Crusts on the edges of the ears, ankles, armpit, and elbows in dogs is a symptom that can indicate various skin diseases or systemic problems. It involves the formation of hard, often scaly deposits on the skin, which can be triggered by various causes.

Can Occur with the Following Diseases:

Basics and possible causes

A dog’s skin is its largest organ and serves as a barrier against environmental influences, protects against infections, and regulates body temperature. Healthy skin is elastic, smooth, and free of lesions. However, if the skin is damaged, a variety of symptoms can occur, including the formation of crusts.

Crusts form when the skin is damaged and the body tries to repair this injury by producing additional skin cells. This process can be triggered by infections, allergic reactions, parasite infestations, or autoimmune diseases.

One of the most common causes of crusts is an infection caused by bacteria, fungi, or viruses. Bacterial skin infections, such as pyoderma, can be favored by a variety of factors, including allergic reactions or a weakened immune system. Fungal infections, such as ringworm, are highly contagious and can also lead to the formation of crusts.

Allergies triggered by environmental factors, food, or parasites such as fleas can also cause skin irritation and crusts. Allergic reactions often cause severe itching, which can lead to further skin damage through scratching or biting.

Parasite infestations, especially by mites (e.g., mange), can lead to intense crusts. These microorganisms penetrate the skin and cause severe inflammatory conditions and skin changes.

Autoimmune diseases, in which the immune system attacks the body’s own tissues, can also cause crusts. Examples include diseases such as pemphigus foliaceus, in which the skin cells detach from each other and form scaly crusts.

Typical accompanying symptoms

  • Itching: Often accompanied by crusts is severe itching, which leads to increased scratching and licking, which can further damage the skin.

  • Redness and inflammation: The affected skin areas are often red and swollen, indicating an inflammatory reaction of the body.

  • Hair loss: In areas with crusts, local hair loss may occur because the hair follicles are damaged by the inflammatory conditions.

  • Pain: In cases of severe inflammation or infection, the affected areas can be painful, which the dog shows through insensitivity to touch or withdrawal.

  • Odor: Infected or inflamed skin can develop an unpleasant odor, which may indicate a secondary bacterial infection.

  • Changes in behavior: Dogs with skin problems may withdraw, appear lethargic, or show increased aggression, especially if the skin is painful.

When to visit the vet?

A visit to the veterinarian is essential if the crusts is accompanied by severe itching, redness, inflammation, or other systemic symptoms such as fever or loss of appetite. These signs may indicate a serious infection or a systemic disease that requires immediate treatment.

If the crusts occurs suddenly or worsens rapidly, a veterinarian should also be consulted to ensure accurate diagnosis and appropriate treatment.

If there are indications of parasite infestation, such as crusts together with small, moving dots on the skin or in the dog's coat, an immediate veterinary visit is also necessary.

If the dog shows signs of pain or the affected skin areas are very sensitive, this should also be a reason to consult a veterinarian. Pain can be an indicator of a deeper infection or a serious inflammatory condition.

Symptom recognition for animal owners and veterinary diagnostic procedures

The detection of crusts and the associated symptoms can be done by the pet owner through regular examination of the dog’s skin. It is important to pay attention to changes in the texture, color, and odor of the skin, as well as the dog’s behavior, which may indicate discomfort.

The veterinarian will first perform a thorough clinical examination to determine the cause of the crusts. This includes inspection of the affected skin areas as well as a general health check to rule out systemic problems.

Skin scrapings, biopsies, or blood tests may be necessary for diagnosis. A skin scraping can help identify bacteria, fungi, or parasites, while a biopsy can provide information about possible autoimmune diseases. Blood tests can provide clues to allergic reactions or systemic diseases.

In addition, allergy tests can be performed to identify potential allergens that may be causing the skin reaction. An accurate diagnosis is crucial to determine the correct treatment strategy.

What can pet owners do and professional therapy options

To alleviate the dog’s discomfort, the owner should first ensure that the dog does not continue to scratch or lick the affected areas. This can be achieved by applying a neck brace or using protective clothing to promote skin healing.

Gently cleaning the affected skin areas with a damp cloth or a mild antiseptic shampoo can help remove the crusts and prevent infections. However, it is important to do this in consultation with the veterinarian to avoid further irritating the skin.

The dog’s diet should be checked to ensure that it contains all the necessary nutrients needed for healthy skin. A balanced diet can strengthen the immune system and promote skin health.

Depending on the cause of the crusts, the veterinarian may prescribe medications such as antibiotics, antifungals, or antiparasitic agents. These should be administered exactly as directed to support healing and prevent relapses.

In cases where allergies are the cause, the veterinarian may recommend a hypoallergenic diet or special allergy medications to control symptoms and prevent further skin damage.

Outlook on current research

Crusts on the edges of the ears, ankles, armpit, and elbows of dogs is a symptom that is receiving increasing attention in veterinary medical research. Scientists are investigating the molecular and cellular mechanisms that lead to this type of skin changes in order to better understand how they can be diagnosed and treated. One of the most significant advances in research is the identification of genetic markers associated with certain skin diseases that can cause crusts. These discoveries facilitate the development of genetic tests that help in the early detection and management of the underlying diseases.

Another current focus is on the role of the immune system in the development of skin diseases that lead to crusts. Researchers are investigating how inflammatory conditions, involving cytokines and other immune cells, affect skin health. By understanding these immunological processes, new therapeutic approaches can be developed that aim to reduce inflammation and strengthen the skin barrier. These approaches could be particularly important in autoimmune-related diseases.

Environmental factors and their impact on the skin health of dogs are also a significant research topic. Scientists are analyzing how environmental allergens, such as pollen or house dust mites, can promote the development of skin irritation and crusts. The findings from these studies could lead to improved environmental management strategies that help minimize the risk of skin problems in dogs. In addition, the effect of nutrition and micronutrients on skin health is being investigated to determine how dietary adjustments can contribute to the prevention or alleviation of crusts.

In clinical research, various therapeutic approaches are being tested to treat crusts and their causes. These range from topical treatments applied directly to the affected skin areas to systemic therapies that affect the entire organism. The use of biologics, which modulate specific immune pathways, is a particularly promising area being investigated in clinical trials. The goal is to develop more effective and safer treatment options that improve the quality of life of dogs with skin problems.

Advances in imaging technology are also contributing to research by enabling more detailed and precise diagnoses. High-resolution imaging techniques such as dermatoscopy and confocal laser microscopy are used to examine skin structure and function in real time. These technologies help veterinarians detect subtle changes in the skin that may indicate an underlying condition and allow for more individualized treatment planning.

In summary, current research initiatives are helping to deepen the understanding of the mechanisms of crusts in dogs and to advance the development of innovative diagnostic and treatment strategies. The integration of genetic, immunological, and environmental insights is expected to play a crucial role in improving the skin health and well-being of dogs.
