why would a dog throw up blood

Dog owners often experience their canines vomiting from time to time. However, when a dog begins to throw up blood, it can be a cause for concern. Hematemesis, the medical term for bloody vomit, can be a symptom of various health issues in dogs. It is essential to understand the potential causes and seek veterinary care promptly.

Gut health is crucial to a dog’s overall well-being. Healthy gut bacteria help maintain a strong gut lining that prevents holes in the gut, which can result in bloody vomit. Therefore, including good dog probiotic supplements as part of a dog’s daily care can prevent hematemesis (bloody vomit). To provide pet parents with the best possible advice, we consulted expert veterinary sources to give a complete answer to this question.

If a dog throws up blood, it’s important to seek veterinary care immediately. The vet will conduct a thorough examination and may recommend diagnostic tests such as blood work, x-rays, or a fecal exam to determine the underlying cause of the vomiting.

Treatment will depend on the underlying cause of the vomiting. In some cases, the vet may recommend medication to treat an infection or parasite. In other cases, surgery may be necessary to remove an obstruction or tumor. In all cases, it’s important to follow the vet’s instructions carefully to ensure a full recovery.

Understanding Canine Hematemesis

When a dog throws up blood, it can be a concerning and alarming experience for any pet owner. Hematemesis, or vomiting blood, can be caused by a variety of factors, ranging from minor irritation to more serious medical conditions.

To understand hematemesis and its potential causes, it’s important to have a basic understanding of canine gut anatomy. The gastrointestinal (GI) tract consists of various organs, including the esophagus, stomach, small intestine, and large intestine. 

The lining of the GI tract is composed of several layers, including the mucosa, submucosa, muscularis, and serosa. The mucosa layer is the innermost layer that comes into contact with food and is responsible for absorbing nutrients.

One potential cause of hematemesis is damage to the gut lining. This can occur due to a variety of factors, including infection, inflammation, or ingestion of a foreign object. When the gut lining is damaged, it can lead to the formation of holes, or ulcers, which can bleed and cause blood to appear in vomit.

The appearance and color of the blood in the vomit is very important in determining the potential cause of hematemesis. In fact, it’s vital to take a picture or collect a sample of any bloody dog vomit for your dog to see.

In some cases, hematemesis can be a sign of a more serious medical condition, such as liver disease, kidney disease, or cancer. If a pet owner notices blood in their dog’s vomit, it’s important to seek veterinary attention immediately.

Here is a table summarizing the different types of blood in vomit and their potential causes:

Type of BloodAppearancePotential Cause
Bright red, liquid blood in vomitFresh bloodEsophageal bleeding
Dark red, clotted, or coffee ground-like blood in dog vomitPartially digestedStomach or upper intestinal bleeding
Foamy and pink-tinged or has small specks of blood in dog vomitIrritationLess serious than other scenarios

Coughing Up Blood Vs. Throwing Up Blood In Dogs

It’s important to note that throwing up blood and coughing up blood are two different things and can have different underlying causes.

Coughing up blood in dogs can be a sign of respiratory issues such as pneumonia, lung cancer, or kennel cough. Dogs coughing usually stretch out their neck and make a honking noise. This can lead to gagging, which can sound a lot like vomiting, but it’s really blood coming up from the lungs, not the stomach.

Other symptoms of respiratory issues can include difficulty breathing, wheezing, and lethargy.

On the other hand, throwing up blood in dogs can be a sign of gastrointestinal issues such as stomach ulcers, parvo, ingestion of foreign objects, or pancreatitis. Dogs may also experience vomiting, diarrhea, pale gums, and loss of appetite alongside throwing up blood.

It’s important to note that both coughing up blood and throwing up blood in dogs require immediate veterinary attention. A veterinarian can perform diagnostic tests and determine the underlying cause of the symptoms.

Common Causes of Dogs Vomiting Blood

1. Stomach Ulcers

Stomach ulcers can be a cause of vomiting blood in dogs. Ulcers are open sores that develop on the lining of the stomach or intestines, and they can be caused by a variety of factors, including stress, medications, infections, and more.

Symptoms of stomach ulcers in dogs can include vomiting, abdominal pain, loss of appetite, and weight loss. In some cases, dogs may also have black, tarry stools, which can indicate bleeding in the stomach or intestines.

Diagnosis of stomach ulcers in dogs typically involves a combination of physical examination, blood tests, and imaging studies such as X-rays or ultrasound. Treatment may include medications such as proton pump inhibitors or antibiotics, as well as changes to the dog’s diet and lifestyle to reduce stress and promote healing.

It’s important to note that while stomach ulcers can be a serious condition, they are treatable with appropriate veterinary care. If you suspect that your dog may be suffering from stomach ulcers, it’s important to seek veterinary attention promptly to ensure that your dog receives the care they need.

2. Internal Parasites

If your dog is throwing up blood, parasites like hookworms, roundworms, or whipworms could be the culprit. These nasty critters latch onto the insides of your dog’s intestines and start feeding off their blood and nutrients. Think of them like unwanted house guests that raid your fridge and then leave a mess behind!

This “mess” in your dog’s intestines can get irritated and even bleed. When that happens, your dog might throw up blood. Sometimes the blood might look fresh and red, or it might appear dark and digested, depending on how long it’s been in the stomach.

Either way, this is a red flag that you shouldn’t ignore. Parasites not only cause this immediate issue, but they also make your dog weaker over time by stealing essential nutrients. This can even lead to anemia, which is another reason you might see blood.

3. Obstruction in Esophagus, Throat Or Gut

If a dog throws up blood, it could be due to an obstruction in their esophagus, throat, or gut. This obstruction could be caused by a foreign object, such as a bone or toy, that the dog has swallowed. It could also be caused by a tumor or growth in the throat or gut.

If the obstruction is in the esophagus, the dog may have difficulty swallowing and may regurgitate food or water. If the obstruction is in the throat or gut, the dog may have difficulty breathing, may vomit frequently, and may have diarrhea.

If a dog is suspected of having an obstruction, it is important to seek veterinary care immediately. The veterinarian may need to perform X-rays, ultrasound, or endoscopy to locate and remove the obstruction.

4. Hemorrhagic gastroenteritis (HGE) & Gastritis

Hemorrhagic Gastroenteritis (HGE) is a condition that causes acute vomiting and bloody diarrhea in dogs. The exact cause of HGE is unknown, but it is believed to be related to stress, diet, and bacterial infections. HGE can occur in dogs of any age, breed, or gender, but it is more common in small breeds, such as the Miniature Schnauzer.

Gastritis, on the other hand, is the inflammation of the stomach lining, which can also cause vomiting and bloody diarrhea in dogs. Gastritis can be caused by a variety of factors, including stress, diet, and bacterial infections.

The symptoms of HGE and gastritis are similar and can include vomiting, diarrhea, lethargy, loss of appetite, and dehydration. It is important to note that both conditions can be life-threatening if left untreated.

Treatment for HGE and gastritis typically involves hospitalization, intravenous fluids, antibiotics, and anti-vomiting medication. In severe cases, a blood transfusion may be necessary.

5. Viral & Bacterial Infections (Parvovirus)

Parvovirus is a highly contagious virus that can cause bloody vomiting and diarrhea in dogs. Puppies are especially vulnerable to the virus, and it can be fatal if left untreated. Other symptoms of parvovirus include lethargy, loss of appetite, and fever.

The virus is spread through contact with infected feces, and it can survive in the environment for months. Dogs that have not been vaccinated against parvovirus are at a higher risk of contracting the virus.

Treatment for parvovirus usually involves hospitalization, intravenous fluids, and antibiotics to prevent secondary infections. Recovery can take several days to weeks, and it is important to follow up with your veterinarian to ensure that your dog has fully recovered.

In addition to parvovirus, other viral and bacterial infections can also cause bloody vomiting in dogs. 

In people, a bacteria called Helicobacter pylori is known to cause stomach issues like ulcers and gastritis. But when it comes to our pets, like dogs and cats, the situation is a bit more complicated. These critters also have Helicobacter bacteria in their stomachs, but it’s not so clear-cut that the bacteria actually make them sick.

6. Certain Medications (NSAIDs)

You know those meds you give your dog for pain or swelling, called NSAIDs? They’re super common and usually do the trick for aches and pains. But here’s the catch: Veterinary Nonsteroidal Anti-Inflammatory Drugs (NSAIDs) can mess with your dog’s tummy and sometimes even make them throw up blood.

These meds work by blocking stuff in the body that causes pain and inflammation. But that same stuff also helps protect your dog’s stomach lining. So when you block it, you might end up with an upset stomach, ulcers, or even bleeding.

Some newer NSAIDs are supposed to be easier on the stomach, but the truth is, there’s still a risk. Side effects can be nasty, from stomach issues to liver and kidney problems, and in really bad cases, they can even be fatal.

If your dog starts throwing up blood while on these meds, hit the brakes and get them to the vet, stat. Your vet will likely suggest different ways to manage pain or might tweak the dosage. But don’t try to manage this at home—always consult a pro for something this serious.

7. Cancers

When your dog has a belly tumor like lymphoma or other types with hard-to-pronounce names, it can create ulcers or sores in their stomach. Basically, the tumor messes up the local area and can cause bleeding and other issues.

Some specific types of tumors, like mast cell tumors, can even ramp up stomach acid levels. This makes the situation worse because the extra acid can lead to more ulcers or sores in the stomach. It’s kind of like these tumors have a ‘double-whammy’ effect on your dog’s tummy.

Here’s a quick rundown of some of the different types of stomach-related cancers in dogs, made simple:

  1. Lymphoma: This is a cancer of the lymph nodes, but it can also show up in the stomach and cause ulcers or sores.
  2. Adenocarcinoma: This is a fancy term for a tumor that starts in the glands of the stomach lining and can spread quickly.
  3. Leiomyoma: This is a usually non-cancerous tumor that comes from the smooth muscle layer of the stomach, but it can still cause problems like ulcers.
  4. Leiomyosarcoma: Similar to Leiomyoma but it’s the malignant or “bad guy” version that spreads and can cause a lot of internal damage.
  5. Mast Cell Tumors: These are skin tumors that can actually mess with the stomach by ramping up stomach acid levels.
  6. Gastrinomas (Zollinger-Ellison Syndrome): Very rare, but these tumors increase stomach acid, leading to ulcers and digestive issues.

If cancer is suspected, treatment options may include surgery, chemotherapy, or radiation therapy. The best course of treatment will depend on the type and stage of the cancer, as well as the overall health of the dog.

8. Inflammatory Bowel Syndrome

Inflammatory Bowel Syndrome (IBS) is a chronic condition that affects the digestive system. It is characterized by inflammation of the lining of the intestines, which can lead to a variety of symptoms, including vomiting blood.

The exact cause of IBS is not known, but it is thought to be a combination of genetic and environmental factors. Some of the common risk factors for IBS include stress, diet, and infections.

Symptoms of IBS can vary from person to person, but may include abdominal pain, diarrhea, constipation, and bloating. In some cases, vomiting blood may also occur.

Treatment for IBS typically involves a combination of dietary changes, medication, and stress management techniques. In some cases, surgery may be necessary.

If your dog is experiencing symptoms of IBS, it is important to consult with a veterinarian for an accurate diagnosis and appropriate treatment plan.

9. Liver Disorders

Liver disorders can also be a reason for vomiting blood in dogs as they seem to cause stomach ulcers. The liver is an essential organ that helps in processing food and removing toxins from the body. When the liver is not functioning correctly, it can lead to various health problems, including vomiting blood.

One of the most common liver disorders in dogs is hepatitis. Hepatitis is an inflammation of the liver that can be caused by various factors, including infections, toxins, and autoimmune diseases. Dogs with hepatitis may show symptoms such as vomiting, diarrhea, lethargy, and loss of appetite. In severe cases, hepatitis can lead to liver failure and death.

Another liver disorder that can cause vomiting blood in dogs is liver cancer. Liver cancer can develop from the liver cells or spread from other parts of the body. Dogs with liver cancer may show symptoms such as vomiting, weight loss, and abdominal pain. In some cases, liver cancer can be treated with surgery or chemotherapy.

Finally, intrahepatic portosystemic shunt (IHPSS) is another liver disorder that can cause vomiting blood in dogs. IHPSS is a congenital condition where the blood vessels in the liver do not develop correctly, leading to abnormal blood flow. This can cause a buildup of toxins in the body, leading to symptoms such as vomiting, seizures, and behavioral changes. Treatment for IHPSS may include surgery or medication to manage symptoms.

10. Poisons & Toxins That Can Cause A Dog To Vomit Blood

A dog may throw up blood due to various reasons, including poisons and toxins. Some of the common poisons and toxins that can cause a dog to vomit blood are:

1. Rat Poison

Rat poison is one of the most common poisons that can cause a dog to vomit blood. Rat poison contains anticoagulants that prevent blood from clotting, leading to internal bleeding. If a dog ingests rat poison, they may show symptoms such as vomiting, lethargy, pale gums, and difficulty breathing.

2. Human Medications

Human medications such as aspirin, ibuprofen, and acetaminophen can be toxic to dogs. These medications can cause stomach ulcers, internal bleeding, and other health problems that may result in vomiting blood.

3. Toxic Foods

Certain foods such as chocolate, grapes, raisins, onions, and garlic can be toxic to dogs. These foods can cause stomach upset, internal bleeding, and other health problems that may result in vomiting blood.

4. Household Chemicals

Household chemicals such as cleaning products, pesticides, and fertilizers can be toxic to dogs if ingested. These chemicals can cause stomach upset, internal bleeding, and other health problems that may result in vomiting blood.

It is essential to keep these poisons and toxins away from your dog’s reach. If you suspect that your dog has ingested any of these substances, you should immediately contact your veterinarian. Early diagnosis and treatment can help prevent serious health problems and save your dog’s life.

11. Pancreatitis

Pancreatitis is a condition that occurs when the pancreas becomes inflamed. This can happen due to a variety of reasons, including high-fat diets, obesity, and certain medications. Dogs with pancreatitis often experience vomiting, diarrhea, and abdominal pain. In severe cases, they may also vomit blood.

Pancreatitis can be diagnosed through blood tests, ultrasound, and other imaging techniques. Treatment typically involves hospitalization, fluid therapy, and medications to manage pain and inflammation. In some cases, surgery may be necessary to remove damaged tissue from the pancreas.

Prevention is key when it comes to pancreatitis. Owners should avoid feeding their dogs high-fat diets and ensure that they maintain a healthy weight. Regular exercise and routine veterinary check-ups can also help prevent pancreatitis.

12. Extreme Exercise

Studies show that diarrhea and stomach ulcers are quite common in dogs that are involved in extreme exercise, like sled dogs. This is because intense physical activity can lead to a condition called exercise-induced gastric hemorrhage (EIGH) and is linked to gastritis in working dogs.

EIGH is a condition that occurs when the lining of a dog’s stomach ruptures due to the strain of intense exercise. Stomach inflammation connected to excessive exercise also seems to lead to more ulcers in working and racing dogs.

EIGH (and exercise-induced pulmonary hemorrhage)  is more common in greyhounds and other breeds that are bred for racing, but it can happen to any dog that engages in intense exercise. The condition is more likely to occur in dogs that are not used to regular exercise or are not in good physical condition. Also, stomach ulcers seem to happen more often in working dog breeds than any other dog or mixed breed.

13. Kidney Diseases

Kidney diseases are a common cause of vomiting blood in dogs. The kidneys play a vital role in filtering waste products from the blood and regulating the balance of fluids and electrolytes in the body. When the kidneys are not functioning properly, waste products can build up in the blood, leading to vomiting and other symptoms.

There are several types of kidney diseases that can cause a dog to vomit blood, including:

  • Acute kidney injury: This occurs when the kidneys suddenly stop working properly, often due to a toxin or infection.
  • Chronic kidney disease: This is a long-term condition where the kidneys gradually lose function over time, often due to aging or underlying health conditions.
  • Glomerulonephritis: This is an inflammation of the glomeruli, the tiny blood vessels in the kidneys that filter waste products from the blood.
  • Pyelonephritis: This is a bacterial infection of the kidneys that can cause inflammation and damage.

Symptoms of kidney disease in dogs may include vomiting, diarrhea, loss of appetite, weight loss, increased thirst and urination, and lethargy. Treatment for kidney disease may include medications to manage symptoms, dietary changes, and in severe cases, dialysis or kidney transplantation.

It is important to seek veterinary care if a dog is vomiting blood, as kidney disease can be a serious and potentially life-threatening condition if left untreated.

14. Spinal Disease

Spinal diseases can also cause a dog to throw up blood. The most common spinal disease that leads to vomiting blood is intervertebral disc disease (IVDD). IVDD is a condition where the discs between the vertebrae in a dog’s spine degenerate or herniate, causing pressure on the spinal cord. This pressure can lead to vomiting, as well as other symptoms such as back pain, paralysis, and loss of bladder and bowel control.

Other spinal diseases that can cause a dog to throw up blood include spinal tumors and infections. Spinal tumors can be either primary (originating in the spine) or metastatic (spreading from other parts of the body). Infections of the spinal cord, such as meningitis, can also cause vomiting blood, as well as other symptoms such as fever, lethargy, and neck pain.

15. Major Injury or Trauma

Dogs can throw up blood due to major injury or trauma. Injuries to the gastrointestinal tract or other internal organs can cause internal bleeding, which may result in vomiting blood. Trauma to the head or abdomen can also cause vomiting of blood.

In some cases, dogs may ingest foreign objects that can cause internal injuries. Sharp objects such as bones or needles can puncture the stomach or intestines, causing internal bleeding. Dogs may also suffer from blunt force trauma, such as being hit by a car or falling from a height, which can cause internal injuries.

If a dog has suffered a major injury or trauma and is vomiting blood, it is important to seek immediate veterinary attention. Treatment may involve surgery to repair internal injuries or blood transfusions to replace lost blood. In some cases, the dog may need to be hospitalized for 

16. Swallowing Blood From Mouth Or Throat

Dogs may throw up blood due to various reasons, including swallowing blood from their mouth or throat. This can happen if the dog has an injury or irritation in their mouth or throat, such as a cut, ulcer, or foreign object.

When a dog swallows blood from their mouth or throat, it can cause irritation and inflammation in their digestive tract, leading to vomiting. The blood may also cause the dog to feel nauseous, which can trigger vomiting as well.

17. Sepsis

Sepsis is a severe and potentially life-threatening condition that occurs when the body’s response to infection causes inflammation throughout the body. This inflammation can cause damage to organs and tissues and can lead to septic shock, a medical emergency.

In dogs, sepsis can occur as a result of a bacterial infection, such as a urinary tract infection or pneumonia. It can also be caused by a fungal or viral infection.

Symptoms of sepsis in dogs include vomiting, diarrhea, lethargy, loss of appetite, fever, and rapid breathing. In severe cases, dogs may also experience seizures, organ failure, and coma.

If a dog is vomiting blood and is suspected to have sepsis, immediate medical attention is necessary. Treatment may include antibiotics, fluids, and supportive care to manage symptoms and prevent complications.

It is important to note that while sepsis can be a serious condition, prompt diagnosis and treatment can greatly improve a dog’s chances of recovery.

Symptoms Accompanying Blood in Vomit

If you notice your dog vomiting blood, it’s a red flag that you should get to the vet ASAP. But there might be other symptoms that could tip you off that something’s not right. Here’s a quick checklist of things to watch for:

  1. Lethargy: If your dog’s energy level suddenly drops, that’s a warning sign.
  2. Loss of Appetite: Not interested in food? That’s another clue something might be off.
  3. Diarrhea or Bloody Stools: Any changes in their poop, especially blood, is a reason for concern.
  4. Abdominal Pain: If your dog seems uncomfortable, especially around their belly, it could be a sign of internal issues.
  5. Excessive Drooling: More drool than usual could indicate nausea or stomach upset.
  6. Frequent Attempts to Vomit: If they keep trying to throw up but can’t, that’s a big warning signal.
  7. Pale Gums: This could mean your dog is anemic, possibly from internal bleeding.
  8. Difficulty Breathing: If your dog seems to be having trouble breathing, it’s an emergency situation.
  9. Rapid Weight Loss: Losing weight quickly and without reason is always a vet visit waiting to happen.

If you see one or more of these symptoms along with vomiting blood, don’t wait — get to a vet for a proper diagnosis and treatment plan. It could be a sign of something serious.

Diagnosing the Issue When A Dog Vomits Blood

Veterinary Examination

If a dog is throwing up blood, it is important to take them to the veterinarian as soon as possible. The veterinarian will conduct a thorough physical examination of the dog and ask questions about the dog’s medical history and symptoms. During the physical examination, the veterinarian will look for signs of dehydration, abdominal pain, and other symptoms that may indicate the underlying cause of the vomiting.

Diagnostic Tests

After the physical examination, the veterinarian may recommend diagnostic tests to determine the underlying cause of the vomiting. These tests may include:

  • Blood tests: Blood tests can help identify any abnormalities in the dog’s blood, such as infections or organ dysfunction.
  • Urine tests: Urine tests can help identify any abnormalities in the dog’s urine, such as infections or kidney problems.
  • X-rays: X-rays can help identify any abnormalities in the dog’s abdomen, such as blockages or foreign objects.
  • Ultrasound: An ultrasound can help identify any abnormalities in the dog’s organs, such as tumors or cysts.
  • Endoscopy: Endoscopy involves inserting a small camera into the dog’s digestive tract to look for any abnormalities.

Once the underlying cause of the vomiting has been identified, the veterinarian can recommend appropriate treatment options. It is important to follow the veterinarian’s recommendations closely to ensure the dog makes a full recovery.

Treatment Options For Dogs Throwing Up Blood

Immediate Care

If a dog is throwing up blood, it is important to seek veterinary care immediately. The veterinarian will perform a physical examination and may recommend diagnostic tests such as blood work, urinalysis, and imaging studies to determine the underlying cause of the vomiting. In some cases, emergency treatment may be necessary, such as blood transfusions or surgery.

In addition to seeking veterinary care, there are some immediate care options that can be taken at home. These include:

  • Withholding food and water for 12-24 hours to allow the dog’s gastrointestinal tract to rest.
  • Offering small amounts of water or ice cubes to prevent dehydration.
  • Administering medication as directed by a veterinarian, such as anti-nausea medication or pain relief medication.

Long-Term Management

Once the underlying cause of the vomiting has been determined, long-term management can begin. Treatment options will depend on the underlying cause and may include:

  • Dietary changes, such as a prescription diet or a bland diet.
  • Medications to manage symptoms or treat the underlying condition, such as antibiotics or anti-inflammatory medications.
  • Surgery to remove an obstruction or treat a gastrointestinal disorder.
  • Chemotherapy or radiation therapy for cancer.

In addition to medical treatment, there are some lifestyle changes that can help manage vomiting in dogs, such as:

  • Feeding smaller, more frequent meals.
  • Avoiding table scraps and other foods that may be difficult for the dog to digest.
  • Providing plenty of fresh water.
  • Reducing stress and anxiety, which can exacerbate gastrointestinal issues.

Overall, the treatment options for dogs throwing up blood will depend on the underlying cause and severity of the condition. It is important to work closely with a veterinarian to determine the best course of treatment for your dog.

Prevention Strategies

Preventing a dog from throwing up blood involves taking a few measures to ensure the dog’s overall health and well-being. Here are some strategies to prevent your dog from throwing up blood:
