Dog GDV: Gastric Dilatation-Volvulus Emergency Care

Gastric dilatation-volvulus (GDV) is an acute, life-threatening emergency in large and giant breed dogs where the stomach fills with gas and twists, requiring immediate surgical intervention.

Key Facts

GDV kills within hours without treatment; it is among the most urgent emergencies in veterinary medicine
Large deep-chested breeds including Great Danes, German Shepherds, and Standard Poodles are most at risk
The stomach dilates with gas and then twists, cutting off blood supply to the stomach wall and spleen
Signs include unproductive retching, abdominal distension, restlessness, drooling, and rapid deterioration to shock
Prophylactic gastropexy — surgically attaching the stomach to the body wall — reduces recurrence risk by over 95 percent
Mortality rates with prompt treatment are approximately 10-33 percent; delay dramatically worsens outcomes

Welfare Considerations

GDV causes extreme suffering: the distended, twisted stomach is acutely painful, and the resulting cardiovascular shock causes profound distress. Dogs deteriorate rapidly and die in extreme discomfort without emergency surgery. The welfare imperative is to treat this as an absolute emergency — every minute of delay worsens the welfare outcome and prognosis. For owners of at-risk breeds, knowing the signs and having a 24-hour emergency clinic identified in advance is critical. Prophylactic gastropexy during routine neutering is now widely recommended for at-risk breeds, and has a strong welfare case — preventing one of the most severe welfare emergencies dogs experience.

What You Can Do

Discuss prophylactic gastropexy with your vet if you own a large deep-chested breed — it can be done during neutering
Know the location of your nearest 24-hour emergency veterinary clinic before an emergency arises
Learn to recognise early GDV signs: unproductive retching and abdominal bloating are emergency signals
Avoid vigorous exercise immediately before and after meals in at-risk breeds to reduce triggering risk
