Can Occur with the Following Diseases:
Grundlagen und mögliche Ursachen
Hair loss in dogs can be caused by a variety of factors, including genetic predispositionA predisposition is an innate inclination or susceptibility of an organism to certain diseases or conditions. In dogs and cats, there may be a genetic predisposition to certain conditions such as hip dysplasia or certain heart diseases., hormonal imbalances, 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., 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, or allergic reactions. Many breeds are more prone to certain types of hair loss due to their genetic predispositionA predisposition is an innate inclination or susceptibility of an organism to certain diseases or conditions.

Hormonal disorders 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 hair loss. These conditions affect the dog’s hormonal balance, which can impair coat growth and maintenance. Another common cause is infestation with parasites such as fleas, mites, or lice, which can cause skin irritation and, as a result, hair loss.
Allergies—whether to food, insect bites, or environmental factors such as pollen and dust—are also common causes of hair loss in dogs. Allergic reactions often cause severe Itching, leading dogs to Scratch or bite to get relief, which worsens the hair loss.
Finally, bacterial or fungal 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 skin, such as dermatitis or ringworm, can also lead to hair loss. These infections cause Inflammatory conditions and irritation that impair coat growth.
Typische Begleitsymptome
-
Itching: Hair loss is often accompanied by severe itching, which causes the dog to scratch or lick excessively, which can worsen the hair loss.
-
Redness or skin rash: In addition to hair loss, there may be redness, skin rashes, or inflammation of the affected skin areas.
-
Scaling: The skin on the affected areas may be dry and form scales, which may indicate an underlying skin condition.
-
Odor: 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 severely inflamed skin can give off an unpleasant smell, which may indicate a bacterial or fungal 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..

Wann zum Tierarzt?
A visit to the vet is urgently needed if the hair loss occurs suddenly and severely, or is accompanied by other symptoms such as open Wounds, severe Itching, lethargy, or increased thirst and urination. These signs could indicate more serious health problems that require immediate treatment.
If the hair loss lasts longer than a few weeks or gets worse, a vet should also be consulted. This also applies if several pets in the household show similar symptoms, as this could indicate a contagiousContagious means infectious. Diseases that can easily be transmitted from one animal to another or from animals to humans are referred to as contagious. condition.
A visit to the vet is also advisable if the hair loss is accompanied by other health changes, such as weight loss, loss of appetite, or behavioral changes, as these symptoms could indicate systemic diseases.
Symptomerkennung für den Tierhalter und tierärztliches diagnostisches Vorgehen
It is important for the pet owner to recognize the hair loss early. Watch for unusual changes in your dog’s coat, such as bald patches or thinning fur, especially in the typical areas around the ears, neck, shoulders, and genital region.
The vet will usually carry out a thorough examination, including checking the skin and coat and, if necessary, further tests. These include skin scrapings to look for parasites, blood tests to identify hormonal imbalances, and possibly skin biopsies to determine infectiousInfectious describes the ability of a pathogen to be transmitted from one individual to another and trigger an infection. It also refers to diseases caused by such pathogens. or allergic causes.
The vet will also take a detailed 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 gather information about the dog’s general health, diet, behavior, and possible Contact with allergens or parasites. This information is crucial for making an accurate 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. of the cause of the hair loss.
Was kann der Tierhalter tun und professionelle Therapieoptionen
As a first measure, the pet owner should prevent the dog from excessive Scratching or Licking. This can be helped by wearing a protective collar or covering the affected areas with a light bandage.
Regular coat care with suitable shampoos and conditioners can help soothe the skin and relieve Itching. However, it is important to choose products that are suitable for dogs and do not contain irritating ingredients.
A balanced diet with high-quality nutrients can also help support skin health and promote coat growth. In some cases, the vet may recommend specific supplements to correct deficiencies.
It is important to keep the dog’s environment clean to prevent reinfectionReinfection refers to the recurrence of an infection in an individual who was previously cured of the same disease. This can be caused by the same or a similar pathogen. or irritation. This includes regularly washing dog beds and vacuuming living areas to reduce parasites and allergens.
If the hair loss is triggered by allergies, it may be necessary to keep the dog away from the triggers. This could mean changing the diet or avoiding Contact with certain plants or environmental factors.
Ausblick auf aktuelle Forschung
Research into hair loss in dogs—especially in the areas of the ears, neck, shoulders, and genital region—is a dynamic field focusing on a wide range of factors. Scientists are investigating the genetic, immunological, and environmental causes of this symptom. A recent study shows that genetic predispositions can play a significant role in certain breeds. For example, breeds such as the Doberman or Boxer are more often affected by inherited hair loss. These studies aim to identify specific genetic markers that could enable prediction and early intervention.
Another area of research focuses on the role of the 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.. In some dogs, an overactive or misdirected immune responseAn immune response is the immune system's reaction to foreign substances (antigens), such as microorganisms or proteins. It involves a series of processes aimed at recognizing, fighting, and eliminating these antigens. leads to Inflammatory conditions and subsequent hair loss. Studies have shown that immunomodulatoryImmunomodulatory describes the ability of a substance to modify the reaction of the immune system. Immunomodulatory drugs can either stimulate the immune system to fight infections more effectively or suppress it to prevent overreactions. therapies that regulate the 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. could deliver promising results in reducing hair loss symptoms. Research is also examining the role of autoimmune diseasesAutoimmune diseases are conditions in which the immune system mistakenly attacks the body's own cells or tissues as if they were foreign substances. Examples in dogs and cats include autoimmune hemolytic anemia and systemic lupus erythematosus. in which the body mistakenly attacks its own hair follicles.
Environmental factors and their impact on hair loss in dogs are also an important research topic. Allergies to certain environmental factors such as pollen, dust, or mites can cause Itching and Scratching in dogs, which in turn causes hair loss. Researchers are developing new methods to diagnose and treat environmental allergies, including the development of hypoallergenic diets and the use of environmental control measures. Research is also looking into the influence of 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 nutrition on coat growth.
The latest techniques in imaging and 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. analysis allow researchers to examine dogs’ skin and hair follicles in greater detail. These technologies help identify differences in skin structure between healthy and affected animals. New 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. and systemic treatments are also being developed to promote hair growth and reduce Inflammatory conditions. Research in this area is focused on improving the effectiveness and safety of these new therapies.
In addition, studies are examining how probiotic supplements and dietary changes affect the skin microbiome and may reduce hair loss. Early studies suggest that a healthy balance of skin microbiota can reduce the risk of Inflammatory conditions 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. that lead to hair loss. This line of research is promising and could offer new, non-invasive treatment options for affected dogs.
