As a pet parent, one of your primary concerns is ensuring your dog remains healthy and comfortable. While dogs may suffer from various health issues throughout their lives, ear mites are among the most common and troublesome conditions that affect dogs.
These tiny parasites can cause significant discomfort and, if left untreated, lead to serious ear infections and even hearing loss.
In this comprehensive guide, we’ll explain how to spot ear mites in dogs, the symptoms to watch out for, the potential dangers, and the best ways to treat and prevent ear mite infestations.
Whether you’re dealing with a suspected ear mite problem or simply want to know how to safeguard your dog against them, this article has all the information you need.
What Are Ear Mites?
Ear mites (scientifically known as Otodectes cynotis) are microscopic parasites that thrive in the warm, wax-filled ear canals of dogs (and other animals). These mites feed on ear wax and oils, causing irritation and inflammation in the affected dog’s ear.
Ear mites are highly contagious and can spread rapidly between animals, particularly in homes with multiple pets, such as households with both dogs and cats.
While ear mites are not typically life-threatening, they can be incredibly uncomfortable for your dog. In addition, if left untreated, they can lead to painful secondary infections, ear canal damage, and hearing loss.
How Do Dogs Get Ear Mites?
Ear mites are spread through direct contact with infected animals. The mites move from one dog to another when they share living spaces, such as homes, kennels, or dog parks. Cats are another common carrier of ear mites, so if you have both cats and dogs, ear mites can easily spread between species.
Other common ways dogs get ear mites include:
Close contact with infected dogs or cats: Visiting shelters, boarding facilities, or dog parks increases the risk of exposure to infected animals.
Outdoor exposure: Dogs that frequently spend time outside, especially in environments where wild animals (such as raccoons, foxes, or rabbits) are present, are at a higher risk.
Stray animals: Dogs that come into contact with strays or feral animals can pick up ear mites easily.
Signs and Symptoms of Ear Mites in Dogs
Ear mites are small, making them difficult to detect at first. However, there are several telltale signs and symptoms that dog owners should be aware of. If your dog is displaying any of the following behaviors, it may indicate the presence of ear mites:
1. Excessive Scratching and Head Shaking
One of the earliest and most noticeable signs that a dog has ear mites is excessive scratching or pawing at the ears. This scratching is an attempt by your dog to relieve the intense itching caused by the mites. You may also notice your dog shaking its head frequently, as if trying to rid itself of an annoying sensation inside the ear.
2. Dark, Waxy Discharge
If you inspect your dog’s ears, you may find a dark, waxy discharge that resembles coffee grounds. This discharge is a mixture of ear wax, mite waste, and skin debris. The appearance of this discharge is a strong indicator that ear mites are present.
3. Redness and Swelling
The inside of the ear may appear red or inflamed, which is a result of irritation caused by the mites feeding on the ear wax and oils. This inflammation can cause discomfort and may worsen over time if not treated.
4. Foul Odor
Ear mites can lead to secondary infections, especially bacterial or yeast infections. If your dog’s ears smell foul or particularly unpleasant, this could indicate that the ear mites have caused an infection.
5. Ear Sensitivity
If your dog shows signs of pain or sensitivity when you touch their ears, this could be due to the discomfort caused by the mites. Dogs with ear mite infestations often pull their heads away or yelp when their ears are touched.
6. Hair Loss Around the Ears
Constant scratching and head shaking can lead to hair loss around the ears. If your dog has developed patches of hair loss near their ears, this could be due to frequent scratching from the mite infestation.
7. Balance Issues
In severe cases, ear mites can invade deeper parts of the ear canal, affecting the inner ear. This can cause balance problems, resulting in dizziness, uncoordinated movements, and loss of balance.
The Dangers of Ear Mites in Dogs
While ear mites are not usually life-threatening, they can lead to a number of serious complications if left untreated. The mites themselves cause significant discomfort and irritation, but over time, the constant scratching and inflammation can result in:
1. Ear Infections: The irritation caused by ear mites can lead to bacterial or fungal infections in the ear canal. These infections can cause pain, swelling, and discharge, further complicating the condition.
2. Hearing Loss: If ear mites infest the middle or inner ear, they can damage the ear canal and eardrum, potentially leading to partial or permanent hearing loss.
3. Damage to the Ear Canal: Chronic scratching and inflammation can result in thickening or narrowing of the ear canal, which may require surgical intervention to correct.
4. Spread of Infection: If the ear mites are not treated, they can spread beyond the ears, potentially leading to more severe infections in other parts of the body.
5. Discomfort and Reduced Quality of Life: The constant itching and discomfort caused by ear mites can cause a significant decrease in your dog’s quality of life. They may become irritable, anxious, or even develop behavioral issues as a result of the constant pain.

How to Diagnose Ear Mites in Dogs
If you suspect your dog has ear mites, it’s important to consult a veterinarian for a proper diagnosis. Your veterinarian will perform a thorough examination of your dog’s ears, checking for signs of infection, irritation, or mite presence.
To confirm the diagnosis, your veterinarian may:
Inspect the ear canal using an otoscope, a special instrument that allows them to view the inner structures of the ear.
Examine ear discharge under a microscope to check for the presence of ear mites.
Rule out other causes of ear irritation, such as bacterial infections, yeast infections, or allergies.
Treatment for Ear Mites in Dogs
Once diagnosed, your veterinarian will recommend an appropriate treatment plan for eliminating ear mites and relieving your dog’s discomfort. Treatment generally involves the following steps:
1. Ear Cleaning
Before applying any medication, the veterinarian will likely clean your dog’s ears to remove wax, debris, and any mite-related discharge. Cleaning the ears thoroughly ensures that the medication can work effectively. You may also need to clean your dog’s ears at home with a veterinarian-recommended ear cleaner.
2. Medications
The main treatment for ear mites is a topical medication applied directly to your dog’s ears. These medications typically include:
Ivermectin: An antiparasitic medication that is highly effective against ear mites.
Selamectin: Often used as part of a monthly flea and tick preventative, selamectin is also effective against ear mites.
Moxidectin: Another effective treatment for ear mites that may be prescribed as an ear drop.
These medications will kill the ear mites and prevent further infestation. Depending on the severity of the infestation, you may need to apply the medication for several days or weeks.
3. Antibiotics or Antifungals
If your dog has developed a secondary infection due to the ear mites, your veterinarian may prescribe antibiotics or antifungal treatments to address the infection. These medications may be applied topically or given orally, depending on the nature of the infection.
4. Follow-Up Care
Ear mites can be persistent, so it’s essential to follow through with the treatment plan. Your veterinarian may schedule follow-up appointments to check for reinfestation or to monitor your dog’s recovery.
Preventing Ear Mites in Dogs
While it’s impossible to guarantee that your dog won’t contract ear mites, there are several steps you can take to minimize the risk of an infestation:
1. Regular Ear Inspections: Check your dog’s ears frequently for signs of ear mites, such as discharge, redness, or irritation. Early detection can make treatment easier and more effective.
2. Maintain Good Ear Hygiene: Keep your dog’s ears clean and dry to prevent the buildup of wax and oils, which can attract ear mites. Regular ear cleaning with a vet-approved solution can help.
3. Limit Contact with Infected Animals: Keep your dog away from animals that have known ear mite infestations. If your dog frequents kennels, shelters, or parks, be extra cautious.

4. Use Preventive Medications: Some flea and tick preventatives also protect against ear mites. Ask your veterinarian if such products are appropriate for your dog.
5. Treat All Pets in the Household: If you have multiple pets, particularly cats, treat them all for ear mites if one of them becomes infected. This prevents the spread of ear mites between animals.
