Background: The ovariosalpingohysterectomy (OSH) is one of the most performed surgeries in bitches often used in population control. Surgical techniques that decrease the chances of operative complications and cause less nociceptive stimulation and acute pain to the patient are highly sought after by veterinarians. We evaluated the inverted OSH technique (IT), which, after celiotomy, begins with the ligature execution, transection of the uterine body and subsequent ligation and ovarian disinsertion. The purpose of this investigation was to analyze aspects of IT execution in bitches, such as visceral manipulation, access to the uterus and ovaries, and surgical time compared to the traditional technique. Materials, Methods & Results: Inverted OSH was compared to the so-called traditional OSH technique, characterized by the initial removal of the ovaries followed by uterine section. The OSH techniques were performed in 24 healthy animals, with a body condition score of up to six (on a nine-point scale) in dogs aged between seven months and five years. All dogs were from the Birth Control Program of Dogs and Cats of the UFRRJ and were distributed into two groups: traditional technique (TT) and inverted technique (IT). Surgeries and anesthesia were carried out by the same veterinarian crew (surgeon, surgical assistant, and anesthesiologist). OSH techniques were evaluated by the surgeon and surgical assistant using semiquantitative analysis (multiple-choice questionnaire with closed questions that pointed scores related to the ease of uterine and ovarian manipulation, as well as to the level of manipulation of the intestinal and urinary vesicle) and qualitative descriptive methods (report of techniques with the opinion of surgeons and an external evaluator-veterinarian surgeon who attended surgeries). Also, the total surgical time and the indication of a positive analgesic response according to changes in the vital parameters observed by the anesthesiologist during specific moments of the operation were (AU)
