Pocket VetBloat (GDV) in dogs
Bloat, or GDV, is when a dog's stomach fills with gas and twists, cutting off blood flow. It's one of the most time-critical emergencies in dogs.
What it is
The stomach distends with gas and rotates, trapping its contents and blocking blood supply. It progresses to shock within hours and is rapidly fatal without surgery. Deep-chested breeds (Great Danes, German Shepherds, Standard Poodles) are most at risk.
Symptoms
- ●Swollen, hard, distended belly
- ●Unproductive retching (trying to vomit, nothing comes up)
- ●Restlessness, pacing, unable to settle
- ●Drooling, pale gums, rapid breathing
🔴 When to act now
- ●ALL suspected bloat is an emergency — go to a vet immediately
- ●Do not wait; survival depends on minutes to a few hours
Treatment & management
Bloat requires immediate emergency surgery to untwist the stomach and tack it in place. Preventive surgery (gastropexy) is often recommended for high-risk breeds. Feeding smaller meals and avoiding hard exercise right after eating may reduce risk.
