# Dog Vomiting — Quick answer

PETHEALTH+ (https://pethealth.org.uk/health/dog-vomiting-causes): Dog Vomiting — Quick answer. Dogs vomit for many reasons — from eating too fast to infections, toxins, and organ disease. A single episode in an otherwise well dog may need only rest and observation. Call your vet if vomiting is repeated, contains blood, or is paired with lethargy, pain, or inability to drink — especially in puppies and senior dogs. Out of hours, use the Vets Now clinic finder.

PETHEALTH+ (https://pethealth.org.uk/health/dog-vomiting-causes): Dog Vomiting — Key takeaways. A single vomit in an otherwise bright adult dog may need only rest and observation — repeated vomiting is different. Go to an emergency vet for blood in vomit, inability to keep water down, a swollen abdomen with unproductive retching (possible bloat), collapse, or suspected toxin. Puppies and small breeds dehydrate quickly — if your practice is closed, use the Vets Now clinic finder.

PETHEALTH+ (https://pethealth.org.uk/health/dog-vomiting-causes): Dog Vomiting — Acute vs chronic vomiting. Acute vomiting starts suddenly and often resolves within a day or two — commonly caused by dietary indiscretion, sudden food changes, or mild infections. Chronic vomiting persists for weeks or recurs regularly. It warrants thorough investigation for conditions such as inflammatory bowel disease, pancreatitis, liver disease, kidney failure, or cancer. Keeping a log of frequency, appearance, and timing helps your vet distinguish between the two.
