Laparoscopic ovariectomy results in fewer complications than open ovariohysterectomy in bitches, study finds

21 August 2025

Female dogs neutered by laparoscopic ovariectomy experience fewer postoperative complications and unusual behaviours in the days following surgery compared to those undergoing more traditional open ovariohysterectomy via celiotomy, according to new research.

The new study, partly funded by BSAVA PetSavers and published in the Journal of Small Animal Practice, is the first to compare peri- and postoperative complications, behaviour after surgery, and surgery duration, for the two most common neutering procedures for female dogs; laparoscopic ovariectomy (LAP-OVE) and open ovariohysterectomy (celiotomy) (OVH-CEL). Researchers from the University of Nottingham School of Veterinary Medicine and Science, Guide Dogs and Feldon Veterinary Centre analysed data from 519 bitches neutered by either LAP-OVE or OVH-CEL at four UK veterinary practices.

Fewer bitches developed wound redness or swelling at the surgical site following LAP-OVE (16%), compared to those that underwent OVH-CEL (36%). Intraoperative complications were reported for 2% of dogs neutered by LAP-OVE and 3% of those neutered by OVH-CEL. Postoperative complications were reported for 0.5% of the LAP-OVE group and 1% of the OVH-CEL group.

Unusual behaviours (inappetence, discomfort, licking or chewing) in the postoperative period were less common in dogs neutered by laparoscopic ovariectomy. There was no significant difference in surgical duration between the two techniques.

The findings add to a growing body of evidence suggesting that postoperative complications, including those related to wound healing and those requiring further veterinary intervention, are lower for laparoscopic than open surgeries for bitches neutered by experienced veterinarians.

Lead author, Dr Rachel Moxon, said: “While there is already evidence from other studies relating to complications following neutering surgeries in bitches, this is the first time that the outcomes have been compared between what are anecdotally reported to be the two most frequently performed neutering surgeries for female dogs in the UK. The results will be of interest not only to vets, but for pet owners and others that have to make choices about neutering their dogs. Understanding the surgical risks is an important factor to consider, and decision making is made easier when it can be informed by evidence”.

The study was partly funded by BSAVA PetSavers, the grant awarding arm of the British Small Animal Veterinary Association. It has invested more than £2.7 million in vital clinical research and training programmes over the past 50 years to advance clinical investigations into pet animal medicine and surgery.
