Dog Gastric Dilatation Volvulus Prevention

Gastric dilatation-volvulus (GDV) is a rapidly fatal emergency in large deep-chested dogs that requires immediate surgery, with preventive strategies reducing risk.

Key Facts

GDV affects large and giant deep-chested breeds including Great Danes, German Shepherds, and Standard Poodles
The stomach fills with gas and rotates, cutting off blood supply and causing shock within hours
Mortality without surgery exceeds 50% and can occur within hours of onset
Prophylactic gastropexy during neutering or other procedures prevents recurrence in high-risk breeds
Feeding from elevated bowls was once recommended but evidence suggests this may increase risk

Welfare Considerations

GDV causes severe pain from gastric distension and rapidly progresses to shock and death. Dogs experience acute agony before collapse. The speed of deterioration means that owner recognition and emergency response are critical welfare determinants. Owners of high-risk breeds should know the signs and have an emergency plan. Prophylactic gastropexy eliminates the risk of rotation and is a highly welfare-positive intervention for predisposed breeds.

What You Can Do

Learn to recognise GDV signs: unproductive retching, distended abdomen, restlessness, and rapid deterioration
Seek emergency care immediately - GDV is always a veterinary emergency
Discuss prophylactic gastropexy with your vet when your large-breed dog undergoes any abdominal surgery
Avoid vigorous exercise immediately before and after meals
Know the location of your nearest 24-hour emergency veterinary clinic
