Dog gut, vomiting & bloat emergencies
A dog's digestive emergencies range from the minutes-matter crisis of bloat (gastric dilatation-volvulus) to the rapid dehydration of repeated vomiting, bloody diarrhoea, or a sudden refusal to eat. Because some of these escalate within hours, it is safer to call a veterinarian early than to wait and watch. The guides below help you recognise the red flags, act correctly while you reach care, and understand the vet-led recovery that follows.

When any of these is a go-now emergency
Treat collapse, non-stop vomiting or retching, a swollen hard belly, suspected poisoning, trouble breathing, a seizure lasting more than a few minutes, or heavy bleeding as a call-the-vet-now situation. When in doubt, phone an emergency animal hospital and describe the signs — they will tell you whether to come straight in.
Frequently asked questions
How do I know if my dog has bloat or just an upset stomach?
Bloat (GDV) comes on fast with a swollen, hard belly and repeated retching that brings nothing up, and the dog is restless and distressed. A simple upset stomach is milder, without a tense, swollen abdomen. Any swollen, hard belly with unproductive retching is a go-now emergency.
When is dog vomiting or diarrhoea an emergency?
Treat repeated vomiting, blood, inability to keep water down, a swollen belly, or vomiting or diarrhoea with weakness or collapse as an emergency. Puppies, small dogs and seniors dehydrate fastest, so see a vet sooner.
Can I treat my dog's gut upset at home?
Keep water available and call your vet before giving anything — human medicines can be harmful. Recovery products such as DiaTab are supportive options used after a vet has assessed your dog, not an emergency treatment.
