Von Willebrand disease (VWD) is almost always inherited. Inherited means that the disorder is passed from parents to children though genes. You can inherit type 1 or type 2 VWD if only one of your parents passes the gene on to you. You usually inherit type 3 VWD only if both of your parents pass the gene on to you.
Von Willebrand's Disease (vWD). Von Willebrand's disease has been identified in a wide range of canine breeds, and is the most common of the inherited bleeding disorders.As with humans, there are three classifications of this disease, Types I, II, and III.ype III vWD is found in animals that have essentially no plasma vWF. The disease has been reported in many breeds of dog, and is generally diagnosed by an ELISA test for plasma vWF following a bleeding event. Five mutations have been identified that cause vWD in canines.
