Dog bloat / GDV (swollen, hard belly)
A dog with a suddenly swollen, hard belly who is retching without bringing anything up, drooling, pacing and restless is a life-threatening emergency — go to a veterinarian or emergency hospital immediately. This pattern points to bloat, and to gastric dilatation-volvulus (GDV), where the stomach fills with gas and twists. GDV can become fatal within hours, so do not wait to “see if it settles.” Deep-chested breeds are at highest risk, but it can happen to any dog. Call ahead so the hospital is ready.
Go to a vet now if
- A swollen, tight or drum-like abdomen that came on quickly
- Repeated unproductive retching — trying to vomit but nothing (or only foam) comes up
- Restlessness, pacing, unable to settle, looking at the belly
- Heavy drooling, pale gums, weakness or collapse
Call a vet today if
- Mild gassiness or a single burp that resolves and the dog is otherwise normal
- A known sensitive stomach with no swelling, retching or distress
What to tell the vet
- When the swelling and retching started
- Whether anything is coming up when they retch
- Recent large meal, gulped food, or exercise after eating
- Breed and chest depth
- Gum colour and whether they have collapsed
- Weight, age and any past bloat episodes
What not to do
- Do not wait to see if it passes — GDV worsens by the minute
- Do not try to make your dog vomit or give home remedies
- Do not give food or large amounts of water
What your vet may check
Your vet may decompress the stomach, take an X-ray to confirm a twist, start fluids for shock, and assess the heart. Confirmed GDV usually needs emergency surgery; the sooner it is treated, the better the outlook.
Recovery support after veterinary assessment
After surgery and stabilisation, your vet will guide a careful return to eating with small, easily digested meals. Supportive recovery options positioned for this stage include Alfavet ReConvales Tonicum or ReConvales Power to help encourage intake during convalescence — used only after assessment and on your vet's advice, never as a response to a suspected bloat.
Frequently asked questions
How fast does bloat kill a dog?
GDV can become life-threatening within a few hours of starting. Because the stomach can twist and cut off circulation, any swollen, hard belly with unproductive retching is a go-now emergency.
Which dogs are most at risk of GDV?
Large, deep-chested breeds (such as Great Danes, German Shepherds, Standard Poodles, Weimaraners) are highest risk, but bloat can affect any dog, especially after a large meal eaten quickly.
Can I treat bloat at home?
No. There is no safe home treatment for GDV — it needs decompression, imaging and usually surgery. Get to an emergency hospital immediately rather than trying remedies.
How can I lower the risk of bloat?
Feeding smaller meals, slowing fast eaters, and avoiding hard exercise right after eating may help. High-risk breeds can discuss a preventive gastropexy with their vet.
