Moist lesions at the ear margins in dogs are open, often moist skin lesions that develop along the edges of the animal’s ears. These wounds can be bloody, purulent, or serous and tend to be caused or worsened by friction or scratching.

Can Occur with the Following Diseases:

Basics and possible causes

A dog’s ear skin is particularly sensitive and susceptible to various damaging influences. Moist lesions at the ear margins can be caused by a variety of factors, ranging from external irritants to systemic health problems. The ears are highly vascularized and have many nerve endings, making them particularly sensitive to pain and responsive to stimuli.

A common cause of moist lesions is ear margin necrosis, which is caused by impaired blood flow to the ear margins. This can be genetic or caused by vascular problems. In addition, allergies, both environmental and food allergies, can play a role, as they can cause itching and inflammatory conditions.

Parasites such as fleas, mites, or ticks are also common causes of skin irritation on the ears. For example, an ear mite infestation can trigger severe itching, which causes the animal to scratch and rub, which in turn can lead to injuries and moist lesions.

Bacterial or fungal infections can also cause inflammatory conditions and moist lesions. These microorganisms find ideal growth conditions in the moist and warm environment of the ears. They can occur either primarily or secondarily as a result of injuries or other skin problems.

In addition, hormonal disorders, such as hypothyroidism or Cushing’s syndrome, can weaken the immune system and impair the skin barrier, leading to increased susceptibility to skin problems. Traumatic injuries from pulling or biting can also cause initial damage that then becomes infected and moist.

Typical accompanying symptoms

  • Itching: Frequent scratching or rubbing of the ears, which can worsen the wounds.
  • Swelling: The ear margins may be swollen and reddened, indicating an inflammatory condition.
  • Bleeding: In some cases, the wounds may bleed, especially if they are scratched open.
  • Odor: An unpleasant odor may emanate from the wounds, which could indicate an infection.
  • Pain sensitivity: The dog may pull back or show discomfort when the ears are touched.
  • Crusts and scabs: Crusts or scabs often form on the wounds, but they can easily break open again.
  • Frequent Head shaking: The dog shakes its head to relieve the discomfort, which can worsen the wounds.

When to visit the vet?

A visit to the veterinarian is essential if the moist lesions do not heal within a few days or worsen. If the dog also shows signs of pain, fever, or lethargy, urgent action should be taken. Professional help is also required if the dog is excessively itchy or scratching, which could lead to further injury.

A veterinarian should also be consulted immediately if there are signs of an infection, such as pus or a strong odor. Timely diagnosis and treatment are crucial to clarify the cause and initiate appropriate therapy. Untreated wounds can spread and lead to more serious health problems.

Symptom recognition for animal owners and veterinary diagnostic procedures

It is important for the pet owner to recognize the symptoms early. Pay attention to changes in your dog’s behavior, especially frequent scratching, head shaking, or signs of pain. Regular inspections of the ears and ear margins help to identify problems early.

The veterinarian will first take a thorough medical history and perform a clinical examination of the dog. The ears are carefully inspected to assess the degree of damage and possible signs of infection. A smear can be taken to test microscopically for bacteria or fungi.

In addition, a blood test can be performed to identify systemic causes such as hormonal imbalances or allergies. In some cases, a biopsy of the tissue is necessary to rule out or confirm specific skin diseases.

In the case of parasite infestation, the veterinarian may also recommend an examination for fleas, mites, or other ectoparasites. Ultrasound or X-rays may be necessary to examine deeper structures if a systemic disease is suspected.

What can pet owners do and professional therapy options

As a first measure, the pet owner can try to gently clean the affected area with a mild antiseptic solution to remove dirt and germs. Be sure to use products that are specifically suitable for dogs to avoid further irritation.

To relieve the itching, cold compresses can be helpful. However, these should not be placed directly on the open wound, but wrapped in a clean cloth. The pet owner should make sure that the dog does not scratch or bite its ears, as this can worsen the wounds. A protective collar can be used to prevent this.

Feeding a balanced, hypoallergenic diet can also help if a food allergy is suspected. It is important to coordinate the diet with the veterinarian to ensure that all of the dog’s nutritional needs are met.

If the moist lesions do not heal or worsen despite home care, it is crucial to seek professional veterinary help to ensure that the correct diagnosis is made and appropriate treatment is initiated.

Outlook on current research

Research in the field of moist lesions at the ear margins in dogs has made significant progress in recent years. Scientists are investigating the biological processes that lead to such exudation. One of the main theories is that the moist lesions are often caused by a combination of environmental factors and genetic predispositions. Specifically, research is being conducted into how certain breeds or dogs with genetic markers are more susceptible to skin irritation and secondary infections. Studies suggest that a disturbed barrier function of the skin on the ear margin could play a role, with research increasingly focusing on the role of keratin and lipids in the skin.

Furthermore, research is being conducted into the extent to which the dog’s immune system reacts to microbial influences in the environment. It is suspected that an overreaction of the immune system can lead to a worsening of the symptoms. Current studies are analyzing the immune responses of dogs with moist lesions in order to better understand how specific immune cells and cytokines are involved. These findings could lead to more targeted therapeutic approaches in the future that modulate the immune system to promote healing.

Another area of research is concerned with the role of microorganisms in the environment of the ear margins. The microflora of the skin is analyzed in detail to find out which bacteria or fungi are present in higher concentrations in affected dogs. By understanding the microbial environment, preventive measures could be developed to reduce the occurrence or severity of the moist lesions. This could be done, for example, through the development of probiotic ointments or special shampoos that have a positive effect on the skin flora.

Materials science also contributes to research by developing new, skin-friendly materials for protective devices and bandages. These materials are designed to promote healing by regulating moisture while providing a protective barrier against external influences. Initial prototypes of such materials are already in clinical trials and show promising results in terms of reducing exudation and accelerating healing.

Overall, current research shows that a multidisciplinary approach that combines genetics, immunology, microbiology, and materials science has the potential to provide new insights and treatment approaches for moist lesions at the ear margins in dogs. In the long term, this research could not only improve the treatment of these symptoms but also expand the understanding of related dermatological problems in dogs.
