Hyperkeratosis is a common condition that affects dog paws, causing thickened and excessive growth of the outer layer of the skin. It is often referred to as "hairy paw" or "hairy dog feet" due to the appearance it gives to the affected areas. Here, we will explore the causes, symptoms, and treatment options for hyperkeratosis in dog paws.

Hyperkeratosis in Dog Paws

Understanding Hyperkeratosis

Hyperkeratosis is a dermatological condition that commonly affects the paws of dogs. It is characterized by the excessive growth and thickening of the outer layer of the skin, known as the keratin layer. This condition can lead to various symptoms and discomfort for our canine companions.

Types of Hyperkeratosis

Two main types of hyperkeratosis can occur in dog paws:

1.      Nasal Hyperkeratosis: This type affects the nose of the dog. It leads to the thickening and hardening of the skin on the nasal planum, resulting in a rough, dry, and crusty appearance.

2.      Paw Pad Hyperkeratosis: This type specifically affects the paw pads of dogs. It causes the excessive growth of keratin on the pads, leading to a rough and thickened texture. The paw pads may become dry, cracked, and painful.

Primary and Secondary Hyperkeratosis Stages

Hyperkeratosis can be classified into two stages: primary and secondary hyperkeratosis. Understanding the differences between these types is essential for accurate diagnosis and appropriate treatment. Let's explore primary and secondary hyperkeratosis in more detail:

Primary Hyperkeratosis

Primary hyperkeratosis refers to cases where the condition occurs idiopathically, meaning there is no underlying cause or identifiable trigger. It is a self-standing condition that develops without any other concurrent health issues. The exact cause of primary hyperkeratosis is unknown, but it is believed to have a genetic component.

In primary hyperkeratosis, the excessive thickening of the skin occurs primarily on the paw pads, nose, or other affected areas. This condition can be seen in specific dog breeds, such as Black Labradors, Golden Retrievers, French Bulldogs, Irish Terriers, and West Highland White Terriers. These breeds have a higher predisposition to primary hyperkeratosis, although it can still occur in dogs of other breeds as well.

Secondary Hyperkeratosis

Secondary hyperkeratosis, on the other hand, develops as a result of an underlying health issue or external factors. It is often associated with various contributing factors, including:

1.      Allergies: Dogs with allergies, whether to food, environmental factors (such as pollen or dust mites), or contact irritants, may develop secondary hyperkeratosis as a response to the allergens.

2.      Autoimmune Disorders: Some autoimmune conditions can disrupt the normal functioning of the immune system, leading to abnormal skin cell growth and thickening. Secondary hyperkeratosis can occur in dogs with autoimmune disorders.

3.      Infections: Chronic infections, particularly those affecting the skin, can trigger secondary hyperkeratosis. Bacterial, fungal, or yeast infections can contribute to the thickening of the affected areas.

4.      Nutritional Deficiencies: Inadequate nutrition, particularly deficiencies in essential vitamins, minerals, or fatty acids, can contribute to the development of secondary hyperkeratosis. Proper nutrition is crucial for maintaining healthy skin and preventing skin-related conditions.

5.      Endocrine Disorders: Hormonal imbalances, such as hypothyroidism or Cushing's disease, can impact the health of the skin and contribute to secondary hyperkeratosis.

6.      Environmental Factors: Exposure to harsh environmental conditions, including extreme temperatures, abrasive surfaces, or chemicals, can cause irritation and thickening of the skin, leading to secondary hyperkeratosis.

Identifying the underlying cause of secondary hyperkeratosis is vital for effective treatment. A veterinarian will conduct a thorough examination, consider the dog's medical history, and may recommend additional tests to determine the specific cause and develop an appropriate treatment plan.

Causes of Hyperkeratosis in Dog Paws

Hyperkeratosis in dog paws can have various causes, including genetics, environmental factors, and underlying health conditions.

Hyperkeratosis in Dog


Some dog breeds are more prone to developing hyperkeratosis than others. Breeds such as Labrador Retrievers, Irish Setters, and Bull Terriers have a higher predisposition to this condition. Genetic factors can affect the quality of keratin production in the paws, leading to abnormal growth.

Environmental Factors

Exposure to harsh weather conditions, such as extreme heat or cold, can contribute to the development of hyperkeratosis. Walking on rough surfaces, like concrete or asphalt, can also cause friction and damage to the paw pads, triggering the condition.

Health Conditions

Certain health conditions, such as allergies, autoimmune disorders, or hormonal imbalances, can lead to the development of hyperkeratosis in dog paws. These conditions affect the overall health of the skin and may disrupt the normal keratin production process.

Symptoms of Hyperkeratosis

Identifying the symptoms of hyperkeratosis is crucial for early detection and prompt treatment. Common signs of hyperkeratosis in dog paws include:

Excessive Paw Pad Growth

One of the most noticeable symptoms is the thickening and excessive growth of the paw pads. The affected areas may appear rough, and scaly, and have a yellowish or grayish color.

Cracked and Dry Pads

Hyperkeratosis can cause the paw pads to become dry, cracked, and prone to bleeding. These cracks can be painful for the happy dog and may increase the risk of secondary infections.

Discomfort and Limping

Dogs with hyperkeratosis often experience discomfort and pain when walking. They may limp or favor one paw over the others due to the discomfort caused by the thickened skin.

It is critical to monitor your dog's paw pads regularly and consult with a veterinarian if you notice any of these symptoms. Early intervention and proper treatment can help manage hyperkeratosis and improve your dog's paw health.

Diagnosis of Hyperkeratosis

Diagnosing hyperkeratosis in dog paws requires a thorough veterinary examination. The veterinarian will conduct various assessments to determine the presence of hyperkeratosis and rule out other possible conditions. During the diagnosis process, the following steps may be taken:


Veterinary Examination

The veterinarian will visually inspect the dog's paw pads to check for any signs of hyperkeratosis. They will carefully examine the texture, thickness, and color of the paw pads. Additionally, they may evaluate the overall condition of the dog's skin.

Skin Biopsy

In some cases, the veterinarian may perform a skin biopsy to confirm the diagnosis. A small sample of the affected skin will be collected and sent to a laboratory for analysis. The biopsy results can help determine if hyperkeratosis is the underlying cause of the symptoms.

It is required to consult with a veterinarian if you suspect your dog has hyperkeratosis. They have the expertise to provide an accurate diagnosis and recommend appropriate treatment options based on the specific needs of your furry friend.

Treatment Options

Although hyperkeratosis cannot be completely cured, there are several treatment options available to manage the condition and alleviate the associated symptoms.

Topical Creams and Balms

The application of specialized topical creams and balms can help soften the thickened skin and reduce dryness. These products often contain moisturizing ingredients, such as shea butter or coconut oil, to nourish the paw pads.

Regular Moisturizing

Regular moisturizing is essential to prevent excessive dryness and cracking of the paw pads. Pet-safe moisturizers should be applied to the affected areas daily to keep the skin hydrated.

Paw Pad Trimming

Trimming the excess growth of the paw pads can help manage hyperkeratosis. It is necessary to do this carefully to avoid causing any injuries to the dog's paws. Professional groomers or veterinarians can assist with this procedure.

Nutritional Supplements

Supplementing the dog's diet with essential fatty acids, such as omega-3 and omega-6, can promote healthy skin and reduce inflammation associated with hyperkeratosis. Consultation with a veterinarian is recommended to determine the appropriate dosage.

Protective Footwear

Using protective footwear, such as booties or paw wax, can provide an additional layer of protection for the paw pads. These products shield the paws from harsh surfaces and prevent further damage.

Preventing Hyperkeratosis

Taking preventive measures can help reduce the risk of hyperkeratosis in dog paws. Here are some tips to keep your dog's paw pads healthy:

Regular Paw Care

Maintain a regular paw care routine by cleaning the paws after outdoor activities and inspecting them for any signs of damage or infection. Trimming the nails and removing excess hair around the paw pads can also prevent debris accumulation.

Proper Nutrition

A balanced and nutritious diet is essential for maintaining healthy skin and preventing various skin conditions. Ensure that your dog's diet includes high-quality proteins, vitamins, and minerals to support optimal skin health.

Environmental Protection

Protect your dog's paws from extreme weather conditions. In hot weather, avoid walking on scorching pavement, and in cold weather, use dog booties to shield the paws from ice and salt.
