Gastric dilatation-volvulus, commonly called bloat or GDV, is one of the most time-sensitive emergencies in veterinary medicine. The stomach fills with gas and fluid (dilatation) and may twist on its axis (volvulus), cutting off blood supply to the stomach wall and spleen. Without emergency intervention, circulatory shock, tissue death, and cardiac arrhythmias can be fatal within hours.

Which dogs are at risk

Deep-chested, large and giant breeds are most susceptible. Great Danes, German Shepherds, Standard Poodles, Irish Setters, and Weimaraners top the list, but any dog can develop GDV. Risk factors include eating one large meal per day, eating rapidly, exercise immediately after meals, stress, and a family history of bloat. Dogs over the age of seven face increased risk regardless of breed.

Recognizing the signs

A dog with GDV may appear restless and unable to settle. The abdomen often looks distended and feels tight when tapped. Unproductive retching, where the dog tries to vomit but nothing comes up, is a hallmark warning sign. Excessive drooling, rapid breathing, weakness, and pale gums indicate progressing shock. Collapse may follow quickly.

Emergency response

This is not a wait-and-see situation. Transport your dog to an emergency veterinary hospital immediately. Call ahead so the team can prepare. Do not attempt to relieve the gas at home. Time is the most critical factor; survival rates drop significantly with every hour of delay.

Veterinary treatment

Emergency stabilization includes intravenous fluids, pain management, and stomach decompression. If volvulus is confirmed on imaging, surgery is required to untwist the stomach, assess tissue viability, and perform a gastropexy, which tacks the stomach to the abdominal wall to prevent recurrence. Post-operative monitoring for cardiac arrhythmias is standard for 48 to 72 hours.

Prevention strategies

Feed two or three smaller meals instead of one large meal. Use slow-feeder bowls for dogs that gulp food. Avoid vigorous exercise for at least an hour after eating. Discuss prophylactic gastropexy with your veterinarian, especially for high-risk breeds. This procedure can be performed during spay or neuter surgery.
