Dog Pooping Blood And Vomiting: Do You Need To Worry?

Dog pooping blood and vomiting

Dog pooping blood and vomiting can be a cause of worry for pet owners – and they should be. These symptoms can indicate serious underlying health issues, although they may not always be life-threatening. It is essential to promptly identify the cause of these symptoms and seek veterinary care to ensure proper treatment and management.


Causes of Bloody Diarrhea and Vomiting in Dogs

There are various reasons why a dog may develop bloody diarrhea and vomiting, and the severity of the symptoms can vary depending on the cause. Some of the most common causes of these symptoms in dogs are:

  1. Parasites: Parasites such as hookworms, whipworms, roundworms, and coccidia can cause bloody diarrhea and vomiting in dogs. These parasites can cause inflammation and damage to the intestinal tract, leading to bleeding and discomfort.
  2. Bacterial infections: Bacterial infections, such as Salmonella, E. coli, and Campylobacter, can cause bloody diarrhea and vomiting in dogs. These infections can be contracted through contaminated food or water sources or exposure to infected animals.
  3. Viral infections: Viral infections, such as parvovirus, coronavirus, and distemper, can cause bloody diarrhea and vomiting in dogs. These infections are highly contagious and can spread rapidly, especially in environments with many dogs.
  4. Dietary indiscretion: Eating inappropriate foods or consuming toxic substances can cause bloody diarrhea and vomiting in dogs. This condition is commonly referred to as “garbage gut” or “dietary indiscretion.”
  5. Inflammatory bowel disease (IBD): IBD is a chronic condition characterized by inflammation of the intestinal tract. This condition can cause bloody diarrhea, vomiting, and weight loss in dogs.
  6. Cancer: Cancer can cause bloody diarrhea and vomiting in dogs. The most common type of cancer affecting dogs’ digestive system is lymphoma.
  7. Hemorrhagic gastroenteritis (HGE): HGE is a condition characterized by sudden onset vomiting and bloody diarrhea. This condition can be severe and potentially life-threatening; immediate veterinary care is necessary.


Do You Need To Worry?

If your dog is pooping blood and vomiting, it is a concerning symptom that requires prompt veterinary attention. Bloody diarrhea and vomiting can indicate a serious underlying condition that requires immediate treatment. These conditions can lead to dehydration, malnutrition, and other serious health complications without proper treatment.

Not all cases of bloody diarrhea and vomiting in dogs are life-threatening, some may only require supportive care and symptomatic treatment. However, it is best to err on the side of caution and seek veterinary care as soon as possible to determine the underlying cause and provide appropriate treatment.


Diagnosis and Treatment for Bloody Diarrhea and Vomiting

When a dog presents with bloody diarrhea and vomiting, the veterinarian will perform a thorough physical examination and may recommend additional diagnostic tests to identify the underlying cause. These tests may include blood work, fecal analysis, and imaging studies such as X-rays or ultrasounds.

Treatment for bloody diarrhea and vomiting in dogs will depend on the underlying cause. In cases of parasitic or bacterial infections, the veterinarian may prescribe antibiotics or antiparasitic medication to eliminate the infection. In cases of viral infections, supportive care, such as IV fluids and medication to control vomiting, may be necessary.

Dietary changes, such as a bland diet, may be recommended for dogs with dietary indiscretion or IBD. In more severe cases of IBD, medication to reduce inflammation may be necessary. Dogs with cancer may require chemotherapy or surgery, depending on the type and location of cancer.

In cases of HGE, immediate veterinary care is necessary. Treatment for HGE typically involves hospitalization, IV fluids, and medication to control vomiting and diarrhea.


Prevention Tips

  • Practice Good Hygiene

Maintaining good hygiene is essential to prevent infections that can cause diarrhea and vomiting. Make sure to clean your dog’s living area regularly, including their bed, toys, and food and water bowls. Additionally, always wash your hands thoroughly with soap and water after handling your dog or their belongings.

  • Avoid Table Scraps and Human Foods

Feeding your dog table scraps or human foods can increase their risk of developing dietary indiscretion, which can cause vomiting and diarrhea. Avoid feeding your dog foods that are toxic to dogs, such as chocolate, onions, garlic, grapes, and raisins.

  • Monitor Your Dog’s Diet

Make sure to monitor your dog’s diet and avoid sudden changes that can upset their digestive system. Gradually introduce new foods and make sure to provide a well-balanced diet that meets their nutritional needs. Additionally, provide plenty of fresh water to keep your dog hydrated and help prevent constipation.

  • Regularly Deworm Your Dog

Parasitic infections, such as hookworms and roundworms, can cause bloody diarrhea and vomiting in dogs. Make sure to regularly deworm your dog as recommended by your veterinarian. Additionally, keep your dog away from areas where other dogs defecate, as these areas can harbor parasites.

  • Keep Your Dog Up-to-Date on Vaccinations

Viral infections, such as parvovirus and distemper, can cause bloody diarrhea and vomiting in dogs. Make sure to keep your dog up-to-date on their vaccinations to prevent these infections. Consult with your veterinarian to determine the appropriate vaccination schedule for your dog.

  • Supervise Your Dog Outdoors

Supervising your dog while they are outside can help prevent them from eating toxic substances, such as garbage or toxic plants. Additionally, make sure to keep potentially harmful household items, such as cleaning products and medications, out of your dog’s reach.



In conclusion, bloody diarrhea and vomiting are concerning symptoms in dogs that can indicate serious underlying health issues. Identifying the underlying cause promptly and seeking veterinary care is essential to ensure proper treatment and management. There are also simple steps to help these symptoms such as good hygiene, monitoring your dog’s diet, regular deworming, and updating your dog’s vaccination.
