Preventing Bloat (GDV) in Dogs — Calgary
Gastric Dilatation-Volvulus (GDV) — commonly called bloat — is one of the most rapidly fatal emergencies in veterinary medicine. The stomach fills with gas, then rotates on its axis, trapping that gas and cutting off blood supply to the stomach and spleen. Without emergency surgery, most dogs die within hours. Even with treatment, mortality is 10–30%. If your dog is a large, deep-chested breed, this is information you need before it happens.
Why This Matters
GDV kills dogs whose owners don't recognize the early signs. The early signs are not dramatic — they're subtle enough that owners often wait several hours before going to the vet, by which time the survival window has narrowed significantly. The non-productive retch — attempting to vomit with nothing coming up — is the critical early sign that most people don't know to look for. Knowing it can save your dog's life.
Key Facts
Predisposed breeds: Great Dane, German Shepherd, Standard Poodle, Doberman Pinscher, Weimaraner, Irish Setter, Rottweiler, Saint Bernard. The common factor is large size and a deep, narrow chest that allows the stomach room to rotate.
General veterinary emergency guidelines
Vigorous exercise within 1–2 hours of eating is a significant risk factor. Eating increases stomach volume; vigorous movement increases the likelihood of rotation. This is the most actionable prevention point.
General veterinary emergency guidelines
Fast eating — gulping food and swallowing air — increases stomach gas volume and GDV risk. Slow feeder bowls or puzzle feeders reduce eating speed meaningfully.
General veterinary emergency guidelines
Gastropexy — a surgical procedure that permanently tacks the stomach to the abdominal wall — prevents rotation entirely. Recommended prophylactically for highest-risk breeds, often done at the same time as spay or neuter.
General veterinary emergency guidelines
Mortality rate even with emergency surgery: 10–30%. Some studies show survival rates dropping below 50% when treatment is delayed beyond 6 hours from onset. Speed to the emergency vet is the single biggest factor in survival.

What Owners Should Do
Practical steps you can take right now.
- 1
If you have a large, deep-chested breed, talk to your vet about prophylactic gastropexy — it eliminates the risk of volvulus (the twist) entirely. Ask about doing it concurrently with spay or neuter.
- 2
Feed two smaller meals daily rather than one large meal. Smaller stomach volume after eating reduces GDV risk.
- 3
Wait 1–2 hours after feeding before vigorous activity — no off-leash running, no active play, no intense exercise.
- 4
Use a slow feeder bowl or puzzle feeder if your dog eats quickly. Reduced air swallowing during eating reduces gas accumulation.
- 5
Know the signs: non-productive retching, abdominal distension (the belly looks enlarged or tight), hypersalivation, restlessness, rapid deterioration.
- 6
At the first sign of non-productive retching combined with any abdominal swelling in a high-risk breed — drive to the emergency vet immediately. Do not call ahead. Do not wait to see if it resolves.
- 7
Inform your daycare about your dog's breed and feeding schedule — feeding before daycare affects how we manage their morning.
Warning Signs to Watch For
Know when something needs attention.
- Non-productive retching — the dog repeatedly attempts to vomit with nothing or almost nothing coming up. This is the most critical early sign.
- Abdominal distension — the belly appears noticeably larger, firm, or tight, often especially pronounced on the left side.
- Excessive drooling or hypersalivation — dogs in distress from GDV often drool significantly.
- Restlessness and inability to settle — the dog appears uncomfortable, pacing, or distressed.
- Rapid deterioration to pale gums, weakness, and collapse — late-stage shock.
Immediately. If you observe non-productive retching with any abdominal distension in a large, deep-chested breed, this is an emergency. Drive to Western Veterinary Specialist and Emergency Centre (52nd St SE, Calgary, 24/7) without delay. GDV does not resolve on its own and waiting kills dogs.
The PAWS Perspective
We have Great Danes, German Shepherds, Standard Poodles, and Weimaraners in our pack. We know who the GDV-risk dogs are before they arrive. For these dogs, we ask at drop-off what time they were fed and we manage their morning activity accordingly — no vigorous play in the first hour if they ate before arriving.
This is one reason we ask about feeding schedules at drop-off for large breeds. It's not administrative — it's management. If your Great Dane had a large breakfast at 7 AM and arrives at 8 AM, we know to keep them calm for the first hour. That's the kind of detail that matters.
"I've told owners of newly adopted Great Danes and Standard Poodles to ask their vet about gastropexy at the first appointment. Some have done it. I think it's the right call for those breeds. The surgery is not complex, done once, and eliminates the volvulus risk for life. The alternative is hoping you recognize non-productive retching at 11 PM on a Tuesday and drive fast enough."
— Eric Yeung, Owner, PAWS Dog Daycare
Gastropexy prevents the volvulus — the twist. It doesn't prevent gastric dilatation (the gas filling). A dog with a gastropexy can still bloat and still be uncomfortable, but the stomach can't twist and the emergency aspect is removed. Knowing the difference matters.
