title: An inherited platelet function defect in Basset hounds.
abstract: An inherited platelet function defect occurring in a family of basset hounds has been described. The trait is transmitted as an autosomal characteristic and appears to be expressed clinically only in the homozygous state. The characteristics of this platelet defect include:1) marked bleeding tendencies and prolonged skin bleeding times in either male or female dogs.2) normal blood coagulation mechanism.3) adequate numbers of circulating platelets which appear morphologically normal by light microscopy.4) normal whole blood clot retraction.5) deficient in vivo platelet consumption and in vitro platelet retention in glass bead columns.6) defective ADP-induced platelet aggregation in homozygotes, apparently normal ADP response in heterozygotes, and defective collagen-induced platelet aggregation in both.
