Ear mites are a common problem for dogs, especially those who spend time outdoors or in environments with other animals. While these tiny parasites may seem like a minor issue, they can actually lead to serious health problems if not treated promptly.
Ear mites in dogs are particularly problematic because they not only cause discomfort but can also lead to infections, hearing loss, and long-term damage if left untreated.
Understanding what ear mites are, how they affect dogs, and how to treat and prevent them is vital for any responsible pet owner.
In this guide, we’ll explore everything you need to know about ear mites in dogs, from symptoms and causes to treatments and prevention.
What Are Ear Mites?
Ear mites (scientifically known as Otodectes cynotis) are microscopic parasites that live in a dog’s ears, feeding on the wax and oils found inside the ear canal. These parasites are highly contagious and can spread rapidly between dogs, especially in environments like shelters, kennels, and multi-pet households. Ear mites are more common in puppies and outdoor dogs, but any dog can be affected.
The mites live in the ear canal and typically cause inflammation and irritation. Although they are not life-threatening, the discomfort they cause can lead to excessive scratching, head shaking, and potential secondary infections if left untreated.
Symptoms of Ear Mites in Dogs
Ear mites are often difficult to detect early on because of their small size. However, there are several common symptoms that dog owners should watch for:
1. Excessive Scratching: One of the first signs of ear mites is your dog constantly scratching their ears, often leading to raw or irritated skin around the ears.
2. Head Shaking: Dogs with ear mite infestations will often shake their heads in an attempt to relieve the itching or discomfort caused by the parasites.
3. Dark, Crusty Ear Discharge: You may notice a dark, waxy, or coffee-ground-like substance in your dog’s ears. This discharge is typically a sign of ear mites, as they feed on ear wax and oils, leaving behind waste material.
4. Redness and Swelling: The inside of the ear may appear inflamed, red, or swollen due to the irritation caused by the mites.
5. Odor: A strong, foul smell coming from your dog’s ears could be a sign of an infection that may result from an ear mite infestation. The itching and irritation often cause the dog to scratch excessively, which can lead to bacterial infections.
6. Ear Sensitivity: Dogs with ear mites may show signs of discomfort when their ears are touched. If your dog pulls away or becomes agitated when you attempt to examine their ears, it could be due to ear mite infestation.
7. Loss of Balance: In more severe cases, ear mite infestations can lead to an infection of the inner ear, which can result in symptoms such as dizziness or loss of balance.
8. Hair Loss Around the Ears: Constant scratching can cause hair loss around the ears, making it easier to identify the problem.
How Do Dogs Get Ear Mites?
Ear mites are highly contagious, and the primary way dogs get them is through contact with other infected animals. Some of the common sources of ear mites include:
Other Dogs: Ear mites can easily spread from one dog to another, especially in environments like dog parks, kennels, and shelters.
Outdoor Exposure: Dogs that spend a lot of time outside, particularly in areas with wild animals, are more susceptible to ear mites. Wild animals like raccoons, foxes, and cats are common carriers.
Cats: Cats are frequent hosts of ear mites and can easily transmit the parasites to dogs, especially if they share the same living space.
Other Pets: Although dogs are the primary hosts of ear mites, other pets such as rabbits and ferrets can also carry the mites and transmit them to dogs.
Dangers of Ear Mites in Dogs
While ear mites themselves are not typically life-threatening, they can cause a range of complications that pose serious health risks to your dog. The dangers of ear mites in dogs include:
1. Secondary Infections: Constant scratching and irritation caused by ear mites can damage the skin and ear canal, creating an environment where bacteria and yeast can thrive. This can lead to otitis externa (outer ear infection), otitis media (middle ear infection), or otitis interna (inner ear infection).
2. Hearing Loss: Severe or chronic ear mite infestations can lead to permanent damage to the ear canal or eardrum, potentially causing partial or complete hearing loss. The inflammation and thickening of the ear canal can block sound waves from reaching the eardrum, affecting your dog’s ability to hear properly.
3. Balance Problems: If the mites infest deeper parts of the ear, especially the middle or inner ear, they can affect the dog’s balance, leading to symptoms like dizziness, stumbling, and loss of coordination.
4. Chronic Itching and Discomfort: The irritation caused by ear mites can be persistent and highly uncomfortable for your dog. If left untreated, the constant itching and scratching can result in deep, painful sores and infections, which can be difficult to heal.
5. Spread to Other Pets: Ear mites are highly contagious, so if one dog in your household becomes infected, it’s likely that other pets, including cats, may also get the mites. This can lead to an ongoing cycle of infestations if not managed properly.
Diagnosing Ear Mites in Dogs
If you suspect your dog may have ear mites, it’s important to visit a veterinarian for a proper diagnosis. The veterinarian will examine your dog’s ears and may use an otoscope (a tool with a light and magnifying lens) to get a closer look inside the ear canal.
They may also take a sample of the ear discharge and examine it under a microscope to identify the ear mites.
In some cases, the veterinarian may recommend additional tests to rule out other causes of ear infections or inflammation, such as bacterial or fungal infections.

Treatment of Ear Mites in Dogs
The treatment for ear mites typically involves the following steps:
1. Ear Cleaning: The first step in treating ear mites is thoroughly cleaning your dog’s ears to remove the excess wax and debris. This helps to ensure that the medication is effective and can reach the mites. Your veterinarian may perform the ear cleaning or provide you with a special ear cleaner to use at home.
2. Topical Medications: There are several medications available to treat ear mites in dogs. These medications are usually in the form of ear drops or topical treatments that are applied directly to the ear canal. Some common treatments include ivermectin, selamectin, milbemycin oxime, and moxidectin. These medications work by killing the mites and preventing further infestation.
3. Oral Medications: In some cases, oral medications like ivermectin or milbemycin oxime may be prescribed to treat ear mites. These medications work systemically to eliminate the mites from the inside out.
4. Antibiotics or Antifungal Medications: If a secondary infection is present (due to bacteria or yeast), the veterinarian may prescribe antibiotics or antifungal medications to address the infection and reduce inflammation.
5. Follow-Up Appointments: It’s essential to follow your veterinarian’s instructions and schedule any follow-up appointments to ensure that the mites have been completely eradicated. Additional treatments may be needed if the infestation is severe or persistent.
Preventing Ear Mites in Dogs
Preventing ear mite infestations is crucial, especially if you have multiple pets or live in an area with a high risk of exposure. Here are some tips to reduce the risk of ear mites in your dog:
1. Regular Ear Inspections: Check your dog’s ears regularly for signs of irritation, discharge, or abnormal odor. Early detection of ear mites can help prevent a full-blown infestation.
2. Maintain Good Ear Hygiene: Keeping your dog’s ears clean and dry is essential to prevent ear mites and other infections. Your veterinarian can recommend an ear cleaner suitable for your dog.
3. Limit Contact with Infected Animals: If you know that a dog, cat, or other pet has ear mites, limit contact until the problem is resolved. If your dog frequents dog parks or interacts with other animals, be vigilant about checking for signs of mites.
4. Flea and Parasite Control: Use a reliable flea and parasite control program to reduce the risk of ear mites, as they are often spread through contact with other infected animals.
