A 5-year-old female fennec fox weighing 1 kg presented to the Veterinary Medical Center, Chungbuk National University with swelling of the mammary glands and hematuria. There were no significant complete blood count (CBC) or serum chemistry findings. The uterus obtained by ovariohysterectomy was filled with blood-clot-like material. The uterine fluid contained erythrocytes, a few leukocytes, and bilirubin crystals without bacteria. The progesterone concentration in the blood serum the day before ovariohysterectomy was 7.3 ng/ mL, which is higher than anestrus and lower than a true pregnant condition in a fennec fox. Despite the low blood progesterone concentration and absence of a fetus in the uterus, the histopathological zonary placental findings indicated that the fennec fox had been pregnant. This is the first case report of hematometra associated with fetal death in a captive fennec fox.
