Types of Bloody Stool in Dogs: Hematochezia and Melena
Dogs can experience different types of bloody stool, namely hematochezia and melena. Understanding the characteristics of each type can provide valuable insights into the possible underlying causes.
Hematochezia:
Hematochezia refers to the presence of bright red blood in a dog’s stool. This typically indicates issues in the lower digestive tract or colon. Common causes of hematochezia include colitis, which is inflammation of the colon, and parasitic infections such as hookworms. Trauma, toxins, inflammatory bowel disease, and anal sac infections or impactions can also lead to hematochezia in dogs.
Severe conditions that may result in hematochezia include viral and bacterial infections, parvovirus, hemorrhagic gastroenteritis, and the possibility of cancer. Consulting with a veterinarian and conducting diagnostic tests such as fecal examinations and blood work is crucial to determine the specific cause of hematochezia.
Melena:
Melena is characterized by the presence of dark, tarry stool and typically indicates problems in the upper digestive tract. There are numerous potential causes of melena in dogs, including parasitic infections, inflammatory disorders, infections, ulcers, tumors, foreign bodies, kidney failure, exposure to toxins, Addison’s disease, liver disease, pancreatitis, hormonal imbalances, clotting disorders, and reactions to certain medications.
Please be aware that dogs experiencing melena may exhibit additional symptoms such as changes in appetite, activity levels, vomiting, diarrhea, weakness, blood in the urine, and difficulty breathing. Veterinary intervention, including diagnostic tests, is essential to determine the specific cause of melena and provide appropriate treatment.

Taking Action: Consulting a Veterinarian
If a dog exhibits bright red blood in their stool, it is crucial to consult a veterinarian. A professional evaluation will help determine the underlying cause and guide appropriate treatment. Diagnostic tests, such as fecal examinations and blood work, may be necessary to identify the specific condition causing the hematochezia. Early intervention can ensure the best possible outcome for the dog’s health and well-being.
Remember, bright red blood in a dog’s stool should never be ignored, as it can be a sign of an underlying health issue that requires attention. By promptly seeking veterinary care and following the recommended treatment plan, pet owners can help their dogs recover and enjoy a healthy life.
Common Causes of Melena in Dogs
When it comes to dark, tarry stool, known as melena, in dogs, there are several common causes that pet owners should be aware of. Melena can be a sign of underlying issues that require veterinary attention. Here are some of the most frequent culprits:
- Parasites: Certain parasites, such as hookworms, can lead to melena in dogs. These internal parasites can cause damage to the gastrointestinal tract, resulting in dark, tarry stool.
- Inflammatory disorders: Inflammation in the digestive system, such as inflammatory bowel disease, can contribute to the development of melena. These disorders often require management and treatment from a veterinarian.
- Infections: Bacterial or viral infections can cause melena in dogs. These infections may result from exposure to pathogens or contaminated food and water sources.
- Ulcers: Ulcers in the gastrointestinal tract can lead to bleeding, which can manifest as melena in dogs. Ulcers may be caused by certain medications, infections, or underlying health conditions.
- Tumors: In some cases, tumors in the digestive system can cause melena. These tumors may be benign or malignant, and appropriate diagnostic testing is necessary for proper identification.
- Kidney failure: Dogs with kidney failure may develop melena as a result of the disease’s impact on the body’s waste-processing abilities.
- Toxins: Exposure to certain toxins, such as lead or certain plants, can cause damage to the gastrointestinal tract, leading to melena in dogs.
- Other underlying health conditions: Conditions like Addison’s disease, liver disease, pancreatitis, hormonal imbalances, and clotting disorders can contribute to the development of melena.
If you notice dark, tarry stool in your dog, it is essential to consult with a veterinarian for a proper diagnosis. They will be able to determine the underlying cause of the melena and recommend an appropriate treatment plan to address the issue.
