Acute paraplegia in a puppy with hemophilia A

A seven-week-old, male chow chow-keeshond cross puppy was presented with acute paraplegia and episcleral hemorrhage. An X-linked, hereditary coagulopathy was suspected and confirmed by clotting factor analysis and necropsy findings of intraspinal hemorrhage. In young, male puppies with acute spinal pain and long-tract signs, intraspinal hematoma secondary to inherited X-linked coagulation factor deficiencies should be considered in the differential diagnosis.
