A nine-year-old dog with a three-month history of frequent mucosal, bloody stool and vomiting was referred to our hospital. An abdominal mass was palpated. Ultrasonography and computed tomography revealed the mass in the descending colon. It was removed surgically, and was diagnosed as a high-grade malignant lymphoma histopathologically. The dog was treated according to the University of Wisconsin-Madison (UW25) protocol. A follow-up CT scan showed no relapse on day 449, and the dog has been in good condition more than two years after surgery. There are many reports of dogs with a colorectal lymphoma surviving for a long period of time, and this is another example of such long survival.KEY WORDS : alimentary lymphoma, colon, dog(J Anim Clin Med. 23(4)162-165, 2014)
