“…Laparoscopic ovariectomy in dogs during late gestation is similar to the medical protocols for termination of pregnancy as it resulted in a precipitous drop in serum progesterone and eventually fetal death and expulsion. Similarly, signs noted during uterine evacuation following laparoscopic ovariectomy such as vulvar discharge, transient anorexia and mammary congestion were consistent with signs reported for medical termination of pregnancy in dogs [26, 28]. In the present study, 88% fetuses were noted to be dead 24 h following laparoscopic ovariectomy and prior to expulsion; all fetuses were noted to be dead at expulsion and complete uterine evacuation occurred between 1 and 3.5 days.…”

“…[23–25] However to the authors’ knowledge no guidelines exist for induction of fetal death prior medical termination of pregnancy in dogs and may warrant further research. Several drug protocol have been evaluated for termination of pregnancy in mid-late gestation in dogs (≥40 days) all eventually leading to withdrawal of the activity of progesterone resulting in fetal death, followed by abortion [26–28]. Medical protocols recommended for use in dogs in mid-late gestation involve 3–10 days of daily treatment and commonly result in termination of pregnancy, like in the present study, between 40 and 50 days of gestation [26–28].…”

“…Concerns following medical termination of pregnancy protocols, apart from drug related side-effects, are treatment failure resulting in persistence of luteal tissue and maintenance of adequate progesterone levels resulting in partial abortion and fetal retention [26, 28]. Laparoscopic ovariectomy enables removal of both ovaries and thus ensures complete withdrawal of progesterone function and uterine evacuation.…”

BackgroundSurgical sterilization of stray dogs is the most widely used technique to control stray dog population. Although ovariectomy is an effective technique for elective sterilization of female dogs, most stray dog population control programs generally utilize ovariohysterectomy for spaying female dogs. In the context of stray dog sterilization, laparoscopic ovariectomy has been utilized and reported to be cost-effective compared to programs utilizing open surgical approaches. However, when pregnant stray dogs are encountered either conventional ovariohysterectomy is performed or surgery is deferred altogether. It is reported that ovariectomy at any stage during canine pregnancy results in fetal resorption or abortion, however, clinical outcomes following laparoscopic ovariectomy in dogs in late gestation have not been previously reported. The purpose of this study was to investigate the outcome of laparoscopic ovariectomy with intra-gestational sac injection (IGSI) of potassium chloride (KCl) in dogs in late gestation.ResultsEight client owned dogs in the gestational age range of 40–50 days underwent laparoscopic ovariectomy with IGSI of KCl. Laparoscopic ovariectomy resulted in decreased serum progesterone from 11.6 ± 2.6 ng/ml on day 0 to 1.3 ± 0.4 ng/ml 24 h’ post-surgery. IGSI of KCl did not result in immediate fetal death and fetal death temporally closely followed the drop in serum progesterone noted 24 h post-ovariectomy. Viscous brown vulvar discharge preceded fetal expulsion by 12 h and all the fetuses were dead when expelled. Uterine evacuation was documented within 45 ± 20 h (1–3.5 days) in all dogs without any clinically significant complications.ConclusionLaparoscopic ovariectomy enables elective termination of pregnancy and simultaneous neutering of dogs in late gestation and has potential applications in high volume stray dog sterilization programs which utilize laparoscopy. Utility of IGSI of KCl in this regard is unclear.

Pregnancy termination is a required procedure in companion animal practice. In healthy bitches with confirmed pregnancy, good results are obtained with the combination of prostaglandin F 2 and dopamine agonist, followed by regular sonographic examination until confirmed abortion. The aim of this study was to establish a simple and easily applicable procedure, with different dynamics of application of dinoprost and cabergoline. Dinoprost was administered intramucousally in the vestibule of vagina. Twenty bitches were divided into four equal groups. Group A received dinoprost and cabergoline daily; group B received dinoprost every 48 h and cabergoline daily; group C received dinoprost daily and cabergoline every 48 h, and group D received both cabergoline and dinoprost every 48 h. The treatment lasted until abortion was sonographically confirmed. The pregnancy was successfully terminated in all bitches, and side effects appeared in 90% animals, though they were of strong intensity in only 15% of bitches. Dinoprost administered intramucousally was effective with fewer undesirable, strong, systemic side effects. Drug administration every 48 h also induced abortion, with negligible side effects, but with slightly longer duration of treatment. This combination could be interesting in cases with time-limited owners and in countries where other drugs are unavailable.
