Grundlagen und mögliche Ursachen
Hair loss in dogs can be triggered by a variety of factors. The most common causes include allergies, parasites, infections, and hormonal imbalances. Dogs can be allergic to various environmental factors, foods, or Contact substances, which can lead to itching and hair loss.
Parasites such as fleas, mites, or lice can also cause skin irritation. These parasites feed on skin cells or blood, leading to itching and Inflammatory conditions. The dog’s reaction to this itching often causes further hair loss, as the dog scratches or bites to relieve the Itching.
Infections, both bacterial and fungal, can also lead to hair loss. These infections can be favored by injuries to the skin or by a weakened immune systemThe immune system is the body's defense system against infectious agents such as bacteria, viruses, fungi, and parasites. It comprises a complex network of organs, cells, and molecules that work together to protect the body.. One of the most common fungal infections that leads to hair loss is ringworm.
Hormonal imbalances, such as those that occur with thyroid or adrenal glandThe adrenal gland is a glandular organ located above the kidneys in dogs and cats that produces hormones such as epinephrine, norepinephrine, and corticosteroids. These hormones are important for the stress response, metabolism, and electrolyte balance. disorders, can also affect a dog’s coat condition. An underactive thyroid (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., an overproduction of cortisolCortisol is a steroid hormone produced in the adrenal cortex. It plays an important role in the body's stress response, as well as in the metabolism of proteins, lipids, and carbohydrates. Cortisol also helps regulate blood sugar levels and suppress the immune system., are examples of hormonal disorders that can lead to hair loss.

A pet owner can recognize hair loss by looking for bald spots or thinning fur in the affected areas. Increased Scratching, biting, or Licking at these areas can also be an 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..
The veterinarian will perform a thorough examination, including a 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. of the dog, a physical examination, and possibly further diagnostic tests. These may include 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 to determine the exact cause of the hair loss.
In some cases, a skin 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. may be necessary to rule out skin diseases such as autoimmune disease or deeper infections. The veterinarian will also assess the dog’s general health to identify systemic causes such as hormonal imbalances.
Was kann der Tierhalter tun und professionelle Therapieoptionen
The pet owner can take some measures to alleviate hair loss and improve the dog’s condition. This includes brushing the dog regularly to remove loose hair and stimulate the skin. This can also help reduce dandruff and other skin deposits.
It is important to keep the dog’s environment clean to minimize the risk of infections or allergic reactions. This includes regularly cleaning sleeping areas and avoiding potential allergens in the household.
A balanced diet rich in omega-3 and omega-6 fatty acids can support skin health and strengthen the coat. The pet owner should pay attention to high-quality feed and, if necessary, use dietary supplements that promote skin and coat health.
If parasites are suspected, the pet owner should use appropriate antiparasitic agents and regularly check the dog for parasiteA parasite is an organism that lives on or in another living being (the host) and feeds at its expense.
