Hemorrhagic gastroenteritis

Hemorrhagic gastroenteritis

Hemorrhagic gastroenteritis (HGE) is a disease of dogs characterized by sudden vomiting and bloody diarrhea. The symptoms are usually severe, and HGE can be fatal if not treated. HGE is most common in young adult dogs of any breed, but especially small dogs such as the Toy Poodle and Miniature Schnauzer.cite book|author=Ettinger, Stephen J.;Feldman, Edward C.|title=Textbook of Veterinary Internal Medicine|edition=4th ed.|publisher=W.B.

The cause is uncertain. Suspected causes include abnormal responses to bacteria or bacterial endotoxin, or a hypersensitivity to food.cite web | title = Hemorrhagic gastroenteritis | work = The Merck Veterinary Manual | date = 2006 | url = http://www.merckvetmanual.com/mvm/index.jsp?cfile=htm/bc/23311.htm | accessdate = 2007-03-20 ] Pathologically there is an increase in the permeability of the intestinal lining and a leakage of blood and proteins into the bowel. "Clostridium perfringens" has been found in large numbers in the intestines of many affected dogs.

igns and symptoms

Profuse vomiting is usually the first symptom, followed by depression and bloody diarrhea with a foul odor. Severe hypovolemia (low blood volume) is one of the hallmarks of the disease, and severe hemoconcentration (a very high hematocrit) is considered necessary for diagnosis. The progression of HGE is so rapid that hypovolemic shock and death can occur within 24 hours. Disseminated intravascular coagulation (DIC) is a possible sequela of HGE.


Symptoms of HGE and canine parvovirus (CPV) are similar enough that they need to be differentiated. HGE is different from CPV in that there is no fever or low white blood cell count, and that there is a high hematocrit. A negative fecal parvovirus test is sometimes necessary to completely rule out CPV. Other potential causes of vomiting and diarrhea include gastrointestinal parasites, bacterial infections including "E. coli", "Campylobacter", or "Salmonella", protozoal infections such as coccidiosis or giardiasis, and gastrointestinal cancer.


The most important aspect of treatment of HGE is intravenous fluid therapy to replace lost fluid volume. The vomiting and diarrhea are treated symptomatically and will usually resolve after one to two days. Antibiotics targeting "C. perfringens" are also used. With prompt, aggressive treatment, the prognosis is good. There is less than 10 percent mortality with treatment, but 10 to 15 percent of cases will recur.
