Abstract:
Abnormal bleeding following routine orchectomy of a 5-month-old mixed breed was determined to be due to factor VII deficiency. Although pedigree information was unavailable, failure to respond to vitamin K therapy and the absence of a plasma coagulation inhibitor suggested that the factor VII deficiency was likely inherited rather than acquired.
