Prekallikrein Deficiency

Blood

Prekallikrein is an enzyme necessary for the activation of certain clotting proteins. Fortunately, this is a benign blood disorder and is not associated with increased bleeding tendencies.

  • Signs and symptoms

    Affected dogs have abnormally long clotting times on laboratory coagulation tests, but this does not lead to an increased bleeding risk clinically.

    Dogs are born with this disorder, but it is often not recognized unless your veterinarian performs certain blood tests.
