Haemorrhagic Gastroenteritis (HGE)

Haemorrhagic gastroenteritis (now often called acute haemorrhagic diarrhoea syndrome) is characterised by sudden onset of bloody diarrhoea and vomiting. It most commonly affects small and toy breed dogs but can occur in any dog. The exact cause is often unknown but may involve bacterial infections, stress, or food allergies.

Symptoms:

• Sudden onset of bloody, jelly-like diarrhoea
• Vomiting, sometimes with blood
• Significant lethargy
• Decreased appetite or refusal to eat
• Abdominal pain
• Dehydration (dry gums, sunken eyes)
• Increased heart rate
• Weakness or collapse in severe cases

Action Steps:

1. Contact your veterinarian immediately.
2. Provide fresh water but do not force food.
3. Collect a sample of the diarrhoea if possible.
4. Keep your pet warm and comfortable during transport.
