Plain-English summary
An 11-year-old neutered male German shepherd was brought to the vet because he was not eating, had severe watery diarrhea, and was losing weight. Tests revealed that he had a rare type of colon cancer called adenocarcinoma, which had spread throughout his large intestine and to other parts of his body, including lymph nodes and lungs. Unfortunately, due to the advanced stage of the cancer, treatment options were limited, and the prognosis was poor. This case highlights the importance of early detection of gastrointestinal symptoms in dogs.

Abstract
Canine colonic intestinal adenocarcinoma typically presents as rectal polypoid or annular stenotic masses causing clinical signs consistent with large bowel disease. This report discusses an unusual case of intestinal adenocarcinoma in an 11-year-old, neutered male German shepherd dog presented for evaluation of anorexia, profuse watery diarrhea, and weight loss. In this dog, colonic adenocarcinoma diffusely infiltrated the entire large bowel and caused an annular fusiform lesion, as confirmed by endoscopic biopsies and postmortem examination. Other unique features included a paucity of desmoplasia associated with the neoplastic lesion and widespread metastasis to regional lymph nodes, lung, and prostate.
