Thrombopathia is a genetic disease that affects platelet function. In thrombopathia, platelets are unable to stick together properly and therefore cannot clot normally. The most common symptoms of this condition are recurrent nosebleeds and excessive bleeding from the gums and bruising. Internal bleeding and black or red stools may also be observed. Although dogs with this condition are at risk for spontaneous bleeding and internal bleeding, affected dogs may not be identified until surgery is performed or trauma occurs.
