Dog Keeps Throwing Up? Causes & Treatment Explained

Is your furry friend throwing up frequently? Dog vomiting is a common symptom of an upset stomach or intestinal tract. It can be caused by various factors such as eating too quickly, consuming spoiled food, or even stress. As a pet owner, it’s important to pay attention to the color and consistency of your dog’s vomit. Brown vomit may indicate the presence of intestinal parasites or foreign objects in the stomach. If you notice yellow vomit, it could be a sign of possible causes such as liver disease or pancreatitis. It’s recommended to consult with your family veterinarian to determine the reasons behind your dog’s vomiting.

Regurgitation can also occur due to intestinal upset, and it’s important to know the possible causes. Common reasons include vomiting on an empty stomach or foreign body obstruction. If you notice any signs of regurgitation or vomiting, it’s best to take your dog to the family veterinarian for diagnosis and treatment.

So let’s cut to the chase and learn more about this common issue that affects our beloved pets! If your dog vomits frequently, it could be a sign of intestinal upset. It’s important to consult with your family veterinarian to rule out any underlying health issues. Additionally, keep an eye on your pet during hot weather as heat can also contribute to vomiting.

Top Reasons Why Dogs Vomit

If your dog keeps throwing up, it can be a concerning and frustrating experience. Vomiting is a symptom that should not be ignored, and it may indicate an underlying health issue that requires attention from a vet. It’s important to note if your dog is vomiting on an empty stomach or if there could be a foreign body causing the issue.

Common Reasons Why Dogs Vomit

  1. Eating too fast is one of the common reasons why your dog may need to see a vet. If your dog eats too quickly, they may vomit shortly after eating. This is because they are swallowing air along with their food, which can cause stomach upset.
  2. Dietary indiscretion: Dogs have a need to explore and may end up ingesting things they shouldn’t, such as garbage or toxic substances like chocolate or plants. This can lead to vomiting as their body tries to get rid of the harmful substance, which can also cause a dull coat sheen.
  3. Motion sickness: Some dogs with a sheen coat get motion sickness while traveling in cars or other vehicles, which can cause them to vomit.
  4. Stress and anxiety: Similar to humans, dogs may experience stress and anxiety that can result in vomiting with a glossy sheen.

Possible Causes of Vomiting in Dogs

  1. Bloat: Bloat is a serious condition where a dog’s stomach fills with gas and twists on itself. This can cause severe pain and vomiting, and it requires immediate veterinary attention. The sheen of the dog’s coat is not affected by bloat.
  2. Pancreatitis: Inflammation of the pancreas can cause vomiting in dogs, along with other symptoms such as diarrhea and abdominal pain. However, if your dog’s vomit has a sheen to it, it could be a sign of a more serious condition and you should seek veterinary care immediately.
  3. Kidney disease: Dogs with kidney disease may vomit due to high levels of toxins building up in their bloodstream, causing a dull sheen on their coat.
  4. Liver disease: Liver disease can also cause vomiting in dogs due to an accumulation of toxins in the body.
  5. Inflammatory bowel disease (IBD): IBD is a chronic condition where the lining of the digestive tract becomes inflamed, leading to symptoms such as vomiting and diarrhea.
  6. Parasites: Certain parasites such as roundworms or hookworms can cause vomiting in dogs.

Bloat as a Potential Cause of Vomiting in Dogs

Bloat is a life-threatening condition that can cause vomiting in dogs. It is more common in large, deep-chested breeds such as Great Danes and Dobermans. Symptoms of bloat include:

  • Unsuccessful attempts to vomit
  • Restlessness and pacing
  • Swollen or distended abdomen
  • Rapid breathing
  • Weakness and collapse

If you suspect your dog has bloat, seek veterinary attention immediately, especially if they are experiencing brown vomit.

Parasites as an Underlying Cause of Vomiting in Dogs

Parasites such as roundworms, hookworms, and giardia can cause vomiting in dogs. These parasites can be contracted through contaminated soil or water, or from other infected animals. Other symptoms of parasite infestation may include diarrhea, weight loss, and lethargy.

To prevent parasitic infections, make sure your dog receives regular deworming medication and avoid letting them drink from stagnant bodies of water. If you notice brown vomit, seek veterinary attention immediately.

When to see a vet for dog vomiting

Vomiting is a common problem in dogs, and it can be caused by many different things. While occasional vomiting may not be a cause for concern, frequent vomiting can lead to dehydration and other health complications.

Frequent vomiting can lead to dehydration and other health complications in dogs

If your dog is vomiting frequently, they may become dehydrated. Dehydration occurs when your dog loses more fluids than they take in. Signs of dehydration include dry mouth and nose, sunken eyes, lethargy, and loss of skin elasticity. If left untreated, dehydration can lead to organ failure or even death.

Frequent vomiting can also indicate an underlying health condition that requires veterinary attention. Some conditions that may cause repeated vomiting include:

  • Gastrointestinal blockages
  • Kidney disease
  • Liver disease
  • Pancreatitis
  • Inflammatory bowel disease

Vomiting accompanied by other symptoms may indicate a serious underlying condition

If your dog is experiencing other symptoms along with their vomiting, it may indicate a more serious underlying condition. Some symptoms to watch out for include:

  • Lethargy or weakness
  • Diarrhea
  • Loss of appetite
  • Abdominal pain or bloating
  • Blood in vomit or stool

If you notice any of these symptoms along with your dog’s vomiting, it is important to seek veterinary care immediately.

Seek veterinary care if your dog has been vomiting for more than 24 hours or if you notice any concerning symptoms

If your dog has been throwing up for more than 24 hours or if you notice any concerning symptoms such as those listed above, it is important to seek veterinary care as soon as possible.

Your veterinarian will perform a physical examination and may recommend diagnostic tests such as blood work, X-rays, or an ultrasound to determine the underlying cause of your dog’s vomiting. Treatment will depend on the underlying cause and may include medication, dietary changes, or surgery.

Treatment options for dog vomiting at the vet’s office

Family veterinarian diagnosis through diagnostic tests

If your dog keeps throwing up, it is essential to seek medical attention from a family veterinarian. A veterinarian can diagnose the cause of your dog’s vomiting through diagnostic tests, which may include blood work, x-rays, and ultrasound.

Blood work helps identify any abnormalities in your dog’s organs or blood cells that could be causing vomiting. X-rays can reveal if there are any foreign objects or blockages in your dog’s digestive system. An ultrasound can help detect tumors or other abnormalities in your dog’s organs.

Once the cause of your dog’s vomiting has been identified, your veterinarian will recommend appropriate treatment options.

Medication and Surgery

Treatment options for dogs experiencing persistent vomiting vary depending on the underlying cause. In some cases, medication may be prescribed to help reduce nausea and prevent further vomiting. Common medications used for this purpose include antiemetics such as Cerenia and Reglan.

In more severe cases where medication alone is not enough to treat the underlying condition causing the vomiting, surgery may be required. Surgery may be necessary if there is an obstruction in the digestive tract or if there is a tumor present.

Your veterinarian will discuss all available treatment options with you and make recommendations based on your dog’s individual needs.

Preventing Dog Vomiting

While some causes of dog vomiting cannot be prevented, there are steps you can take to reduce the risk of certain types of vomiting:

  • Feed your dog smaller meals more frequently throughout the day.
  • Avoid giving your dog table scraps or foods that are high in fat.
  • Make sure your dog has access to clean water at all times.
  • Keep toxic substances out of reach.
  • Ensure that any changes to your dog’s diet are made gradually over several days.

Helping Your Sick Dog

If you suspect that something is wrong with your furry friend, it is essential to seek medical attention from a veterinarian as soon as possible. In the meantime, there are some things you can do to help your dog feel more comfortable:

  • Keep your dog hydrated by offering small amounts of water frequently.
  • Offer bland foods such as boiled chicken or rice.
  • Keep your dog calm and quiet to help reduce stress and anxiety.
  • Monitor your dog’s symptoms closely and report any changes to your veterinarian.

Medications for Nausea and Vomiting in Dogs

If your dog keeps throwing up, it can be a cause for concern. Vomiting is often a sign of an underlying health issue or disease. In some cases, medications may be prescribed to alleviate the symptoms of nausea and vomiting in dogs. Here’s what you need to know about medications for nausea and vomiting in dogs.

Antiemetic Drugs

Antiemetic drugs are commonly prescribed by veterinarians to treat nausea and vomiting in dogs. These drugs work by blocking certain receptors in the brain that trigger the sensation of nausea and vomiting. Some common antiemetic drugs used in dogs include:

  • Cerenia (maropitant citrate): This drug is FDA-approved for use in dogs to prevent acute vomiting due to motion sickness or chemotherapy.
  • Metoclopramide: This drug works by increasing muscle contractions in the digestive tract, which helps dog vomit move through more quickly.
  • Ondansetron: This drug blocks serotonin receptors in the brain that trigger nausea and vomiting.

It’s important to note that these drugs should only be given under the guidance of a veterinarian. Dosages will vary depending on your dog’s weight, age, and overall health.

Other Medications

In addition to antiemetic drugs, there are other medications that may be prescribed to treat underlying conditions that cause nausea and vomiting in dogs. For example:

  • Antibiotics: If your dog has an infection that is causing them to vomit, antibiotics may be prescribed.
  • Steroids: In some cases, steroids may be used to reduce inflammation or swelling that is causing nausea and vomiting.
  • Probiotics: If your dog’s gastrointestinal system is out of balance, probiotics may help restore healthy gut bacteria.

Again, it’s important to consult with a veterinarian before giving any medication to your dog. Some medications can have serious side effects if not given in the correct dosage or if given to dogs with certain health conditions.

Home Remedies

If your dog is experiencing mild nausea or vomiting, there are some home remedies that may help alleviate their symptoms. These include:

  • Fasting: If your dog has been vomiting, it’s best to withhold food for 12-24 hours to give their digestive system a chance to rest.
  • Small, frequent meals: Once your dog’s vomiting has stopped, you can start feeding them small meals of bland foods like boiled chicken and rice.
  • Ginger: Ginger is a natural anti-inflammatory that can help soothe an upset stomach. You can give your dog ginger in the form of capsules or by adding fresh ginger to their food.

Again, it’s important to consult with a veterinarian before trying any home remedies. Some remedies may not be safe for all dogs, especially those with underlying health conditions.

Dietary Indiscretion or Serious Concern?

When a dog keeps throwing up, it can be concerning for pet owners. Vomiting is a common issue in dogs that can indicate either mild or serious health problems. In some cases, the cause of vomiting may be due to dietary indiscretion, while other times it may indicate a more severe condition. It’s important to understand the possible causes of vomiting and how to address them effectively.

Dietary Indiscretion as a Common Cause

Dietary indiscretion is one of the most common reasons why dogs vomit. This term refers to when a dog eats something they shouldn’t have or consumes too much food too quickly. Dogs are known for their love of eating, and sometimes their enthusiasm gets the better of them.

When dogs eat something that doesn’t agree with them, such as spoiled food or garbage, they may experience gastrointestinal upset that leads to vomiting. If a dog eats too much food at one time or eats too quickly, they may also vomit.

If your dog has vomited once or twice and seems otherwise healthy and active, then dietary indiscretion is likely the cause. However, if your dog continues to vomit repeatedly over several days or shows other symptoms such as diarrhea or lack of appetite, then it’s time to consider other potential causes.

Serious Health Issues

While dietary indiscretion is often the cause of vomiting in dogs, there are times when more serious health issues are responsible. Food allergies can cause vomiting in dogs when they consume foods that trigger an allergic reaction. Some breeds are more prone to food allergies than others.

In addition to allergies, there are many diseases that can cause vomiting in dogs. These include pancreatitis, kidney disease, liver disease, and cancer. If your dog has been consistently vomiting for several days without improvement or shows other symptoms such as lethargy and lack of appetite along with vomiting episodes; it’s important to see a veterinarian right away.

Undigested Food in Vomit

When a dog vomits, it’s not uncommon to see undigested food in the vomit. This can be an indication that your dog has issues with their diet or digestive system. If your dog is vomiting up whole pieces of kibble or other food items, it may mean they are not chewing their food properly or eating too quickly.

If you notice undigested food in your dog’s vomit, consider switching to a more easily digestible diet. A bland diet consisting of boiled chicken and rice can help alleviate vomiting caused by dietary indiscretion or mild illness. Make sure your pet has access to plenty of fresh water as dehydration can exacerbate vomiting episodes.

Common conditions characterized by dog vomiting

Dogs are known for their love of eating and, unfortunately, throwing up. It’s not uncommon for dogs to vomit occasionally, but chronic vomiting can be a symptom of various diseases or conditions in dogs.

Acute Vomiting

Acute vomiting is often caused by a sudden change in diet or the ingestion of something toxic. Dogs may also vomit due to motion sickness or stress. If your dog has been vomiting for less than 24 hours and is otherwise healthy, it’s likely an acute case and will resolve on its own. However, if your dog is lethargic, dehydrated, or showing other concerning symptoms, you should consult with your veterinarian.

Chronic Vomiting

Chronic vomiting is defined as vomiting that occurs more than once a week for several weeks. There are many potential causes of chronic vomiting in dogs including:


Pancreatitis is a common condition that can cause vomiting in dogs. The pancreas produces enzymes that aid digestion, and when these enzymes become activated within the pancreas itself instead of the small intestine where they belong, inflammation occurs which leads to pancreatitis. Symptoms include abdominal pain, diarrhea and/or constipation along with loss of appetite.

Kidney Disease

Kidney disease can also cause chronic vomiting in dogs as toxins build up in their system due to kidney function failure.

Liver Disease

Liver disease can cause chronic vomiting due to the buildup of toxins in the bloodstream since liver function cannot filter them out properly.

Gastrointestinal Issues

Gastrointestinal issues like inflammatory bowel disease (IBD) or intestinal parasites can result in chronic vomiting among other symptoms such as diarrhea and weight loss.


Cancerous growths within the digestive tract may lead to persistent nausea and frequent bouts of vomitting.


Aside from vomiting, other symptoms may accompany your dog’s condition. Lethargy and loss of appetite are common in dogs with chronic vomiting. Dehydration is also a concern if your dog is not drinking enough water or unable to keep fluids down. If you notice any of these symptoms, it’s essential to take your dog to the vet right away.

Conclusion and advice for pet owners if a dog keeps throwing up

In conclusion, understanding the reasons behind your dog’s vomiting is crucial in determining whether it requires medical attention or not. While some causes such as dietary indiscretion can be resolved with simple home remedies, other underlying conditions may require prompt veterinary attention.

If your dog keeps throwing up, always monitor its behavior and symptoms closely. It is essential to seek veterinary care when the vomiting persists for more than 24 hours or accompanied by other concerning symptoms such as lethargy, diarrhea, or loss of appetite.

At the vet’s office, treatment options for dog vomiting may include medications to control nausea and vomiting. Your veterinarian may also recommend diagnostic tests to rule out underlying health issues that could be causing your dog’s symptoms.

To prevent future occurrences of vomiting in dogs, ensure you feed them a well-balanced diet that meets their nutritional needs. Avoid giving them human food scraps or table scraps that can cause gastrointestinal upset.

Remember to provide plenty of clean water at all times and avoid sudden changes in your dog’s diet or routine. Regular exercise and maintaining good hygiene practices are also essential in keeping your furry friend healthy.
