Plain-English summary
A 10-year-old Yorkshire Terrier was diagnosed with a rare type of rectal cancer called tubulopapillary adenocarcinoma. After surgery to remove the tumor, the cancer unfortunately spread to other parts of the body, including the intestines, bladder, kidneys, lymph nodes, liver, and lungs, within six months. The dog's prognosis was affected by the extent of the cancer's invasion and its ability to metastasize. Sadly, despite the initial surgery, the cancer's aggressive nature led to a poor outcome.

Abstract
ABSTRACT Intestinal carcinomas are rare in dogs. The prognosis and survival time are dependent of the histological type, the invasion of the intestinal wall by the malignant cells and the ability of primary neoplasm to produce metastasis. This study reports a case of a Yorkshire dog that developed a rectal tubulopapillary adenocarcinoma progressing to a peritoneal carcinomatosis and multiple metastasis in large intestines, bladder, kidney, iliac lymph node, liver and lungs, six months after transanal surgical resection of the primary rectal neoplasm. Clinical, surgical, pathological and immunophenotypic findings are described. COX-2 imunohistochemical score was higher in hepatic metastasis (score 9) than in the primary tumour (score 6), and the growth fraction (Ki-67) observed was of 49.2% in the rectal neoplasm.
