Background: Perineal hernia is characterized by the displacement of abdominal organs to the perineal region after ruptureor weakening of the pelvic diaphragm muscles. This condition is common among middle-aged and elderly unneuteredmale dogs. Considering the severity of the condition and its rarity among bitches, this paper reports on a case of perinealhernia caused by hydrometra in a 12-year-old pinscher bitch.Case: The patient was a 12-year-old Pinscher bitch, weighing 3 kg, suffering from anuria and constipation in the 36 hprior to treatment, without reported trauma. She was unspayed, and her last estrus had occurred approximately thirty dayspreviously. The physical examination revealed an increase in volume in the right perineal region, increased volume in theleft inguinal region, increased body temperature (39.8ºC), pale mucous membranes, tachycardia, tachypnea, abdominalpain and increased popliteal lymph nodes. The diagnosis was determined based on her medical history, clinical signs andan ultrasound scan, which revealed dilated uterine horns displaced unilaterally in the left inguinal region, with evidence ofhydrometra, full urinary bladder inside the hernia sac in the right dorsolateral perineal region and right kidney pyelectasis.After evaluating the animals physical condition, surgery was recommended, involving ovariohysterectomy associatedwith inguinal and perineal herniorrhaphy.Discussion: Perineal hernia, a common condition in male dogs, is characterized by the displacement of organs towardsthe perineal region. However, in this case, this condition occurred in female dog. Unlike males, the main causes of perineal hernia in females are trauma, chronic coughing related to heart disease, bronchitis, and tracheal collapse. Increasedintra-abdominal pressure associated with a weak pelvic diaphragm predisposes for herniation of abdominal contents,such as occurred through hydrometra. In this case...(AU)
