What Is Gastric Dilatation-Volvulus?
Gastric Dilatation-Volvulus (GDV), often called bloat, occurs when the stomach rapidly fills with gas and then twists, trapping the gas inside. This twisting blocks blood flow, causes the stomach to expand, and quickly leads to shock.
GDV is one of the most serious and life-threatening emergencies a dog can experience. It can progress within minutes, cutting off blood supply to vital organs, and is fatal without immediate treatment.
🚨Signs of Bloat to Watch For:
If you see ANY of these signs, seek emergency veterinary care immediately:
• Sudden, severe abdominal swelling
• Unproductive retching (trying to vomit but nothing comes out)
• Restlessness, pacing, or inability to settle
• Excessive drooling
• Panting or signs of distress
• Weakness or collapse
• Pale gums
Dogs may show only one of these signs... When in doubt, call your veterinary hospital or an emergency veterinary facility.
When the stomach fills rapidly with gas and twists, it cuts off circulation to the stomach, spleen, and heart. The severe buildup of gas creates extreme pain and dangerous internal pressure, while shock can develop within a very short period of time. Because GDV progresses rapidly, a dog’s chance of survival depends heavily on receiving immediate veterinary care. Even with emergency surgery, GDV can still be fatal if intervention is not provided quickly.
Without treatment, GDV has a mortality rate close to 100%. With fast emergency care, many dogs survive.
🐶 Which Dogs Are at Higher Risk?
While GDV can happen to ANY dog, these factors increase risk:
• Large, deep-chested breeds (e.g., Great Danes, Standard Poodles, Shepherds, Bernese Mountain Dog, etc.)
• Eating or drinking too quickly
• Family history of bloat
• Older age
GDV strikes fast, progresses fast, and requires IMMEDIATE emergency care. Knowing the signs and acting fast can save your dog’s life. If you ever suspect bloat/GDV, don’t wait. Call your emergency vet.
