Ear Mites In Dogs: Everything to Know & Best Treatments

This content was reviewed and fact-checked by veterinarian Dr. Aukse Caraite, DVM.

This is your complete guide to ear mites in dogs. If your pup shakes his head or scratches his ears more than usual, tiny parasites known as ear mites might be the cause. These mites can lead to intense itchiness and other ear-related problems. It’s important to understand the basics of this common parasite so you can keep your dog comfortable, healthy, and safe. So, what should you do if you suspect an ear mite infestation? This guide covers everything you need to know—from symptoms and causes to treatment and prevention. Let’s get started!

What Are Dog Ear Mites?

Ear mites are tiny eight-legged, highly contagious parasites that live in the ear canals of dogs and other animals. The most common species affecting dogs is Otodectes cynotis, a surface mite that feeds on ear wax, oils, and skin debris. Although barely visible to the naked eye, these mites can cause intense irritation and inflammation in your dog’s ears. These parasites are part of the arachnid family—yes, they’re related to ticks and spiders—and they thrive in warm, moist environments like the ear canal. Once inside, they quickly multiply, triggering allergic reactions and secondary infections if left unchecked. Unlike other parasites, ear mites do not burrow under the skin and are relatively easy to treat.

Lifecycle

The lifecycle of Otodectes cynotis spans about 3 weeks:

1. Eggs are laid by the adult mites deep inside the ear canal.
2. Larvae hatch within 4 days and begin to feed.
3. The larvae molt into nymphs, which then develop into adult mites.
4. Adult mites live for about 2 months and continue the cycle by laying more eggs.

A single infestation can quickly grow out of control if not addressed, especially since these mites don’t just stay confined to one pet — they spread fast. After ear mite eggs hatch, these new ear mites can lay eggs too.

Are Dog Ear Mites Contagious?

Yes, ear mites are highly contagious, and you should isolate your infected pet from other pets. Ear mites can move from one dog to another in close contact and eventually reach the ear.

Causes of Ear Mites in Dogs

Ear mites are highly contagious and commonly spread through close contact with infected animals, especially cats. Dogs can easily become infested at dog parks, shelters, or in multi-pet households. In addition to direct contact, ear mites can survive briefly off a host, allowing dogs to pick them up from shared bedding, grooming tools, crates, or other contaminated items. Due to age, illness, or stress, dogs with weakened immune systems are also more susceptible to infestations. Lastly, poor ear hygiene creates the perfect environment for mites to thrive, as wax buildup and debris provide a rich food source and breeding ground.

Symptoms of Ear Mites In Dogs

Recognizing the symptoms early is crucial for prompt treatment and preventing complications. Common signs of ear mite infestation include:​

Secondary infections: Continuous scratching can lead to open wounds, making the ears susceptible to bacterial or yeast infections. As the infestation grows, ear mites may invade other parts of the dog’s body.

Health Risks of Ear Mites In Dogs

Diagnosing Ear Mites in Dogs

​Diagnosing ear mites in dogs involves a combination of clinical evaluation and diagnostic tests to ensure accurate identification and appropriate treatment.​

1. Veterinary examination: A veterinarian will begin with a thorough physical examination, focusing on the ears. They will inquire about your dog’s medical history, symptom onset, and recent interactions with other animals, as ear mites are highly contagious.

2. Otoscopic examination: Using an otoscope, the veterinarian will inspect the ear canal for signs of ear mites, such as inflammation, redness, and dark, crumbly discharge resembling coffee grounds. In some cases, the mites may be visible as tiny white specks moving within the ear canal. ​

3. Microscopic evaluation (ear cytology): To confirm the presence of ear mites, the veterinarian may perform an ear cytology

• Sample collection: A cotton swab is gently used to collect debris from the ear canal.​
• Microscopic analysis: The sample is mixed with mineral oil on a slide and examined under a microscope to detect mites or their eggs.

4. Differential diagnosis: Since other conditions like bacterial or yeast infections can mimic ear mite symptoms, the veterinarian may conduct additional tests to rule out these possibilities and ensure the correct treatment plan.

What Do Ear Mites In Dogs Look Like?

Best Ear Mite Treatment In Dogs

Treating ear mites (Otodectes cynotis) in dogs requires a comprehensive approach to eliminate the infestation, relieve discomfort, and prevent recurrence. The process begins with ear cleaning, where a veterinarian uses appropriate solutions to remove debris and wax, enhancing the efficacy of medications. This is followed by topical medications, such as selamectin (e.g., Revolution®) or moxidectin/imidacloprid (e.g., Advantage Multi®), which are applied to the skin and effectively eradicate ear mites. Over-the-counter products, like PetArmor Ear Mite Treatment, may also be available but should only be used under veterinary guidance to ensure safety and effectiveness.

In some cases, oral and injectable medications are prescribed. Ivermectin, administered orally or via injection, is a potent antiparasitic often used off-label for ear mite treatment. However, certain breeds may be sensitive to ivermectin, making veterinary consultation essential. Sarolaner (Simparica®), an oral chewable medication, is another effective option that treats fleas, ticks, and ear mites. Additionally, environmental management plays a crucial role in preventing reinfestation. All household pets should be treated simultaneously since ear mites are highly contagious, and pet bedding, toys, and grooming tools must be thoroughly cleaned.

Follow-up care is critical to ensure the infestation is fully resolved. This involves monitoring through follow-up visits with the veterinarian and implementing preventative measures such as regular ear inspections and maintaining overall ear health.

Best Ear Mite Medicine For Dogs

There are a variety of different medical treatment options your veterinarian may recommend.

1. Best Vet-Prescribed Ear Mite Medications For Dogs

Here are the most commonly used medications for dogs with ear mites.

Based on available data and clinical studies, the most effective dog ear mite treatments are Revolution® (Selamectin) and NexGard® (Afoxolaner). Revolution stands out for its 100% efficacy after a single topical application, making it fast-acting and convenient. NexGard, an oral chewable, also achieved 100% efficacy by Day 42 after two monthly doses, offering a reliable alternative for dogs that prefer oral treatments. Other highly effective options include NexGard Spectra® (Afoxolaner + Milbemycin Oxime), which reached 99.9% efficacy within 28 days, and Bravecto® (Fluralaner), which showed 99.8% efficacy after one dose and provides long-lasting protection. Simparica® (Sarolaner) also performed well, with 93.3% efficacy at Day 60. Injectable Ivermectin and Advantage Multi® (Imidacloprid + Moxidectin) are reliable alternatives, though they typically require multiple doses and may not act as quickly. Overall, Revolution offers the best speed, ease, and effectiveness, while NexGard and NexGard Spectra provide excellent oral options for comprehensive parasite control.

2. Home Remedies For Ear Mites In dogs (OTC Treatments)

While various sources suggest some home remedies like green tea rinses or oil treatments, their efficacy is not scientifically proven. Consulting a veterinarian before attempting any home-based therapies is essential for safe and effective care

Here are some of the most effective over-the-counter treatments to kill ear mites at home.

Green Tea Rinse: Green tea acts as a natural antiseptic, helping to cleanse the ear canal and reduce inflammation.​ Brew a cup of green tea, let it cool to room temperature, and place a few drops into your dog’s ear with a dropper. This can help remove mite debris and promote healing. Repeat daily until the mites are gone. Ensure the tea is completely cooled before application to prevent burns. While gentle, green tea rinses may not be potent enough to eradicate a significant mite infestation.

Apple Cider Vinegar: Apple cider vinegar (ACV) contains acetic acid, a natural antibacterial and antifungal compound. Acetic acid is bactericidal that prevents the growth of bacteria into many microorganisms. ACV also helps rebalance the ear’s pH and may create an environment less hospitable to mites. Mix equal parts raw, unfiltered apple cider vinegar and distilled water. Soak a cotton ball in the solution and gently wipe the visible parts of your dog’s inner ear. Repeat once daily. Never use ACV on raw, inflamed, or broken skin, as the acidity can cause stinging and further irritation. Always dilute, and avoid deep application into the ear canal.

Oil Treatment (General): Carrier oils such as olive, almond, or mineral oil can smother mites and loosen wax and debris, aiding in their removal. Warm the oil slightly and place a few drops into the ear canal using a dropper. Massage gently and clean the ear with a cotton pad after a few minutes. Repeat daily. Use only food-grade oils and avoid essential oil blends unless a vet approves. Oils may need to be applied consistently for weeks, and buildup should be avoided. Premo Guard Plant-Based Oils Pet Protector Spray on Amazon is a great choice.

William Miller Jr., VMD, a professor of dermatology at Cornell University’s College of Veterinary Medicine, says that “there are many topical, oral, and systemic agents and most such as ivermectin are highly effective… even one old-time remedy – baby oil- can [get rid of ear mite infestation].”^[1] Simply put a few drops into an affected ear several times a day for a month. This usually smothers the mites,” Dr. Miller notes.

Aloe Vera Gel: Aloe vera contains compounds like aloin and acemannan, which help soothe inflammation, reduce itchiness, and support skin healing—making it ideal for irritated ears. Apply a thin layer of 100% pure aloe vera gel (without additives or alcohol) to the outer part of the ear using a clean cotton swab or pad. Do not apply deep into the ear canal. Only use pet-safe aloe products and free from added preservatives, as some ingredients in commercial gels can be toxic to dogs. Four Paws Aloe Ear Mite Treatment For Dogs on Amazon is an aloe vera-based anti-ear mite product that’s worth checking out.

Many dog owners swear by Vaseline for ear mites—but does it really work? Before you reach for the jar, there are a few things you need to know. Discover the truth and how to use it safely in our full guide.

Ear Mite Prevention for Dogs

Regularly wash and sanitize items your dog comes into contact with.

How To Prevent Dog Ear Mite Infection From Happening Again

A study concluded that environments previously inhabited by animals infested with ear mites should be disinfected or left unoccupied for at least 12 days to prevent rreinfestation^[2]. Other tips include:

How To Get Rid Of Ear Mites In Your House

Here’s a clean visual checklist of how to get rid of ear mites in your house:

🔁 1. Treat All Pets: Medicate every pet in the household—even if they show no symptoms.

🧺 2. Wash Bedding: Wash pet beds, blankets, and soft toys in hot water and dry on high heat.

🧼 3. Disinfect Hard Surfaces: Clean floors, crates, and baseboards with a pet-safe disinfectant.

🧹 4. Vacuum Daily: Vacuum carpets, rugs, and furniture; empty the vacuum after every use.

📆 6. Repeat for 2–4 Weeks: Continue cleaning until the full mite life cycle is eliminated.

Ear Mites In Puppies

Ear mites are a common and uncomfortable problem in puppies. Because puppies have developing immune systems and are often in close contact with their mother or littermates, they’re especially vulnerable to infestations. The signs of ear mites in puppies are usually hard to miss. Your puppy may constantly scratch their ears, shake their head, or rub their head against furniture or the floor. You might also notice dark, crumbly debris inside the ears—often described as looking like coffee grounds—along with redness, swelling, and an unpleasant odor.

If left untreated, ear mites can lead to secondary bacterial or yeast infections, ear damage, or even hearing loss. Fortunately, treatment is straightforward. To help prevent reinfection, clean your puppy’s bedding, toys, and environment thoroughly. Routine ear checks and regular grooming can also help catch problems early.

How Long Does It Take To Get Rid of Ear Mites In Dogs?

The time it takes to get rid of ear mites in dogs entirely depends on the severity of the infestation and the treatment used—but most cases clear up within 2 to 4 weeks. Fast-acting medications often begin killing mites within 24–48 hours. However, even after the mites are gone, treatment usually continues for a few weeks to eliminate all mite eggs and life stages. Veterinarians often recommend continuing treatment for at least three weeks, which aligns with the mites’ lifecycle. This helps prevent reinfestation from any remaining eggs that hatch after the first round of treatment. If your dog’s ears are inflamed or infected, your vet may also prescribe anti-inflammatory or antibiotic medications, which can extend the recovery timeline slightly.

Can Humans Get Ear Mites From A Dog?

Humans can technically get ear mites from dogs, but it is extremely rare. The most common type of ear mite found in dogs is Otodectes cynotis, which primarily affects animals like dogs, cats, and ferrets. These mites are not well adapted to living on humans and typically do not thrive outside their preferred hosts. In unusual cases, a person with close contact with an infested pet may experience temporary itching, skin irritation, or a rash—especially around the ears or neck. However, full infestations in human ears are exceptionally uncommon. To reduce any potential risk, it’s important to treat your dog promptly if ear mites are diagnosed, maintain good hygiene by washing hands after handling pets, and regularly clean pet bedding and shared spaces. If you experience unusual symptoms after being in contact with an infected pet, it’s best to consult a healthcare provider for evaluation and peace of mind.
