Thrombopathia is an inherited platelet disorder. Affecteddogs have abnormal platelet function because they are not able to stick together properly and therefore cannot form a clot. Dogs exhibit typical signs of platelet defects including bleeding from snouts, gingival bleeding,and petechiation. Other symptoms include weakness and rear limb paralysis secondary tospinal cord hemorrhage. The platelet defect is characterized by impairedor absent platelet aggregation responses to all agonistsexcept thrombin; blood coagulation is delayed due to thrombin respond delay occurring in 5-6 minutes instead in 2-3 minutes. Thrombopathia has been reported in different dog breeds including Basset hound, Landseer and American Eskimo dog. Different mutations in genes of all mentioned breeds lead to thrombopathia with similar symptoms.
