Gastric torsion in dogs (bloat / GDV)
Gastric dilatation-volvulus (bloat, or stomach torsion, GDV) happens when the stomach fills with gas and twists on itself, cutting off the blood supply to the stomach and other organs. It is one of the most serious emergencies in dogs: without fast veterinary care it can be fatal within a few hours.
Why it is so serious
When it twists, the stomach is sealed at both ends: gas cannot escape and it swells, compressing large veins and cutting off blood flow. Shock sets in, along with damage to the spleen and the stomach wall and heart-rhythm disturbances. That is why there is no home first aid: the only treatment is urgent veterinary care.
Dogs at higher risk
It mainly affects large, deep-chested breeds, especially if they eat a lot at once, gulp a lot of water or exercise right after eating.
| Higher risk | Factors that increase it |
|---|---|
| Great Dane, German shepherd, Doberman | Eating one big meal a day |
| Boxer, setter, Weimaraner | Intense exercise just before/after eating |
| St Bernard, large mountain breeds | Eating or drinking very fast |
| Older, narrow and deep-chested dogs | Stress, family history |
Warning signs
- Swollen, tense abdomen (like a drum), sometimes behind the ribs.
- Unproductive retching: tries to vomit without success or only brings up drool.
- Restlessness, can't settle, whining.
- Excessive drooling, panting.
- Weakness, pale gums, collapse (signs of shock).
What to do step by step
- Go to the vet immediately. There is no home first aid: every minute counts.
- Call on the way so they can prepare emergency care.
- Move the dog carefully, without giving it water or food.
- Don't try to make it vomit or press on its abdomen.
What the vet will do
First they stabilise the shock with fluid therapy and decompress the stomach (with a tube or by releasing the gas with a needle). Urgent surgery is almost always needed to reposition the stomach and, in the same operation, fix it to the abdominal wall (gastropexy) so it cannot twist again. The sooner you arrive, the better the outlook.
How to prevent it
- Split food into 2–3 meals a day instead of one large one.
- Avoid intense exercise in the hour before and after eating.
- Don't let it gulp large amounts of water after exercise.
- In at-risk breeds, ask about preventive gastropexy (sometimes done during neutering).
Frequently asked questions
Can I do anything at home?
No. Gastric torsion needs urgent veterinary treatment (decompression and almost always surgery). The only useful thing is to go immediately; any delay worsens the outlook.
How do I tell it apart from simple indigestion?
A swollen, tense abdomen together with retching without vomit, drooling and restlessness is very suspicious of torsion. When in doubt, treat it as an emergency and go to the vet.
Does it happen to small dogs or cats?
It is very rare. Gastric torsion mainly affects large, deep-chested dogs; in small dogs and cats it is exceptional.
Does gastropexy remove the risk completely?
It greatly reduces the chance of the stomach twisting again, though it does not fully eliminate dilation. It is often recommended in high-risk breeds; discuss it with your vet.
Does a raised bowl help or harm?
The evidence is mixed and in some breeds it has been linked to higher risk. It is better to focus on splitting meals and avoiding exercise around mealtimes, and to discuss your case with the vet.
Can it happen again?
Without gastropexy, the risk of recurrence is high. That is why the stomach is usually fixed in place during surgery to prevent further torsion.
