GDV stands for Gastric Dilatation-Volvulus Complex in clinical veterinary terminology. It is commonly referred to as "bloat".

This is a serious, life-threatening emergency of large, deep-chested dogs. The stomach fills with gas and fluid and is unable to empty. The stomach can twist, causing outflow into small intestine and eructation, or burping, to be obstructed further. Blood vessels are also occluded, causing cell death to the stomach and intestines, leading to necrosis (dead tissue) and possible rupture, shock, and blood sepsis (toxins released in the blood).

It is thought that the stomach dilates prior to twisting. A history of a large meal, exercise, and failed attempts to vomit (dry heaves) is common, but not always the case. Other potential causes of bloat are; cancer, reduced size in pyloric opening (the opening between the stomach and small intestine), or stomach foreign body (stone, sock, etc.).

Signs typically seen with GDV are: pain/restlessness, attempting to vomit, but not productive, excessive salivation (drooling), and abdominal enlargement. This condition is a medical emergency, and if this is suspected in your dog, please call a veterinarian immediately for treatment. Minutes count.
