Dogs can die of bloat within several hours. Even with treatment, as many as 25-33% of dogs with GDV die. The gastric dilatation is one part of the condition and the volvulus or torsion is the second part. In bloat (dilatation), due to a number of different and sometimes unknown reasons, the stomach fills up with air and puts pressure on the other organs and diaphragm. The pressure on the diaphragm makes it difficult for the dog to breathe.
