Horses April 15, 2013 Print Friendly and PDF

Hemophilia A is an inherited disease of Thoroughbreds, Quarter Horses, Arabians, and Standardbreds. The disease is transmitted by an X-linked mode of inheritance. Hemophilia A is characterized by prolonged bleeding times in affected males. These horses have a tendency to develop hematomas (blood pockets) whenever traumatized.
