Haemorrhagic Gastroenteritis (HGE)

Also known as Acute Haemorrhagic Diarrhoea Syndrome (AHDS)

Haemorrhagic gastroenteritis is an idiopathic disease, which means that its exact cause is often unknown. HGE occurs when large amounts of fluid seep into the gut.

HGE can occur in dogs of any age or breed. It is more commonly diagnosed in Labrador Retrievers, Miniature Pinschers, Miniature Schnauzers, Miniature Poodles, Maltese and Yorkshire Terriers.

The average age of dogs diagnosed with the condition is around five years, and many cases occur without warning.

All dogs may develop HGE regardless of their age, size or breed, although small dogs may be at greater risk. Dogs with a history of digestive sensitivity may also experience the condition more frequently.

Some veterinary clinics report more cases during holiday periods, when dogs may have greater access to rich human food and treats. Dogs that raid leftovers, bins or food waste may also be at increased risk of digestive illness.

HGE may also be associated with toxins or immune-mediated disease. In some cases, hyperactivity, anxiety and stress may contribute to the condition.

Other possible causes or associated conditions include:

• Trauma
• Foreign bodies in the digestive system
• Intestinal parasites or bacteria
• Blood-clotting disorders
• Ulcers in the stomach or intestines

Although it is often impossible to identify a specific cause, dogs that have previously suffered from HGE may be more likely to experience the condition again.
