A definitive understanding of the etiopatho genesis of canine gastric dilatation-volvulus, also known as bloat, remains elusive. While commercial dry dog foods have been theorized as a causative factor, there is little evidence that the form or composition of food has a major influence on risk. Feeding the at-risk dog multiple times per day may have some preventive effect, but prophylactic gastropexy is likely to be most effective in managing risk.
