Hemophilia in dogs is rare and is similar to Hemophila in people. There are two kinds of Hemophilia; Hemophilia A and Hemophilia B. For both variant the blood is missing an important molecule; Factor VIII for Hemophilia A and Factor IX for Hemophilia B. When these molecules are missing the blood is unable to clot and the dog will bleed from even superficial wounds. Hemophilia is more commonly seen in males although the disease is still rare but females are more likely to be carriers. The treatment for Hemophilia can be plasma transfusions containing the missing factor but the disease is incurable and many dogs either die before diagnoses is made or are euthanized due to the cost transfusions.
