Von Willebrand disease (vWD)

Von Willebrand disease (VWD) is a genetic disorder caused by missing or defective von Willebrand factor (VWF), a clotting protein.

 

Symptoms include spontaneous bleeding from the nose, gum and other mucous membranes.

 

Excessive bleeding occurs after an injury, trauma or a surgery. Often dogs don’t show clinical signs until something starts the bleeding, such as nail trimming, teething, spaying, sterilising, tail docking, cropping or other causes. Bleeding also occurs internally in the stomach, intestines, urinary tracts, the genitals and / or into the joints.
