Hemorrhagic Gastroenteritis In Dogs

Hemorrhagic Gastroenteritis In Dogs

Hemorrhagic Gastroenteritis (HGE) is a multifactorial disease characterized by chronic inflammation of a dog's intestinal tract distinguished by sudden onset of profuse bloody diarrhea and vomiting.

Hemorrhagic gastroenteritis - medically known as Acute Hemorrhagic Diarrhea Syndrome (AHDS) - typically affects small breed dogs and young to middle-aged dogs. The clinical course involves a per-acute onset of clinical signs that may lead quickly to death without prompt therapy.

Although AHDS has similar symptoms to other causes of bloody diarrhea, such as pancreatitis and parvovirus, it is a unique condition that occurs with explosive diarrhea together with a prominent packed cell volume (PCV) of at least 60%. Although the etiology is unknown, it has been thought that uncharacteristic immune responses to bacteria such as (Clostridium perfringens), Pancreatitis, Bowel cancer in older dogs, and Inflammatory bowel disease.

While it is certainly daunting to see your dog having bloody diarrhea and vomiting, immediate medical intervention can be of paramount importance and have a good prognosis.

Anti-inflammatory and Immunosuppressive Therapy: Prednisolone or Prednisone, Cyclosporine, Chlorambucil, Budesonide, or Sulfasalazine.

Dietary Management:

  1. Switch over to a diet that leads to antigenic modification (eg, protein hydrolysate, novel protein source).

  1. Causes:

The HGE etiology is not understood properly. Indeed, it appears to have several causes.

Whatever may be the cause, the outcome is the inflammation of the lining of the large intestine.

However, possible causes include:

  • Abnormal immune response due to bacterial or parasitic infection.
  • Hypersensitivity to a specific protein in their food.

Other Factors include:

  • Genetics
  • Microbial factors
  • Inflammatory bowel disease
  • Pancreatitis
  • Bowel cancer in older dogs
  • Environmental factors
  1. Mortality:

He has a sudden onset and it is destructive. Without proper treatment, the condition can be life-threatening.

  1. Diagnosis:
  • A complete blood count (CBC).
  • Electrolyte tests
  • Pancreas tests to rule out pancreatitis.
  • Colonoscopy tests
  • X-rays and Ultrasound
  • Viral infection tests to rule out viral infections.
  • Fecal smears/cultures/PCR testing.
  1. Prognosis:

The degree of the infection depends on the age, any coexisting infections, and the immune response of the host. The prognosis for HGE is really good. Most dogs undergoing treatment will recover within a few weeks. If left untreated, HGE can be fatal for dogs, especially for puppies, so head to your vet immediately.
