Case

A 9-year-old neutered male Labrador retriever is presented with a 16-hour history of hemorrhagic diarrhea. Prior to arrival at the clinic, the dog had been quiet, refused food, vomited bile once, and produced a large volume of bloody diarrhea before collapsing at home. On physical examination, mental status is depressed (ie, dull), mucous membranes are tacky and pink, capillary refill time is prolonged, and skin elasticity is reduced. Thoracic auscultation reveals a heart rate of 140 bpm with no murmur detected. Abdominal palpation elicits mild discomfort, but no abnormal structures are felt. Rectal temperature is 101.6°F (38.7°C). Packed-cell volume is 61%. Acute hemorrhagic diarrhea syndrome (AHDS) is diagnosed.
