Skin lesions on the paws in dogs are visible changes in the skin’s structure or color that occur on the paws. They can take various forms, such as redness, swelling, ulcers, or blisters, and may indicate a variety of underlying problems.

Can Occur with the Following Diseases:

Pododermatitis (Inflammatory Conditions on the Paws)

Basics and possible causes

Skin lesions on the paws of dogs can be caused by numerous factors, including physical, chemical, and biological influences. Physical causes include injuries from sharp objects, such as shards of glass or thorns, which can penetrate the skin and cause lesions. Extreme temperatures, such as hot asphalt in the summer or road salt in the winter, can also irritate and damage the sensitive skin on the paws.

Chemical causes include contact with irritating substances. These include, for example, cleaning agents, fertilizers, or certain types of plants that can 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. chemical reactions on the skin. Biological causes include infections caused by bacteriaBacteria are microscopic, single-celled organisms that exist in almost every environment on Earth. Some types of bacteria are beneficial or even essential to life, while others can cause disease., fungi, or parasites. Such infections can occur primarily or secondarily if the skin is already weakened by another cause.

Allergies are another common cause of skin lesions on the paws. Dogs can be allergic to various environmental factors, including pollen, house dust mites, or certain food ingredients. These allergic reactions can 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. severe itching and associated scratching or biting of the paws, which can lead to lesions.

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 dog’s 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. mistakenly attacks the body’s own tissue, can also cause skin lesions on the paws. An example of this is the pemphigus complex, which causes blistering and erosions on the skin and mucous membranes. In addition, hormonal disorders, such as hypothyroidism, can affect skin health and lead to lesions.

Typical accompanying symptoms

Redness: One of the most common accompanying symptoms of skin lesions is redness of the affected area. This redness indicates an inflammatory condition that can be caused by the above-mentioned causes.
Swelling: In addition to redness, the paws may also appear swollen. Swelling is often a sign that fluid has accumulated in the tissue, often in response to an injury or 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..
Itching: Many dogs with skin lesions on the paws show signs of itching. They often lick, bite, or scratch the affected areas, which can further worsen the lesions.
Blistering: In some cases, blisters can form on the skin. These blisters can be filled with fluid and burst, leading to open wounds.
Pain: Skin lesions can be painful, especially if they are infected or in an advanced stage. Dogs may show lameness or spare the affected paw.
Changes in behavior: Dogs with painful or itching paw lesions may show changes in behavior, such as irritability or withdrawal.

When to visit the vet?

A visit to the veterinarian should be considered if the skin lesions do not subside within a few days or if they worsen. A veterinary examination is advisable, especially if the dog shows signs of pain, excessive licking, or biting. A veterinarian should also be consulted if fever, loss of appetite, or lethargy occur, as these may be signs of a systemic 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..

If the lesions are accompanied by severe itching that prevents the dog from resting, or if signs of an allergic reaction, such as swollen eyes or respiratoryRespiratory refers to breathing or the process of breathing. Respiratory diseases affect the respiratory tract and can impair the ability to breathe effectively. distress, occur, immediate veterinary intervention is required.

Symptom recognition for animal owners and veterinary diagnostic procedures

For the pet owner, the first step in symptom recognition is to regularly inspect the dog’s paws. Attention should be paid to signs of redness, swelling, blisters, or open wounds. Also, if the dog licks or bites its paws excessively, this is 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. of a possible problem.

In the veterinary diagnostic procedure, the examination usually begins with a thorough anamnesis and a physical examination. The veterinarian will examine the dog for signs of pain, swelling, redness, or other abnormalities. Depending on the suspicion, further diagnostic tests may be necessary, such as skin swabs, biopsies, or blood tests, to diagnose infections, allergies, or 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 some cases, an allergy testAn allergy test is a method for the diagnosis of allergic reactions. The body is exposed to various allergens to identify which substances trigger an allergic reaction. can also be performed to identify specific allergens that cause the skin lesions. If a hormonal disorder is suspected, blood tests can be ordered to check hormoneHormones are chemical messengers produced by endocrine glands and released into the bloodstream to affect specific cells or organs in the body. They regulate numerous bodily functions, including growth, metabolism, and reproduction. levels.

What can pet owners do and professional therapy options

The pet owner can take immediate measures to alleviate the dog’s discomfort and prevent further damage. One of the first measures is to clean the affected paws with clear, lukewarm water to remove dirt, irritants, or allergens. It is important to dry the paws thoroughly afterwards to prevent the growth of bacteriaBacteria are microscopic, single-celled organisms that exist in almost every environment on Earth. Some types of bacteria are beneficial or even essential to life, while others can cause disease. or fungi.

Applying a protective bandage can help protect the paws and prevent the dog from licking or biting the lesions. In mild cases, over-the-counter ointments or creams can help relieve itching and inflammatory conditions, but this should be done in consultation with the veterinarian.

It is also important to prevent the dog from licking or biting the affected paws. A neck collar (also known as an “Elizabethan collar”) can help prevent access to the paws.

In the long term, the pet owner should check the dog’s environment for possible triggers for skin problems. This includes avoiding known allergens, using pet-friendly cleaning agents, and avoiding walks on hot asphalt or gritted paths.

The diet should also be checked, as a balanced diet contributes to maintaining skin health. Supplements such as omega-3 fatty acids can have an anti-inflammatory effect and strengthen the skin barrier. Close cooperation with the veterinarian is crucial to determine the best course of action for the individual dog.

Outlook on current research

Current research is intensively investigating how genetic factors contribute to the susceptibility of dogs to skin lesions on the paws. Studies show that certain breeds are genetically predisposed to developing these symptoms. Researchers are focusing on identifying specific genes that are related to the integrity of the skin barrier and the dog’s 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.. These findings could help to develop targeted breeding programs in the future to reduce the risk of these symptoms.

Another focus of research is on exploring the microbiome composition on the paws of dogs. Scientists are analyzing how an imbalanceImbalance refers to an imbalance or disruption of normal function or composition in the body, which can lead to health problems. in the microbial flora could affect skin lesions. Initial results suggest that certain types of bacteriaBacteria are microscopic, single-celled organisms that exist in almost every environment on Earth. Some types of bacteria are beneficial or even essential to life, while others can cause disease. could offer a protective function against pathogenic microorganisms. The manipulation of the microbiome could therefore be a promising approach for the preventionPrevention includes measures taken to prevent diseases or injuries. In veterinary medicine, this includes vaccinations, parasite control, and health monitoring. and treatment of skin lesions.

There are also advances in the development of 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. therapyTherapy refers to the treatment of diseases or disorders with the aim of alleviating symptoms, promoting healing, or improving quality of life. Therapies can be medicinal, surgical, or through other medical interventions. approaches. Researchers are testing innovative ointments and creams that have anti-inflammatory and healing properties. These products are often based on natural ingredients such as plant extracts or biotechnologically produced molecules that promote skin regeneration. Clinical trials are underway to evaluate the effectiveness and safety of these new treatments.

Another interesting development is the application of technologies for the early detection of skin lesions. New imaging techniques and wearable sensors are being developed to monitor subtle changes in the skin. These technologies could enable veterinarians and dog owners to detect and treat skin problems early before they worsen.

In addition, behavioral research is examining the effects 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 environmental factors on the development of skin lesions. It is believed that 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. hormones impair immune function, making the skin more susceptible to inflammatory conditions. Behavioral interventions and stress-reducing measures could therefore become part of integrative therapyTherapy refers to the treatment of diseases or disorders with the aim of alleviating symptoms, promoting healing, or improving quality of life.

Finally, the role of nutrition in the preventionPrevention includes measures taken to prevent diseases or injuries. In veterinary medicine, this includes vaccinations, parasite control, and health monitoring. and treatment of skin lesions on the paws is also being explored. Some studies suggest that a balanced diet rich in essential fatty acids and antioxidants can promote skin health. Special diets are being developed to strengthen the skin barrier and reduce inflammatory processes.
