"Food is thought to be a factor in bloat, the number one cause of premature death in Great Danes. Deep-chested breeds such as Great Danes can experience this condition, also called gastric dilatation and volvulus, in which the stomach distends then rotates, cutting off blood supply to various parts of the body as well as shutting down digestion. A dog can die within hours of this painful condition. Most cases need emergency surgery.|
"Although the cause of bloat is unknown, it is generally believed that feeding large breeds multiple small meals a day, while preventing vigorous exercise before and after eating or drinking large quantities of water, can help prevent bloat. Some breeders opt for a preventative surgery called a prophylactic gastropexy, or "preventative tack"" (Kim D.R. Dearth. "Great Dane." Dog World, May 2004: 26-35).
