Darier Disease

skin & connective tissue

Darier Disease is a skin condition that causes crusted areas, cyst formation, and other abnormalities.

  • Signs and symptoms

    Affected dogs may have well-defined areas of crusting or ulceration within their ears and/or cysts (nodules) anywhere on their skin. These lesions can be both painful and itchy.

    This disease is typically diagnosed in puppies, often before the age of six months.
