A 9-year old female Doberman Pinscher had a 5-month history of epistaxis. On routine testing of the dog's serum, blockage of the intake tubes of the equipment resulted. At this point, cryoglobulinemia was suspected and was later confirmed to be due to a monoclonal cryoglobulin (IgM), by means of immunochemical studies. Clinical recovery was achieved by use of cytotoxic drugs.
