Plain-English summary
A 6-year-old male crossbred Maltese was brought in for bleeding issues due to a condition called hemophilia B, which affects blood clotting. Blood tests showed that his clotting time was significantly longer than normal, indicating a problem with his blood's ability to coagulate. After receiving blood transfusions, the dog has been able to manage his bleeding problems effectively for over two years, despite experiencing episodes of hemorrhage every few months.

Abstract
A crossbred Maltese dog, 6-year-old, male, was presented to us for examination due to coagulopathy. On examination of blood coagulation screening tests, activated partial thromboplastin time (APTT) was markedly prolonged (63.6 sec). Therefore, a defect in the intrinsic pathway of coagulation was suspected. An additional serum test was also examined and APTT was returned to within the normal range. Furthermore, factor IX coagulation activity was markedly low (2.3%). On the basis of these results, the dog was diagnosed with hemophilia B. The dog has since been presented to us because of hemorrhage problems again after 5, 10, and 16 months, but blood transfusions have maintained good control of its coagulopathy for more than two years.
