Dog symptom
Bloated belly / trying to vomit in dogs
A swollen or tight belly with repeated unproductive retching can be gastric dilatation-volvulus (GDV, or bloat), a rapidly progressive life-threatening emergency in dogs.
Common causes of bloated belly / trying to vomit in dogs
- Gastric dilatation-volvulus (GDV), especially in large or deep-chested dogs
- Severe gas or stomach distension without twisting
- Gastrointestinal obstruction or severe abdominal pain
- Fluid, bleeding, or another cause of abdominal enlargement
Who's most at risk
- Large, deep-chested breeds (Great Dane, GSD, Weimaraner)
- Eating one big meal fast, or exercise right after eating
- Older dogs and those with a family history
- Stress and gulping air
What you can do at home
- Do not wait to see if it passes - go to an emergency clinic immediately
- Do not give food, water, antacids, or gas medicine unless a veterinarian directs it
- Keep your dog calm and transport gently
When to see a vet
- Repeated retching or trying to vomit with little or nothing coming up
- A swollen, tight, or painful belly
- Restlessness, drooling, weakness, pale gums, fast breathing, or collapse
- Signs started after eating, drinking, exercise, or in a large/deep-chested dog
When it's more serious
- This is classic bloat/GDV — a life-threatening emergency. Go to a vet or ER right now.
- GDV causes shock fast — do not wait, transport immediately.
- These breeds are highest-risk for GDV — treat a swollen belly plus retching as an emergency.
What your vet may do
- Rapid exam, X-rays to confirm GDV, and IV fluids for shock
- Decompress the stomach
- Emergency surgery to untwist the stomach and tack it (gastropexy)
- Intensive monitoring of heart rhythm afterward
Questions to ask your vet
- Is this bloat with a twist (GDV) needing surgery?
- Should we discuss a preventive gastropexy?
- What's the recovery and outlook?
- How do I lower the risk going forward?
