Definition of
Otitis externa is an inflammation of the outer ear canal in dogs. This condition can occur unilaterally or bilaterally and is a common cause of discomfort and pain in dogs.
Can Occur with the Following Diseases:
Grundlagen und mögliche Ursachen
The development of Otitis externa can be multifactorialMultifactorial refers to conditions or diseases that arise from the interplay of several causes or risk factors. In dogs and cats, these can be genetic predispositions, environmental influences, and nutritional factors that together lead to health problems., meaning that several factors can contribute to its development. Anatomical peculiarities of the dog’s ear, such as a narrow or elongated ear canal, can increase the risk of inflammation. Additionally, dogs with floppy ears may be more susceptible due to poor ventilation of the ear canal.
Allergies are a common cause of Otitis externa. Dogs can be allergic to various environmental allergens such as pollen, house dust mites, or certain foods. These allergic reactions lead to inflammatory conditions and excessive earwax production, which can result in blockage and infectionAn infection is the colonization and multiplication of pathogens such as bacteria, viruses, fungi, or parasites in an organism, which often, but not always, leads to a disease. of the ear canal.
Another cause can be parasites like ear mites. These small parasites are particularly common in young dogs and cause severe Itching and a dark brown, crumbly ear discharge. BacteriaBacteria are microscopic, single-celled organisms that exist in almost every environment on Earth. Some types of bacteria are beneficial or even essential to life, while others can cause disease. and yeasts are also common pathogens that can multiply rapidly in a moist and warm ear canal.
Injuries or foreign bodies in the ear can also cause inflammatory conditions. For example, if a dog gets plant material in its ear during a walk, this can lead to irritation and infections.
Typische Begleitsymptome
- Scratching the ear: Dogs with Otitis externa frequently and intensely Scratch their ears. This is often the first sign that pet owners notice.
- Head shaking: Repeated and vigorous head shaking can indicate discomfort or itching in the ear.
- Redness and Swelling: The ear canal may appear red and swollen, indicating inflammation.
- Discharge from the ear: An unpleasant odor or the discharge of fluid from the ear, which can be yellowish, brown, or bloody, often indicates an infectionAn infection is the colonization and multiplication of pathogens such as bacteria, viruses, fungi, or parasites in an organism, which often, but not always, leads to a disease..
- Sensitivity: Touching the ears can triggerA trigger is a stimulus that elicits a specific reaction or state. In veterinary medicine, this can refer to emotional responses, such as fear or aggression, or medical conditions, such as seizures in dogs and cats. pain reactions in affected dogs.
- Behavioral changes: Affected dogs may appear restless or irritable and may lose their appetite.
- Hearing loss: In severe cases, temporary or permanent hearing loss may occur.
Wann zum Tierarzt?
A veterinarian should be consulted as soon as the first signs of Otitis externa, such as intense Scratching or Head shaking, are noticed. Timely 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. and therapyTherapy refers to the treatment of diseases or disorders with the aim of alleviating symptoms, promoting healing, or improving quality of life. Therapies can be medicinal, surgical, or through other medical interventions. are crucial to avoid complications.
A veterinary visit is particularly important if the ear discharge has a strong odor or if the symptoms do not improve within a few days despite home care. Professional therapyTherapy refers to the treatment of diseases or disorders with the aim of alleviating symptoms, promoting healing, or improving quality of life. Therapies can be medicinal, surgical, or through other medical interventions. is also required for visible injuries or foreign bodies in the ear.
If the dog shows signs of pain or its behavior has changed significantly, a veterinarian should also be consulted immediately to prevent the condition from worsening.
Symptomerkennung für den Tierhalter und tierärztliches diagnostisches Vorgehen
Pet owners can recognize Otitis externa by looking for typical symptoms such as frequent Scratching and Head shaking. A visual inspection of the ear for redness, Swelling, or unusual discharge can also provide clues.
The veterinarian will perform a thorough examination of the ear, which includes an otoscopyOtoscopy is an examination of the ear canal and eardrum using an otoscope. It is performed to diagnose ear conditions, such as infections or foreign bodies., where the ear canal is examined using a special instrument. This allows for assessing the condition of the eardrum and the presence of foreign bodies or parasites.
Additionally, swabs of the ear discharge can be taken and examined microscopically to determine the type of infectionAn infection is the colonization and multiplication of pathogens such as bacteria, viruses, fungi, or parasites in an organism, which often, but not always, leads to a disease.

In some cases, a bacteriological culture may also be necessary to identify resistantResistant means being insensitive to a substance, drug, or treatment. In dogs and cats, resistance can refer to the ineffectiveness of antibiotics against certain bacterial strains or the insensitivity of parasites to certain pesticides. pathogens and choose the appropriate therapyTherapy refers to the treatment of diseases or disorders with the aim of alleviating symptoms, promoting healing, or improving quality of life.

Was kann der Tierhalter tun und professionelle Therapieoptionen
The pet owner can help alleviate the symptoms by gently cleaning the dog’s ears. However, only cleaning products recommended by the veterinarian should be used to avoid irritation.
It is important that the dog does not Scratch or rub its ears during therapyTherapy refers to the treatment of diseases or disorders with the aim of alleviating symptoms, promoting healing, or improving quality of life. Therapies can be medicinal, surgical, or through other medical interventions.. In some cases, a protective collar may be necessary to prevent this and support the healing process.
A balanced diet and avoiding known allergens can help reduce the tendency to inflammatory conditions in allergy-related Otitis externa. It is advisable to ask your veterinarian about a suitable diet or supplements.
Regular check-ups with the veterinarian are important to monitor the healing progress and to detect and treat possible relapses early on.

Another subject of current research is the development of diagnostic tools that enable earlier detection of Otitis externa. These include advanced imaging techniques and molecular tests that can provide a more accurate assessment of the severity of the inflammatory conditions. These innovations could enable veterinarians to better tailor treatment plans to the individual needs of the dog.
The effects of environmental factors such as climate and humidity on the occurrence of Otitis externa are also being investigated. Researchers are analyzing how seasonal changes and a dog’s geographical location could influence the risk of Otitis externa. The results of these studies could lead to preventive measures being adapted according to the dog’s place of residence.
