What to do now
Vomiting can follow mild stomach upset, but repeated episodes, blood, bloat signs, or toxin exposure need faster action.
Monitor
- Count vomit episodes and note whether food, bile, foam, or blood appears.
- Track water intake, appetite, stool, and energy.
- Record recent diet changes, trash access, medications, plants, or toxins.
Call a vet
- Call today if vomiting repeats or pairs with diarrhea, poor appetite, or low energy.
- Call sooner for puppies, seniors, or dogs with chronic disease.
- Ask whether food, water, or medication instructions should change before a visit.
Emergency now
- Use emergency care for repeated vomiting with weakness, collapse, blood, or severe pain.
- Use emergency care for a swollen belly, unsuccessful retching, or restlessness.
- Treat toxin or foreign-object exposure as urgent.
Red flags
- Repeated vomiting
- Blood or coffee-ground material
- Swollen abdomen or unsuccessful retching
- Collapse, weakness, or possible toxin exposure
