The preoperative course of therapy was continued, but the bitch died 12 hours later. Ovariohysterectomy and partial vaginectomy were performed. A recent rupture in the vaginal wall, approximately 6 cm long, was observed. Once a male dog is fertile, they are capable of mating all year round. Larger breeds may reach sexual maturity a little later than small breeds. While male dogs do not go into heat, they become fertile around 6 months. After exploratory laparotomy the protruding organs, which were in good condition, were reduced. The term ‘in heat’ refers specifically to the time when a female dog is receptive to mating with males. Females go into estrus heat and with that, the urge to mate is strong. Antimicrobial and analgesic drugs were also administered. Dogs whose reproductive organs are intact into adulthood are prone to certain behaviors. Stabilisation of the dog's general condition was attempted before surgery. The laboratory findings included moderate anaemia, leukocytosis, hypoalbuminaemia, azotaemia and elevated liver enzyme activities. The abdominal viscera were flushed with warm sterile saline solution, protected and maintained wet. A true vaginal prolapse was also observed. Intestinal loops, the urinary bladder and the uterine horns and body were protruding from the vulva. Thus, to pass a speculum or catheter into the vagina requires that it be initially oriented at this upward angle, and if a female needs assistance expelling a puppy from the pelvic canal, best results are obtained when gently pulling in this mostly-downward direction. The dog was in poor body condition, dehydrated, hypothermic, depressed, non-ambulatory and in a state of shock. Anatomy and physiology of the female dog The vaginal vestibule, a short entryway into the vagina, is oriented at a 60-degree angle to the horizontal (upward, toward the spine, and forward, toward the head). Parturition had occurred at low ambient temperature, and only one puppy survived out of the seven oversized fetuses. A 1.5-year-old German Shepherd mixed breed dog was admitted with mild haemorrhage from the vulva and a perineal mass of 24-hour duration, which had been first observed immediately after parturition.
