Gastric torsion in Dogs: Recognizing Symptoms & Taking Immediate Action

What is a twisted stomach?

Gastric torsion in dogs (medical term: torsio ventriculi; English: gastric dilatation-volvulus, GDV) is an acute, life-threatening emergency. The stomach fills with gas or fluid and twists around its longitudinal axis—this interrupts the blood supply to the stomach tissue and simultaneously blocks the inflow and outflow of contents. Pressure in the abdominal cavity rises to critical levels within minutes, blood flow to adjacent organs is compromised, and the dog goes into life-threatening shock.

Without immediate emergency veterinary care and surgery, most affected dogs will not survive. Every minute counts. Along with poisoning and heatstroke, gastric torsion is one of the most serious and time-sensitive emergencies in small animal medicine.

Background + Scientific Context

Gastric torsion occurs most frequently in large and giant breeds with deep, narrow chests. A long-term study by Glickman et al. (2000, JAVMA) involving over 1,600 dogs identified several independent risk factors: older age, family history (first-degree relatives with a history of GDV), rapid Eat, and—contrary to popular belief—a raised food bowl as a risk factor rather than a protective measure. A retrospective analysis of 736 cases (Ward et al., 2020) confirmed that the survival rate for dogs undergoing timely surgery is 81–89%. The most important prognostic factor is the time window between symptom onset and surgical intervention.

According to Glickman et al., breeds at particularly high risk include: Great Dane (lifetime risk of GDV approximately 36.7%), Irish Wolfhound, Gordon Setter, Weimaraner, Doberman, Leonberger, Bernese Mountain Dog, and Rottweiler. In small, deep-chested breeds (e.g., Dachshund, Basset Hound), gastric torsion is less common but not impossible.

Prophylactic gastropexy—the surgical fixation of the stomach to the abdominal wall—reduces the lifetime risk of GDV to less than 0.3% and the risk of recurrence after a previous episode of GDV to less than 5%. For highly predisposed breeds, preventive gastropexy (which can be performed laparoscopically) is a serious option that should be considered on a case-by-case basis by a veterinarian.

Vitomalia-Position

Stomach torsion is a medical emergency—it’s not a condition to monitor, and it’s not a situation where home remedies or waiting it out will work. We recommend that owners of large and giant breeds familiarize themselves with their local emergency veterinary clinic in advance: its address, phone number, and hours of operation. Regular clinics are often closed in the evenings and on weekends—knowing where to find a veterinary hospital with 24-hour emergency services can save a life.

The debate over elevated food bowls has not been conclusively resolved by science. An individual’s risk profile (breed, age, family history, eating speed) remains more relevant than individual factors. We reject the recommendation of raised food bowls as a means of preventing GDV without an evidence base. For dogs that eat quickly, snuffle mats or slow-feeder bowls are sensible options.

When does gastric torsion become a concern?

A twisted stomach can occur at any time, but it is more common after large meals, after intense physical activity, immediately after Eat, or during periods of stress. A typical scenario is an emergency in the evening after the main meal.

Extra caution is advised in the following situations:

• Owners of large and giant breeds with deep chests
• Dogs with a family history of the condition (parents or siblings with a history of GDV)
• Older dogs of large breeds (the risk increases with age)
• Dogs that eat quickly and greedily
• Dogs that have just had abdominal surgery (require extra care for the first 24–48 hours)
• During the hot summer months, when dogs are at increased risk of heatstroke

Practical application

Symptoms that require immediate action:

• A bloated, tense, and tender abdomen—often visible from the side
• Unsuccessful retching (retching without vomiting)
• Severe restlessness, whining, inability to lie still
• Excessive salivation
• Weakness, circulatory collapse, pale-white or bluish mucous membranes — signs of shock
• Difficulty breathing caused by pressure from the distended stomach on the diaphragm

First aid until you reach the hospital:

1. Call an emergency veterinarian immediately and drive straight to the clinic—time is of the essence.
2. Keep the dog calm; do not rush it; do not offer it water or food.
3. Do not attempt to decompress the animal on your own (do not insert tubes without veterinary guidance—risk of perforation).
4. If there are clear signs of shock: Lay the dog down in a warm place, speak calmly, and minimize stress.

Treatment at the clinic:

Emergency veterinary treatment includes intravenous fluid therapy to treat shock, gastric decompression (via a nasogastric tube or puncture), followed by emergency surgery to reposition the stomach, assessment for tissue necrosis, and gastropexy for permanent fixation.

Common Mistakes & Myths

• “I’ll wait and see for now.” With gastric torsion, waiting can be fatal. Every hour without treatment increases the risk of gastric tissue necrosis—and when gastric tissue becomes necrotic, the mortality rate rises to 30–50% or higher.
• “Elevated food bowls help prevent gastric torsion.” Glickman et al. (2000) demonstrated an association between elevated food bowls and an increased risk of GDV. The evidence is inconclusive, and there is no evidence to support the recommendation of elevated bowls as a preventive measure.
• "A bloated stomach after Eat is normal." Mild bloating can be harmless—but when combined with unsuccessful retching, restlessness, and weakness, it is a sign of an emergency.
• “Small dogs don’t get gastric torsion.” It’s rare, but not impossible. The main anatomical characteristic is a deep, narrow chest, not just the dog’s size.
• “After the surgery, everything is fine—no further follow-up is necessary.” Without gastropexy, there is a significant risk of recurrence. Gastropexy reduces this risk to less than 5%, so it is recommended even after a GDV if it was not performed during the emergency surgery.

Current State of Research (2026)

GDV research in recent years has focused on three areas: prognostic markers, preventive surgery, and postoperative inflammation management. Bruchim et al. (2025, PubMed 40003061) analyzed 130 cases of GDV and confirmed that blood lactate levels, preoperative cardiac arrhythmias, and gastric tissue necrosis are the strongest negative prognostic indicators. A Frontiers study (2023) investigated a 24-hour lidocaine infusion to attenuate the systemic inflammatory response in GDV—with promising results, but not yet with guideline status. Laparoscopically assisted gastropexy as a minimally invasive preventive option is increasingly being used in high-risk breeds (Frontiers Vet. Sci. 2025). Open questions: Optimal timing of prophylactic gastropexy (during neutering vs. as a standalone procedure), role of the intestinal flora in GDV development.

Frequently Asked Questions

Which dog breeds are most commonly affected by gastric torsion?

Great Danes, Irish Wolfhounds, Gordon Setters, Weimaraners, Dobermans, Leonbergers, Bernese Mountain Dogs, and other large to giant breeds with deep chests are particularly at risk. Glickman et al. (2000) reported a lifetime risk of GDV of up to 36.7% in Great Danes.

How can I tell if my dog has a twisted stomach?

A combination of a visibly distended abdomen, unsuccessful retching, extreme restlessness, and excessive drooling is highly suspicious. If weakness or pale mucous membranes are also present, shock is suspected. If these symptoms occur, call the emergency vet immediately—don’t waste time just watching.

Can gastric torsion in dogs be prevented?

There is no 100% effective prevention. Eating several small meals instead of one large one, and avoiding strenuous exercise for 60 minutes after Eat, have proven effective. Prophylactic gastropexy in predisposed breeds reduces the lifetime risk to less than 0.3% and is a sensible option for dogs at high risk.

Can gastric torsion in dogs be cured?

With immediate emergency care and surgery, 80–90% of affected dogs survive if no stomach tissue has died. Without treatment, most dogs die within a few hours from shock and organ damage.
