Great Dane: what research reveals about bloat and feeding-related risk factors
A Great Dane that gulps down its food in seconds from a raised bowl isn't just showing enthusiasm: for this breed, feeding habits are among the best-documented risk factors for gastric dilatation-volvulus, a life-threatening emergency that can turn fatal within hours.

What a landmark US study shows
A study by Glickman, Glickman, Schellenberg, Raghavan and Lee, published in 2000 in the Journal of the American Veterinary Medical Association, followed more than 1,600 large- and giant-breed dogs to identify non-dietary risk factors for bloat (study on Google Scholar). The Great Dane, the most represented breed in the study, carried an estimated lifetime bloat risk above 40%. Notably, the authors found that a raised feeding bowl and fast eating speed were both linked to higher risk, contradicting long-standing advice.
The risk factors identified
- A raised feeding bowl, long recommended for large breeds, which this study and the research that followed instead flag as a risk factor.
- Fast eating speed, particularly when tied to one large daily meal rather than several smaller portions spread through the day.
- A direct family history, since having a first-degree relative with a prior bloat episode meaningfully raises a dog's own risk.
Adapting daily meals
Splitting the daily ration into two or three meals rather than one, placing the bowl on the ground rather than on a raised stand, and avoiding intense exercise for an hour after eating remain the most commonly cited ways to reduce risk; our guide on raised dog bowls breaks down what the research actually shows.

Frequently asked questions
Should Great Danes avoid raised feeding bowls?
Available evidence suggests a bowl on the ground is the more cautious choice for this breed, despite the opposite advice that circulated for years.
How many meals a day help reduce the risk?
Two to three moderate meals rather than one large one are generally recommended for giant breeds predisposed to bloat.
Is bloat always fatal?
No, but it is an absolute emergency: prompt surgery is essential and greatly improves the outcome.
