Are you unsure what is wrong with your pet? Feel free to use our symptom checker for more clarity.
The loss of the superficial skin layer, also known as erosion, is a superficial skin defect in dogs in which the uppermost skin layer, the epidermisThe epidermis is the outer layer of skin that protects the body from environmental influences. It consists of several layers of keratinized cells and is responsible for the skin’s barrier function., is lost without affecting deeper tissue.
Can Occur with the Following Diseases:
Basics and possible causes
A dog’s skin consists of several layers, with the epidermisThe epidermis is the outer layer of skin that protects the body from environmental influences. It consists of several layers of keratinized cells and is responsible for the skin's barrier function. forming the outermost layer. This layer provides protectionProtection refers to safeguarding against diseases or harm. In veterinary medicine, this can include protecting animals through vaccinations, the use of parasite control products, or providing a safe environment. against environmental influences and microorganisms. If this layer is damaged, it is called an erosion. An erosion is not as deep as an ulcerAn ulcer is an open wound or erosion of the skin or mucous membrane that often heals poorly and can be caused by a variety of factors, including infections and chronic inflammatory conditions., which affects the dermis, the deeper skin layer.
Erosions can be caused by a variety of factors. One of the most common causes is physical injury, whether from scratching, biting, or rubbing against hard surfaces. Chemical irritations from grooming products or environmental influences can also damage the epidermisThe epidermis is the outer layer of skin that protects the body from environmental influences. It consists of several layers of keratinized cells and is responsible for the skin's barrier function. and cause erosions.
Allergic reactions are another common cause. Dogs can be allergic to certain foods, insect bites, or environmental allergens. These allergies often lead to Itching, which causes the dog to scratch or bite, which in turn damages the skin.
Infections, both bacterial and fungal, can also lead to erosions. If the skin is weakened due to 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., it can be damaged more easily. 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 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. attacks its own skin cells, can also cause erosions in some cases.
Another important factor is 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., which can affect the skin condition and make the skin more susceptible to erosions.
Typical accompanying symptoms
-
Redness: Erosions are often accompanied by a distinct redness of the surrounding skin, indicating inflammation.
-
Itching: Affected dogs often show increased scratching or licking at the affected area, which can further worsen the erosion.
-
Swelling: The affected skin area may appear swollen, indicating an underlying inflammation.
-
Oozing Wounds: Erosions can be moist and oozing, which increases the risk of secondary infectionA secondary infection occurs when an already weakened individual suffers an additional infection, often because the immune system is impaired by the primary infection..
-
Pain: The dog may be sensitive to touch and show pain when the affected skin area is touched.
When to visit the vet?
A visit to the veterinarian is urgently required if the erosions do not heal within a few days or worsen. A veterinarian should also be consulted if the dog shows signs of Pain or the erosion is heavily weeping.
If, in addition to the erosions, further systemic symptoms such as Fever, loss of appetite or lethargy occur, an immediate visit to the veterinarian is necessary. These signs could indicate a more serious underlying disease.
Symptom recognition for animal owners and veterinary diagnostic procedures
It is important for the pet owner to regularly check the affected areas and pay attention to whether the symptoms worsen or new symptoms appear. Regular observation of the dog helps to identify changes early on.
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. and physically examine the dog. The affected skin area is carefully inspected to determine the severity of the erosion. 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 performed to find out the exact cause.
In addition, blood tests can be carried out to rule out or confirm systemic diseases such as hormonal disorders. Depending on the suspicion, 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 or microbiological examinations of the skin samples may also be necessary.
What can pet owners do and professional therapy options
In order to alleviate the dog’s discomfort, the pet owner should ensure that the dog does not scratch or lick the affected areas. Wearing a neck brace can be helpful here to prevent access to the affected area.
The affected skin should be kept clean and dry to minimize the risk of secondary infectionA secondary infection occurs when an already weakened individual suffers an additional infection, often because the immune system is impaired by the primary infection.. Regular cleaning with a mild antiseptic solution can help promote healing.
It is important to use the medications or 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 prescribed by the veterinarian exactly as directed. The pet owner should also ensure that the dog gets enough rest 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. is avoided to support healing.
Outlook on current research
Current research focuses on the molecular mechanisms that lead to skin erosion in dogs. Scientists are particularly investigating the role of proteins and enzymesEnzymes are biological catalysts that accelerate specific chemical reactions in the body without being consumed. They play a crucial role in virtually all physiological processes. involved in the degradation of the skin. The focus is on identifying specific biomarkers that could indicate an impending erosion at an early stage. Advances in genomics and proteomics make it possible to better understand these processes at the cellularCellular refers to cells or consisting of cells. In biology and medicine, it refers to processes, structures, or functions that occur at the level of individual cells. level. The goal is to make more precise diagnoses and develop individually tailored therapies by identifying these biomarkers.
Another area of research deals with the 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. of certain dog breeds for the development of skin erosions. Studies indicate that some breeds are more susceptible to skin problems due to their genetic makeup. In the long term, these studies could lead to the breeding of healthier dogs by identifying and eliminating genetic risk factors.
In addition, the effect of various treatment methods on the healing of skin erosions is being investigated. Researchers are analyzing the effectiveness of 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, such as antimicrobialAn antimicrobial substance is an agent that serves to inhibit the growth of microorganisms such as bacteria, viruses, fungi, and protozoa, or to kill them. Antimicrobials are frequently used to treat infections. creams and ointments, compared to systemic therapies. The development of new drugs that specifically target the molecular mechanisms involved is also a focus. These studies could lead to innovative treatment approaches that accelerate healing and reduce the risk of Infections.
A current topic is the investigation of the microbiome interaction with the skin. Researchers are investigating how the skin microbiome, which consists of a variety of microorganisms, affects the health of the skin. It is believed 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 microbiome can contribute to the development of skin erosions. By specifically modulating the microbiome, new therapeutic approaches could be developed to improve skin health and prevent erosions.
