Estimated prevalence of canine Type 2 Von Willebrand disease in the Deutsch-Drahthaar (German Wirehaired Pointer) in Europe.

Type 2 Von Willebrand disease (VWD) is a severe coagulopathy occurring in the Deutsch-Drahthaar dog (or German Wirehaired Pointer, DD/GWP). Recently, a causative recessive mutation has been identified, and a DNA test is now available for individual screening. The genotype distribution (clear, carrier, and affected dogs) was investigated in 1855 DD/GWP dogs using data collected by the DD DNA-VWD-Databank in several European countries.
