There's good reason why veterinarians call bloat "the mother of all emergencies.
Symptoms of bloat, which is incredibly painful for the dog, include pacing and restlessness; a distended abdomen; turning to look at or bite at the flank area; rapid, shallow breathing; retching without actually vomiting up any food, and excessive drooling.
Bloat is a two-part disorder, telegraphed by its formal name: gastric dilatation and volvulus.
This was precisely the scenario that the quick-thinking Greyhound handler had sought to avoid: By inserting the bloat tube down the esophagus and into the stomach, she not only created an avenue of escape for the trapped stomach gases, but also ensured that the stomach could not twist while the tube was inserted.
You've had a busy day at work, you rush home to eat and your stomach bloats out uncomfortably.
If you really can't ditch your bean fix, try pureeing or mashing them for minimal bloat - the body can digest purees better than chunks of high-gas foods.
It's easier to beat the bloat if you choose foods that encourage you to pass water.
