If your dog is constantly scratching, shaking their head, or suddenly has strange-smelling ears, it's often more than "just" dirt: Dog mites are an extremely common cause – especially ear mites in dogs. In this guide, you'll learn how to identify dog mites, what types there are, what really helps (including dog mite home remedies – but placed in context), and when you absolutely must see a vet.

Mites in Dogs: What Are They?
Dog mites are tiny arachnids that can live on the skin, in the coat, or in the ear. Some mite species are harmless, while others lead to severe itching, inflammation, and secondary infections. Mites in a dog's ear are particularly common because the ear canal is warm and protected – a perfect environment for parasites.
Important: Not every redness or scratch is automatically "mites." Allergies, yeast, bacterial infections, or foreign bodies can cause similar symptoms. A clear diagnosis saves time, money, and nerves.
How Do Ear Mites Develop in Dogs? – Biological Background
Ear mites in dogs are almost always transmitted through direct contact. The most common species, Otodectes cynotis, lives exclusively on the host and feeds on skin flakes and tissue fluid in the external ear canal.
The mites complete their entire life cycle on the animal:
- Egg → Larva → Nymph → Adult Mite
- Life cycle: approx. 18–28 days
- Reproduction directly in the ear environment
Due to the mechanical irritation and the mites' saliva, this leads to:
- Inflammatory reactions of the skin
- Severe itching
- Increased sebum and secretion production
This environment promotes secondary infections with yeast (Malassezia) and bacteria, which is why mites in a dog's ear rarely remain a "pure mite problem."
Ear Mites in Dogs: Symptoms, Contagion and Typical Signs
Ear mites in dogs (often: Otodectes cynotis) frequently cause a very typical mix of symptoms. Many specifically search for dog ear mites or ear mites dog because the suffering quickly becomes severe: constant head shaking, scratching, restlessness – and sometimes even pain.
Typical Symptoms of Ear Mites in Dogs
- Severe head shaking and scratching at the ear
- Dark, crumbly discharge (often "coffee-ground-like")
- Unpleasant odor from the ear
- Redness, swelling, warmth
- Sometimes head tilt or sensitivity to touch
Ear mites are highly contagious – especially with close contact to other animals. And yes: Mites in cats are relevant here, because ear mites are very often transmitted between dogs and cats. So if you have a multi-pet household, always consider all animals.
Attention: If your dog shows severe pain, scratches the ear until it bleeds, the discharge becomes purulent, or neurological symptoms appear (stumbling, severe head tilt), please seek immediate veterinary attention.
Why do ear mites cause such severe itching in dogs?
The severe itching from dog ear mites is not just mechanically caused. Scientific evidence confirms an immunological overreaction:
- Mite saliva acts as an allergen
- Release of histamine and inflammatory mediators
- Increased blood flow and swelling
Studies show that dogs with:
- Atopy
- Food intolerances
- Impaired skin barrier
react significantly more strongly to mites. Therefore, it makes sense to consider nutrition and gut health in cases of recurrent dog ear mites.

This doesn't replace a diagnosis, but it explains why "simply cleaning" is often not enough: For mites, targeted antiparasitic treatment is necessary – otherwise the cycle will immediately restart.
What Types of Mites Affect Dogs?
Besides dog ear mites, there are other types of mites that can cause similar problems:
- Ear mites (Otodectes) – primarily in the ear canal
- Sarcoptic mange mites (Sarcoptes) – very severe itching, highly contagious
- Demodex mites (hair follicle mites) – more common with immunodeficiency, often localized
- Harvest mites – seasonal, often affects paws/underside
Why this is important: Treatment differs depending on the mite species. That's why correctly identifying dog mites is so crucial.
Identifying Dog Mites: Diagnosis at the Vet and at Home
At home, you can gather clues (discharge, odor, scratching behavior, whether other animals show symptoms). The definitive diagnosis is usually made via:
- Otoscopy (examination of the ear canal)
- Swab / Microscopy (mites, eggs, secondary germs)
- Possibly skin scraping (if other mite species are suspected)
Especially with mites in a dog's ear, a swab is invaluable because yeast/bacteria are often also involved – then the therapy needs to be adjusted.
Treatment: What Really Helps Against Mites in Dogs?
The most effective treatment for ear mites in dogs usually consists of a combination:
- Gentle ear cleaning (as directed) to remove discharge/deposits
- Antiparasitic therapy (e.g., spot-on, ear preparation, or systemic – depending on findings)
- Treatment of secondary infections (yeast/bacteria), if present
- Co-treatment of all contact animals in the household, if necessary (especially for dogs + cats)
Important: Please do not put "just any" drops into the ear. Some home remedies/oils can coatther irritate the ear canal or worsen an existing inflammation.
Dog Mite Home Remedies: What's Useful – and What's Dangerous?
Useful (supportive): Hygiene, regular washing of blankets/beds, vacuuming, consistent cleaning according to the vet's plan.
Risky: Vinegar, alcohol, tea tree oil, garlic, or aggressive oils in the ear – these can irritate, be toxic, or damage the eardrum.
If you want to use a dog ear mite home home-care approach, then only as a supplement in the environment (not in the ear) – and only if veterinary therapy is ongoing.
Environment and Other Animals: How to Prevent Re-Infections
To prevent mites in dogs from becoming a recurring issue, the environment is important – especially in repeated cases:
✔ Wash blankets/covers at 60°C
✔ Thoroughly clean beds and upholstery
✔ Vacuum (including sofa/car)
✔ Wash brushes/leashes
✔ Check contact animals (dog/cat)
How BugBell Can Help: Nutrition for Skin, Coat and Immunity
You don't "feed away" mites – but: A stable organism with a healthy skin barrier and good digestion often copes better with irritation phases and secondary skin problems. This is where BugBell comes in: with easily digestible insect protein (well-tolerated by many dogs) and functional ingredients for skin, coat, and gut.
BugBell Tip: If your dog constantly has skin issues in addition to itching from ear mites, it's worthwhile to check the basics: food tolerability, gut flora, fatty acid profile, and micronutrients.
Gut Health and Mites: Is There a Connection?
Current veterinary research shows: A dog's immune system is closely linked to its gut flora.
Dogs with:
- Unstable gut flora
- Chronic digestive problems
- Highly processed feed
more often show:
- Skin inflammations
- Recurrent parasite problems
- Prolonged healing times
An easily digestible protein source (e.g., insect protein) and prebiotic components can support the body's natural defenses – alongside medical treatment.
Frequently Asked Questions About Ear Mites in Dogs
How quickly do ear mites in dogs disappear?
With the right treatment, itching and discharge often improve within a few days. It's important to continue the treatment consistently for the recommended duration, otherwise ear mites in dogs will quickly return.
Are ear mites in dogs contagious?
Yes. Ear mites in dogs are highly contagious – especially between dogs and cats. If multiple animals live together, all should be checked.
Can I treat mites in my dog's ear myself?
You can assist with cleaning and maintaining hygiene. However, the actual antiparasitic therapy should be medically supervised – especially if the ear is inflamed or the eardrum's condition is unclear.
What is the best dog ear mite home home-care approach?
For the ear itself, there is no safe "cure-all" home home-care approach. Useful things include environmental hygiene (washing, vacuuming) plus veterinary treatment. Aggressive substances in the ear can cause harm.
How can I identify dog mites if I don't see any?
The mites are tiny. They are often recognized indirectly: "coffee-ground" discharge, severe itching, head shaking, multiple animals affected. A veterinary swab provides certainty.

How common are ear mites in dogs? – Figures and Studies
According to parasitological surveys, ear mites in dogs are among the most common ectoparasites:
- Up to 20–25% of all dogs with ear problems show mite infestation
- Up to 40% in puppies and young dogs
- Significantly more common in multi-pet households (dog + cat)
Particularly relevant: In over 60% of cases, mixed infections (mites + yeast/bacteria) are present – a reason why pure home remedies are often not sufficient.
