Emergency
⚠️ See a vet immediately if you notice
- • Repeated attempts to vomit with nothing coming up (classic bloat/GDV sign)
- • Visibly swollen or hard abdomen
- • Vomiting three or more times in a row
- • Blood in vomit, or dark brown coffee-ground material
- • Extreme weakness or collapse
✅ These can be monitored at home
- • Single vomiting episode with normal behavior afterward
- • Still willing to drink water after vomiting
- • Vomit is undigested food shortly after eating
Common Causes of Vomiting
Dogs vomit for all kinds of reasons, ranging from completely harmless to genuinely serious:
- Eating too fast or too much: The most common cause — usually nothing to worry about
- Something that didn't agree with them: Garbage, table scraps, grass, or unfamiliar food
- Motion sickness: Common in dogs that aren't used to car rides
- Gastroenteritis: A viral or bacterial infection of the stomach and intestines
- Foreign body obstruction: A swallowed toy, bone fragment, or other object causing a blockage
- Toxin ingestion: Certain plants, household chemicals, medications, or toxic foods
- Underlying illness: Pancreatitis, kidney disease, liver disease, intestinal tumors, and more
⚠️ Know the Signs of Bloat (GDV) — It Can Be Fatal
Gastric Dilatation-Volvulus (GDV), commonly called bloat, is one of the most life-threatening emergencies in dogs. The stomach fills with gas and twists on itself, cutting off blood flow.
Classic warning signs:
- The dog is retching or attempting to vomit repeatedly but nothing comes up
- The abdomen looks visibly swollen or feels hard and tight
- The dog is in obvious distress — restless, drooling, unable to get comfortable
- Rapid deterioration: weakness, pale gums, collapse
GDV is most common in large, deep-chested breeds (Great Danes, German Shepherds, Dobermans, Boxers, Standard Poodles), but can occur in any dog. If you suspect GDV, go to an emergency vet immediately — every minute matters.
When You Can Monitor at Home
- Vomited only once and seems completely fine afterward
- The vomit is undigested food (likely ate too fast)
- Still interested in water after vomiting
- No other symptoms present (no diarrhea, no fever, no bloating)
Home care:
- Withhold food for 4–6 hours to let the stomach rest (adult dogs only)
- Ensure fresh water is always available — vomiting causes fluid loss
- After the fasting period, offer a small amount of bland food: boiled chicken breast with plain white rice
- Gradually return to normal feeding over 2–3 days if no further episodes occur
Red Flags: See a Vet Immediately
- Repeated retching with nothing coming up, or bloated abdomen (possible GDV)
- Vomiting three or more times in a row
- Blood in the vomit, or vomit that resembles dark coffee grounds
- Vomiting alongside severe diarrhea, pain, or fever
- Extreme weakness — dog barely wants to move
- Suspected foreign object, toxin, or medication ingestion
- Vomiting in a puppy, senior dog, or a dog with known health conditions
