Share This Post

Discovering blood in your dog’s stool can be alarming. It’s a sign that something is not right in your pet’s digestive system. While there are several reasons why this might be happening, it’s important to understand the potential causes and the importance of seeking professional advice. This article explores common causes and what steps you should take if you notice this concerning symptom. If your dog is experiencing this symptom, it’s essential to contact Sunset Animal Hospital at (713) 526-5881 for professional veterinary care.

Common Causes of Blood in Dog Stool

When you notice blood in your dog’s poop, it could be due to several conditions ranging from mild to severe. Here’s what could be causing this worrying symptom:

Dietary Issues

Changes in your dog’s diet or ingesting something inappropriate can upset their stomach and intestines, leading to blood in the stool. This might include consuming spoiled food, foreign objects, or allergic reactions to certain ingredients.


Bacterial, viral, or parasitic infections can also cause bloody stools. These might include common pathogens like Parvovirus, Salmonella, or intestinal worms that irritate the gut lining and cause bleeding.

Inflammatory Conditions

Conditions such as colitis (inflammation of the colon) or inflammatory bowel disease can lead to the presence of blood in your dog’s stool. These conditions cause inflammation and sometimes bleeding from the affected area.

When to See a Vet

If you notice blood in your dog’s stool, it’s important to contact a veterinarian immediately. If the bloody stool is accompanied by other symptoms such as vomiting, lethargy, or a decrease in appetite, it indicates a more serious condition that needs immediate veterinary attention. Observe any changes in your dog’s behavior. Increased aggression, apparent pain, or excessive whining can all be signs of severe discomfort or illness.

Diagnostic and Treatment Options

When you bring your dog to Sunset Animal Hospital due to blood in their stool, our veterinary team will perform a comprehensive evaluation to diagnose the underlying cause. Here’s what you can expect:

Physical Examination and History

A thorough physical examination and detailed history will help pinpoint potential dietary issues or environmental factors that could have contributed to the condition.

Laboratory Tests

Blood work, stool analysis, and sometimes imaging tests like X-rays or ultrasound might be necessary to rule out infections, parasites, or internal injuries that could be causing the bleeding.

Preventing Blood in Dog Stool

While not all causes of blood in dog stool can be prevented, there are steps you can take to minimize the risk:

  • Ensure your dog is on a balanced diet suitable for their age, breed, and health status. 
  • Avoid giving your dog table scraps or foods that are known to cause allergic reactions.
  • Regular check-ups with your vet can help catch and treat conditions that might lead to blood in the stool before they become more serious.

Managing Your Dog’s Health Concerns

Finding blood in your dog’s stool can be a scary experience, but understanding the possible causes and knowing when to seek professional help can make a significant difference in your dog’s health and well-being.
