After 30-60 minutes the dog begins to appear swollen in it's midsection due to the accumulation of gas in the stomach. The dog will begin to pant heavily and breathing becomes rapid and shallow. The gums become pale and the extremities cool. This closes both the esophagus and pylorus, preventing the dog from relieving the gas pressure. The condition is rapidly fatal, causing shock, coma and death within a very short time.
Diagnosis is relatively easy based on breed, history and clinical signs.
Your veterinarian may take x-rays to confirm the diagnosis. GVD is a true life-threatening emergency. If you suspect your dog may be showing signs, take your dog to your vet or emergency clinic without delay. Treatment is aimed at reducing the gas pressure and returning the stomach to its normal position. Your vet will remove pressure via a stomach tube or trochar through the stomach wall.
