  3. The abdomen has become progressively distended and the dog appears uncomfortable and is pacing.
  4. On examination the dog is tachycardic with pale mucous membranes and a markedly tympanic cranial abdomen.
  5. Abdominal radiographs reveal a severely gas-distended stomach with compartmentalisation producing a classic double-bubble appearance.
  6. This condition occurs when the gas-filled stomach rotates around its axis, obstructing gastric outflow and rapidly compromising venous return.

Diagnosis

Gastric Dilatation Volvulus

Gastric dilatation-volvulus is an acute life-threatening condition most commonly affecting large deep-chested dogs. Gastric dilation followed by volvulus obstructs venous return and rapidly leads to shock without urgent treatment.
