THE QUICK ANSWER
No study shows that raised bowls prevent bloat. The one prospective study that examined bowl height, which followed 1,637 large and giant breed dogs, attributed about 20% of bloat cases in large breeds and 52% in giant breeds to a raised feeding bowl; a later owner survey did not find the link. For large, deep-chested dogs the cautious default is a bowl on the floor unless a veterinarian advises otherwise.

What bloat is, and why the bowl matters
Gastric dilatation-volvulus (GDV), usually called bloat, is an emergency in which the stomach fills with gas and can twist. The American College of Veterinary Surgeons reports mortality of about 15%, and notes that many veterinary surgeons now recommend a preventive gastropexy for at-risk breeds. For years, owners of large dogs were told to raise the food bowl to prevent bloat. That advice spread before anyone had tested it.
The study behind the warning
Researchers at Purdue University recruited 1,637 dogs from 11 large and giant breeds, among them Great Danes, Irish Wolfhounds, Akitas, Weimaraners and Standard Poodles, and followed them for a median of 2.4 years. Six percent developed GDV. Four factors were significantly linked to higher risk: increasing age, a first-degree relative with GDV, eating faster, and a raised feeding bowl. In the authors’ adjusted model a raised bowl roughly doubled the risk, and about 20% of cases in large breeds and 52% in giant breeds were attributed to it.
The study that did not find it
A 2012 University of Pennsylvania internet survey of 2,551 dogs did not find raised bowls among the factors significantly associated with GDV. Its data came from owners who volunteered, not from dogs followed forward in time. A 2017 evidence review for RCVS Knowledge weighed the two studies and concluded that the safest option, until there is more evidence, is to advise owners of at-risk dogs to feed from the floor: that may not reduce the risk, but nothing suggests it increases it.
What neither study proves
Both studies are observational, so they show association, not cause. Owners who already considered their dog at risk may have raised the bowl because of that risk. The Purdue dogs were show dogs from 11 breeds, and bowl height was recorded once, at the start. What the evidence does support is narrower and firmer: no study shows that a raised bowl prevents bloat.
What a feeder stand should and should not claim
For a private-label brand the claim matters more than the stand. Do not state or imply that an elevated feeder prevents bloat, reduces the risk of GDV or aids digestion. Publish the bowl-rim height for every size, and consider an adjustable design with a floor-level setting. If the stand is sold for comfort, for senior dogs or dogs with limited mobility, say exactly that, and advise owners of large, deep-chested breeds to ask their veterinarian. Slow feeders need the same care: faster eating was a risk factor in the Purdue study, but no study shows a slow feeder prevents GDV.
