Von Willebrand Disease I
Von Willebrand disease type 1 (vWD1) is an inherited bleeding disorder caused by little to no normal blood clotting proteins in the body. There are three variations of vWD, with type 1 being the most common and carrying a mild-to-moderate bleeding risk. Some breeds susceptible to this disorder include Bernese Mountain Dogs, Welsh Corgis, Doberman Pinschers, Poodles, and Manchester Terriers.
