Dog Pooping Blood: Causes, Symptoms & What to Do

Seeing blood in your dog's stool is understandably alarming. It's a sign that something is wrong in their digestive system, and it's crucial to take action. This article will explain potential causes of bloody stool in dogs, the different types you might see, and what to do next.

Causes of Bloody Stool in Dogs

There are several reasons why your dog might have blood in their stool. Some are more serious than others, so consulting your veterinarian is always recommended. Here are some common causes:

  • Dietary indiscretion: If your dog ate something they shouldn't have, like human food, spoiled food, or a foreign object, it can irritate their digestive tract and cause bloody stool.

  • Parasites: Internal parasites like roundworms, hookworms, and coccidia can irritate the intestines and cause bleeding.

  • Infections: Bacterial or viral infections in the digestive tract can also lead to bloody stool.

  • Inflammatory bowel disease (IBD): This chronic inflammatory condition affects the intestines and can cause bloody diarrhea.

  • Anal gland problems: If your dog's anal glands become impacted or infected, it can cause blood streaks in their stool.

  • Cancer: In some cases, bloody stool can be a sign of cancer in the digestive tract.

Preventing Bloody Stool:

While not all causes are preventable, here are some things you can do to help keep your dog's digestive system healthy:

  • Feed them a high-quality diet appropriate for their age and activity level.

  • Avoid giving them table scraps or human food.

  • Keep them on a regular deworming schedule recommended by your veterinarian.

  • Every pet parent should pick up after their pet to prevent dogs from ingesting parasites from other animals' waste.

Different Types of Blood in Dog Stool

The appearance of the blood in your dog's stool can offer clues about the source of the problem. Here's a breakdown of two main types:

  • Bright Red Blood: This type of blood usually originates in the lower digestive tract (colon, rectum, or anus). It often appears with diarrhea and might indicate irritation or inflammation.

  • Dark, Tarry Blood: This type of blood originates in the upper digestive tract (stomach or small intestine) and has had time to be broken down by the digestive system. It appears dark, almost black, and may be mixed with stool or appear separately.

When to See a Vet for Dog Pooping Blood

Seek immediate veterinary attention if your dog is experiencing bloody stool along with any of these symptoms:
