An eight‐year‐old, sexually intact, male, 37 kg crossbred dog was referred for investigation of two acute episodes of intestinal bleeding and severe anaemia within a five‐month period. There was no evidence of coagulopathy or underlying systemic disease. Technetium‐labelled red blood cell scintigraphy suggested the colon as the site of bleeding. Colonoscopy identified a focal area of dilated and tortuous mucosal blood vessels. Histopathology of the resected colon revealed vascular ectasia (angiodysplasia). At nine months post‐resection, the dog remained healthy and free of any overt intestinal haemorrhage.
