It's really distressing to see your dog constantly shaking their head, scratching at their ears or looking uncomfortable. You want to help them, right? And you want to know what's causing the irritation.
Often, excessive head shaking points to ear mites in dogs. These are tiny parasites that can cause significant discomfort.
This guide will help you understand what ear mites are, recognise their symptoms, explain how vets diagnose them and guide you through effective, vet-approved treatment and prevention strategies to restore your pet's comfort.
Why is my dog shaking their head and scratching their ears so much?
When your dog persistently shakes their head and scratches their ears, it's a clear sign of discomfort originating from their ears. This behaviour is often a primary indicator that something's up, and ear mites are a highly contagious and common cause.
Your dog might also be suffering from other issues. These include:
- Bacterial or yeast infections
- Allergies
- Foreign bodies lodged in their ear canal
So, while ear mites are frequent offenders, these symptoms warrant a professional look.
What exactly are ear mites and how do dogs catch them?
Ear mites, scientifically known as Otodectes cynotis, are tiny, highly contagious parasites. They live predominantly in the ear canals of animals like dogs, cats and ferrets. You wouldn't typically see them with the naked eye, but their presence causes intense irritation and discomfort for your pet.
These mites have a life cycle of approximately three weeks, which they complete entirely on their host. They feed on ear wax and skin debris. Their constant movement and feeding cause significant irritation, leading to inflammation and that tell-tale itchiness.
Dogs usually catch ear mites through direct contact with an infested animal, whether that's another dog, a cat or even a ferret. This makes multi-pet households particularly vulnerable, as mites can quickly spread from one animal to another.
Recognising the signs: key symptoms of ear mites in dogs
Knowing what to look for can help you act quickly if you suspect your dog has ear mites. The symptoms can vary in intensity and may affect just one ear or both, but they generally point to significant ear irritation.
Persistent ear scratching and head shaking
This is often the first and most obvious sign you'll notice. Your dog might be constantly pawing at their ears, rubbing them on furniture or shaking their head vigorously – sometimes so much that you worry about them hurting themselves.
Dark, waxy, or 'coffee ground' discharge
When you look into your dog's ears, you might see a distinctive dark, crumbly discharge that often resembles coffee grounds. This isn't just dirt. It's a mixture of ear wax, mite debris and dried blood. A classic indicator of ear mites.
Unpleasant odour
An infested ear can develop a foul smell. This is due to the mites themselves, but also often from secondary bacterial or yeast infections that can take hold in the inflamed, moist environment the mites create.
Redness or inflammation of the ear canal
If you gently lift your dog's ear flap, you might see that the skin inside the ear canal looks red, swollen, or generally inflamed. Constant scratching and irritation can also lead to open sores or scabs around the ear opening.
Hair loss and skin lesions around the ears
Over time, relentless scratching can cause hair loss around the ears. Your dog might also develop scabs, scratches or thickened skin in the area. This can be quite uncomfortable for them and might even lead to further skin infections.
Recognising these signs early is crucial. While these symptoms can also point to other ear conditions, such as bacterial or yeast infections, it's always best to get a professional diagnosis to ensure your dog receives the correct treatment.
Should I try home remedies for my dog's ear mites?
If you suspect your dog has ear mites, it's really important to avoid self-diagnosing or trying home remedies you aren’t sure about. While it's natural to want to help your pet immediately, over-the-counter treatments and unproven remedies are often ineffective at eradicating mites. They can even worsen the problem or delay proper veterinary care.
Ear mite symptoms can mimic those of bacterial or yeast infections, which require entirely different medications. Without a proper diagnosis, you could be treating the wrong issue, allowing the actual problem to escalate.
If your dog is showing signs of ear discomfort, like scratching, head shaking or a dark discharge from the ears, it's best to arrange a veterinary examination. Your vet can confirm whether ear mites are present and recommend the most appropriate treatment.
Effective prescription treatments for ear mites are classified as POM-V (Prescription Only Medicine - Veterinarian) medicines in the UK. These medications can only be prescribed by a veterinary surgeon following a clinical assessment of your pet. This helps your dog receive the right treatment for their specific condition and supports safe, effective parasite control.
How a vet diagnoses ear mites
Your vet will carry out a thorough examination to accurately diagnose the problem. This typically involves:
- Visual examination: They'll look for general signs of irritation and discharge.
- Otoscopy: Using a special instrument called an otoscope, they can look deep into the ear canal, often spotting the tiny mites moving around.
- Microscopic analysis: Your vet might take a swab of the ear wax and examine it under a microscope. This is the most definitive way to identify the mites and differentiate them from other causes of ear problems.
While we offer lots of expert advice for dogs, getting a professional diagnosis is essential. It ensures your dog receives appropriate treatment, preventing unnecessary suffering and potential complications from an incorrect or delayed diagnosis.
Effective treatment through vet-approved solutions for ear mites in UK dogs
Once your vet has confirmed that ear mites are the cause of your dog's discomfort, they'll prescribe a specific treatment plan. It's vital to follow their instructions precisely to ensure the mites are fully eradicated and to prevent reinfestation.
Vet-prescribed medication
Treatments usually involve ear drops or spot-on medications specifically designed to kill mites at various life stages. These products contain antiparasitic ingredients that target the mites effectively.
Your vet will select the most suitable option based on your dog's individual needs and the severity of the infestation.
Why the full course of treatment is necessary
Even if your dog's symptoms improve quickly, completing the entire course of treatment is crucial. This is because ear mite eggs are resistant to most medications.
The treatment course must be completed as prescribed by your vet to ensure that all newly hatched mites are killed before they can mature and lay more eggs. Stopping treatment too soon is a common reason for recurrence.
The role of ear cleaning
In conjunction with medication, your vet will likely recommend regular ear cleaning. Products like our EpiOtic ear cleaner can help manage ear mites by clearing out the waxy build-up, debris and discharge where mites live.
This makes the ear canal a less hospitable environment for the mites and helps the prescribed medication work more effectively. It's a supportive measure that aids overall ear health during treatment.

How to prevent recurrence of ear mites
Preventing ear mite recurrence involves a multi-pronged approach, focusing on treating all affected animals, decontaminating the environment, and maintaining good ear hygiene. It's all about breaking the mite's life cycle and preventing them from returning.
Addressing multi-pet households
If you have other pets, whether it’s another dog, a cat or a ferret, it's crucial that all of them are treated simultaneously, even if they're not showing symptoms. Ear mites are incredibly contagious and can easily jump from one animal to another.
If you only treat one pet, the others can quickly become a source of reinfestation for the treated animal. This is a common pitfall when trying to eradicate mites.
Household decontamination
While ear mites primarily live on pets, they can survive for a short time in the environment. It's a good idea to thoroughly clean and decontaminate your home, especially areas where your pets spend a lot of time. This includes:
- Washing all bedding, blankets, and pet toys in hot water.
- Vacuuming carpets, rugs and upholstery regularly, and disposing of the vacuum bag immediately.
- Cleaning grooming tools with an appropriate disinfectant.
While household sprays like Indorex Defence Household Flea Spray are effective against house dust mites and fleas, they aren't specifically designed to kill ear mites and must never be applied directly to animals. Their main benefit in this context is general household hygiene.
Regular ear cleaning and parasite control
Maintaining regular ear hygiene is key. Using an appropriate ear cleaner for dogs, such as EpiOtic Ear Cleaner, can help remove wax and debris. This product cleans and deodorises, supporting a healthy ear environment.
Regular parasite control, often part of a broader flea and tick treatment regime, can also help prevent various external parasites, including ear mites. Discussing a comprehensive parasite control plan with your vet is always a good idea.
When to see your vet about your dog's ear mites
You should always consult your vet promptly if you notice any signs of ear discomfort in your dog. Early intervention is paramount for a quick recovery and to prevent more serious health issues.
Ignoring ear mite symptoms or attempting to treat them solely with unproven remedies can lead to several complications.
- Untreated ear mites can cause secondary bacterial or yeast infections, which are often more painful and difficult to resolve.
- Constant scratching can lead to skin damage around the ears, and in severe cases, even aural haematomas. These are blood blisters that form on the ear flap due to vigorous head shaking.
- In rare instances, chronic, untreated ear infestations can contribute to hearing loss.
Your vet can accurately diagnose the problem and provide the right treatment, putting your dog on the fastest path back to comfort and good health.
Worried about your dog's ear health?
If you're concerned about your dog's ear health or suspect they might have ear mites, don't hesitate to speak to your vet. They can accurately diagnose the issue and recommend the most suitable treatment plan.

Dog ear mite FAQs
What are the main symptoms of ear mites in dogs?
Primary symptoms of ear mites in dogs include excessive ear scratching, persistent head shaking, a dark, coffee ground-like discharge from the ears and an unpleasant odour. You might also notice redness, inflammation or hair loss around the ears. These signs can also indicate other ear conditions, so a veterinary diagnosis is essential.
How do dogs catch ear mites?
Dogs primarily catch ear mites through direct contact with an infested animal, such as another dog, a cat or a ferret. These tiny parasites are highly contagious and can easily spread in multi-pet households or through brief interactions with affected animals. While less common, they can also pick them up from the environment.
Can ear mites spread to other pets or humans?
Yes, ear mites easily spread between dogs, cats and ferrets within a household, making it crucial to treat all pets simultaneously if one is infected. Human infestation is very rare. While mites might temporarily transfer to humans, they typically don't establish permanent colonies on people.
How are ear mites diagnosed by a vet?
A vet diagnoses ear mites through a physical examination, often using an otoscope to look into the ear canal. The most definitive method involves taking a sample of ear discharge and examining it under a microscope to confirm the presence of mites. This professional diagnosis is crucial to differentiate ear mites from other ear conditions.
What is the best treatment for ear mites in dogs?
The most effective treatment for ear mites in dogs involves vet-prescribed medications, typically ear drops or spot-on treatments designed to kill the mites. A full course of treatment, as prescribed by your vet, is vital to break the mite life cycle.
How long does it take to get rid of ear mites in dogs?
Getting rid of ear mites in dogs typically takes several weeks, often three to four weeks, to complete the full course of treatment. This extended period is necessary because mite eggs are resistant to medication, so treatment must continue until all newly hatched mites have been killed to prevent reinfestation.
Can I use home remedies to treat ear mites in my dog?
It's strongly advised against relying solely on home remedies for ear mites. They’re generally ineffective at eradicating the mites and can delay proper veterinary treatment, potentially leading to complications like secondary infections. Only licensed and registered treatments are proven safe and effective, such as those prescribed by your vet.
How can I prevent ear mites in my dog?
You can prevent ear mites by ensuring all pets in a multi-pet household are treated if one is infected, maintaining good ear hygiene with appropriate ear cleaners, and incorporating regular parasite control as part of your dog's routine care. Regular vet check-ups also help in early detection and prevention.
