Definition of

Dandruff in dogs—also known as Scaling or seborrhea—refers to the shedding of dead skin cells that become visible as small, dry skin particles. They can be found on the dog’s coat or in the environment and are often a sign of an underlying health issue.

Can Occur with the Following Diseases:

Grundlagen und mögliche Ursachen

A dog’s skin consists of several layers, with the outermost layer—the epidermis—being constantly renewed. In a healthy process, dead skin cells are continuously replaced by new ones. However, if this process is disrupted, an excessive buildup of dead skin cells can occur, which shows up as dandruff.

There are many factors that can lead to increased Scaling. Commonly, environmental factors such as dry air or frequent bathing with unsuitable shampoos can dry out the skin. Nutritional deficiencies—especially a lack of essential fatty acids or certain vitamins—can also contribute to the skin not functioning optimally.

Another common cause is allergies, which can be triggered by food as well as environmental substances such as pollen or house dust mites. These allergens can cause Inflammatory conditions and irritation, weakening the skin barrier and leading to Scaling.

Parasites such as fleas, mites, or lice are also common triggers. They not only cause mechanical irritation through biting or stinging, but can also 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. allergies that further damage the skin.

Diseases such as 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. can also lead to skin problems because they affect the dog’s metabolism and therefore the health of the skin.

Typische Begleitsymptome

Itching: Dogs with scaly skin often show increased scratching or biting at affected areas, indicating itching.
Redness: The skin may be reddened, indicating an inflammatory conditions or irritation.
Hair loss: In connection with scaling, there may be excessive hair loss.
Odor: An unpleasant smell may indicate 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. or excessive sebumsebum is the oily substance produced by the skin's sebaceous glands. It helps keep the skin and hair supple and provides some protection against bacteria and fungi. production.
Crusts: In some cases, crusts or thick layers of dead skin may form.

Wann zum Tierarzt?

Eskalation: ORANGE for severe Itching with self-trauma, pustular/foul-smelling Lesions, Fever/apathy, or rapid spread (/severe dermatitis).

A veterinary visit is necessary if the Scaling starts suddenly or is accompanied by other symptoms such as severe Itching, open Wounds, or Hair loss. Even if the dog shows signs of discomfort or its behavior changes, a veterinarian should be consulted.

A visit to the veterinarian is particularly important if the scaling does not improve despite good care and nutrition, as this may indicate a serious underlying problem.

Symptomerkennung für den Tierhalter und tierärztliches diagnostisches Vorgehen

Pet owners can spot early signs of Scaling by regularly checking their dog’s coat for white particles or skin irritation. Increased Scratching or Licking can also be a sign.

The veterinarian will first take a thorough medical historyThe medical history is the systematic collection of a patient's medical history through questioning. It includes information about previous illnesses, treatments, allergies, and lifestyle habits. to narrow down possible causes. This includes assessing the dog’s eating habits, grooming routine, and environment. A physical examination will be carried out to assess the overall state of health.

In some cases, diagnostic tests such as skin swabs, 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 may be required to identify specific causes such as parasites, 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., or hormonal imbalances.

Was kann der Tierhalter tun und professionelle Therapieoptionen

If Scaling is detected, the pet owner should first review the dog’s diet. A balanced diet with enough essential fatty acids and vitamins can help improve skin health. If needed, the diet should be adjusted in consultation with a veterinarian.

Using a mild, moisturizing dog shampoo can help soothe the skin and reduce Scaling. It is important not to bathe the dog too often so as not to destroy the skin’s natural protective layer.

Regular brushing of the coat can help remove dead skin cells and promote skin circulation, which supports skin health.

If there are signs of a parasiteA parasite is an organism that lives on or in another living being (the host) and feeds at its expense. Parasites can cause a variety of diseases in animals and humans. infestation, appropriate antiparasitic treatments should be used, selected in consultation with a veterinarian. Preventive measures such as regular flea and tick checks are also important.

If allergies are suspected, the pet owner can try to identify and eliminate possible allergens. This may include switching to hypoallergenic food or avoiding certain environmental factors.

Ausblick auf aktuelle Forschung

Current research into scaly skin in dogs is examining many aspects, including the underlying biochemical processes that lead to Scaling. Scientists are analyzing the role of keratinocytes—the main cells of the epidermis—and their rate of keratin production, a key proteinProteins are large molecules made up of amino acids and play an essential role in almost all biological processes. They are necessary for building body tissue, the function of the immune system, and as enzymes for metabolic reactions. in the skin. Increased or disrupted keratin production can lead to excessive Scaling. One study showed that certain genetic factors in dogs can contribute to excessive keratinization of the skin. These genetic predispositions are still being researched to better understand which breeds are particularly susceptible.

Another important area of research focuses on the role of the skin microbiome in dogs. Studies have shown that an imbalanceImbalance refers to an imbalance or disruption of normal function or composition in the body, which can lead to health problems. in the normal skin flora—affected by factors such as diet, environment, or stress—can contribute to Scaling. New probiotic and prebiotic supplements are being tested to see whether they can positively influence the skin microbiome and thus reduce Scaling.

Research is also examining the influence of nutrition on skin health. There is evidence that fatty acids—especially omega-3 and omega-6 fatty acids—play a crucial role in maintaining a healthy skin barrier. Studies are exploring how specialized diets and supplements can help improve skin health. Experiments with different diets aim to find out which nutrient combinations are most effective at reducing Skin dry and Scaling.

In addition, new therapeutic approaches are being developed to treat scaly skin in dogs. Researchers are testing topicalTopical refers to the direct application of medications or treatments to the skin or mucous membranes for a local effect, without being absorbed into the body. treatments that moisturize and strengthen the skin barrier. These include innovative formulations with natural oils and plant extracts. New medications are also being developed that specifically affect the cell division and differentiation of epidermal cells to reduce Scaling.

Another interesting area of research is the investigation of psychologicalPsychological refers to anything related to the mind or behavior. In veterinary medicine, this can include the study of animal behavior, including stress responses and behavioral disorders. factors that may contribute to skin Scaling. StressStress refers to the state of an organism reacting to external stimuli or demands. In veterinary medicine, stress can have physical or psychological effects on animals, impacting their health and well-being. and anxiety in dogs are suspected of negatively affecting skin health. Studies are analyzing how behavior modification and stressStress refers to the state of an organism reacting to external stimuli or demands. In veterinary medicine, stress can have physical or psychological effects on animals, impacting their health and well-being. management—such as the use of pheromone therapies—may help relieve the symptoms of skin Scaling.
