelly ear that still needs antifungal or antibacterial care.
The Australian extra: rule out a paralysis tick
On the eastern seaboard, from North Queensland down to Victoria, a dog pawing at its ear or shaking its head may have a paralysis tick (Ixodes holocyclus) attached in or behind the ear. University of Queensland researchers found 73% of ticks on pets are found on the head and neck, and RSPCA Queensland notes tick numbers rise from October to March. RSPCA Australia recommends daily skin checks — run your fingers around and inside the ear flaps, the neck and the face. Hind-leg weakness, a change in bark, retching or drooling is an emergency: go to a vet straight away.
How each is managed
For mites, vets use proven parasiticides. Modern isoxazolines (afoxolaner, fluralaner, sarolaner) and macrocyclic lactones such as selamectin and imidacloprid–moxidectin are effective, and cleaning the ear before the medication is applied is recommended.[1,5] Because mites spread by contact, every dog and cat in the home must be treated at once, even those that seem fine — otherwise the mites bounce between pets.[1] Ask your vet which product suits your household; several of these actives also feature in the tick and flea products Australian owners already use. For time outdoors, the flea and tick treatment comparison helps you compare coverage and application choices when planning the dog’s parasite routine.
For an infection, the usual plan is a thorough clean followed by medicated drops matched to what cytology found — antifungal, antibacterial or both, sometimes with an anti-inflammatory.[4] Our step-by-step guide to dog ear yeast infection treatment walks through the options. If coughing is limiting a walk, raise that separately from the mobility or stamina question. Our respiratory supplement comparison explains this product category and its limits after the cause has been assessed.
Where Pure Majesty Pets fits
Gentle, regular cleaning supports either plan and helps keep the next flare away. The Pure Majesty Pets Dog Ear Cleaner is built for exactly that job: 0.2% salicylic acid to soften and break down wax, 10% Aloe ferox with panthenol (pro-vitamin B5) plus allantoin and phytosphingosine to soothe and support the ear's skin barrier, and natural cyclodextrin to trap odour instead of masking it. It is chlorhexidine-free, pH-balanced to 5.0–5.5 and comes in a 120 mL bottle for A$43. Compared with local flushes such as Dermcare Otoflush (125 mL, A$27.47), Virbac EpiOtic SIS (120 mL, A$23.95 RRP) or PAW Gentle Ear Cleaner (120 mL, A$28.87), you get a published, barrier-supporting formula delivered to your door with duties and GST prepaid. It is a hygiene product: it does not kill mites and never replaces a parasiticide or prescribed drops, and like any cleaner it must not go into an ear with a ruptured eardrum. If face care is part of the same grooming session, our guide to eye cleaners for routine debris and tear stains helps you choose a purpose-made option for routine cleaning around the eyes. For the comparison criteria behind this choice, see Dog Ear and Eye Cleaner in Australia: Why Routine Cleaning Saves You Money.
Because so many canine ear infections are yeast-driven, many owners also add inside-out support once the vet has cleared the primary problem. Pure Majesty Pets Yeast Drops (A$47) give 19 named actives — roughly 292 mg per 1 mL, including 45 mg caprylic acid, 45 mg MSM and a 20 mg S. boulardii postbiotic — added to food daily. Supportive care, not a replacement for parasiticides or prescribed medication: no supplement clears a mite infestation.
When to see your vet
Book an exam if your dog is in obvious pain or won't let you near the ear; if there is bleeding, ear-flap swelling (an aural haematoma) or a strong foul odour; if the head tilts, the eyes flick back and forth, or your dog seems off-balance (possible middle- or inner-ear involvement); if symptoms don't improve within a few days; or if infections keep returning. Ear disease can damage the eardrum, and some medications are unsafe if it's ruptured — another reason a professional should look first.
Common mistakes to avoid
- Medicating for mites without confirming them. Most itchy ears in adult dogs are infections, not mites — a swab avoids treating the wrong problem.
- Only treating the itchy pet. Mites are contagious; skipping other household animals guarantees reinfestation.
- Pouring in peroxide, alcohol, tea tree oil or undiluted vinegar. These sting inflamed skin and can worsen the damage.
- Using leftover or a friend's ear medication. The wrong drug — or the right one in a ruptured eardrum — can do real harm.
- Stopping early. Mite eggs and stubborn yeast outlast a couple of days — finish the full course.
Frequently asked questions
Can I see ear mites in my dog's ear?
Rarely. Adult mites are under half a millimetre, so you're far more likely to see the coffee-ground-like debris than the mites themselves. A vet may glimpse them through an otoscope, but confirmation comes from a swab under the microscope.
Do dog ear mites smell?
A simple mite infestation often has little odour. A strong musty or foul smell usually means yeast or bacteria have taken hold — a secondary infection that changes what the ear needs.
Can ear mites cause an ear infection?
Yes. Mites inflame the ear canal, creating the warm, irritated environment where yeast and bacteria overgrow. Secondary Staphylococcus and Malassezia infections are common alongside mites, so a dog can have both at once.
Are dog ear mites contagious to other pets or people?
Very contagious between dogs, cats and ferrets by direct contact, which is why every pet in the home should be treated together. Human cases happen but are rare; wash your hands after handling an affected pet.
How do vets tell mites and infections apart?
With ear cytology — a swab of the debris under a microscope. Mites and eggs are seen directly (mineral oil helps); yeast and bacteria are identified by shape and staining. It's quick, inexpensive and the most accurate way to pick the right medication.
Does the Pure Majesty ear cleaner ship to Australia?
Yes. Shipping is free worldwide and Australian orders ship with duties and GST prepaid (DDP), so there is nothing to pay on delivery. The 120 mL Dog Ear Cleaner is A$43.
The bottom line
Get the swab, treat every pet if it's mites, finish the course if it's an infection — then keep those ears clean and comfortable. Order the Pure Majesty Pets Dog Ear Cleaner for A$43, with free shipping to Australia and duties and GST prepaid.
