Bloat (GDV) in Great Danes
Also known as: GDV
Great Danes have the highest lifetime risk of GDV (Gastric Dilatation-Volvulus, aka bloat) of any breed — some studies put it at over 40% lifetime risk. GDV is a true emergency where the stomach fills with gas and twists on itself, cutting off blood supply. Without immediate surgery, it is rapidly fatal.
Why Great Danes are predisposed to bloat (gdv)
The Great Dane's chest is extraordinarily tall and narrow — the deepest chest-to-width ratio of any breed — which is the single biggest anatomical risk factor for stomach volvulus. Add age (>2 years), large meal size, fast eating, anxious temperament, and a first-degree relative that had GDV, and you have the breed with the highest risk of any. Many Great Dane breeders and vets recommend prophylactic gastropexy at the time of spay/neuter.
What you'll see at home
- Unproductive retching — trying to vomit, nothing coming up (hallmark sign)
- Visibly distended, drum-tight abdomen
- Restlessness, pacing, can't get comfortable
- Excessive drooling
- Anxious panting and weakness
- Pale gums, fast heart rate (shock)
- Standing with elbows out, neck extended
- Collapse (late sign — shock is well established)
Red flags — go to an emergency vet
- ⚠ All of it is urgent — every symptom listed is an emergency-vet-NOW situation
- ⚠ Unproductive retching plus distended abdomen = drive to ER immediately
- ⚠ Do not call telehealth, do not wait, do not 'see if it resolves'
- ⚠ GDV kills in hours; in Great Danes, sometimes faster
How vets diagnose bloat (gdv)
An emergency vet diagnoses GDV with physical exam (distended abdomen, shock signs) and an abdominal radiograph showing the characteristic 'double-bubble' or 'reverse C' shape of a twisted stomach. Diagnosis and surgical decision happen within minutes of ER arrival.
Treatment options
Emergency stabilization (IV fluids, decompression by gastric tube or trocar) and immediate surgery. The surgeon untwists the stomach, removes any dead tissue, and performs a gastropexy (tacks the stomach to the abdominal wall to prevent recurrence). Recurrence without gastropexy is high; with gastropexy, near-zero.
Common medications for this condition
Don't start, stop, or change any of these medications without a licensed vet's guidance.
Living with a Great Dane who has bloat (gdv)
- 1 PROPHYLACTIC GASTROPEXY is strongly recommended for Great Danes — done laparoscopically at the time of spay/neuter, it nearly eliminates GDV risk
- 2 Feed 2-3 smaller meals/day, never one giant meal
- 3 Slow-feed bowls or food puzzles for fast eaters
- 4 Do NOT use elevated food bowls — evidence now associates them with HIGHER GDV risk
- 5 Wait 1 hour after eating before vigorous exercise
- 6 Manage anxiety — anxious dogs have higher GDV rates
- 7 Know your nearest 24/7 ER — keep address and phone on the fridge
- 8 Train every member of the household to recognize unproductive retching = drive now
Can RexVet help with this online?
RexVet is the right place to discuss prophylactic gastropexy planning, feeding and weight management for Great Danes, anxiety medications for at-risk dogs, post-op recovery questions, and walking through warning signs so the whole family is prepared. We can also help you find a board-certified surgeon for laparoscopic gastropexy.

Prognosis — what to expect
Highly time-dependent. Survival rates above 80% when surgery happens within a few hours of symptom onset, drops sharply with delay. Great Danes that survive GDV with gastropexy typically don't have a recurrence and can live full normal lives. The single biggest determinant is how quickly the dog gets to surgery — minutes matter.
Frequently asked questions
Frequently asked questions
Should I get prophylactic gastropexy for my Great Dane?
Strongly yes — Great Danes have the highest GDV risk of any breed (40%+ lifetime in some studies), and prophylactic gastropexy nearly eliminates that risk. It's often done laparoscopically at the time of spay/neuter, which is the most cost-effective and least invasive moment. Talk to your vet about this before your Great Dane is 1 year old.
What does bloat look like in a Great Dane?
Unproductive retching (trying to vomit, nothing coming up), a visibly distended drum-tight belly, restlessness and pacing, excessive drooling, anxious panting, and an inability to settle. The dog often stands with elbows out and neck extended. If you see this in a Great Dane, drive to an emergency vet immediately.
How can I prevent bloat in my Great Dane?
The single most effective intervention is prophylactic gastropexy. Lifestyle: feed 2-3 smaller meals per day, use a slow-feed bowl, do not use elevated food bowls (current evidence is they increase risk), wait an hour after eating before exercise, and manage anxiety. These reduce risk but don't eliminate it the way surgery does.
Is bloat hereditary in Great Danes?
Genetics plays a role — dogs with a first-degree relative (parent, sibling) that had GDV have markedly higher risk. The breed-specific chest conformation is itself the inherited trait that creates the mechanical setup for stomach volvulus. If you know a relative had GDV, that's an even stronger argument for prophylactic gastropexy.
