Why Is My Dog Vomiting? Common Causes and Emergency Warning Signs

Dogs may vomit after eating too fast, scavenging, changing foods, or developing a mild stomach upset. Repeated vomiting can also be caused by pancreatitis, intestinal obstruction, toxins, infections, metabolic disease, or other serious problems.

What information matters? Notice how often your dog vomits, what the material looks like, whether diarrhea is present, and whether the dog can keep water down. Appetite, energy level, abdominal comfort, and recent access to trash or foreign objects are also important.

Foreign bodies are a major concern Dogs commonly swallow socks, toys, bones, corn cobs, fabric, and other objects. A partial or complete intestinal blockage may cause vomiting, appetite loss, abdominal pain, and decreased stool production.

What can a veterinary workup involve? The veterinarian may perform bloodwork, fecal testing, X-rays, or ultrasound depending on the history and physical exam. If a toxin or foreign body is suspected, timing can matter.

Treatment Mild uncomplicated stomach upset may improve with veterinarian-guided supportive care and a feeding plan. Dehydration may require fluids. Pancreatitis, infection, organ disease, or other causes require targeted treatment. Foreign material may sometimes be removed endoscopically. Other cases require surgery.

Never give human anti-nausea medication or pain relievers without veterinary guidance.

Emergency warning signs Seek urgent care for repeated vomiting, blood, severe weakness, a swollen or painful abdomen, collapse, suspected toxin exposure, or possible foreign-body ingestion. Large deep-chested dogs with abdominal enlargement and repeated unproductive retching may have gastric dilatation-volvulus, a life-threatening emergency.
