Bloat, or gastric dilatation and volvulus (GDV), is a serious, life-threatening condition seen in dogs. GDV mainly affects large deep-chested dogs, but it can affect any size of dog. It happens when distention of the stomach with food and/or air together with the momentum of this now heavy organ by movement (walking or running) causes the stomach to “flip” upon itself, closing both the in-flow and out-flow passages. The stomach then becomes more and more distended, causing pressure on the large blood vessels of the abdomen, cardiac irregularities, difficulty breathing, tissue death and toxin release.
