Von Willebrand Disease
Von Willebrand disease (vWD) is the most common inherited bleeding disorder in dogs, which is highly heterogeneous ranging from an asymptomatic laboratory abnormality to a life threatening bleeding. The condition is caused by a quantitative or qualitative deficiency of von Willebrand factor (vWF), a protein that plays a central role in blood clotting.. Von Willebrand's disease vWD usually comes in two major types, type I and type III. Type III is a severe bleeding disorder with a high risk of spontaneous bleeding as well as a risk of serious bleeding from trauma and surgery. Type 1 is a less severe form.
