Monitoring and Follow-up

Monitoring your dog’s symptoms and scheduling regular follow-up appointments with your veterinarian are essential steps in managing BVS effectively. Long-term management of BVS requires dedication and attention to detail. Here are some key aspects to focus on:

  • Regular Monitoring: Keep a journal to track your dog’s symptoms, including the frequency and nature of vomiting episodes. Note any changes in behavior or appetite.
  • Symptom Tracking: Record any new symptoms that may arise, such as lethargy or diarrhea, as they could indicate a need for adjustments in the treatment plan.
  • Dietary Adjustments: Work closely with your veterinarian to make necessary changes to your dog’s diet. This may involve feeding smaller, more frequent meals or switching to a specialized diet for sensitive stomachs.
  • Follow-up Appointments: Schedule regular check-ups with your vet to assess your dog’s progress and make any needed modifications to the treatment regimen.
  • Communication: Keep an open line of communication with your veterinarian regarding any concerns or developments in your dog’s condition.

Surgical Options for Severe Cases

In cases of BVS that are severe and unresponsive to conventional treatments, exploring surgical options may be necessary to provide relief for your dog. One such surgical option is laparoscopic gastropexy, a minimally invasive procedure where the stomach is surgically attached to the abdominal wall to prevent it from moving abnormally. This procedure can help alleviate the symptoms of BVS and reduce the likelihood of gastric torsion, a severe complication associated with the syndrome.

Post-operative care is critical after undergoing laparoscopic gastropexy. Your veterinarian will provide instructions on how to care for your dog during the recovery period, including monitoring for any signs of complications such as infection or incisional hernias. It’s essential to follow these guidelines diligently to ensure a smooth recovery process for your furry companion.

In the event of any complications post-surgery, immediate management is important. Contact your veterinarian immediately if you notice any abnormal symptoms or behaviors in your dog. By closely monitoring your pet and addressing any issues promptly, you can help ensure the best possible outcome following surgical intervention for severe cases of BVS.


By understanding the triggers for BVS and implementing dietary changes or medications as advised by a veterinarian, you can help minimize episodes and maintain your dog’s health. Regular vet check-ups are essential to monitor the condition and adjust treatment as needed to ensure your dog remains comfortable and healthy.
