Ear mites are a frequent cause of ear problems if your dog has been shaking its head, pawing at its ears or a dark, crumbly discharge inside the ear canal. They are unpleasant, they are easily transmitted from pet to pet, and they will not go away without treatment — however the good news is that they are very treatable once understood.
Short Answer: The treatment for ear mites in dogs is usually a veterinarian prescribed or recommended parasite control medication (usually a spot-on or oral medication containing selamectin, moxidectin, or an isoxazoline), a gentle cleaning of the ears to remove debris, and treating all other pets in the home at the same time. Having a full life-cycle clearance can take up to a month, but most dogs improve within a few weeks.
What Are Dog Ear Mites?
Ear mites (Otodectes cynotis) are microscopic, eight-legged parasites that reside in a dog’s ear canal, where they feed on debris, wax and skin oils. They’re difficult to see with the naked eye, and may look like faintly visible white dots floating in your dog’s dark wax.
The entire life cycle (egg to adult) occurs in approximately three weeks and almost completely within the ear. This is one of the reasons why infestations can quickly escalate and why one application may not be sufficient to stop the cycle.
Ear Mite Treatment for Dogs: What Actually Works
Prescription and Vet-Recommended Treatments
Modern ear mite treatment for cats & dogs has moved well beyond old-fashioned ear drops. Veterinarians now most often reach for systemic parasiticides — products that treat the whole dog, not just the ear — because they clear mites more reliably and have residual protection against reinfestation. Common categories include:
- Isoxazoline-class products (e.g., afoxolaner, sarolaner, fluralaner) — oral chews or topical treatments originally developed for fleas and ticks that are also effective against ear mites
- Macrocyclic lactones (e.g., selamectin, moxidectin, ivermectin-based products) — topical spot-on treatments applied to the skin, commonly used for mite and heartworm prevention
- Topical ear-specific miticides — medicated ear drops applied directly into the canal, sometimes used alongside a systemic product
Since the life cycle of the mite takes approximately 3 weeks, many of these are repeated at intervals of a month or so to ensure that any eggs which hatch after the initial application are also dealt with.
The product and the dosage will be determined by your veterinarian and depend on your dog’s age, weight, medical history and if other pets in the household require treatment. Don’t use a cat-only or human-only product on a dog without your vet’s advice, as some cat products may be harmful to dogs.
How to clean the ears prior to treatment.
Your veterinarian might suggest cleaning out the debris with a vet-approved cleanser before or in addition to using medication. This allows for the direct contact of the treatment with the mites and will help to monitor healing. Use a cleanser that is designed for a dog’s ear, and use it as directed by your veterinarian — the insertion of cotton swabs too deeply into the canal can cause injury.
Treating all pets in the household
Ear mites are easily spread between animals that are in close contact, so all cats and dogs in the household, even those that are not yet showing symptoms, should be treated simultaneously. One of the most common reasons mites return is if you skip this step.

Ear Mite Symptoms in Dogs
The symptoms of ear mites in dogs are related not to the depth of the mites’ bites, but to irritation and allergic type response to the mites’ excretions. Watch for:
- Scratching and pawing ears often.
- Shake or tilt head.
- A crumbly discharge that is dark brown, black, or reddish-brown (like coffee grounds).
- A foul or strong smelling odor from the ear.
- Inside the ear or around the edge of the ear flap that is red or scabbing.
- Scratching causes hair loss around the ears.
- In more serious or chronic cases, a lump of blood (a haematoma) may develop on the ear flap created by repeated shaking of the head.
Ear Mite Discharge: what you may see.
The classic symptom that many sign owners notice first is a dry, dark, granular substance which looks like coffee grounds or dried blood. It is typically more crumbly than the greasy, yellow discharge that is found with a bacterial or yeast ear infection.
Ear Mites vs. Ear Infections: How to Tell the Difference
Ear mites can be mistaken for a simple ear infection, caused by bacteria or yeast, because both conditions result in scratching, shaking of the head and discharge from the ears, although the treatment is different, so it is important to make the correct diagnosis.
| Feature | Ear Mites | Bacterial/Yeast Infection |
|---|---|---|
| Cause | Parasite (Otodectes cynotis) | Bacteria or yeast overgrowth |
| Discharge | Dark, dry, crumbly (“coffee grounds”) | Yellow, brown, or greasy; often smelly |
| Contagious to other pets | Yes, highly | No |
| Common in | Puppies, dogs from shelters/multi-pet homes | Dogs with allergies, floppy ears, or moisture exposure |
| Diagnosis | Otoscope exam or microscope swab | Ear cytology (swab under microscope) |
| Treatment | Parasiticide + ear cleaning | Antibiotic/antifungal ear drops |
It’s possible for the two to exist together as well: irritation from the mites allows bacteria or yeast to take hold, so the only correct way to determine what you are treating is to visit your vet with a proper ear swab.
How Dogs Get Ear Mites
Ear mites are spread by direct contact with an infested animal making them particularly common in:
- Puppies at a shelter, from breeders or from pet stores
- Home ownership of more than one cat or dog.
- Dogs that hang around outdoor or stray cats
- Adopted pets that have not had a veterinary examination.
Mites can also survive for a short period of time off the host, such as in bedding, carpet or grooming tools, so environmental cleaning is important during treatment.
How Vets Diagnose Ear Mites
A veterinarian will use an instrument called an otoscope to examine the ear canal for the mites and will also collect a sample of the ear discharge to view under a microscope. This is significant as it eliminates — or proves — that there is no secondary bacterial or yeast infection, which would require further treatment.
This should not be overlooked even if you are sure it is mites. Treat the wrong condition and waste the time and allow the real condition to worsen.
Top Ear Mite Treatment for the Dog – What Works?
Prescription & Vet Recommended Treatments
Ear mite treatment is far removed from old fashioned ear drops. Today, systemic parasiticides (a product that treats the entire dog, rather than just the ear) are more commonly used by vets as they are more effective at removing mites and provide a margin of safety against reinfestation. Common categories include:
- Isoxazoline class products: (such as afoxolaner, sarolaner, fluralaner) – Oral chews or topical products that were originally made for flea and tick control, but are also effective against ear mites.
- Macrocyclic lactones: Many topical spot-on products (e.g., selamectin, moxidectin) containing macrocyclic lactones are used to control mites and heartworms.
- Topical ear-specific miticides: (medicated ear drops with the medication applied directly into the ear canal, possibly combined with a systemic product)
The mite life cycle is approximately three weeks and as a consequence, many of these treatments are repeated, usually one month apart, to cover the hatching of eggs (that have escaped treatment) following the first application.
Your veterinarian will select the appropriate product and schedule of treatment depending on your pet’s health history, age, weight, and if other pets in the household require treatment. Do not use a cat-specific product or off-label human product on a dog unless directed by a veterinarian — some may be harmful to dogs.

Cleansweep Ears before treatment:
Your veterinarian might suggest gently flushing out the debris that has accumulated with a vet-approved ear cleanser, before or in addition to administering any medication. This allows the treatment to be more effective with the mites, and the healing process can be more closely monitored.
Use only a special cleanser for dog ears as directed by your veterinarian; using cotton swabs and pushing them too deeply into the ear canal can injure the ear.
Treating all pets in the home
The ear mites are readily transferred from one animal to another, so it is important to treat all cats and dogs in the home at the same time, including asymptomatic animals. One of the most common causes for mites to return is if this step is not followed.
Can You Treat Dog Ear Mites at Home?
Cleaning and comfort care can be done at home, but the ear mites require a true parasiticide to kill them — cleaning them can’t do the trick. Some owners resort to home remedies such as mineral oil and diluted vinegar, while some of these may help to remove debris, they do not necessarily kill mites or their eggs and using the wrong kind of remedy in an already-irritated ear can cause further problems.
When ear mites are suspected, the quickest and safest route is to get to a vet who can diagnose the mites and prescribe a dose.
How Long is Ear Mite Treatment?
Treatment usually begins to take effect in 1-2 weeks, but because the mites have a life cycle of about 3 weeks, a follow-up dose may be required 30 days after the initial application. If you’re using a treatment that isn’t supposed to last as long, you may need to have your vet check the ears again to determine that they are clear before stopping.
Ear mites are commonly seen in dogs, cats, and ferrets.Ear mites are a common ailment of dogs, cats and ferrets.
Common Mistakes When Treating Ear Mites
- Early termination of treatment after signs of success, allowing eggs to hatch and re-infest the area.
- Only treating a pet that is showing signs of infestation, and leaving other household pets as a source of reinfestation.
- Relying on home remedies that are not proven effective rather than a parasiticide.
- Over-cleaning or probing into the ear canal (may hurt or cause injury to the ear).
- When it may be an infection that needs different medication, but is assumed to be mites without a vet check.
- Failure to clean bedding and grooming equipment, providing opportunity for mites to live in the environment.
Preventing Ear Mites in Dogs
- Maintain year-round flea, tick and mite control products recommended by your veterinarian (some of which also control ear mites)
- Have new pets checked by a vet before introducing them to your household
- Regularly examine your dog’s ears for wax, odor or discharge
- Wash pet bedding often, particularly following a treatment for parasites.
- Avoid close, unsupervised interactions with animals you do not know or that aren’t following you.
Can Ear Mites Be Transmitted to People or Other Pets?
Ear mites are easily transmitted from dog to cat and vice versa. Humans can be infected, but this is rare — and, in people with close contact with heavily infested animals, the infection is mild and temporary, causing skin irritation. While treatment is going on, good hygiene (handwashing after handling an infested pet) is a sensible precaution.
When to Take Your Dog to the Vet?
If you observe any of the following, call your veterinarian right away:
- Sudden, painful swelling of the ear flaps (may be a hematoma)
- Ear swelling and/or heat along with an unpleasant smell
- Your dog cannot maintain the head level or has a loss of balance
- Bleeding or lesions of the ear and surrounding areas
- No response to therapy started as directed
FAQs
What are ear mites in a dog’s ear?
Ear mites themselves are barely visible, but look like white specks crawling along dark wax; most owners first notice the discharge which is a crumbly mass of dry, dark brown or dark to black debris that looks like coffee grounds.
Where dogs pick up ear mites?
Ear mites are transmitted via direct contact with an ear mites affected cat or dog. They are particularly prevalent in puppies, shelter animals and homes with several pets.
Are ear mites an ear infection?
Bacterial or yeast infection is the cause of most ear infections, and ear mites are caused by a parasite. They may sound alike and often appear together, so it’s best to have your pet checked by a veterinarian.
Is it possible to treat ear mites in dogs without seeing a veterinarian?
Ear cleaning products can be used as a comfort for the ear, but are not effective at killing the mites reliably. The quickest and safest results come from a proper diagnosis and a good parasiticide drug from your veterinarian.
How long will it take to get rid of ear mites in dogs?
Dogs usually improve within 1-2 weeks, and complete treatment is usually approximately one month, including a second dose or recheck visit to allow for the life cycle of the mite.
Should I treat my other pets also?
Yes. Ear mites are very contagious among household pets and if only the affected dog is treated with ear drops and the cat or other dog is not treated, it is likely that the ear mites will infect the dog again.
Are ear mites harmful?
If left untreated, constant scratching and head shaking can result in one or more of the following: hematoma on the ear flap or secondary infection. Most dogs will make a complete recovery with timely treatment.
Are puppies at risk of ear mites?
Yes — puppies, particularly those from pet stores or shelters, tend to be a problem as they have not yet begun their regular parasite control.
Does a dark waxy ear necessarily indicate mites?
Not necessarily. Another cause of dark discharge is an excess build up of wax or yeast infection so a vet exam is the best way to determine the cause.
Will simply cleaning my dog’s ears help cure my dog’s mites?
No, cleaning helps remove debris and can help make the dog more comfortable, but only an actual parasiticide will kill the mites or the eggs.
