Bloat and GDV in dogs: warning signs and emergency treatment
What to do now
Repeated unsuccessful attempts to vomit, sudden abdominal swelling, distress or restlessness can indicate GDV, a life-threatening emergency. Call an emergency vet and leave for assessment immediately. Do not wait for collapse or for the belly to become visibly large: swelling may be hidden under the ribs. A little foam does not make repeated retching safe.
Keep handling calm, restrict unnecessary movement and follow transport advice. Do not offer a meal, force water, give home remedies or try to release gas yourself.

Veterinary help in your selected country
Phone your usual vet; their recorded message should explain out-of-hours arrangements. If unavailable, contact a local emergency veterinary hospital. Confirm that it can receive your dog before travelling if possible; do not delay urgent care. Human emergency numbers are not veterinary helplines.
Open country-specific veterinary contactsUnderstanding the signs
Gastric dilatation means the stomach expands, often with gas. Volvulus means it twists. An enlarged, twisted stomach can obstruct blood return to the heart and damage its own blood supply, causing shock and tissue injury. Simple stomach enlargement and GDV cannot reliably be distinguished at home. The dog may pace, repeatedly change position, drool, look at the abdomen or stretch before becoming weak.
Painful abdominal swelling has other serious causes too; this guide cannot establish which is present.
Possible causes
Large, deep-chested and older dogs, and dogs with affected close relatives, have increased risk, but other dogs can develop GDV. Feeding and inherited factors may contribute; it is not explained by one food or one owner mistake. Retching can also occur with other digestive or airway problems, but repeated dry retching with distress warrants emergency assessment rather than testing explanations at home.
Safe practical steps
Phone ahead so the clinic can prepare and confirm the correct emergency destination. If possible, ask another person to drive while you watch the dog without restricting breathing. Support a weak dog gently and avoid pressing the abdomen. Note when signs began and the timing of the last meal, but do not delay to collect measurements or complete a questionnaire.
Do not walk the dog to move gas, massage the belly, insert anything into the mouth or stomach, or give anti-gas products instead of emergency treatment. Only veterinary equipment and trained staff can safely decompress the stomach.
What the vet may do
The team may stabilise circulation with intravenous fluids, oxygen and pain relief before or alongside diagnosis. Abdominal X-rays can identify the enlarged and twisted stomach; blood tests and ECG monitoring help assess shock and complications. The vet may release gas using a tube or another clinical technique. Confirmed GDV generally needs surgery to untwist and assess the stomach; damaged tissue or the spleen may need removal.
A gastropexy attaches the stomach to the body wall to reduce future twisting. Treatment carries risk and cannot guarantee recovery, even when started quickly.
Recovery, recurrence and prevention
Hospital monitoring may be needed for abnormal heart rhythms, organ injury and other consequences of shock. At home follow the individual feeding, medicine, wound and activity instructions, with early reassessment for renewed retching, swelling, weakness or breathing changes. Gastropexy reduces twisting risk but does not prevent all stomach enlargement. Discuss preventive gastropexy for a high-risk dog with your vet.
Smaller divided meals and sensible meal routines may form part of an individual plan; no routine fully removes risk, so knowing the signs remains essential.
Common questions
Can GDV happen without an obvious swollen belly?
Yes. The stomach may be largely beneath the ribcage; do not wait for visible swelling.
Does producing foam rule it out?
No. Repeated attempts producing only foam can still be an emergency.
Can I treat trapped gas at home?
Not when GDV is possible. Remedies or belly massage can delay essential treatment.
Does gastropexy prevent every future problem?
It reduces twisting risk, but enlargement and other emergencies remain possible.
