What Are The Causes Of Blood In Dogs’ Stool?

Dietary Factors

Dietary Factors and Bloody Stool in Dogs

Diet plays a significant role in a dog’s overall health, and it can also have an impact on their stool. While some dietary changes may be beneficial, others can cause digestive issues. If your furry friend is experiencing bloody stool, it’s essential to examine their diet to identify any possible causes.

Common Causes of Dietary-Related Hematochezia

  1. Sudden diet change: Abruptly changing a dog’s diet can lead to gastrointestinal issues such as vomiting and diarrhea. These digestive problems could lead to bloody stool.

  2. Food allergies or intolerance: Some dogs may develop food allergies or intolerance to certain food ingredients, leading to inflammation in the intestinal tract that can cause blood in their stool.

  3. High-fat diets: Giving your dog a high-fat diet can cause pancreatitis, an inflammatory condition that affects the pancreas. This condition can cause hematochezia.

  4. Table scraps: Table scraps may not provide all the necessary nutrients for dogs’ well-being and can cause digestive issues such as diarrhea and bloody stool.

What You Can Do

If you suspect that your dog’s diet is causing their bloody stool, consult your veterinarian right away. Your vet will recommend dietary changes depending on the specific cause of the hematochezia. In some cases, they may suggest switching to a bland diet with easily digestible proteins and carbohydrates.

It’s crucial to introduce any dietary changes gradually to avoid further digestive issues. Always monitor your dog’s appetite, bowel movements, and overall behavior after the dietary changes. Additionally, ensure your dog gets enough hydration by providing them with clean drinking water, especially during hot weather.

In conclusion, dietary factors can contribute significantly to the development of hematochezia in dogs. By understanding what foods to avoid and making appropriate dietary changes, you can prevent recurrent bloody stool and ensure your furry friend stays healthy.

Parasites And Infections

Parasites and Infections Leading to Blood in Dogs’ Stool

Parasites and infections are common causes of bloody stool in dogs, and it’s essential to identify them early to start the treatment as soon as possible. Here are some of the parasites and infections that can cause bloody stool in dogs:

Parasites Causing Bloody Stool in Dogs

  1. Roundworms: These parasites are typically found in puppies and can cause diarrhea, vomiting, and bloody stool.
  2. Hookworms: Hookworms are more common in adult dogs and can lead to anemia and bloody diarrhea.
  3. Whipworms: Whipworms are another intestinal parasite that can cause bloody diarrhea, weight loss, and dehydration.

Infections Leading to Bloody Stool in Dogs

  1. Bacterial Infection: Bacteria like Salmonella, E. coli, and Campylobacter can cause bloody diarrhea in dogs. These bacterial infections are often contracted through contaminated food or water sources.
  2. Viral Infection: Viruses like Parvovirus can cause severe diarrhea and bloody stool in dogs. This infection is highly contagious and can be fatal if not treated promptly.

If you suspect your dog has bloody stool due to parasites or infections, contact your veterinarian immediately. They will perform a fecal analysis and prescribe appropriate medication to treat the underlying issue. Additionally, ensure to keep your dog’s environment clean and avoid feeding them contaminated food or water to prevent such infections.

Digestive System Disorders

Digestive system disorders are one of the most common causes of bloody stool in dogs. These disorders can affect various parts of the digestive tract, including the stomach, intestines, and rectum, and can lead to inflammation, irritation, or damage to the lining of these organs.

One digestive system disorder that can cause bloody stool in dogs is inflammatory bowel disease (IBD). This condition involves chronic inflammation of the digestive tract, which can result in diarrhea, vomiting, and weight loss, as well as blood in the stool. IBD can be difficult to diagnose and manage, but with proper treatment, many dogs can live happy, healthy lives.

Another digestive system disorder that can lead to bloody stool in dogs is colitis. Colitis refers to inflammation of the colon, and can be caused by a variety of factors, including infections, parasites, and stress. Symptoms of colitis can include diarrhea, abdominal pain, and blood in the stool.

Other digestive system disorders that may cause bloody stool in dogs include gastric ulcers, tumors, and polyps. In some cases, these conditions may require surgery or other invasive treatments to resolve.

If you notice blood in your dog’s stool, it’s important to seek veterinary care right away. Your vet can perform diagnostic tests to determine the underlying cause of the bleeding, and develop an appropriate treatment plan. With prompt diagnosis and treatment, many dogs with digestive system disorders can recover fully and enjoy a high quality of life.

Medications And Toxins

Medications And Toxins

Some medications and toxins can cause bloody stool in dogs. Medications like aspirin, nonsteroidal anti-inflammatory drugs (NSAIDs), and steroids can irritate the lining of a dog’s digestive tract, leading to inflammation and bleeding. Other medications that could cause bloody stool include anticoagulants, which are used to prevent blood clots, and antibiotics, which can disrupt the balance of bacteria in the gut.

Toxins such as rat poisons, household cleaners, and certain human foods can also lead to bloody stool in dogs. These substances can cause damage to the gastrointestinal tract, resulting in bleeding. Common food items that are toxic to dogs include chocolate, onions, garlic, grapes, and raisins.

It is important to keep all medications and toxic substances out of reach of pets and to follow label instructions carefully. If you suspect that your dog has ingested a toxic substance or medication, seek veterinary care immediately.

The treatment for medication and toxin-induced bloody stool will depend on the specific substance ingested and the severity of symptoms. Treatment may involve inducing vomiting, administering activated charcoal to absorb the substance, or providing supportive care such as fluids and electrolytes.

In conclusion, it is essential to be aware of the potential medications and toxins that can cause bloody stool in dogs. Taking steps to prevent exposure to these substances and seeking prompt veterinary care if ingestion occurs can help keep your furry friend healthy and happy.

Symptoms Of Blood In Dogs’ Stool

Blood in a dog’s stool can be alarming and it’s important to understand the symptoms so you can take action promptly. The medical term for blood in the stool is hematochezia, which usually appears as bright red streaks or droplets in the feces. Here are some common signs and symptoms of blood in dogs’ stool.

  • Visible Blood: As mentioned, the most obvious sign of hematochezia is visible blood in your pet’s feces. This may appear as bright red streaks or droplets, making it easy to spot.
  • Diarrhea: If your dog has diarrhea along with bloody stools, it could indicate an infection or inflammation in the digestive system.
  • Straining: If your dog is straining while trying to defecate or appears to be in pain, it may be due to rectal irritation from the blood in their stool.
  • Lethargy: Dogs with hematochezia may become lethargic and lose their appetite due to the discomfort they’re experiencing.
  • Dehydration: If your dog has been passing bloody stools for a prolonged period, they may become dehydrated, which can lead to serious health complications.

It’s important to note that blood in your dog’s stool can be a symptom of a serious underlying condition, so if you notice any of these symptoms, you should consult with your veterinarian right away. They can perform diagnostic tests to determine the underlying cause of the hematochezia and provide appropriate treatment.

Diagnosis And Treatment

Diagnostic Tests

When your furry friend is suffering from blood in their stool, it can be a scary and concerning situation. If you notice any signs of hematochezia, it’s essential to take them to the vet immediately. One of the first steps in diagnosing the underlying cause is through diagnostic tests.

Some of the commonly used diagnostic tests for bloody stool in dogs include:

  • Fecal examination: This test checks the dog’s stool for parasites, bacteria, and other abnormalities that could be causing the bleeding.
  • Blood tests: These tests help determine if the dog has anemia or an infection, which could be related to their bloody stool.
  • X-rays: X-rays of the abdominal area can help identify any foreign objects, tumors, or other obstructions that may be causing the bleeding.
  • Ultrasound: An ultrasound can help visualize the organs in the abdominal area and detect any abnormalities that may be causing the bleeding.
  • Endoscopy: During this procedure, a thin tube with a camera is inserted into the dog’s digestive tract to examine the lining and identify any areas of inflammation or damage.

It’s important to note that these diagnostic tests are not necessarily done in a particular order and may vary depending on the veterinarian’s assessment of the dog’s symptoms and medical history. The results of these tests will help the veterinarian determine the underlying cause of the blood in the stool and develop an appropriate treatment plan.

In conclusion, diagnostic tests are crucial in identifying the underlying cause of blood in dogs’ stool. It’s essential to follow the veterinarian’s recommended testing to arrive at an accurate diagnosis and receive appropriate treatment.

Treatment Options

Treatment Options for Hematochezia in Dogs

If your dog is pooping blood, it’s important to get them treated as soon as possible. The treatment options for hematochezia will depend on the underlying cause of the condition. Here are some common treatment options that your vet may prescribe:


Medications like antibiotics, antiparasitics, and anti-inflammatory drugs can be used to treat infections, parasites, and inflammatory bowel disease (IBD) that may be causing the bloody stool. For example, if your dog has a bacterial infection, your vet may prescribe antibiotics to clear up the infection.

Diet Changes

Diet plays an important role in your dog’s overall health. If dietary factors are causing the bloody stool, your vet may recommend a change in diet. They may suggest switching to a hypoallergenic or low-fat diet, or eliminating certain foods from your dog’s diet that may be causing the issue.


In rare cases, surgery may be required to treat the underlying condition causing the hematochezia. For example, if your dog has a tumor or blockage in their digestive tract, surgery may be needed to remove it.

Blood Transfusion

If your dog has lost a significant amount of blood due to the hematochezia, they may need a blood transfusion. This is a serious but potentially life-saving treatment option that can help replace the lost blood cells and restore your dog’s health.

It’s important to note that the treatment options mentioned above are not exhaustive and may vary based on your dog’s individual case. It’s crucial to work closely with your vet to determine the best course of action for your pet.

In conclusion, there are various treatment options available for hematochezia in dogs, depending on the underlying cause. Early diagnosis and treatment can help prevent more serious complications and ensure the well-being of your furry friend.
