Cervical duplication in dogs

Two maiden bulldogs with cervical duplication were presented for breeding management. Dogs were successfully impregnated via endoscope-assisted transcervical insemination (TCI) and had their litters via cesarean surgery. A common uterine body between 2 cervical openings and 2 uterine horns was noticed (with no other reproductive abnormalities) at surgery. Duplication of the cervix has apparently not been previously described in dogs. With TCI becoming a more frequently used method of breeding, it is probable that defects involving failed or incomplete fusion of the paramesonephric duct during embryological development will be more frequently observed by clinicians.
