Incidence, indication and prognosis of ovariohysterectomy in dogs in Abeokuta, Nigeria

Abstract

Case records of dogs that underwent ovariohysterectomy at the Veterinary Teaching Hospital, Federal University of Agriculture, Abeokuta (FUNAAB) between January, 2010 and December, 2016 were reviewed to determine the prevalence, indication and prognosis of this surgical condition. Data recorded include breed and age of the dogs at presentation and reason for ovariohysterectomy. Information on type of anaesthetic techniques, outcome of the surgery and occurrence and severity of complications were also noted. Ovariohysterectomy was performed in nine out of two thousand, two hundred and eighty five dogs that were presented during this period. The nine dogs included seven breed types which were Rottweiler (2), Samoyed (2), Alsatian (1), Doberman (1), Boerboel (1), Lhasa apso (1) and Pug (1). Mean age of the dogs presented for ovariohysterectomy was 5.7 ± 2.9 years with the age ranging between 18 months and 10 years. Indications for ovariohysterectomy in the dogs were pyometra (4), ovarian adenocarcinoma (2), transmissible venereal tumour (1), intra-uterine foreign body (1) and elective request (1). Surgical outcome was good in seven of the dogs, while one dog died secondary to hypovolemia after surgery and another dog was euthanized a week after surgery due to poor renal function. Five of the dogs had moderate obesity about six months after surgery, while a dog had mammary adenocarcinoma two years after ovariohysterectomy. It was therefore concluded that elective ovariohysterectomy is not routinely performed in dogs at the Veterinary Teaching Hospital, FUNAAB, while most cases are performed for management of reproductive tract diseases. Further data are required to authenticate or disprove the findings in this study.
