Hair loss at the ear margins in dogs, also known as “ear margin alopecia,” is a condition in which dogs lose hair on the edges of their ears. This condition can be both aesthetically disturbing and indicative of underlying health issues.
Can Occur with the Following Diseases:
Grundlagen und mögliche Ursachen
Hair loss in dogs can be caused by a variety of factors, ranging from harmless to serious health problems. The ear margins are particularly prone to hair loss because they have less blood flow and the skin is thinner there.
One of the most common causes of hair loss at the ear margins is a genetic predispositionA predisposition is an innate inclination or susceptibility of an organism to certain diseases or conditions. In dogs and cats, there may be a genetic predisposition to certain conditions such as hip dysplasia or certain heart diseases.. Certain breeds such as Dobermans, Chihuahuas, and Dachshunds are more susceptible to this type of hair loss. This genetic predispositionA predisposition is an innate inclination or susceptibility of an organism to certain diseases or conditions. In dogs and cats, there may be a genetic predisposition to certain conditions such as hip dysplasia or certain heart diseases. means that in many cases, the hair loss cannot be completely prevented.
Another common cause is hormonal imbalanceImbalance refers to an imbalance or disruption of normal function or composition in the body, which can lead to health problems., especially in dogs with hypothyroidism or Cushing’s syndromeA syndrome is a group of symptoms that occur together and indicate a specific disease or condition. A syndrome can be caused by various factors and is often complex in its diagnosis and treatment.. These conditions affect the dog’s hormoneHormones are chemical messengers produced by endocrine glands and released into the bloodstream to affect specific cells or organs in the body. They regulate numerous bodily functions, including growth, metabolism, and reproduction. balance and can lead to hair loss.
Allergies are also a common cause of hair loss. Dogs can be allergic to food, pollen, house dust mites, or other environmental factors. These allergies can lead to itching and scratching, which can ultimately result in hair loss.
Parasites such as fleas, mites, or ticks can also cause hair loss by irritating the skin and causing inflammatory conditions. These parasites can live on the skin’s surface and cause inflammatory conditions and itching, leading to hair loss.
Infections, both bacterial and fungal, can also affect the health of the skin and cause hair loss. Such infections can arise through open wounds or through contact with infected animals or surfaces.
Typische Begleitsymptome

- Itching: If a dog constantly scratches or rubs its ears, this may indicate itching, which is often associated with hair loss.
- Scaling: Dry, scaly skin at the ear margins can also be a sign of skin problems that lead to hair loss.
- Changes in skin pigmentation: Darker or lighter spots on the skin can also occur and are often an indicationIndication refers to a valid reason or rationale for using a specific treatment, medication, or medical procedure.

- Open Wounds or Crusts: In cases of severe itching or infections, open wounds or crusts may develop, which also promote hair loss.
Wann zum Tierarzt?
A visit to the veterinarian should be considered if the hair loss occurs suddenly or worsens. A veterinary examination is also advisable if accompanying symptoms such as redness, itching, or swelling are present.
If the dog additionally shows other symptoms such as lethargy, loss of appetite, or unusual behavior, this could indicate a more serious underlying condition that requires immediate veterinary care.
A vet visit is also necessary if no obvious external causes such as parasites or injuries can be identified, in order to ensure a comprehensive diagnosisA diagnosis is the identification of a disease or condition by its symptoms and/or results from diagnostic tests. It is the first step in the management and treatment of patients..

It is important for the pet owner to recognize the hair loss early. An initialInitial means beginning or at the start. In medicine, it can refer to the first symptoms of a disease or the first phase of a treatment process. indicationIndication refers to a valid reason or rationale for using a specific treatment, medication, or medical procedure. It is based on the diagnosis and the patient's clinical condition. may be increased scratching or rubbing of the ears. A close look at the ear margins to detect redness, scaling, or other skin changes is helpful.
The dog will undergo a thorough physical examination at the veterinarian. Here, the ears and the entire skin of the dog are examined for signs of parasites, infections, or other skin diseases.
In addition, specific tests such as skin scrapings, blood tests, or allergyAn allergy is an overreaction of the immune system to a normally harmless substance, the allergen. The reaction can include symptoms such as skin rash, itching, sneezing, respiratory distress, or in severe cases, anaphylactic shock. tests can be performed to determine the exact cause of the hair loss. A skin scraping can help identify parasites or fungal infections, while blood tests can provide information about hormoneHormones are chemical messengers produced by endocrine glands and released into the bloodstream to affect specific cells or organs in the body. They regulate numerous bodily functions, including growth, metabolism, and reproduction. levels and any allergic reactions.
In some cases, a biopsyA biopsy is a medical procedure in which a small amount of tissue is removed from the body to be examined under a microscope for signs of disease. Biopsies can help diagnose cancer and other conditions. of the skin may also be necessary to rule out more serious diseases or to make an accurate diagnosisA diagnosis is the identification of a disease or condition by its symptoms and/or results from diagnostic tests.

Was kann der Tierhalter tun und professionelle Therapieoptionen
The pet owner can take some immediate steps to alleviate the condition and prevent further damage. Regular checking and cleaning of the ears can help prevent infections and build-up of dirt or wax.
It is important to prevent the dog from excessive scratching or rubbing of the ears to avoid additional damage or infections. This can be achieved by putting on a protective collar or distracting the dog with toys or activities.
If parasites are suspected, appropriate agents should be used to control fleas, mites, or ticks. It is advisable to seek advice from a veterinarian to choose a safe and effective product.
The dog’s diet can also play a role. A balanced diet rich in essential fatty acids can contribute to the health of the skin and potentially reduce hair loss. Special nutritional supplements or a change of feed can be considered in consultation with the veterinarian.
Finally, it is important to observe the dog regularly and consult the veterinarian if there is a suspicion of a worsening of the symptoms or the occurrence of new symptoms in order to ensure appropriate treatment.
Ausblick auf aktuelle Forschung
Hair loss at the ear margins in dogs is a symptom that is receiving increasing attention in veterinary research. Scientists are investigating various aspects to better understand why and how this symptom occurs, and to develop targeted treatment strategies. A key focus is on the investigation of genetic factors, as certain breeds, such as the Doberman or Dachshund, appear to be more frequently affected.
