Dog Ear Mites vs. Ear Wax: Understanding the Differences

icon October 12, 2023

When it comes to the health and well-being of our furry companions, it's essential to be knowledgeable about common issues they may face. One such issue that can affect dogs is ear problems, and two common culprits are ear mites and ear wax. While they might seem similar at first glance, they are vastly different in terms of their causes, symptoms, and treatments. In this article, we'll explore the distinctions between dog ear mites and ear wax, helping dog owners better understand and address these concerns.

Dog Ear Mites vs. Ear Wax: Understanding The Differences

Differentiating between ear mites and ear wax can be challenging, especially for dog owners who are not familiar with these issues. Here are some key distinctions to help you identify the problem:

1. Appearance of Discharge:
   - Ear mites often produce a dark, coffee-ground-like discharge.
   - Ear wax is typically yellow to brown in color, and the amount can vary from minimal to excessive.

2. Odor:
   - Ear mites may cause a foul odor from the ear.
   - Ear wax does not usually have a strong odor unless an infection is present.

3. Behavioral Signs:
   - Dogs with ear mites are more likely to scratch their ears intensely and shake their heads.
   - Excessive head shaking is common in dogs with both ear mites and excessive ear wax, but intense scratching is more indicative of ear mites.

4. Appearance of the Ear Canal:
   - Ear mites can cause redness and inflammation inside the ear canal.
   - Excessive ear wax can obstruct the ear canal but may not necessarily lead to inflammation.

5. Onset and Spread:
   - Ear mites are often contagious and can spread between animals.
   - Ear wax buildup is not contagious and is more related to individual factors such as breed predisposition or allergies.

6. Response to Treatment:
   - Ear mite infestations typically require specific medication to eliminate the parasites.
   - Excessive ear wax is managed by cleaning the ears to remove the buildup.

If you are uncertain about the cause of your dog's ear issues, it's always best to consult a veterinarian. They can perform a thorough examination, diagnose the problem, and recommend appropriate treatment.

Understanding Ear Mites

Ear mites, scientifically known as "Otodectes cynotis", are tiny parasites that infest the ears of dogs and other animals. They are a common issue, particularly in puppies and young dogs. These minuscule creatures belong to the arachnid family, similar to ticks and spiders, and can be challenging to detect with the naked eye.

Causes of Ear Mites in Dogs

Ear mites are highly contagious and can spread easily between animals. Common causes of ear mite infestations include:

1. Contact with Infected Animals: Dogs can contract ear mites through direct contact with another infected animal, whether it's a fellow dog, cat, or other furry friends.

2. Environmental Transmission: Ear mites can also survive in the environment for a limited time, so if your dog frequents areas where infected animals have been, they might pick up these pesky parasites.

Symptoms of Ear Mites in Dogs

Identifying ear mite infestations early is crucial to prevent discomfort and complications for your dog. Common symptoms of ear mites in dogs include:

1. Intense Itching: Dogs with ear mites often scratch their ears vigorously, as the mites cause irritation and discomfort.

2. Head Shaking: Excessive head shaking is another sign of ear mites, as dogs try to dislodge the bothersome pests.

3. Ear Odor: A foul odor coming from your dog's ears might indicate an ear mite infestation.

4. Dark Discharge: You may notice a dark, waxy discharge in your dog's ears. This discharge can resemble coffee grounds.

5. Inflammation and Redness: Ear mites can lead to inflammation and redness inside the ear canal.

Diagnosing and Treating Ear Mites

If you suspect your dog has ear mites, it's essential to consult a veterinarian for a proper diagnosis. Your vet will typically examine your dog's ears using an otoscope, a device designed for this purpose. They may also take a sample of the ear discharge to confirm the presence of mites.

Treatment for ear mites typically involves cleaning the ears to remove excess wax and debris, followed by administering medication to eliminate the mites. Topical ear drops or ointments are commonly prescribed, and your vet will provide guidance on how to apply them properly. It's crucial to follow your vet's instructions carefully to ensure successful treatment.

The Role of Ear Wax in Dogs

Ear wax, or cerumen, is a natural substance produced by the glands in your dog's ear canal. It serves several essential functions, such as trapping debris, preventing infection, and maintaining a healthy ear environment. Ear wax is a normal and necessary part of your dog's ear health.

Causes of Ear Wax Buildup in Dogs

While ear wax is natural, some dogs may produce more wax than others, leading to a buildup. Factors that can contribute to excessive ear wax in dogs include:

1. Breed Predisposition: Certain breeds, such as Cocker Spaniels and Retrievers, are more prone to ear wax buildup due to the shape of their ear canals.

2. Allergies: Dogs with allergies may experience increased ear wax production as part of their body's response to allergens.

3. Ear Infections: Infections can lead to an increase in ear wax production as the body's defense mechanism.

Symptoms of Excessive Ear Wax in Dogs

While ear wax itself is not a problem, excessive buildup can lead to issues. Symptoms of excessive ear wax in dogs may include:

1. Head Tilting: Your dog may tilt their head to one side as a response to discomfort caused by wax buildup.

2. Ear Scratching: Dogs might scratch their ears more frequently if they feel discomfort due to wax accumulation.

3. Shaking Head: Similar to ear mites, excessive head shaking can be a sign of discomfort from too much ear wax.

4. Reduced Hearing: In severe cases, a buildup of ear wax can partially obstruct the ear canal, leading to reduced hearing.

Managing Ear Wax Buildup in Dogs

If you suspect that your dog has excessive ear wax, it's essential to consult your veterinarian. Your vet can examine your dog's ears to determine the extent of the wax buildup and recommend an appropriate course of action.

Treatment for excessive ear wax typically involves cleaning the ears to remove the excess wax safely. Your vet may use specialized ear-cleaning solutions and instruments to perform this procedure. In some cases, your vet may recommend regular ear cleaning as a preventive measure if your dog is prone to wax buildup.

Preventing Ear Problems in Dogs

Preventing ear problems in dogs is often more manageable than treating them. Here are some steps you can take to help keep your dog's ears healthy:

1. Regular Cleaning: Depending on your dog's breed and individual needs, your vet may recommend regular ear cleaning to prevent wax buildup.

3. Allergen Management: If your dog has allergies, work with your vet to manage them effectively. Allergies can contribute to ear issues.

4. Avoid Water Exposure: If your dog is prone to ear infections, try to keep their ears dry when bathing or swimming. Use cotton balls to block water from entering the ear canals.

5. Regular Vet Visits: Ensure that your dog receives regular check-ups with the veterinarian. Routine examinations can help catch and address ear problems early.

6. Proper Grooming: Maintain your dog's coat and grooming, especially around the ears, to prevent hair and debris from entering the ear canal.


Understanding the differences between dog ear mites and ear wax is crucial for the well-being of your furry friend. While both issues can cause discomfort and require attention, they have distinct causes, symptoms, and treatments. Ear mites are pesky parasites that require specific medication, while ear wax is a natural substance that may need regular cleaning if it accumulates excessively.


If you suspect your dog is experiencing ear problems, don't hesitate to seek veterinary care. A proper diagnosis and treatment plan can help alleviate your dog's discomfort and ensure their ears remain healthy and free from issues. Additionally, regular preventative measures, such as ear inspections and proper grooming, can go a long way in maintaining your dog's ear health and overall well-being. Remember, a happy, healthy dog starts with attentive care and knowledge of their unique needs.
