Dogs can vomit occasionally from eating too fast, dietary changes, motion sickness, or getting into something they shouldn’t. But repeated vomiting (more than once), vomiting that lasts over several hours, or vomiting paired with lethargy, not eating, diarrhea, bloating, abdominal pain, or dehydration can signal something more serious like pancreatitis, an infection, toxin exposure, or even an intestinal blockage. Puppies, seniors, and small dogs can also become dehydrated quickly.
