Gastric Dilatation-Volvulus is one of the most time-sensitive emergencies in veterinary medicine. The difference between a dog that survives GDV and one that does not often comes down to how quickly the owner recognised the signs and sought treatment. This guide will help you identify the seven warning signs at every stage so you can act fast when it matters most.
What Is GDV (Gastric Dilatation-Volvulus)?
GDV, commonly known as bloat, occurs when a dog’s stomach fills with gas, food, or fluid (dilatation) and then rotates on its axis (volvulus). This rotation traps the stomach contents inside, cuts off blood supply to the stomach wall and spleen, and compresses the major veins that return blood to the heart.
Once the stomach twists, gas continues to build with no way to escape. Blood flow is compromised, tissue begins to die, toxins flood the bloodstream, and the dog enters cardiovascular shock. Without emergency surgical intervention, GDV is fatal — often within hours of the first symptoms appearing.
Understanding these warning signs can mean the difference between life and death. Every minute counts.
Emergency Veterinary Medicine
Sign 1: Unproductive Retching
Trying to Vomit, but Nothing Comes Up
This is the single most telltale sign of GDV. Your dog will retch, gag, or appear to try to vomit repeatedly, but produces little to nothing — perhaps only small amounts of foam or mucus. Because the stomach has twisted, the contents are trapped and cannot be expelled normally.
If your dog is making repeated, unsuccessful attempts to vomit — especially after a meal — treat this as an emergency. Do not wait to see if it resolves on its own.
Sign 2: Distended or Swollen Abdomen
Visibly Bloated Stomach That Feels Tight Like a Drum
As gas accumulates in the trapped stomach, the abdomen becomes visibly enlarged and distended. When touched, the belly feels abnormally tight and taut — often described as feeling like a drum. The swelling typically appears behind the rib cage and may develop quickly over the course of an hour or less.
In deep-chested breeds, bloating can be harder to spot visually. If you notice any unusual firmness or swelling in the abdominal area after eating, do not dismiss it. Tap the swollen area gently — a hollow, drum-like sound (tympany) strongly suggests gas distension.
Sign 3: Restlessness and Pacing
Cannot Get Comfortable, Pacing and Looking at Abdomen
A dog experiencing GDV is in significant pain and discomfort. You will notice your dog pacing back and forth, unable to lie down or settle. They may repeatedly stand up and lie down, change positions frequently, whine, or look back at their abdomen as if trying to understand the source of the pain.
This restlessness is a clear indication of abdominal distress. Combined with any other sign on this list, it warrants an immediate call to your vet or emergency animal hospital.
Sign 4: Excessive Drooling
More Saliva Than Normal, Thick and Ropy
Excessive salivation or hypersalivation is a common sign of nausea and gastric distress in dogs with GDV. The drool may appear thicker and ropier than normal. Your dog may also lick their lips repeatedly, a hallmark sign of nausea.
While many conditions can cause drooling, when combined with retching and restlessness, excessive drooling strongly suggests a gastric emergency that requires immediate veterinary attention.
Sign 5: Rapid Heartbeat and Weak Pulse
Cardiovascular Compromise
As GDV progresses, the twisted stomach compresses major blood vessels, particularly the caudal vena cava, reducing blood return to the heart. The heart compensates by beating faster, but the pulse becomes weak and thready. You may be able to feel a rapid heartbeat by placing your hand on your dog’s chest, but the pulse at the femoral artery (inner thigh) will feel faint or difficult to detect.
A rapid heart rate with weak pulse indicates that your dog is going into cardiovascular shock. This is a medical emergency requiring immediate veterinary intervention.
Sign 6: Pale or White Gums
Blood Circulation Failure — Check Capillary Refill Time
Healthy dogs have pink, moist gums. When GDV causes circulatory compromise, the gums turn pale, white, grey, or even bluish. You can check capillary refill time (CRT) by pressing a finger firmly against the gum for two seconds, then releasing. In a healthy dog, the pink colour returns within 1–2 seconds. In a dog with GDV, the colour returns slowly or the gums remain pale.
Pale gums indicate that your dog’s body is not circulating blood effectively. This is a late-stage sign indicating shock and tissue oxygen deprivation. Your dog needs emergency care now.
Sign 7: Collapse or Weakness
Late-Stage Sign Requiring IMMEDIATE Emergency Care
If your dog collapses, cannot stand, shows severe weakness in the hind legs, or becomes unresponsive, GDV has progressed to a critical and life-threatening stage. The dog’s body is shutting down due to toxins released from dying stomach tissue, severe pain, and cardiovascular collapse.
At this stage, survival depends entirely on how quickly the dog reaches an emergency veterinary hospital. Do not attempt any home remedies. Carry your dog to your vehicle and drive directly to the nearest emergency vet. Call ahead if possible so they can prepare.
You do not need to observe all seven signs to act. Even one or two of these symptoms — especially unproductive retching combined with abdominal distension — is enough to warrant an immediate trip to the emergency vet. When in doubt, call ahead and go. A false alarm is always better than arriving too late.
Risk Factors for GDV
While any dog can develop GDV, certain factors significantly increase the risk. Understanding these can help you assess your own dog’s vulnerability and take preventive action.
Prevention Strategies
While GDV cannot be entirely prevented, several evidence-based strategies can meaningfully reduce your dog’s risk. The most impactful measures target the modifiable risk factors identified in veterinary research.
- Feed two or three smaller meals per day instead of one large meal. This reduces the volume of food and gas in the stomach at any given time and is one of the most consistently recommended strategies.
- Slow down eating speed. Use a slow feeder bowl or puzzle feeder to prevent gulping and reduce air swallowing. Fast eating is one of the strongest modifiable risk factors for GDV.
- Avoid vigorous exercise for at least one hour after meals. Allow your dog to rest and digest before any running, playing, or rough activity.
- Know your breed’s risk level. If you own a large or giant breed, discuss prophylactic gastropexy with your vet — a surgical procedure that tacks the stomach to the abdominal wall and dramatically reduces GDV risk.
- Reduce stress at mealtimes. Feed dogs in separate areas in multi-pet households and maintain a consistent feeding schedule.
- Ensure fresh water is always available, but discourage dogs from drinking large amounts immediately before or after meals.
How SlowBowl Helps Reduce Bloat Risk
Because fast eating is one of the most significant modifiable risk factors for GDV, slowing down your dog’s eating speed is one of the most practical steps you can take. The SlowBowl by Kept Home is specifically designed to address this risk factor.
- Slows eating by up to 5x, extending meals from seconds to several minutes of engagement
- Promotes smaller bites as dogs work food from textured ridges rather than scooping large mouthfuls
- Reduces air gulping (aerophagia) — the primary mechanism linking fast eating to gastric distension
- Food-grade rubber with suction-cup base for stability, dishwasher safe for easy cleaning
A slow feeder bowl is NOT a cure for GDV and cannot guarantee prevention. It is a risk-reduction tool that addresses one modifiable factor. Always consult your veterinarian about a comprehensive bloat prevention plan tailored to your dog’s breed, size, and individual risk profile.

Emergency Action Checklist: What to Do If You Suspect GDV
If You Suspect GDV, Act Now
- Call your emergency vet immediately. Call ahead so they can prepare for your arrival. If your regular vet is closed, call the nearest 24-hour emergency animal hospital.
- Do NOT wait to see if symptoms improve. GDV does not resolve on its own. Every minute of delay reduces your dog’s chances of survival.
- Do NOT attempt home remedies. Do not try to relieve gas yourself, do not give medications, do not try to make your dog vomit, and do not give food or water. These actions waste critical time and can cause further harm.
- Keep your dog as calm as possible. Minimise movement and stress during transport. If your dog cannot walk, carefully carry or slide them onto a blanket to use as a stretcher.
- Drive directly to the emergency vet. Do not stop for anything. If possible, have someone else drive while you monitor your dog.
- Provide the vet with key information: when symptoms started, when your dog last ate, what they ate, how fast they ate, and any relevant medical history or breed information.
