Have you noticed your Great Dane acting restless or uncomfortable? If you see a change in behavior along with swelling of his abdomen, he may have bloat (also known as gastric torsion, twisted stomach, Gastric Dilatation-Volvulus (GDV). Bloat is a potentially life-threatening condition that can be caused by many factors, including increased fermentation in the gut secondary to a diet change, increased thoracic pressures, and abdominal disease. Large breed dogs such as Great Danes, Irish Wolfhounds as well as other deep-chested dogs are predisposed to it because of the additional space it creates in their abdomen. Great Danes commonly get bloat, and some research even shows that it occurs in over 42% of all Great Danes. [1] X Research source The stomach can swell or become twisted during several stages while your dog rapidly deteriorates. Be aware of the symptoms of bloat and get immediate veterinary help. This will give your dog the best chance of survival. [3] X Research source Canine gastric dilatation - volvulus syndrome in a veterinary critical care unit. Brockman. JAVMA 207 (4)
Steps
-
Look for swelling. Your dog's stomach may be swollen if it makes a tympanic, drum-like sound when you flick it. This means the stomach is full of gas. While swelling is the most obvious symptom of bloat, it can be difficult to spot in Great Danes because of their large size. If you're unsure whether your Great Dane has a swollen stomach, discuss your concerns with a veterinarian rather than wait for symptoms to improve. Early treatment of bloat can greatly increase chances of survival. [3] X Research source Increasing stomach pressure may lead to: [5] X Research source Small Animal Internal medicine. Nelson & Couto.

- Swelling
- Sealing of the stomach—the intestines wrap and twist above the stomach, impeding the flow of liquid and ingest out of the stomach
- Shutting down of blood supply to the stomach wall
- Decreased blood supply to major organs
- Organ failure
- Toxin buildup in the blood stream
- Shock from major swings in electrolytes and blood pressure
- Death from low blood pressure and toxin buildup
- For reference, a large breed dog such as a Great Dane typically has a resting heart rate of 60-80 bpm and a respiratory rate of 24-32 bpm.
-
Check your dog's mouth. Lift up your Great Dane's lips and look at his gums. They should be a healthy pink color and color should quickly return if you press the gums and release your finger. If you notice pale or ashen gums or the gums remain blanched white after you press them, your dog may have bloat.
- If your dog's gums are unusually dark red, blue, or white, get medical attention immediately. [6] X Research source

Pay attention to breathing and pulse. Your dog may have bloat if he has labored breathing that sounds heavy and rapid. It might sound like your dog is panting instead of breathing. If he has bloat, your Great Dane's pulse will also be rapid as though he just exercised. [7] X Research source
- Under normal conditions, a Great Dane's heart rate is around one beat per second. He should also breathe every two to three seconds during rest. [8] X Research source
-
Watch for drooling. Your Great Dane may drool heavily and have strings of saliva hanging from his mouth. This happens when the stomach is sealed off, leaving swallowed saliva nowhere to go. The Great Dane gives up swallowing and drools instead. [9] X Research source
- You may also notice your dog dry retching. If your dog has eaten recently, but is dry heaving contact a veterinarian immediately. This is a classic sign of bloat.
- The drooling is due to abdominal pain, nausea, and, most commonly, retching.
-
Consider your dog's body type. Dogs that are deep chested and narrow-bodied are at high risk of bloat. Because of their unique anatomy, Great Danes are at the highest risk of suffering from bloat. A Great Dane's large stomach is suspended in only two places within the abdomen, like a hammock. If the stomach is full of food and gas, it can become unstable and flip over on itself, especially if the Great Dane exercises or rolls after eating. [10] X Research source
- Other breeds that are at high risk for bloat include: German Shepherds, Irish Setters, Red Setters, St. Bernards, and Weimaraners.

Monitor your dog's behavior. Most noticeably, your Great Dane may be uncomfortable and unable to settle. He may also look anxious and frequently glance at his flanks, where you might notice swelling as air fills his stomach. As the bloat worsens, your dog may become increasingly distressed. He may whine or howl to vocalize his pain and discomfort. If untreated, he will go into shock and might collapse as his circulation system fails. [11] X Research source
- Bloat is usually associated with recently eating a meal. After eating, you may notice your Great Dane become restless and pace around.
-
Contact a veterinarian. If you suspect your dog has bloat, get veterinary attention immediately. Call or meet with the veterinarian to discuss your Great Dane's symptoms. Since early treatment is vital, it's better to be overly cautious and get medical attention as soon as you see signs of bloat.
- Even with veterinary care, around 25-33% of dogs with bloat die, so early treatment is important. [12] X Research source
-
Get a physical examination. The veterinarian will feel your dog's abdomen for signs of tympany (gas build up) and check for signs of shock. If bloat is suspected, the veterinarian might insert a large bore catheter into the stomach where there's the greatest buildup of gas. This will remove the immediate pressure. [13] X Research source
- Your Great Dane probably has bloat if foul smelling gas comes out through the catheter.
-
Get further testing. The veterinarian may want to confirm a diagnosis of bloat with additional testing. In one test, your Great Dane will lay on his side while an x-ray is taken of the front of his abdomen. The veterinarian may confirm bloat if the x-ray shows a stomach dilated with air and soft tissue running across it.
- The veterinarian may also order an ultrasound to look at the location of the spleen. However, it's more likely that the vet will want to begin relieving stomach pressure and corrective surgery instead.
