Scratching the ear in dogs is a common behavior that indicates the dog is experiencing an uncomfortable sensation or irritation in or around the ear. This behavior can range from mild discomfort to serious medical problems.

Can Occur with the Following Diseases:

Basics and possible causes

Scratching the ear can be triggered by various factors affecting the outer ear, ear canal, or middle ear. The dog’s outer ear consists of the auricle and the external auditory canal, while the middle ear and inner ear are located deeper in the head. The ear is a sensitive organ that can easily be irritated by external influences or internal diseases.

One of the most common causes of itching and scratching the ear is an ear infection, also called otitis. This can be caused by bacteria, yeast, or parasites such as ear mites. Ear mites are tiny, parasitic insects that live in the ear and can cause inflammation and itching. Yeast and bacteria often thrive in moist conditions and can multiply in the ears of dogs, especially in breeds with long, drooping ears.

Allergies are another common cause of ear problems in dogs. Dogs can be allergic to various substances, including pollen, house dust mites, certain foods, or grooming products. These allergies can lead to an inflammatory reaction in the skin, which also affects the ears.

Other less common causes may include foreign objects in the ear, such as grass awns, or tumors in the ear area. Hormonal disorders or autoimmune diseases can also affect the ear and cause itching.

Typical accompanying symptoms

  • Ear discharge: An abnormal, often foul-smelling discharge from the ear can be a sign of an infection or the presence of ear mites.
  • Redness and swelling: A reddened and swollen auricle or an inflamed ear canal indicate irritation or infection.
  • Head shaking: Dogs who frequently shake their heads may be trying to relieve the itching or get rid of a foreign object.
  • Odor: An unpleasant odor from the ear may indicate a bacterial or yeast infection.
  • Frequent rubbing of the head: Dogs that rub their head on furniture or the floor may be trying to relieve the itching.
  • Loss of balance: In severe cases, inflammation of the inner ear can affect the dog’s balance.
  • Hearing loss: A reduced response to noises or complete hearing loss can occur if the infection reaches the inner ear.

When to visit the vet?

A veterinarian should be consulted if scratching the ear persists for more than a few days or if other symptoms such as discharge, redness, swelling, or an unpleasant odor occur. These signs indicate that there is an underlying infection or other serious problem that needs to be treated.

Also, if the dog shows signs of pain, such as whining when touching the ear or if he frequently holds his head tilted, a visit to the veterinarian is urgently needed. Pain and a tilted head can indicate a deeper infection or a problem in the inner ear.

If the dog shows balance disorders or signs of disorientation, a veterinarian should be consulted immediately. These symptoms may indicate a serious condition of the inner ear that requires immediate treatment.

Symptom recognition for animal owners and veterinary diagnostic procedures

The pet owner can recognize early signs of ear problems by regularly inspecting their dog’s ears. Look for redness, swelling, discharge, or an unpleasant odor. Behavioral changes such as frequent head shaking or scratching the ear should also be noted.

The veterinarian will perform a thorough examination of the ear, often with an otoscope. This instrument allows to inspect the ear canal and eardrum. If necessary, the veterinarian can take samples of the ear secretion to test for bacteria, yeast, or mites. These samples can be examined microscopically or sent to a laboratory for further analysis.

In some cases, an X-ray or other imaging examination may be necessary to better assess the extent of an infection or other problems in the ear.

The veterinarian will also assess the dog’s general health and may perform blood tests to rule out other underlying health problems that could be affecting the ear.

What can pet owners do and professional therapy options

As a first measure, the pet owner should avoid cleaning or treating the dog’s ear themselves without first seeking the advice of a veterinarian, as this could worsen the situation. Improper cleaning can cause injury or worsen an existing infection.

If the dog feels uncomfortable, the owner can try to prevent him from scratching or rubbing the affected ear to avoid further injury. A soft collar or Elizabethan collar can help prevent access to the ear.

It is important to follow the veterinarian’s instructions exactly when medications or special cleaning agents are prescribed. Regular use of prescribed drops or ointments can help fight the infection and relieve the itching.

In addition, the pet owner can try to keep the dog’s environment clean and dry to reduce the risk of ear infections. Especially dogs with long, drooping ears should be thoroughly dried after bathing or swimming.

A balanced diet and the avoidance of allergens can also help to avoid ear problems. If the dog suffers from allergies, the veterinarian may recommend special hypoallergenic feeds or dietary supplements.

Outlook on current research

Current research in veterinary medicine shows that scratching the ear in dogs is a common symptom that can indicate a variety of underlying problems. Studies have shown that allergies, both environmental and food-related, are one of the most common causes. Recent developments in diagnostic methodology have led to veterinarians now offering specific allergy tests that help identify the exact cause of itching and scratching. This has led to an improved treatment strategy that is individually tailored to the needs of the dog.

Another area of intensive research concerns the role of microorganisms in the dog’s ear. Studies have shown that an imbalance of bacteria and yeast in the ear can lead to inflammation and itching. Through the use of DNA sequencing techniques, researchers have been able to create a detailed map of the microbial landscape in the ears of dogs, leading to more targeted treatment approaches. These approaches often involve the use of probiotics to restore the natural balance.

In behavioral research, scratching the ear is increasingly seen as an expression of stress or boredom. Scientists are working to recognize the subtle differences between pathological and behavioral causes. Research projects that focus on improving the quality of life of dogs through environmental enrichment and training show promising results. These projects aim to address not only the physical but also the psychological causes of scratching.

Another promising area of research involves the development of new topical treatments specifically targeting the relief of itching and inflammation. Many of these new products are based on natural ingredients such as oat extract and aloe vera, which are known for their soothing properties. Clinical studies show that these natural treatments are often similarly effective as their chemical counterparts, but with fewer side effects.

In summary, research in the field of scratching the ear in dogs continues to advance, with a focus on both identifying specific causes and developing effective and gentle treatment strategies. By combining state-of-the-art diagnostic techniques and innovative therapies, it is becoming increasingly possible to significantly improve the well-being and quality of life of dogs.
