The objective of this study was to compare the total surgical time, pain score and hemorrhage after ovariohysterectomy (OVH) and bilateral flank ovariectomy (BFOVE) with hemoclips in dogs. OVH was operated on six dogs and BFOVE was performed on six dogs. In BFOVE group, both ovarian pedicle hemostasis applied using hemoclips after removing ovaries. Total surgical time was recorded from starting incision of skin to closure last skin suture. Pain score was measured at 2, 6, 12, and 24 hours after surgery based on University of Melbourne Pain Scale (UMPS). Hemorrhage around clipping area, uterus, abdominal muscles, and skin were monitored after surgery. BFOVE technique could reduce total surgical time and pain after surgery. There was no hemorrhagic problems near ovarian pedicles following surgery. BFOVE with hemoclips could be useful and recommended for sterilization in dog.
