This study aimed to evaluate 120 cases of perineal hernia treated at the Veterinary Hospital of Uberaba (HVU)from 2005 to 2020, addressing the clinical and surgical aspects and the postoperative period, seeking to identify the mostrelevant factors to improve care and treatment of future patients affected by this disease.Materials, Methods & Results: The medical records of dogs with a definitive diagnosis of perineal hernia were collected.The prevalence of perineal hernia was calculated. Data were obtained regarding sex, being castrated or not, age, bodymass, race, clinical signs, affected side, possibility of hernia reduction, treatments used, associated pathologies. Of the 120cases, only 69 underwent surgery at the HVU and from these cases data were obtained regarding hernia content, surgicaltechniques, surgical wires used, recurrences and postoperative complications. Fishers exact test was applied to assess theinfluence of the type of surgical treatment and surgical thread on the occurrence of complications and recurrences. Perineal hernia was the second most frequently observed hernia. Mixed breed, male, non-neutered and geriatric dogs were themost affected. The most frequently observed clinical signs were related to the digestive and urinary tract, consistent withthe most commonly found hernia contents (bladder, prostate and rectum). The simple herniorrhaphy technique was themost used and showed a high number of complications. The second most used technique was...(AU)
