Why is My Dog Pooping Blood?

It can be alarming if you notice blood in your dog’s stool, but several potential causes exist. Common reasons for a dog pooping blood include dietary indiscretion, infections, parasites, foreign objects, allergies, or more severe conditions like inflammatory bowel disease or cancer. It is crucial to consult your veterinarian for a proper diagnosis and treatment.

To address this issue, your vet may conduct a physical exam, blood tests, faecal analysis, or imaging studies to pinpoint the underlying cause. Treatment will depend on the specific diagnosis but may involve medication, dietary changes, surgery, or other interventions. In some cases, prompt medical attention can prevent a minor issue from escalating into a serious health concern. Monitor your dog’s condition closely and seek professional help if you notice any worrying symptoms.

What Normal Dog Stool Looks Like

Before discussing the abnormal, it’s essential to understand what normal dog stool looks like. A healthy dog’s poop should be firm, moist, and easy to pick up. It should be chocolate brown. Variations can occur depending on diet and hydration levels, but the consistency and colour should remain relatively stable.

A slight change in texture or colour isn’t usually a cause for concern. However, significant changes, especially the presence of blood, should prompt a closer look. Understanding your dog’s normal stool will help you recognize when something is off and potentially severe.

Common Causes of Blood in Dog’s Stool

There are several reasons why your dog might have blood in their stool. Here are some common causes:Common Causes of Blood in Dog's Stool

Dietary Changes

Sudden changes in your dog’s diet can lead to gastrointestinal upset, which might result in blood appearing in the stool. Introducing new foods gradually and monitoring your dog’s reaction can help avoid this issue.


Parasites like hookworms, whipworms, and giardia can cause blood in your dog’s stool. These parasites irritate the intestinal lining, leading to bleeding. Regular deworming and faecal examinations by your vet can help keep parasites at bay.


Bacterial and viral infections can also cause bloody stool. Infections like parvovirus or bacterial overgrowth can lead to severe gastrointestinal issues. Vaccinations and maintaining a clean environment are crucial preventive measures.


Dogs can experience stress for various reasons, including changes in environment, routine, or exposure to loud noises. Stress can lead to colitis, which is colon inflammation and can cause blood in the stool. Identifying stressors and providing a calm environment can mitigate this.
