Intestinal neoplasia in dogs has low occurrence and represents less than 10% of all malignant neoplasms in this species. Observed clinical signs may include tenesmus, diarrhea, dyschezia, hematochezia, anal prolapse, anorexia, and weight loss. There is a good prognosis when the disease is localized and completely removed, but metastasis can be observed in more advanced cases. This report aims to describe the case of a rectal adenocarcinoma in a dog, which was removed through bilateral pubic and sciatic osteotomy access. The 9-year-old bitch presented anal bleeding, diarrhea and hematochezia with five months evolution. Abdominal ultrasound indicated extensive intraluminal neoformation in the descending portion of the distal colon, with thickening and loss of parietal stratification. Colonoscopy characterized a five centimeters hemorrhagic mass in the rectum. Histopathological examination of the mass fragments diagnosed rectal carcinoma. Abdominal and pelvic computed tomography was performed, which also identified intraluminal neoformation in the rectum, with no signs of obstruction. X-ray showed no signs of lung metastasis and other sorting tests were unaltered. We opted for surgical resection of the mass by bilateral pubic and bilateral sciatic osteotomy, requiring medial celiotomy extension, ensuring access to the affected colon and rectum segments, which were completely removed by enterotomy. The final histopathological evaluation confirmed the intestinal adenocarcinoma diagnosis. The described technique allows for satisfactory exposure of the pelvic cavity, as well as safer access to its structures. In this case, planning and appropriate surgical technique allowed for a complete resection of the neoplasm, providing the patient with long-term quality of life.
