Blood in Stool Dog: Causes & Treatment

Have you noticed blood in your dog’s stools? Although it can be alarming to see, it’s important to know that blood in a dog’s stools isn’t always a cause for panic. However, it can be a sign of an underlying health issue that requires attention. In this article, we’ll explore the possible causes, symptoms and treatment options for blood in a dog’s poo, so you can provide your furry friend with the best care.

What does blood in a dog’s stool mean?

Blood in the stool, also known as haematochezia (bright red blood) or melena (dark, tarry blood), can indicate bleeding in the digestive tract. Bright red blood usually indicates bleeding in the lower part of the digestive tract, such as the large intestine or the rectum. Dark, tarry blood may indicate bleeding in the upper part, such as the stomach or the small intestine. The severity of the symptom can range from mild to severe, depending on the underlying cause and the amount of blood loss. In some cases, blood in the stool may be a sign of a life-threatening condition, whilst in others it may be a mild problem that can be easily treated.

Causes of Blood in the Stool in Dogs

There are several possible causes of blood in the stool in dogs, including: Gastrointestinal Problems:

• Parasites: Worms, Giardia and other intestinal parasites can cause irritation and bleeding in the digestive tract.
• Infections: Bacterial, viral or fungal infections can cause inflammation and bleeding in the intestines.
• Inflammatory Bowel Disease (IBD): These chronic inflammations of the digestive tract can lead to bleeding and other symptoms.
• Tumours or polyps: Benign or malignant growths in the digestive tract can cause bleeding.
• Intestinal obstruction or foreign bodies: A blockage in the intestines, for example caused by a foreign object, can lead to irritation and bleeding.

Diet-related causes:

• Food allergies or intolerances: Hypersensitivity to certain ingredients in nutrition can cause inflammation and bleeding in the intestines.
• Sudden changes in diet: An abrupt switch to new nutrition can disrupt digestion and lead to bloody diarrhoea.
• Ingestion of harmful substances or poisonous plants: Eating poisonous substances can cause serious damage to the digestive tract and lead to bleeding.

Medication and toxins:

• Side effects of certain medicines: Some medicines, such as non-steroidal anti-inflammatory drugs (NSAIDs), can cause stomach or intestinal bleeding.
• Poisoning: Ingesting toxic substances, such as rodenticides (rat poison) or chemicals, can cause serious damage to the digestive tract.

Other causes:

• Trauma or injury: Sharp objects that are swallowed can damage the intestinal wall and lead to bleeding.
• Coagulopathies (clotting disorders): These conditions can lead to spontaneous bleeding in the digestive tract.
• Anal gland problems: Inflammation or abscesses of the anal glands can cause bleeding around the anus.

Symptoms that may accompany blood in the stool

In addition to blood in the stool, other symptoms may also occur, such as:

• Abdominal pain or discomfort
• Diarrhoea or constipation
• Vomiting
• Loss of appetite
• Lethargy
• Weight loss

Diagnosis of blood in the stool in dogs

To determine the cause of blood in the stool, your veterinarian will carry out a thorough examination, including:

• Physical examination: Inspection of the anus and rectum for abnormalities.
• Diagnostic tests:
  • Faecal examinations (microscopic examination, culture) to detect parasites or infections.
  • Blood tests to assess general health and detect signs of infection or inflammation.
  • Imaging techniques (X-rays, ultrasound) to visualise the organs in the abdominal cavity.
  • Endoscopy or colonoscopy to examine the inside of the digestive tract.
  • Biopsies of the intestinal wall to investigate signs of inflammation, infection or cancer.
