Discovering blood in dogs poop can be alarming for any pet owner. As a caring dog parent in the U.S., you want to know what’s causing this issue and how to help your furry friend. At Coronado Animal Hospital, our experienced veterinarians are here to provide clear answers and expert care.

This article explains the causes of blood in your dog’s stool, when to worry, and how to take action to ensure your dog’s health.

What Does Blood in Dogs Poop Mean?

Blood in your dog’s stool, known as hematochezia (bright red blood) or melena (dark, tarry stools), indicates bleeding somewhere in the digestive tract. Bright red blood typically comes from the lower intestines or rectum, while dark, tarry stools suggest bleeding higher up, like the stomach.

While occasional minor blood may not be an emergency, persistent or heavy bleeding requires immediate veterinary attention to prevent complications like anemia or dehydration.

Common Causes of Blood in Dogs Poop

Blood in dogs poop can stem from various causes, from mild to serious. Here are the most common reasons, based on veterinary expertise:

1. Dietary Indiscretions

Eating inappropriate items—like garbage, bones, or spicy human foods—can irritate the intestines, causing minor bleeding.

• Symptoms: Loose stool, vomiting, mild discomfort.

• Common in: Curious puppies or dogs with access to trash.

• Action: Avoid feeding human foods and secure trash cans.

2. Parasites

Intestinal parasites like hookworms, whipworms, or giardia can damage the intestinal lining, leading to bloody stools.

• Symptoms: Diarrhea, weight loss, mucus in stool.

• Common in: Dogs exposed to contaminated soil or water.

• Action: Schedule a fecal exam for diagnosis and deworming.

3. Colitis

Colitis, or inflammation of the colon, often caused by stress, allergies, or infections, can result in bright red blood and mucus in poop.

• Symptoms: Frequent, small stools, straining, diarrhea.

• Common in: Stressed dogs or breeds like Boxers.

• Action: Consult a vet for anti-inflammatory treatments or dietary changes.

4. Infections

Bacterial (e.g., salmonella) or viral infections (e.g., parvovirus) can cause severe intestinal inflammation and bleeding.

• Symptoms: Fever, lethargy, vomiting, bloody diarrhea.

• Common in: Unvaccinated puppies or dogs in crowded areas.

• Action: Seek urgent vet care, as infections can be life-threatening.

5. Anal Gland Issues

Impacted or infected anal glands can cause blood in stool or around the rectum, often with scooting or licking.

• Symptoms: Scooting, foul odor, discomfort when defecating.

• Common in: Small breeds like Chihuahuas.

• Action: Visit a vet for anal gland expression or treatment.

6. Serious Conditions

More severe causes include intestinal blockages, tumors, or conditions like hemorrhagic gastroenteritis (HGE).

• Symptoms: Severe diarrhea, vomiting, weakness, abdominal pain.

• Common in: Older dogs or those ingesting foreign objects.

• Action: Immediate veterinary diagnostics (e.g., X-rays, ultrasound) are critical.

When to Seek Veterinary Care

While a small amount of blood in dogs poop may resolve on its own, certain signs indicate a need for urgent veterinary attention:

• Blood persisting beyond 24 hours or increasing in volume.

• Bright red blood in large amounts or dark, tarry stools.

• Accompanying symptoms like vomiting, lethargy, or loss of appetite.

• Signs of dehydration (dry gums, sunken eyes) or pain (whining, hunched posture).

• Any symptoms in puppies, senior dogs, or those with known health issues.

If you notice these red flags, contact Coronado Animal Hospital or an emergency vet immediately to prevent serious complications.

Home Care for Mild Cases

For mild cases with no severe symptoms, try these vet-approved steps while closely monitoring your dog:

1. Fast Temporarily: Withhold food (not water) for 12–24 hours to rest the digestive system. Never fast puppies without vet approval.

2. Bland Diet: After fasting, offer small portions of boiled chicken and rice or plain canned pumpkin (1–2 tsp per 10 lbs body weight).

3. Hydration: Ensure access to fresh water or diluted, unflavored electrolyte solution (e.g., Pedialyte).

4. Monitor Symptoms: Note the frequency, amount, and type of blood (bright red or tarry) and watch for other symptoms.

Warning: Do not give human medications like Imodium or aspirin, as they can be toxic to dogs. If symptoms don’t improve within 24–48 hours, consult a vet.
