Hyperkeratosis is a skin condition in dogs that results from the overproduction of keratin, a protein that makes up the skin, hair, and nails. While hyperkeratosis does not usually affect a dog's nails, it can cause thickened, discoloured, and brittle nails that grow more rapidly than usual. This condition commonly affects a dog's paw pads and nose, leading to thickened and hardened skin that may crack and cause discomfort. Although hyperkeratosis is rarely a medical emergency, severe cases can lead to pain and secondary infections.

How to identify hyperkeratosis in dogs
Hyperkeratosis is a skin condition in dogs that occurs due to the overproduction of keratin, a type of protein that makes up the skin, hair, and nails in a dog's body. While it is rarely a medical emergency, it can cause discomfort and pain when walking if left untreated.
Signs and Symptoms
The most obvious symptom of hyperkeratosis in dogs is the presence of thickened, dry, rough, and hard skin on their paw pads, nose, and elbows. This skin overgrowth may also extend to other areas such as the edge of the ears, skin of the stomach, friction areas, and calluses. The skin may crack, fissure, or erode, leading to bleeding and pain. In some cases, the thickening may be quite dramatic and noticeable.
Diagnosis
Hyperkeratosis in dogs is typically diagnosed by a veterinarian through a physical examination. The distinct appearance and pattern of the affected skin make it easier for vets to identify the condition. During the examination, the vet may take a sample of the affected skin for closer examination and run blood work to check for any underlying infections.
Treatment
While there is no known cure for hyperkeratosis, the condition can be managed through various treatments to keep your dog comfortable and pain-free. Treatment options include:
- Using ointments or balms to soften the dry, hard tissue.
- Trimming the nails and affected areas regularly.
- Soaking the affected paws in warm water with Epsom salt to relieve pain.
- Applying petroleum jelly to the affected areas.
- Removing excess tissue in severe cases.
- Antibiotics or antifungal treatments for secondary skin infections.
It is important to note that hyperkeratosis can be passed down genetically or occur due to age-related changes, trauma, infectious diseases, or immune-mediated diseases. Certain breeds, such as brachycephalic breeds with short muzzles, are more predisposed to the condition.

Treatment and management of hyperkeratosis
Hyperkeratosis in dogs is a skin condition that occurs due to the overproduction of keratin, a type of protein that makes up the skin, hair, and nails in a dog's body. While the condition is usually genetic, it can also be caused by repeated pressure on thin skin, typically in older dogs. Although hyperkeratosis is not life-threatening, severe cases can cause pain and discomfort, and lead to secondary skin infections.
Since hyperkeratosis has no known cure, treatment focuses on managing symptoms and improving the dog's quality of life. Here are some ways to treat and manage the condition:
Consult a veterinarian: While some sources suggest home remedies, it is important to consult a veterinarian for a proper diagnosis and treatment plan. The veterinarian will conduct a thorough physical examination and may recommend diagnostic tests such as blood work, skin biopsy, and culture and sensitivity testing to identify any underlying health issues or infections.
Trimming and grooming: Trimming the excess keratin and grooming your dog's nails regularly can help prevent infection, reduce discomfort, and improve mobility. It is important to consult a veterinarian or experienced groomer before attempting any trimming yourself, as improper techniques can cause pain or injury.
Topical treatments: Your veterinarian may recommend topical treatments such as ointments or creams designed specifically for dog skin conditions. These products often contain ingredients like salicylic acid, urea, petrolatum, or propylene glycol, which help break down excess keratin and provide soothing relief from itching and inflammation.
Soothing baths: Soaking your dog's affected paws in warm water with mineral salts like Epsom salt can help relieve pain and discomfort. It is recommended to soak for 5-15 minutes multiple times a day, followed by applying a keratolytic agent to help moisture bind to the skin.
Nutritional support: Providing nutritional support by ensuring your dog eats a healthy diet that supports skin health is crucial. A good diet includes fatty acids, vitamins, and minerals, and adequate hydration.
Lifestyle changes: Making lifestyle changes, such as avoiding walking your dog on hot pavements or roads covered with road salt, can help protect your dog's paws from potential irritants and infections. Additionally, providing deep bedding for dogs with hyperkeratosis on their elbows can help ease pressure on affected areas.
Treat underlying conditions: In some cases, hyperkeratosis may be a sign of an underlying autoimmune, hormonal, viral, or nutritional disease. Treating any underlying medical conditions is an important aspect of managing hyperkeratosis.

The role of keratin in dogs' nails, skin, and hair
Hyperkeratosis is a skin condition in dogs that occurs due to an overproduction of keratin, a type of protein that constitutes the skin, hair, and nails in dogs. While keratin is essential for the development of fur, skin, and nails in dogs, its overproduction can lead to thickened, dry, and callused skin on their feet, nose, or elbows. This condition is characterised by hardened skin, which may crack and cause discomfort or pain. In some cases, hyperkeratosis may also appear as furry protrusions on the pads of the dog's feet.
Keratin is a crucial component of a dog's nails, providing strength and structure. In healthy amounts, it helps protect the nails from damage and wear and tear. However, in the case of hyperkeratosis, the overproduction of keratin can lead to nail overgrowth and thickening. This nail overgrowth is a result of the body's attempt to protect the nails from further damage. While trimming the nails regularly can help manage nail length, it is important to be careful not to cut too close to the quick, which can be painful for the dog.
Keratin also plays a vital role in a dog's skin health. It acts as a protective layer, shielding the skin from external factors and potential irritants. A healthy amount of keratin helps maintain the skin's integrity and protects against infections. However, in hyperkeratosis, the excess keratin can cause the skin to become harder and thicker, leading to discomfort and pain, especially when walking or standing. The thickened skin may crack, providing an entry point for bacteria and other harmful particles, increasing the risk of skin infections.
Additionally, keratin is essential for a dog's hair growth and development. It provides structure and strength to the hair strands. While a healthy amount of keratin promotes a shiny and healthy coat, an overproduction of keratin in hyperkeratosis can lead to excess hair growth, particularly on the paws and between the paw pads. Regular grooming and trimming of the excess hair in this area are important to prevent the buildup of hair and potential irritation.
While hyperkeratosis itself is not life-threatening, severe cases can cause significant discomfort and pain. Treatment options focus on managing symptoms and preventing complications. This includes applying moisturising balms or topical ointments to soften the keratin growth and relieve pain. Keeping the dog's bed well-cushioned can also help reduce pressure on areas prone to excess keratin, such as the elbows.

The causes of hyperkeratosis in dogs
Hyperkeratosis in dogs is a skin condition that occurs due to the excessive production of keratin, a type of protein that makes up the skin, hair, and nails in a dog's body. While the condition is rarely a medical emergency, it can cause discomfort and pain when walking if the hardened skin cracks or gets infected.
Genetics and Age
Canine hyperkeratosis is usually a genetic condition, often inherited from the parents. It is more common in certain breeds, such as griffon breeds, cocker spaniels, boxers, Boston terriers, beagles, Labrador retrievers, and basset hounds. Age is also a factor, as senior dogs are more prone to developing excess calluses due to repeat pressure on thin skin.
Underlying Medical Conditions
In some cases, hyperkeratosis can be a symptom of an underlying medical issue. Several autoimmune, hormonal, viral, and nutritional diseases can lead to hardening and thickening of the skin on a dog's paw pads. For example, pemphigus foliaceus, lupus erythematosus, Cushing's disease, canine distemper virus, and zinc deficiency have been associated with hyperkeratosis.
Trauma and Infectious Diseases
Trauma, infectious diseases, and immune-mediated diseases can also contribute to the development of hyperkeratosis. For instance, chronic liver disease or a pancreatic tumour (hepatocutaneous syndrome) can lead to hyperkeratosis lesions on the nose and paw pads.
Environmental Factors
Environmental factors, such as walking on hot pavement or roads treated with road salt, can damage a dog's paws and potentially trigger hyperkeratosis. Proper grooming, including trimming the nails and hair between the paw pads, can help prevent the condition. Additionally, a healthy diet rich in fatty acids, vitamins, and minerals can support skin health and reduce the risk of hyperkeratosis.

How to prevent hyperkeratosis in dogs
Hyperkeratosis in dogs is a skin condition that occurs when there is an excess production of keratin, a type of protein that makes up the skin, hair, and nails in a dog's body. While it is rarely a medical emergency, it can cause discomfort and pain when walking if left untreated. Therefore, it is important to know how to prevent it.
Firstly, it is important to understand the causes of hyperkeratosis in dogs. While it is usually a genetic condition, it can also be caused by repeat pressure over thin skin, typically in older dogs. Certain breeds are at a higher risk, including Dogue de Bordeaux, Irish Terriers, Labrador Retrievers, Golden Retrievers, and Greyhounds. Additionally, brachycephalic breeds with short muzzles and smooshed-like faces commonly experience hyperkeratosis on their noses and paws due to physical characteristics that lead to a buildup of keratin.
To prevent hyperkeratosis in dogs, it is recommended to:
- Monitor the condition of your dog's paw pads regularly. Check for any cracks, roughness, or thickened, dry calluses on the surface.
- Keep your dog's nails trimmed to avoid accidents or scraping.
- Provide your dog with a well-cushioned bed, especially if their elbows are affected by hyperkeratosis, to ease pressure on their thin skin.
- Ensure your dog is eating a healthy diet that supports skin health, including fatty acids, vitamins, and minerals.
- Keep your dog hydrated by providing access to fresh water at all times.
- Avoid walking your dog on hot pavement or roads covered with road salt, as these surfaces can damage their paws and lead to infections.
- When grooming your dog, trim the excess hair between the paw pads and nails to prevent buildup.
- If your dog has thickened, hard skin on their paws, consider soaking their feet in warm water with Epsom salt to relieve pain.
- Apply petroleum jelly or moisturizing balm to their paw pads, nose, and elbows to keep their skin soft and free of cracks.
- Consult your veterinarian for annual check-ups and to rule out any underlying conditions that could be causing hyperkeratosis.
While there is no known cure for hyperkeratosis in dogs, early diagnosis and treatment can help your dog lead a healthy and comfortable life.
