Abstract

Seven bitches of various breeds presented at the VCC, Junagadh with the anamnesis of persistent vaginal bleeding since 30 to 45 days  were included in this syudy. They were all subjected to a vaginal cytology, which showed that there were a lot of superficial cells (>80%).  Given the vaginal cytological cellular profile, the presumptive diagnosis was made for the prolonged estrus, may be due to either  follicular cysts or persistent anovulatory follicles. To induce ovulation or luteinization, the animals were treated with human chorionic  gonadotrophin twice at 24-h intervals at a dose of 22 IU/kg body weight. After receiving an hCG injection, the vaginal bleeding in six of the  treated animals decreased every day and almost ceased in five days, but in one instance, the bleeding continued. The recommendation  for this bitch was an ovario-hysterectomy.
