Increased ear secretion in dogs refers to the excessive production of earwax or other fluids in the ear canal, often associated with an infection, inflammation, or other health issues.

Can Occur with the Following Diseases:

Basics and possible causes

A dog’s ear consists of the outer, middle, and inner ear. The external auditory canal is a tubular structure that directs sound waves to the eardrum. Earwax, also called cerumen, is produced in the ear glands and has a protective function by trapping dirt and foreign objects.

Compared to humans, dogs have a deeper and longer ear canal, making them more prone to ear problems. Increased ear secretion can be caused by an overproduction of earwax or by fluid accumulation due to inflammation or infection.

Possible causes of increased ear secretion include infections from bacteria or yeast, allergies, foreign objects in the ear, mite infestations, and hormonal disorders. Anatomical features, such as in dogs with floppy ears, can also impair the ventilation of the ear canal and increase the risk of disease.

Typical accompanying symptoms

  • Itching: Dogs often scratch their ears or rub their head on furniture or the floor, indicating an uncomfortable feeling or itching in the ear.

  • Odor: An unpleasant or foul odor from the ear may indicate a bacterial or fungal infection.

  • Redness and Swelling: The skin in and around the ear canal may be red and swollen, indicating inflammation or infection.

  • Head shaking: Frequent head shaking may indicate that the dog is trying to remove an uncomfortable feeling or fluid from the ear.

  • Pain: The dog may react sensitively or show pain when touching the ears or head.

When to visit the vet?

A veterinarian should be consulted if the ear secretion is accompanied by one or more of the aforementioned symptoms, especially with signs of pain, severe itching, or a foul odor. Early diagnosis and treatment can prevent the progression of the disease and provide relief to the dog.

Even if the symptoms appear mild, but persist for more than a few days, a visit to the veterinarian is advisable. This is especially true if the dog repeatedly suffers from ear problems, as this may indicate chronic or recurrent causes that require specific treatment.

Symptom recognition for animal owners and veterinary diagnostic procedures

It is important for the pet owner to pay attention to changes in the dog’s behavior, such as frequent Scratching ears, head shaking, or an unpleasant odor. These signs may indicate ear problems.

The veterinarian will first perform a clinical examination, during which the dog’s ears are thoroughly inspected. An otoscope can be used to better view the ear canal and eardrum. Swabs from the ear can be taken to perform microscopic examinations and determine if bacteria, yeasts, or mites are present.

In some cases, additional diagnostic tests may be required, such as X-rays or a computed tomography scan, to identify deeper problems, especially if otitis media is suspected.

What can pet owners do and professional therapy options

As a first step, the pet owner can try to gently clean the dog’s ears with a soft cloth to remove excess secretions and dirt. However, it is important to avoid cotton swabs, as these can worsen the problem by pushing the earwax deeper into the ear canal.

There are special ear cleaning agents for dogs that can help keep the ear clean. However, these should only be used after consulting with a veterinarian to ensure that they are suitable for the specific condition of the dog.

To avoid major damage, you should never try to reach deep into the ear canal or perform treatments yourself that have not been recommended by a veterinarian. Improper treatment can lead to injury or worsening of the infection.

To improve the dog’s well-being, soothing measures, such as avoiding loud noises and stressful situations, can also be helpful until professional treatment is provided.

Outlook on current research

Research on increased ear secretion in dogs focuses on various aspects, including the causes, diagnostic methods, and treatment options. A significant portion of current studies examines the role of bacteria and yeasts, especially Malassezia, which are often found in ears with excessive secretion growth. Researchers analyze the specific microbial communities in the ear canal of dogs to gain a better understanding of the microbial dysbiosis that can lead to increased secretion.

Another important area of research is the development and improvement of diagnostic techniques. Traditionally, the examination of ear secretion is performed by microscopic analysis, but new, less invasive methods are being explored to make the diagnosis faster and more accurate. For example, the use of molecular diagnostic tests and DNA sequencing technologies is being investigated to better identify specific pathogenic organisms in the ear.

Treatment strategies are also a key focus of research. While antibiotics and antifungals are often prescribed, their effectiveness is impaired by the emergence of resistant strains. As a result, researchers are investigating alternative treatment approaches, including the use of probiotics to promote microbial balance in the ear, as well as the development of new topical medications that are less susceptible to resistance problems.

In addition, there are efforts to develop preventive measures that reduce the risk of increased ear secretion. These include nutritional studies that examine the role of nutrients and supplements in supporting ear health, as well as environmental studies that analyze the effects of allergens and other external factors on the ear health of dogs.

Long-term studies are also investigating the genetic factors that contribute to the susceptibility of certain dog breeds to ear problems. This research could lead to breeding programs in the future that minimize the risk of increased ear secretion by identifying and addressing genetic predispositions.

Frequently asked questions

  1. What does increased ear secretion mean in dogs? Increased ear secretion in dogs refers to an excessive production of earwax or other fluids in the ear canal, which is often visible and sometimes associated with an unpleasant odor.

  2. What signs indicate increased ear secretion? Signs may include increased head shaking, Scratching ears, redness, Swelling, or an unpleasant odor from the ear. The presence of visible secretion is also often noticed.

  3. How can increased ear secretion be diagnosed in dogs? Diagnosis is usually made by an examination by a veterinarian, who inspects the ear and may take a sample of the secretion to analyze it microscopically or through other tests.

  4. What are the possible causes of increased ear secretion? Causes can include infections from bacteria or fungi, allergies, foreign objects in the ear, genetic predisposition, or parasites such as ear mites.

  5. How is increased ear secretion treated? Treatment depends on the cause and may include cleaning the ear, applying antibiotics or antifungals, making changes to the diet, or using medications to control allergies.

  6. Can increased ear secretion be prevented in dogs? Prevention can be achieved through regular cleaning of the ears, avoiding allergens, and paying attention to a balanced diet. Regular veterinary visits to check ear health are also important.

  7. Are there certain dog breeds that are more prone to ear problems? Yes, breeds with long, floppy ears such as Cocker Spaniels, Basset Hounds, and Labradors are often more prone to ear problems, including increased secretion, due to the limited air circulation in the ear.

  8. What happens if increased ear secretion is not treated? If left untreated, increased ear secretion can lead to chronic ear infections, pain, hearing loss, and in severe cases, spread of the infection to other areas.

  9. Can home remedies help against increased ear secretion? While some home remedies may help, it is advisable to consult with a veterinarian before using them, as improper treatments can worsen the problem.

  10. How often should you clean a dog’s ears? The frequency of cleaning depends on the breed and the individual needs of the dog. As a rule, it is sufficient to check the ears once a week and clean them if necessary. More frequent cleaning may be necessary for dogs with a known tendency to ear problems.
