Vomiting is one of the most worrying symptoms a dog owner can face, especially when it happens repeatedly.
A dog constantly throwing up is not only distressing to watch but can also point to serious underlying health issues.
We outline the common reasons for constant throwing up in dogs, what you can do at home, and when to seek veterinary help.
Dog Constantly Throwing Up — Why It Happens
Dogs may throw up frequently due to digestive problems, dietary indiscretions, infections, or more serious underlying diseases. Sometimes vomiting is caused by something minor, like eating too fast or consuming spoiled food, but persistent vomiting can signal conditions such as pancreatitis, kidney or liver disease, intestinal blockages, or even poisoning.
Because constant vomiting can lead to dehydration and weakness, it’s important to understand the possible causes.
Dog Constantly Throwing Up: Common Causes
Dietary Indiscretion
Dogs are known for eating things they shouldn’t. Consuming garbage, spoiled food, or foreign objects can irritate the stomach and intestines. This often leads to repeated vomiting as the body attempts to expel the offending material.
Pet owners may also notice diarrhea, abdominal pain, or loss of appetite. If vomiting doesn’t stop within a day or two, the risk of dehydration becomes high, and veterinary care is needed.

Gastrointestinal Obstruction
When a dog swallows a toy, bone, or other foreign object, it can get stuck in the digestive tract. This blockage prevents food and water from moving through normally, causing repeated vomiting.
In these cases, vomiting may happen shortly after eating or drinking. Dogs might also become lethargic, drool excessively, or strain without producing stool. Obstructions are life-threatening and require immediate veterinary attention, often surgery.
Pancreatitis
Pancreatitis, or inflammation of the pancreas, is a painful condition that can cause dogs to vomit repeatedly. It is often triggered by fatty foods, though it can also occur for unknown reasons.
Affected dogs may refuse food, show signs of abdominal pain, hunch their backs, or appear very lethargic. Because pancreatitis can become severe quickly, persistent vomiting in a dog with these signs should never be ignored.
Kidney or Liver Disease
Chronic organ issues, particularly with the kidneys or liver, can result in frequent vomiting. These organs play a role in filtering toxins and maintaining balance in the body. When they fail, nausea and vomiting are common.
Pet owners may notice increased thirst, changes in urination, weight loss, or yellowing of the gums and eyes. Such conditions are progressive and require ongoing veterinary management.
Infections and Parasites
Bacterial or viral infections, such as parvovirus, can cause relentless vomiting. Intestinal parasites may also trigger stomach upset and frequent vomiting.
These causes are often accompanied by diarrhea, lethargy, and sometimes blood in the stool or vomit. Puppies are especially vulnerable and can deteriorate rapidly, requiring emergency veterinary intervention.
Poisoning or Toxins
Dogs that ingest toxins such as household chemicals, poisonous plants, or certain human foods (like grapes or chocolate) may vomit repeatedly as their bodies react.
Other symptoms of poisoning include drooling, tremors, seizures, or collapse. If you suspect your dog has consumed something toxic, immediate veterinary care is critical, as some toxins are fatal without rapid treatment.
What to Do If Your Dog Is Constantly Throwing Up
If your dog is vomiting frequently, the first step is to remove food and water for a short period to allow the stomach to settle. After several hours, small sips of water can be reintroduced, followed by bland food such as boiled chicken and rice once vomiting has eased.
It’s important to monitor your dog closely during this time. If vomiting resumes after food or water, or if your dog is unable to keep anything down, seek veterinary help quickly.
Comfort your dog by keeping them in a calm, quiet environment. Avoid giving over-the-counter medications unless directed by your veterinarian, as some human medicines are toxic to dogs. Gentle care and close observation can make a big difference while you decide whether vet care is required.
When to Call or Visit Your Vet
Seek immediate veterinary care if your dog’s vomiting is continuous, severe, or accompanied by alarming signs. Warning signs include blood in vomit, inability to keep water down, weakness or collapse, bloated abdomen, or signs of pain when touched.
Puppies, senior dogs, and those with chronic illnesses are at greater risk from vomiting and dehydration. Even if vomiting seems mild, these vulnerable groups may need urgent medical care.
If your dog vomits once but is otherwise acting normal, you can observe for a short time. However, if vomiting becomes constant, veterinary evaluation is always the safest choice.

Key Takeaway
A dog constantly throwing up should never be dismissed as a minor issue. While occasional vomiting may happen from overeating or mild stomach upset, persistent vomiting can signal dangerous conditions like blockages, organ disease, or poisoning.
Caring owners should monitor symptoms closely, provide comfort at home, and contact their veterinarian when vomiting doesn’t stop or is accompanied by other worrying signs. With quick action and proper treatment, many dogs recover well and regain their energy.
