One traditional preventative has been to raise the height of food and water bowls, but this was found to actually increase risk by 110 percent. This correlation of risk was verifiable; the dogs of the breeders in this study did not have close relatives that had experienced bloat.

Several diet-related factors were associated with a higher incidence of bloat. These include feeding only dry food, or feeding a single large daily meal. Dogs fed dry foods containing fat among the first four ingredients had a 170 percent higher risk for developing bloat. Dogs fed dry foods containing citric acid and were moistened prior to feeding had a 320 percent higher risk for developing bloat.

Conversely, feeding a dry food containing a rendered meat-and-bone meal decreased risk by 53 percent in comparison with the overall risk for the dogs in the study. Mixing table food or canned food into dry food also decreased the risk of bloat.

During the past 30 years there has been a 1,500 percent increase in the incidence of bloat, and this has coincided with the increased feeding of dry dog foods. There is a much lower incidence of bloat in susceptible breeds in Australia and New Zealand. Feeding practices in these countries have been found to be less dependent on dry foods.

From the research performed to date, we can list several factors that, added together, can characterize the typical dog that develops bloat: a deep and narrow chest; leanness; a relative that has had a bloat episode; eating quickly; a dry-food diet; a single, large daily meal; stress; and a fearful, nervous, or aggressive temperament.
