Hormonal induction of abortion of a mummified fetus in a breeding weimaraner bitch

The case describes a four-year-old Weimaraner bitch with fetal death resulting in the resorption of two gestation sacks and mummification of a fetus on day 30 of gestation. An ultrasound diagnostic on the 22nd day post-ovulation showed three normal gestation sacks. An ultrasound check-up 3 days later showed only one gestation sack with no heartbeat observed, while the diameter of the gestation sack did not correspond to the gestation period. The uterine wall was intact and the ovaries had corpus luteum bilaterally. The clinical status of the patient was physiological. On the 32nd day post-ovulation, an ultrasound showed a big solid cyst on the left ovary. At the bifurcation of the uterus, there was a solid mass (2.56 cm x 3.18 cm) with a lack of fetal fluid. The mass corresponded to mummified fetus. The progesterone level on day 34 of gestation was 31.94 ng/mL. The bitch was negative for Canine herpes virus, Canine bocavirus and Brucella canis. The induction of the abortion started on day 34 post-ovulation with a combination of antiprogestine (Alizine® and synthetic prostaglandins, (Estrumate®) given subcutaneously and intravaginally administered (Cytotec®). There were certain side effects during therapy, such as tachypnea, polydipsia, nesting and fever. During therapy, the uterine wall, embryo mass, ovaries and eventual occurrence of fluid in the lumen of the uterus were monitored daily. On the 57th day post-ovulation, a mucosal dark discharge occurred. Ultrasound findings showed no presence of fetal mass persistence in the uterus. The bitch showed signs of heat three and half months after the abortion. In the next gestation, it was confirmed by ultrasound that a minimum of five vital fetuses were developing normally. It can be concluded that the described hormonal protocol is the option of choice for breeding bitches in order to avoid unnecessary and undesirable surgery.
