Veterinarian Arthur Jankowski explains the difference between bloat -- also known as gastric dilatation -- and gastric dilatation-volvulus in dogs. The former involves distension of the stomach with gas, fluid or food, resulting in pain and a compromised blood supply. However, in dogs with GDV, the stomach is distended but also rotated, resulting in the occlusion of the gastrointestinal tract. This can quickly become life-threatening, and immediate veterinary intervention is needed.
