GDV stands for Gastric Dilatation and Volvulus, which is a life-threatening disorder that primarily affects large and deep-chested dogs, although any dog may be affected. It occurs when the stomach fills with gas, food, or fluid and subsequently twists around itself, causing severe and life-threatening symptoms. The exact cause of GDV is still unknown, but several factors are likely to be involved, including genetic predisposition, being deep-chested, having a lean body condition, eating quickly, eating from a raised food bowl, and being fearful or nervous.

Symptoms of GDV tend to start very suddenly and get worse quickly. Dogs are at more risk after they have eaten or drunk a lot, especially if they exercise straight afterward. Immediate veterinary attention (within minutes to a few hours) is required to save the dogs life. Treatment for GDV should be sought out as soon as possible to increase the dogs chance of survival. The severity of the case determines the treatment recommendation for the affected dog. Treatment is likely to involve X-rays/scans, a fluid drip, pain relief, and surgery.

Statistically, large, deep-chested breeds are more prone to GDV. Predisposed breeds include Great Danes, Saint Bernards, Weimaraners, Irish Setters, Gordon Setters, Standard Poodles, Basset Hounds, Doberman Pinschers, and Old English Sheepdogs. However, any dog can bloat, even Dachshunds and Chihuahuas. Pet owners should be familiar with their nearest veterinary emergency facility in the event that their regular veterinarian is not available after hours or does not have experience handling this condition. If possible, call ahead and tell them you suspect bloat. Time is of the essence when dealing with cases of bloat, and the sooner your pet receives veterinary care, the better chance of a full recovery.
