Early recognition of this life threatening condition is vital.
Bloat is a life-threatening condition in which the stomach fills with air (dilatation) and/or twists upon itself (volvulus). It’s also called GDV - gastric dilatation volvulus.
Classically, the bloated dog has recently eaten a large meal and exercised heavily shortly thereafter.
Signs of bloat include:
Not every dog will have a classic appearance and some dogs will not have obvious abdominal distension because of their body configuration. If you are not sure, it is best to err on the side of caution and rush your dog to the veterinarian immediately.
What NOT to Do
We usually do not know why a given dog bloats on an individual basis. No specific diet or dietary ingredient has been proven to be associated with bloat. Some factors found to increase and decrease the risk of bloat are listed below:
Factors Increasing the Risk Of Bloat
Factors Decreasing the Risk Of Bloat
Contrary to popular belief, cereal ingredients such as soy,wheat, or corn in the first four ingredients of the ingredient list do not increase the risk of bloat.
Some breeds have a higher risk of bloat, such as Great Dane, Standard Poodle, Huntaways, Weimaraner, German shepherd, (as well as other deep chested dogs). A preventive surgery called a prophylactic gastropexy can often be performed when the dog is being spayed or neutered. This involves surgically attaching the stomach to the inside of the abdomen to prevent rotation. Ask your veterinarian for details and advice if you would like to discuss preventive surgery for bloat. Still, any dog can bloat even Dachshund and Chihuahua. We recommend not breeding animals with a history of GDV in their lineage as this may potentially decrease the risk of GDV for the animal and future generations.
When a suspected dog arrives in the clinic your dog will have a clinical examination and next most likely a radiograph (x-ray) to determine what has happened. The image will shows the enormously distended stomach nearly upside down and shows what is often called the "double bubble" sign where the stomach is divided into two gas-filled sections suggesting the twist (volvulus).
At that time several things need to happen quickly, your dog will need to be put on to IV fluids for shock, the stomach needs to be decompressed. The huge stomach is by now pressing on the major blood vessels carrying blood back to the heart. This stops normal circulation and sends the dog into shock. Making matters worse, the stomach tissue is dying because it is stretched too tightly to allow blood circulation through it. Medication is also given for pain, electrolyte imbalance and shock.
Once your dog is stable then we can proceed to surgery. This is not always straight forward and results will depend on tissue damage and whether the spleen is involved.
It is crucially important that the owners of big dogs be aware of this condition and prepared for it. Know where to take your dog during overnight or Sunday hours for emergency care. Avoid exercising your dog after a large meal. Know what to watch for. Enjoy the special friendship a large dog provides but at the same time be aware of the large dog's special needs and concerns.
