Gastric Dilatation-Volvulus (GDV), commonly called bloat, is the #1 life-threatening emergency for large and giant breed dogs. The stomach fills with gas (dilatation) and then twists on its axis (volvulus), trapping the gas and cutting off blood supply to the stomach and spleen. Without emergency surgery, GDV is fatal within hours. Every dog owner of an at-risk breed must know these signs.

At-Risk Breeds

Great Danes (highest risk — 42% lifetime incidence), German Shepherds, Standard Poodles, Weimaraners, Irish Setters, Boxers, Dobermans, Saint Bernards, and any deep-chested large or giant breed dog. Risk increases with age and having a first-degree relative who bloated.

Emergency Signs (R.E.T.C.H.)

Restlessness and pacing — cannot get comfortable
Enlarged/distended abdomen — may be visible or subtle; the abdomen will be tight like a drum
Trying to vomit — unproductive retching (gagging with nothing coming up or only white foam)
Collapse, pale gums, rapid heart rate — signs of shock setting in
Hunched posture, looking at abdomen, praying position (front down, rear up)

Timeline

GDV progresses rapidly. From first sign to critical shock: 30-90 minutes. Do NOT wait to see if it resolves. Do NOT try home remedies. Every minute the stomach remains twisted, more tissue dies. Survival rate with prompt surgery: 80-90%. Survival rate without surgery: 0%.

Treatment Cost Estimate

Emergency GDV surgery with gastropexy: $3,000-$7,500 depending on location, after-hours fees, and whether splenectomy is needed. Pet insurance typically covers GDV if enrolled before any pre-existing conditions. Prophylactic gastropexy (preventative stomach tacking during spay/neuter): $300-$800 — recommended for all at-risk breeds.
