Common causes
Dietary indiscretion, abrupt diet change, gastroenteritis, parasites, pancreatitis, foreign bodies, medications, kidney or liver disease, endocrine disease, and toxins can all cause vomiting. Age and medical history alter the risk profile.
Vomiting or regurgitation?
Vomiting is usually active and may include nausea and abdominal contractions. Regurgitation is more passive and often occurs soon after eating. Video can help a veterinary team distinguish the two.
What should I record?
Frequency, appearance, time relative to meals, stool, appetite, water intake, recent foods, garbage access, medications, and possible toy or toxin exposure are useful. Do not induce vomiting unless specifically advised by a veterinary or poison-control professional.
When testing is needed
Persistent or severe cases may need bloodwork, radiographs, ultrasound, fecal testing, or other diagnostics. Puppies, seniors, and dogs with chronic disease generally deserve a lower threshold for evaluation.
