TL;DR: Bloat (GDV) is a critical, life-threatening emergency requiring immediate veterinary care if your dog shows signs of a distended abdomen or unproductive retching. Every minute is vital to prevent shock and organ failure.
What are the primary symptoms of dog bloat and GDV?
A rigid, distended abdomen combined with unproductive retching (dry heaving) are the classic signs of Gastric Dilatation-Volvulus (GDV), commonly known as bloat. This condition occurs when the stomach fills with gas and then twists on itself, cutting off blood supply to vital organs and trapping gas inside.
Is dog bloat a veterinary emergency that requires immediate action?
- Treat this as a critical, life-threatening emergency with a "High" urgency level.
- Every minute counts, as the twisting of the stomach can lead to shock, organ failure, and tissue death within a very short timeframe.
- Do not wait for symptoms to subside; transport your dog to the nearest 24-hour emergency veterinary hospital immediately.
How can a photo or video help the veterinary triage team prepare for my arrival?
- Take a quick photo or a 5-second video of your dog's abdomen and behavior, provided it does not delay your departure.
- Provide a visual to help the triage team assess the level of distension.
- Help the veterinary staff prepare necessary life-saving equipment and the surgical team before you even walk through the door.
Clinical Context (Merck Veterinary Manual)
Dogs presenting with gastric dilatation-volvulus (GDV) may have a history of nonproductive retching, hypersalivation, and restlessness. Acute or progressive abdominal distention may be noted, and the dog may be found recumbent and depressed with an enlarged, tympanic abdomen. Abdominal pain and/or splenomegaly may be appreciated on abdominal palpation. Progression to volvulus predisposes to hypovolemic shock, with associated signs including weak peripheral pulses, tachycardia, prolonged capillary refill time, pale mucous membranes, and dyspnea. An irregular heart rate and pulse deficits may indicate a cardiac arrhythmia. The expanding stomach may compress the thoracic cavity and inhibit diaphragmatic movement, leading to respiratory distress. Radiographs, specifically right lateral and dorsoventral recumbency, are essential to distinguish simple gastric dilation from GDV, revealing a distended, gas-filled gastric shadow with the pylorus located dorsal and cranial to the fundus on the right lateral view.
