Von Willebrand disease type II (VWDII) is an inherited bleeding disorder affecting Deutsch Kurzhaars. Dogs affected with VWDII have decreased levels and abnormal function of von Willebrand coagulation factor (vWf), which is an essential protein needed for normal blood clotting. Affected dogs generally have moderate to severe signs of a bleeding disorder. Affected dogs may bruise easily, have frequent nosebleeds, bleed from the mouth when juvenile teeth are lost and experience prolonged bleeding after surgery or trauma. The bleeding may be severe enough to cause death. Due to variable severity of the disorder, affected dogs may not be identified until a surgery is performed or trauma occurs at which time excessive bleeding is noted. Veterinarians performing surgery on known affected dogs should have ready access to blood banked for transfusions. Dogs can have a normal lifespan with this condition although they are susceptible to life-threatening bleeding with an accidental injury or any surgical procedure.
