Canine bloat, or gastric dilatation-volvulus (GDV), is the number-one cause of death for several large and giant breeds of dogs. It is a life-threatening disorder and if left untreated, can result in death.

Bloat occurs when the stomach fills with food, water and/or gas. This results in increased pressure that enlarges and compresses the stomach, and eventually causes the stomach to rotate or twist into an abnormal position.

When the stomach twists, it actually clamps off the inflow and outflow of the stomach’s contents, and the blood which passes to and from the stomach to keep the tissues alive and pass nutrients.

When the blood supply to the organ is cut off, the organ starts to die, and it can cause a cascade of events that will eventually lead to death if the dog does not get help in time.
Approximately 30 percent of dogs that develop bloat die, or have to be euthanized.

Common signs of “bloat” include excessive drooling, and the motions of vomiting but with nothing coming out.

Be especially vigilant about your dog’s diet, to stop gassiness, and especially in summer, whether their drooling is heat-related, or something more sinister.

Breeds at most risk include breeds with deep narrow chests and large or giant breed dogs such as the Akita, bloodhound, collie, Great Dane, Irish setter, Irish wolfhound, Newfoundland, rottweiler, Saint Bernard, standard poodle and Weimaraner.

If you have a large or giant breed dog, make sure that you are familiar with the risks and signs of bloat. Any change in a dog’s attitude and mood, or unexplained eating, drinking or bowel habits (that is, not caused by, say, a change in food or lifestyle) are usually a sign that something is going on that needs to be investigate. Early identification and prompt treatment of bloat is essential, and can save your dog’s life. Beware of Bloat, and help protect your large breed dog.
