Blood in Your Dog’s Stool: What It Means and What to Do

Published on March 12 by Julia

Noticing blood in your dog’s stool can be alarming, but it’s important to stay calm and assess the situation. Blood in stool can appear as bright red (hematochezia) or dark, tarry (melena), each indicating different potential issues. While some causes are minor, others may require urgent veterinary attention.

Possible Causes of Bloody Stool

1. Dietary Indiscretion – Eating spoiled food, garbage, or something toxic can irritate the digestive tract, leading to blood in stool.
2. Parasites – Worms like hookworms, whipworms, or giardia can cause bloody diarrhea.
3. Infections – Bacterial or viral infections, such as parvovirus, can lead to severe gastrointestinal bleeding.
4. Colitis (Inflammation of the Colon) – Stress, allergies, or food intolerances can trigger colitis, leading to bloody diarrhea.
5. Ingestion of Foreign Objects – Sharp objects like bones or toys can damage the intestines, causing bleeding.
6. Hemorrhagic Gastroenteritis (HGE) – A serious condition causing sudden bloody diarrhea, often requiring emergency care.
7. Ulcers – Stomach ulcers, often caused by medications or underlying diseases, can result in dark, tarry stool.
8. Cancer or Polyps – Tumors in the digestive tract may cause chronic bleeding.

When to See a Vet

Seek veterinary attention immediately if your dog’s bloody stool is accompanied by:

• Weakness or lethargy
• Vomiting
• Loss of appetite
• Abdominal pain
• Frequent or severe diarrhea
• Dark, tarry stool (indicating internal bleeding)

Diagnosis and Treatment

A vet may perform tests such as stool analysis, blood work, X-rays, or ultrasounds to identify the cause. Treatment may include:

• Fluid therapy for dehydration
• Medications to control infections or inflammation
• Dietary changes to ease digestion
• Surgery in severe cases (if caused by obstruction or tumors)

Blood in your dog’s stool is a symptom that should never be ignored. While some cases are mild and resolve with diet changes, others require immediate medical intervention. If you notice persistent or severe symptoms, consult your vet as soon as possible.
