Dog vomiting can be a concerning symptom for pet owners. It can be caused by a variety of factors, ranging from a simple stomach upset to a more serious underlying medical condition. In this blog, we will explore the potential causes of dog vomiting and provide some examples to help you better understand the issue.
Vomiting and regurgitation
Vomiting and regurgitation are two different processes that can both involve the expulsion of material from the digestive tract. Here are some key differences between the both.
- Origin of material: Vomiting involves the expulsion of material that has already been digested and absorbed into the body. Regurgitation, on the other hand, involves the expulsion of material that has not yet been fully digested and absorbed.
- Pathway of material: Vomiting involves the active contraction of muscles in the stomach and intestine, which pushes the material up through the esophagus and out of the mouth. Regurgitation, on the other hand, involves the passive expulsion of material from the esophagus or pharynx, without the active contraction of muscles.
- The appearance of material: Vomited material is usually partially digested and may contain bile or other digestive juices. Regurgitated material, on the other hand, is usually undigested and may appear similar to the original food or drink consumed.
- Causes: Vomiting can be caused by a variety of factors, including infection, food poisoning, motion sickness, and certain medications. Regurgitation can be caused by a variety of factors as well, including mechanical obstruction in the esophagus, esophageal motility disorders, and certain medical conditions such as acid reflux or GERD.
Causes of dog acute vomiting
There are many potential causes of vomiting in dogs, including:
Eating something toxic
Ingesting something toxic such as garbage, plants, or chemicals can cause vomiting in dogs as a protective mechanism to remove the substance from their body. Vomiting can also be a sign of other underlying health issues, such as gastrointestinal problems or infections. It is important to keep any potentially harmful substances out of reach of your dog and to supervise your dog while they are outside to prevent accidental ingestion. If you are unsure whether a substance is toxic to dogs, it is best to err on the side of caution and keep it away from your pet. If you suspect that your dog has ingested something toxic or inedible, it is important to contact your veterinarian immediately for guidance.
Eating a new
Eating a new food that a dog is not used to can cause vomiting in dogs because their digestive system may not be able to handle the sudden change in diet. When a dog eats something new, their body may try to get rid of it by vomiting. This is a natural protective mechanism that helps to remove potentially harmful substances from the body. There are a few other reasons why a dog may vomit after eating a new food:
- Food intolerance or allergy: Some dogs may have an intolerance or allergy to certain ingredients in the new food, which can cause vomiting and other digestive issues.
- Eating too much too quickly: If a dog eats a large amount of new food all at once, it may cause them to vomit. This is especially true if the food is rich or high in fat.
- Eating spoiled or contaminated food: If the new food is spoiled or contaminated, it can cause vomiting and other digestive problems.
If your dog vomits after eating new food, it’s important to monitor them closely and contact your veterinarian if the vomiting persists or if your dog becomes lethargic or appears to be in distress.

Bacterial and viral infections
Bacterial infections may cause vomiting by damaging the lining of the digestive tract or by releasing toxins that affect the functioning of the digestive system. Some types of bacteria that can cause vomiting in dogs include Salmonella, E. coli, and Clostridium.
Viral infections may also cause vomiting in dogs by damaging the digestive tract or by causing inflammation and irritation in the digestive system. Some types of viruses that can cause vomiting in dogs include parvovirus, distemper, and canine adenovirus. It is important to note that there are many other causes of vomiting in dogs besides bacterial and viral infections.
dietary intolerance or food allergy
Intolerance or food allergy can cause vomiting in dogs due to an adverse reaction to a particular ingredient or component in their diet. This can be triggered by a variety of factors, including the type of food being consumed, the presence of certain additives or preservatives, or the individual dog’s unique susceptibility to certain ingredients.
Symptoms of food intolerance or allergy in dogs can include vomiting, diarrhea, abdominal pain, and lethargy. If your dog is experiencing these symptoms, it is important to consult with a veterinarian to determine the cause and appropriate treatment.
In some cases, a dietary change may be necessary to resolve the issue. Your veterinarian may recommend switching to a hypoallergenic or limited-ingredient diet or eliminating specific ingredients from your dog’s diet. It is important to follow your veterinarian’s recommendations and to make any dietary changes gradually to minimize the risk of further digestive upset. Which can cause an allergic reaction that leads to vomiting.
Gastrointestinal problems
Gastrointestinal problems can cause vomiting in dogs for a variety of reasons. Some common causes of gastrointestinal problems that can lead to vomiting in dogs include:
- Infections: Dogs can get infections in their digestive tract from consuming contaminated food or water, or from coming into contact with infected animals. These infections can cause inflammation and irritation in the digestive tract, leading to vomiting.
- Intestinal blockages: Dogs can sometimes swallow objects that get stuck in their digestive tract, causing an intestinal blockage. This can lead to vomiting as the body tries to get rid of the blockage.
- Inflammatory bowel disease (IBD): IBD is a condition that causes inflammation in the digestive tract. This can lead to vomiting as well as diarrhea, weight loss, and poor appetite.
- Pancreatitis: Pancreatitis is a condition in which the pancreas becomes inflamed. This can lead to vomiting and abdominal pain in dogs.
- Food allergies or sensitivities: Some dogs may have allergies or sensitivities to certain types of food, which can lead to vomiting and other digestive problems.
If your dog is experiencing vomiting, it is important to consult a veterinarian for a proper diagnosis and treatment plan. Motion sickness can cause dogs to vomit after traveling or riding in a car.
Kidney Failure
Kidney failure, also known as renal failure, is a serious condition that can occur in dogs when the kidneys are no longer able to function properly. When the kidneys fail, they are unable to filter waste products from the blood, leading to a buildup of toxins in the body and leads to vomiting.
Vomiting is a common symptom of kidney failure in dogs because the toxins that accumulate in the body can irritate the stomach and cause nausea. If you suspect that your dog may be suffering from kidney failure, it is important to seek veterinary care as soon as possible. Early treatment can help to slow the progression of the disease and improve your dog’s quality of life. Treatment may include medications to control symptoms, special diets, and, in some cases, dialysis or kidney transplant.
Liver Failure | Dog Vomiting
Liver failure in dogs can cause vomiting because the liver plays a vital role in digestion and metabolism. When the liver is not functioning properly, it can disrupt the normal digestive process and lead to the build-up of toxins in the body, which can cause vomiting. Other symptoms of liver failure in dogs may include loss of appetite, weight loss, abdominal pain, diarrhea, and jaundice (yellowing of the skin and whites of the eyes).
Pancreatitis | Dog Vomiting
Pancreatitis is a condition in which the pancreas, an organ located in the abdomen, becomes inflamed. Vomiting is a common symptom of pancreatitis in dogs because the inflammation of the pancreas can cause the digestive system to become disrupted. When the pancreas is inflamed, it may produce enzymes that irritate the lining of the small intestine, leading to nausea and vomiting. The inflammation may also cause the release of toxins that can lead to vomiting. Other symptoms of pancreatitis in dogs may include abdominal pain, loss of appetite, diarrhea, and lethargy.
Cancer | Dog Vomiting
Cancer can cause sudden vomiting in dogs if the cancer is located in or has spread to the digestive system. Some types of cancer that can cause vomiting in dogs include:
- Gastrointestinal tumors: Tumors in the stomach, small intestine, or colon can cause vomiting due to blockages or irritation of the digestive system.
- Pancreatic cancer: Cancer of the pancreas can cause vomiting and other digestive symptoms such as diarrhea, loss of appetite, and weight loss.
- Liver cancer: Tumors in the liver can cause vomiting due to the liver’s role in filtering toxins from the blood.
- Lymphoma: This type of cancer affects the immune system and can cause vomiting due to inflammation in the digestive system.
Constipation | Dog Vomiting
Constipation in dogs can cause vomiting for a few reasons. First, when a dog is constipated, it may strain and exert pressure on its abdominal muscles while trying to defecate, which can lead to vomiting. This can be especially true if the constipation is severe and the dog has been unable to pass any stool for an extended time.
In addition, constipation can cause a build-up of gas in the intestine, which can lead to bloating and discomfort. This bloating can also put pressure on the stomach, leading to vomiting.
Finally, constipation can be a sign of an underlying medical condition, such as an intestinal blockage or a gastrointestinal disorder. If the constipation is caused by one of these conditions, the dog will likely experience other symptoms in addition to vomiting, such as loss of appetite, laziness, and abdominal pain.
Parvovirus | Dog Vomiting
Parvovirus is a highly contagious viral disease that can affect dogs of all ages, but it is most commonly seen in puppies. The virus attacks the intestinal tract and causes severe vomiting and diarrhea. It can also attack the heart muscle in young puppies and cause life-threatening heart problems.
The virus is shed in the feces of infected dogs and is transmitted through direct contact with the feces of an infected dog or contaminated surfaces, such as kennel floors, food and water bowls, and shoes. The virus can also be transmitted through the air, so a dog can become infected simply by being in the same room as an infected dog.
Vomiting is one of the most common symptoms of parvovirus in dogs. In addition to vomiting, dogs with parvovirus may also have diarrhea, loss of appetite, weight loss, lethargy, and fever. If left untreated, parvovirus can be fatal, especially in young puppies.
Heatstroke | Dog Vomiting
Heatstroke can cause vomiting in dogs as a result of the body’s attempts to cool itself down. When a dog’s body temperature rises too high, it can cause the body to become stressed and overwhelmed. The dog’s body may try to cool itself down by panting and sweating, but if these efforts are not sufficient, the body may also try to eliminate excess heat by vomiting. This can be a sign that the dog’s body is in distress and is trying to regulate its temperature.
Causes of Chronic Dog Vomiting
Stress and Anxiety
Stress and anxiety can indeed cause chronic vomiting in dogs. They can affect a dog’s digestive system, leading to symptoms such as vomiting, diarrhea, loss of appetite, and weight loss. Anxiety can be caused by a variety of things, including changes in the dog’s environment, separation from their owner, loud noises, and other types of stressors.
If your dog is vomiting due to stress or anxiety, it is important to try to identify and address the underlying cause. This may involve providing a more stable and predictable environment for your dog, using behavior modification techniques to address specific fears or phobias, and using medications or other therapeutic interventions as needed.
Dehydration
Dehydration in dogs can lead to long-term vomiting for several reasons. When a dog becomes dehydrated, their body does not have enough fluid to function properly, which can lead to a variety of problems.
One possible reason for vomiting in a dehydrated dog is that the body is trying to get rid of excess stomach acid. When a dog becomes dehydrated, their body may produce more stomach acid to conserve fluids. This can irritate the lining of the stomach and cause vomiting.
Another possible reason for vomiting in a dehydrated dog is that the body is trying to get rid of toxins or foreign substances that may be present in the digestive system. This is a natural response of the body to protect itself from harmful substances.
Weight loss
Chronic vomiting in dogs can cause weight loss for several reasons. Decreasing appetite resulting from vomiting can cause a reduction in the amount of food consumed, leading to a decrease in weight. Additionally, vomiting can lead to the loss of important nutrients that are important for maintaining a healthy weight, such as proteins, carbohydrates, and fats. Finally, chronic vomiting can cause dehydration, which can also contribute to weight loss.
Abdominal Pain
Dogs can experience abdominal pain due to gastrointestinal issues, infections, organ problems, and even cancer. When a dog is experiencing abdominal pain, it may vomit as a result. Vomiting can also be a symptom of the underlying condition causing abdominal pain. If your dog is experiencing chronic vomiting and abdominal pain, it is important to consult with a veterinarian.
Poor appetite
Chronic vomiting can lead to a decrease in appetite in dogs for several reasons. First, vomiting can cause nausea and discomfort in dogs, which can reduce their desire to eat. When a dog is feeling sick, it may not want to eat anything, even if they are hungry.
Second, vomiting can lead to electrolyte imbalances and dehydration, which can also decrease appetite. Dehydrated dogs may not feel like eating, and electrolyte imbalances can affect their body’s ability to properly digest and absorb nutrients from food.
Finally, chronic vomiting can cause weight loss and malnutrition, which can further decrease appetite. If a dog is losing weight and not getting enough nutrients from their food, it may not feel as hungry as it normally would.
Fever
Vomiting can be a symptom of various underlying health conditions in dogs, some of which can cause fever. For example, if a dog has an infection, such as a bacterial or viral infection, it may experience vomiting as well as an elevated body temperature (fever). Other potential causes of vomiting and fever in dogs include pancreatitis, which is inflammation of the pancreas, and gastric dilatation and volvulus (GDV), which is a condition in which the stomach becomes distended and twisted.
How can I determine whether my dog’s vomiting is serious or not?
It can be difficult to determine whether your dog’s vomiting is serious or not without further information. Here are a few things to consider when determining whether your dog’s vomiting is cause for concern:
- Frequency: If your dog is vomiting frequently or if the vomiting persists for more than a day or two, it could be a sign of a more serious issue and you should consult your veterinarian.
- The appearance of vomit: The appearance of the vomit can be a helpful indicator of the cause. For example, vomit that is yellow or greenish may indicate the presence of bile, which could be a sign of an underlying issue such as an obstruction or pancreatitis. Vomit that contains blood or looks like coffee grounds may also be a cause for concern.
- Other symptoms: If your dog is showing other symptoms in addition to vomiting, such as diarrhea, loss of appetite, lethargy, or abdominal pain, it may be a sign of a more serious issue.
Diagnosing Vomiting in Dogs
A wide variety of underlying conditions can cause vomiting in dogs, ranging from minor to serious. To determine the cause of vomiting, a vet will start by taking a thorough history of the animal, including information about its diet, any medications it is taking, and changes in its environment. They will also perform a physical examination, including checking the dog’s vital signs, examining its abdomen, and looking for any signs of illness or distress.
If the cause of the vomiting is not apparent, the veterinarian may recommend diagnostic tests to help find out the underlying problem. These tests may include blood work to check for infections, and organ dysfunction, imaging studies such as x-rays or ultrasounds to look for structural abnormalities or foreign objects, endoscopic procedures, and intestines.
It is important to consult a veterinarian as soon as possible if your dog is vomiting, as the underlying cause may be serious and prompt treatment may be necessary to ensure the best possible outcome.
Treating Vomiting in Dogs
Varying causes, such as eating something toxic, an infection, or a digestive issue, can trigger vomiting. It is important to determine the cause of the vomiting to properly treat it. Here are some general steps you can take to help treat vomiting in dogs:
- Remove food and water for a short period: It can help give the digestive system a rest and allow the vomiting to resolve. This is especially important if the vomiting is due to something the dog ate.
- Offer small amounts of water: After some time without food and water, start by offering small amounts of water. If the dog can keep the water down, you can gradually increase the amount.
- Introduce a bland diet: If the dog can keep water down, you can try introducing a bland diet. A bland diet consists of a simple, easily digestible protein (such as boiled chicken) mixed with a carbohydrate ( boiled potatoes). Offer small amounts of the bland diet every few hours to see how the dog tolerates it.
- Consult a veterinarian: If the vomiting persists, it is important to consult a veterinarian. They will be able to determine the cause of the vomiting and provide proper treatment.
