Gastric Dilatation-Volvulus in Dogs

Gastric dilatation-volvulus (GDV), commonly called bloat, is a life-threatening emergency in large and giant breed dogs requiring immediate veterinary intervention.

Key Facts

GDV occurs when the stomach fills with gas and twists on its axis, cutting off blood supply
Large deep-chested breeds including Great Danes, German Shepherds, and Standard Poodles are most at risk
GDV can kill within hours if untreated; it is one of the most urgent veterinary emergencies
Signs include unproductive retching, distended abdomen, restlessness, and rapid deterioration
Surgical correction involves untwisting the stomach and anchoring it (gastropexy) to prevent recurrence
Prophylactic gastropexy can be performed in high-risk breeds to prevent GDV before it occurs
Feeding multiple small meals rather than one large meal may reduce but not eliminate GDV risk

Welfare Considerations

GDV causes rapid-onset extreme distress including severe abdominal pain, circulatory collapse, and death. Dogs experiencing GDV deteriorate within hours, and without emergency surgery, survival is impossible. The suffering is acute and severe. Owners of high-risk breeds should be educated on clinical signs and the need for emergency care. Prophylactic gastropexy at time of neutering offers significant welfare benefit to at-risk individuals by preventing the condition entirely.

What You Can Do

Learn the signs of GDV if you own a large or deep-chested breed dog
Know the location of your nearest 24-hour emergency veterinary clinic
Ask your vet about prophylactic gastropexy for high-risk breeds at time of neutering
Avoid vigorous exercise immediately before and after meals for deep-chested dogs
Consider feeding multiple smaller meals daily to high-risk breed dogs
