Raised skin lesions in dogs refer to abnormalities on the skin surface characterized by a structure that lies above the normal skin level. These can be nodules, bumps, or swelling that can occur either localized or distributed throughout the body.

Can Occur with the Following Diseases:

Basics and possible causes

Dog skin is similar to human skin, consisting of several layers that perform different functions. The epidermis is the outermost layer, which serves as a barrier against environmental influences. Below it lies the dermis, which houses nerves, blood vessels, and hair follicles. Changes in these layers can lead to raised skin lesions.

Raised skin lesions in dogs can be caused by a variety of factors. These include inflammatory processes, infections, allergic reactions, parasitic infestations, or neoplasms, which can be either benign or malignant.

Allergic reactions are often due to food components, insect bites, or environmental allergens. These can lead to wheals or papules that manifest as raised skin lesions.

Infections caused by bacteria, viruses, or fungi can also lead to raised skin lesions. Bacterial infections such as pyoderma or fungal infections such as dermatophytosis often cause nodules or pustules.

Parasitic diseases such as mite infestation (e.g., mange) or flea infestation can also lead to raised skin lesions, which are often accompanied by itching.

Neoplastic changes are another reason for raised skin lesions. Benign tumors such as lipomas are common, but malignant tumors such as mast cell tumors can also occur and should be diagnosed and treated as soon as possible.

Typical accompanying symptoms

  • Itching: Raised skin lesions are often associated with itching, especially when caused by allergic reactions or parasitic infections.

  • Redness: Accompanying the raised changes, the skin may appear reddened, indicating an inflammatory reaction.

  • Hair loss: Hair loss may occur in the area around the raised changes, especially in bacterial or parasitic infections.

  • Crusts: After pustules or blisters break open, crusts may form.

  • Pain sensitivity: Some raised skin lesions can be painful, leading to discomfort in the dog.

  • Behavioral changes: Due to discomfort or pain, behavioral changes such as apathy or irritability may occur.

When to visit the vet?

A visit to the veterinarian is urgently needed if the raised skin lesions grow or spread rapidly, as this could indicate a serious underlying disease. A veterinarian should also be consulted if the skin changes bleed heavily, ooze, or the dog suffers from severe itching that impairs normal behavior.

Another warning sign is when the dog shows signs of systemic diseases, such as fever, loss of appetite, or lethargy, which are associated with the skin changes.

If known risk factors such as previous tumors or a genetic predisposition to skin diseases exist, an early veterinary examination is advisable.

Symptom recognition for animal owners and veterinary diagnostic procedures

The pet owner should regularly inspect the raised skin lesions and pay attention to changes in size, color, or shape. Taking photos of the affected areas can be helpful to show the veterinarian the course of the changes.

The veterinarian will first take a thorough anamnesis and examine the dog clinically. The skin is carefully inspected and, if necessary, a skin scraping or biopsy is taken to determine the cause of the changes more precisely.

Further diagnostic measures may include blood tests, allergy tests, or imaging procedures such as X-rays or ultrasound to rule out or confirm systemic causes.

What can pet owners do and professional therapy options

The pet owner can help alleviate the symptoms by keeping the dog away from potential allergens and ensuring a clean, parasite-free environment. Regular bathing with a veterinarian-recommended shampoo can help soothe the skin.

It is important that the dog is prevented from scratching or licking the affected areas to avoid worsening the changes or secondary infections. A protective collar can be helpful.

Until the veterinary examination, no independent treatments such as ointments or medications should be used without consulting the veterinarian, as this could complicate the diagnosis or worsen the skin changes.

Outlook on current research

In current research on raised skin lesions in dogs, scientists are focusing on identifying and classifying the underlying mechanisms that can lead to these skin changes. Modern molecular and genetic techniques are being used to investigate the role of genes and environmental factors in the development of skin diseases. Much of the research is supported by the development of new diagnostic methods designed to help analyze and better understand skin changes more accurately.

Another focus of research is on improving therapy options. Researchers are working to develop specific drugs and treatments that target the molecular causes of skin changes. The use of biologics and immunotherapies is also being investigated to specifically target inflammatory and autoimmune processes that can lead to skin changes. The exploration of natural remedies and alternative therapies is also being advanced to provide gentler treatment options.

Innovative imaging techniques are being developed to diagnose skin changes in dogs earlier and more accurately. This includes the use of high-frequency ultrasound, digital dermatoscopy, and other advanced technologies that allow a detailed analysis of the skin structure. These technologies help veterinarians to detect raised skin lesions early and, if necessary, intervene therapeutically in good time.

Another area of research deals with the role of the skin microbiome in the development of raised skin lesions. Scientists are investigating how the balance of the skin flora can be influenced to strengthen the skin’s immune system and reduce the occurrence of skin diseases. This research could lead to new approaches in the prevention and treatment of skin changes by specifically modulating the microbiome.

In summary, research on raised skin lesions in dogs aims to improve both diagnostic procedures and the development of new and more effective treatment methods. Advances in genetics, molecular biology, and imaging are expected to lead to better care and understanding of these common diseases.

Frequently asked questions

  1. What are raised skin lesions in dogs? Raised skin lesions in dogs are areas of skin that rise above the normal skin surface. These can have various shapes and sizes and vary in texture. They can appear as nodules, papules, plaques, or blisters.

  2. Can raised skin lesions in dogs disappear on their own? Some raised skin lesions may disappear on their own, especially if they are due to a temporary irritation or allergic reaction. However, in many cases, veterinary treatment is necessary to identify and treat the cause.

  3. Are raised skin lesions in dogs always a cause for concern? Not all raised skin lesions are serious or worrying. Some can be harmless, such as harmless cysts or warts. Nevertheless, it is important to have any change examined by a veterinarian to obtain an accurate diagnosis.

  4. How are raised skin lesions in dogs diagnosed? The diagnosis of raised skin lesions in dogs usually begins with a thorough clinical examination by a veterinarian. Additional diagnostic tests such as skin biopsies, cytological examinations, or blood tests may be necessary to determine the exact cause.

  5. Can raised skin lesions in dogs be painful? Yes, raised skin lesions in dogs can be painful, especially if they are inflamed or infected. This can lead to discomfort or itching, which is why it is important to have these changes checked by a veterinarian.

  6. What treatment options are available for raised skin lesions in dogs? Treatment depends on the underlying cause of the skin changes. Options range from topical treatments and antibiotics to surgical procedures or special medications, depending on the diagnosis and severity.
