Plain-English summary
A 6-year-old male Collie was brought to the vet with symptoms of difficulty passing stool, intermittent diarrhea, and occasional blood in the stool. After examination, the vet diagnosed colorectal polyps, which are growths in the colon that can cause these issues. The vet removed the polyps through surgery, and while the prognosis was generally good, some polyps showed signs that could lead to cancer in the future. It's important for pet owners to monitor their dogs for similar symptoms and consult their vet if they notice any changes.

Abstract
Seventeen cases of colorectal polyps in the dog were seen at the Ontario Veterinary College over a 12-year period. The mean age of occurrence was 6.9 years, and males and females were almost equally affected. The Collie was the most frequently affected breed (4/17). The clinical signs were typically dyschezia, periodic intermittent diarrhea and melena, and rectal prolapse of the polyp. The histopatholic classifcation were hyperplastic polyp (1), papillary adenoma (1), tubular adenoma (4), papillotubular adenoma (10), and unclassified (1). Severe epithelial atypia, likely carcinoma in situ, was apparent in 5 of the papillotubular adenomas. Retrospective analysis of survival data after polypectomy suggested a good prognosis, but the results were inconclusive and it is possible that some of the polyps represented premalignant lesions. Large polyps (greater than 1 cm in diameter) frequently had marked epithelial atypia and were considered more likely to recur or to become malignant.
