Dystrophic Epidermolysis Bullosa

skin & connective tissue

This condition arises from a mutation in Collagen Type VII. Collagens of all types anchor the layers of our skin together: they are what gives skin its springy, youthful texture (and thus are a big component of anti-wrinkle creams). Collagen Type VII has the specific job of connecting the epidermis, the surface layer of the skin, to the underlying tissues, leading to dogs with especially stretchy skin that is easily detached from the underlying tissues.

  • Signs and symptoms

    Affected dogs have skin that is injured easily and stretches more than normal.

    Signs first appear in puppies.

  • Diagnosis

    Genetic testing, skin biopsy, and clinical signs can be used to diagnose this condition.

    A variety of therapies, including skin grafts, stem cell therapy, and gene therapy, are under investigation for the treatment and prevention of EB, but these are young in development.

  • What to do if your dog is at risk

    Actions

    • Trying to prevent injuries from occurring is ideal. Seek treatment immediately if your affected dog is wounded.
