Hyperkeratosis in Pets

One condition that can be challenging is hyperkeratosis in pets. Hyperkeratosis is an abnormal thickening of the skin, commonly affecting the paws and nose of both dogs and cats. Although it might seem like a superficial skin problem, it can cause discomfort and even infections if left untreated.

 

Hyperkeratosis in dogs and cats is typically characterized by thickened, rough, and cracked skin. The most affected areas are the paws and the nose. 

Symptoms

The pet’s paws or nose feel more calloused, and the skin may appear dry and thick. The skin can crack, with fissures, dryness, flakiness, and/or peeling. This can be a very painful condition for your pet, especially if it affects the paws. In this case, your pet might avoid putting pressure on their feet, and you may observe them limping.

Causes

Environmental factors may also play a role. For example, exposure to extreme temperatures (such as hot pavement) can exacerbate or trigger the development of hyperkeratosis. Interestingly, some underlying health conditions can also cause hyperkeratosis. For instance, hormonal imbalances, allergies, or even autoimmune diseases. However, it can also be a part of the skin changes that occur with age.

Diagnosis

During a veterinary examination, your vet may proceed with skin scrapings or a biopsy to rule out cancer and other conditions. A blood test may also be important to check for hormonal changes and autoimmune conditions.

Treatment

Topical Treatments: These are often the most common form of treatment for hyperkeratosis in dogs and cats. Your vet may recommend creams or ointments that help moisturize and soften the affected areas.

Protective Booties or Paw Balms: You can also use protective booties or paw balms to prevent irritation while walking with your pet.

Medications: These are prescribed only if there is an underlying infection or an autoimmune disease causing the issue.

Surgery: In severe cases, surgery may be an option, especially if the condition is causing significant pain or infection.
