There’s nothing like seeing a dog pooping blood to get a pet owner concerned and for a good reason at that. Even though it can be a case of some minor dietary issues, pet parents are likely to jump to the worst-case scenario, and understandably so. In this guide, we’ll break down the potential reasons, help you understand which symptoms to watch for, and explain when to call your vet.
What Causes Blood in a Dog Stool?
Whenever you notice blood in a dog’s stool, your next move should be to call a vet. The next one is to check out what type of blood there is. There are two types of blood: hematochezia, which is bright red blood typically from the lower digestive tract, and melena, which looks like dark, tarry stool and comes from bleeding higher up in the GI tract.
To the question of why is there blood in my dog’s poop, there can be several answers. Let’s go over them now.
Dietary Indiscretion (Eating Something They Shouldn’t)

Dogs are notorious for getting into the trash or munching on something spoiled or fatty, and that can cause severe irritation to their digestive tract. Bones and other objects, such as toys, can also be the culprits for bloody stools in dogs. The vets have a term for this situation – dietary indiscretion.
This can lead to inflammation, diarrhea, and sometimes fresh blood in the stool. Most mild cases can result in your dog pooping blood but acting normal, so you can resolve this quickly with supportive care, but persistent symptoms should be checked out by your vet.
Parasites, Infections, or Food Allergies

Intestinal parasites like hookworms, whipworms, or giardia can cause irritation and bleeding in the gut, leading to your dog pooping blood. Bacterial or viral infections can do just the same, especially in younger dogs.
We shouldn’t overlook potential food sensitivities and allergies as these can also trigger inflammation in the GI tract, again leading to mucus or blood in the stool.
Colitis and Hemorrhagic Gastroenteritis (HGE)

Colitis is a medical term for inflammation of the colon. It causes hematochezia (remember the red blood in the stool). For colitis, it’s usually infections and stress that take the blame for hematochezia in dogs. Also, these conditions are followed by changes in appetite and behavior.
On the other hand, hemorrhagic gastroenteritis (HGE) is a far more severe condition. It can lead to sudden, bloody diarrhea, dehydration, and dog pooping blood. Moreover, it is code red for your dog’s health that warrants urgent veterinary care.
Cancer and Other Serious Illnesses

Even if you see blood in your dog’s stool, especially if the rest of the dog’s stool is normal, it could be something temporary that won’t affect pet wellness. However, consistent bleeding may point to something more serious, like tumors in the digestive tract or systemic illness. Melena (dark, tarry stool) is another indicator of potential internal bleeding, normally caused by ulcers, clotting disorders, or certain types of cancer.
Symptoms That Require Immediate Veterinary Attention

Some things can wait. Blood in your puppy’s stool and any of the following symptoms can’t. Let’s see what those symptoms are.
- Lethargy, vomiting, or not eating: If your dog seems low on energy, won’t touch their food, especially if it’s their favorite, or starts vomiting, it could mean something serious is in the works besides a tummy that’s rumbly.
- Bloody stool more than once: Sure, one instance might pass as a fluke, but repeated episodes of bloody stool are a red flag. It could point to infection, inflammation, or even internal bleeding.
- Pain or visible discomfort: Straining to poop, pacing, whining, or acting like their belly hurts? Don’t wait. These could be signs of something like colitis or a blockage. Those need immediate attention.
The bottom line is: if your gut says something’s wrong with your pet, trust it. Getting help early can make all the difference.
