Bloat in dogs (GDV) — recognise it in 60 seconds, act in 90 minutes

The 60-second test

Look at your dog right now. Three questions:

1. Is the abdomen visibly distended — taut, drum-like, larger than usual?
2. Is the dog trying to vomit but nothing comes up (unproductive retching)?
3. Is the dog restless, pacing, or unable to settle?

If yes to two or more of these in a deep-chested breed: do not finish reading this article. Drive to your nearest emergency vet clinic. Phone ahead while someone else drives. The next 90 minutes determine survival.

Breeds at highest risk

GDV preferentially affects deep-chested, large-breed dogs. The strongest associations are with:

• Great Dane (lifetime risk approaching 40%)
• Standard Poodle
• Weimaraner
• Saint Bernard
• Irish Setter
• Gordon Setter
• Doberman Pinscher
• German Shepherd
• Boxer
• Akita
• Newfoundland

In India, where these breeds are increasingly common as urban companions, GDV is now seen weekly in metro emergency clinics. Smaller breeds and mixed breeds are not immune but are far less likely.

The four cardinal signs

Memorise these. Most owners who lose a dog to GDV later say they noticed at least two of these signs but did not put them together:

1. Distended abdomen. The classic sign. The belly looks taut, drum-shaped, sometimes asymmetric (one side more distended than the other). In thinner dogs it can be visible from across the room; in heavier dogs you may need to feel.
2. Unproductive retching. Repeated attempts to vomit producing only foam, saliva, or nothing at all. The stomach has rotated, so the contents cannot exit through the oesophagus. This sign alone, in a deep-chested breed, is enough to warrant emergency vet evaluation.
3. Restlessness, pacing, inability to settle. Dogs in the early phase look anxious — they pace, change position, lie down briefly then get up again. As the condition progresses they become weak, then collapse.
4. Excessive drooling. Hypersalivation reflects nausea and the inability to swallow normally. Often accompanied by repeated swallowing motions.

Late signs (suggesting serious progression): pale or grey gums, weak rapid pulse, collapse, laboured breathing.

What to do, in order

1. Confirm signs. 60 seconds. The three-question test above.
2. Phone the emergency clinic. Tell them you suspect GDV and the breed. They will prepare a decompression kit. If your usual vet is closed, find the nearest 24-hour facility — minutes matter.
3. Move the dog gently. Lift, do not let them jump. Carry to the car if necessary; large dogs need two people.
4. Drive directly. Avoid speed bumps, sharp turns. The stomach is fragile in this state.
5. Communicate during the drive. Keep the dog supported in a stable position; avoid stress, bright light, sudden noise.

Three things never to do

• Do not give anti-gas remedies, charcoal, or "burping" attempts. The cardia (entry to the stomach) is closed by the rotation. Gas cannot escape upward; medication cannot reach the stomach.
• Do not try to make the dog vomit. Inducing vomiting in a dog with GDV can rupture the stomach wall, which is now stretched and friable.
• Do not wait to see if it "passes." GDV does not resolve spontaneously. The longer the stomach remains rotated, the more tissue dies and the lower the survival probability.

What happens at the clinic

Treatment is sequential and time-critical:

1. IV access and shock-rate fluids. Two large-bore catheters; aggressive volume to support circulation.
2. Stomach decompression. Either by orogastric tube (if the rotation has not closed the cardia) or by trochar puncture through the abdominal wall. Air and stomach contents are released; the dog often visibly improves within minutes.
3. Imaging. A right-lateral radiograph confirms the rotation (the classic "double-bubble" or "Popeye sign").
4. Surgery. Once stable, the dog is taken to surgery to derotate the stomach, assess for tissue death (necrosis), and perform a gastropexy — surgically attaching the stomach wall to the abdominal wall to prevent recurrence. Without gastropexy, recurrence rate is around 80%; with it, <5%.

Realistic costs for a complete GDV case in India: ₹40,000–1,20,000 depending on city, complications, and ICU duration. UK: £3,000–6,000. US: $5,000–10,000. Pet insurance, where carried, typically covers most of this.

Prevention

You cannot eliminate risk in a high-risk breed, but you can reduce it substantially:

• Prophylactic gastropexy. The gold-standard prevention. Often performed at the time of neutering in high-risk breeds, increasingly available laparoscopically. Reduces GDV mortality dramatically and pays for itself across the dog’s lifetime if any GDV episode is averted.
• Feeding management. Two or three smaller meals rather than one large; avoid vigorous exercise within an hour of eating; do not allow rapid water consumption immediately before or after meals. The evidence for elevated bowls (once recommended) is now mixed; current AVMA guidance suggests they may slightly increase risk in some breeds.
• Stress management. Stress is a documented trigger; transitions, kennels, and competitive events warrant extra vigilance.
