Bloat and Torsion in Dogs:
The Signs That Mean Go Now

Three names for one emergency

Dog bloat, twisted stomach and stomach torsion all refer to the same thing: gastric dilatation-volvulus, or GDV. The stomach fills with gas (dilatation) and then twists on itself (volvulus), pinching off its own entrance and exit and cutting off the blood supply to the stomach and nearby organs. Left untreated it is fatal, and the clock starts the moment it happens.¹

A dog can bloat without the stomach twisting, but only an X-ray can tell the two apart. That is why the rule is simple: if you see the signs below, go to the vet or an emergency clinic first and ask your questions later. Do not wait and see.

The signs to know by heart

• A swollen bellyNot subtle. The belly is visibly distended with air and gas.
• Trying to vomit or belch, with nothing coming upThe dog is trying to release the pressure, but with GDV the way out is pinched shut.
• Shallow, fast pantingShort rapid breaths are a sign of distress.
• Restless, or won't movePacing and an inability to settle, or lying still and refusing to get up. Both mean pain.
• Pale gums and tongueA sign that blood flow has been disrupted.
• Drooling or a hunched stanceOften seen alongside the rest.²

Even if you only see one or two of these, go now. Once the stomach has twisted, every hour counts.

What the vet will do

Relieving the pressure comes first. The vet passes a tube down the esophagus if they can, or puts a needle into the stomach through the side. Once the gas is out, an X-ray shows whether the stomach has twisted. If it has, surgery is the only way to save the dog: the stomach is untwisted, any damaged tissue is removed, and the stomach is usually tacked to the body wall (a gastropexy) so it cannot twist again.¹

Treatment is not always successful. Even with care, somewhere between one in five and nearly half of treated dogs do not survive, and the odds get worse the longer the delay.¹ The vet will talk you through the risks and the recovery. Dogs that are stabilised and operated on early do best.³

Which dogs are most at risk

Large and giant breeds with deep, narrow chests. Great Danes, Doberman Pinschers, Weimaraners, Saint Bernards, the Setters, and others built the same way. Genetics are a proven factor: a deep, narrow chest, and a parent or sibling who bloated.¹ Risk rises with age, and with eating one large meal a day.⁴

The cause itself is still unknown. Researchers have studied everything from raised food bowls to stress and temperament.³ For a dog at high risk, some vets recommend a preventive gastropexy, often done at the time of spaying or neutering; ask yours whether it makes sense for your dog.¹

Start with what goes into the stomach

This condition begins in the stomach, so it's worth looking at what's being put there. Most commercial dog foods are heavy in fermentable carbohydrates: corn, rice, wheat. Dogs don't need those carbohydrates, and fermenting them produces extra gas during digestion, which is the last thing a bloat-prone dog needs. A lower-carbohydrate food naturally cuts down on that gas; our recommended foods guide shows what to look for.

Nutrition also builds the digestive system itself. The additives and preservatives in many kibbles can get in the way of the body absorbing whatever nutrition the food does contain. Good food that truly nourishes the whole body is the ounce of prevention here. And be honest with yourself about the limits: even when every good idea is in place, bloat can still happen. The point is to know the signs and act fast, especially if you own a bloat-prone breed.

Linda Arndt's Core 4

Linda Arndt, the canine nutritionist known as the Great Dane Lady, studied and advised on bloat for years, and we worked with her for a long time. For large breeds prone to bloat she recommended what she called the Core 4, as part of every diet:⁵

• A low-carbohydrate diet
• Live dietary enzymes (Nzymes Sprouted Granules)
• Probiotics and digestive enzymes (Nzymes Bac-Pak Plus)
• pH support (Nzymes Ox-E Drops)

Today those three products are how we still support a bloat-prone dog's digestion. None of them prevents bloat; what they do is give the gut live-food enzymes, beneficial bacteria and the means to break food down well, so there is less to ferment and less strain on the whole system.

Bac-Pak PlusFive live probiotic strains plus eight digestive enzymes, to break food down well and keep the gut's bacteria in balance. Ox-E DropsHighly alkaline, with a pH of 13: a few drops a day to support healthy pH and oxygen balance from within.
