There is no magical way to prevent a dog from vomiting. Prevention requires identification and removal of the underlying cause of the condition. Because there are so many diverse causes of vomiting, there is no one protocol to recommend. In general, dogs should not be exposed to potentially toxic substances. They also should have regular veterinary examinations to ensure their good health. High-quality nutrition and a healthy lifestyle, with moderate exercise, lots of fresh air, warm and comfortable housing and plenty of human companionship, are also important to maintaining the good health of our beloved canine companions.
Gastric dilatation volvulus , or gastric torsion and bloat, primarily affects breeds with deep, narrow chests, such as Great Danes , St. Bernards , German Shepherds , Standard Poodles and Irish Setters . The stomach twists on its supporting ligaments , sealing off the exits, and the contents begin to generate gas pressure which is very painful and rapidly causes shock and necrosis of large areas of stomach tissue. It can be fatal within a few hours. Dogs who have experienced bloat are very susceptible to recurrences. Treatment involves stabilization and abdominal surgery to tack the dog's stomach down to prevent recurrence ( gastropexy ).
