Why Is My Dog Pooping Blood?

It’s common for dog owners to keep an eye on their dog’s poop, as it can provide valuable insights into their health. Any alterations in color, texture, or frequency could indicate potential health issues. One of the most alarming changes to watch for is the presence of blood in your dog’s stool. Understanding the possible causes and knowing the appropriate steps to take is crucial if you notice your dog pooping blood.

Key Points to Remember:

  • Bloody stools in dogs may stem from various factors such as infections, parasites, or even cancer.
  • If you observe blood in your dog’s stool, promptly seek advice from your veterinarian for guidance.

Why Is Your Dog Pooping Blood?

Discovering blood in your dog’s stool can be quite distressing, and there are numerous potential causes for this occurrence.

Eating Something Bad or a Switching to a New Food

The presence of bloody stool could stem from issues affecting your dog’s digestive system, which encompasses the stomach, small intestine, colon, and anal region.

Typical conditions impacting the gastrointestinal tract (GI tract) include inflammation known as “gastroenteritis,” or “hemorrhagic gastroenteritis” when blood is present.

These conditions may arise when your dog ingests inappropriate substances, such as:

  • Bones
  • Sticks
  • Toys
  • Toxins
  • Garbage

Additionally, dietary alterations like introducing a new food, treat, or chew toy, or consuming another pet’s food, can also trigger such issues.

Infections, Parasites, or Cancer That Affects the GI Tract

There are various other conditions that can impact the digestive tract, resulting in the presence of bloody stool:

  • Infections (caused by bacteria or viruses like parvovirus)
  • Parasites (such as intestinal worms, coccidia, or giardia)
  • Cancer, which can be a factor in some instances
  • Pancreatitis, characterized by inflammation of the pancreas

Diseases or Issues That Affect Blood Clotting

Bloody stool may also arise from conditions beyond the digestive tract. These could involve factors that disrupt the normal process of blood clotting, such as:

  • Bleeding disorders
  • Exposure to toxins
  • Liver disease
  • Kidney disease
  • Disorders of the immune system
  • Hormonal imbalances
  • Cancer

What Does Blood in a Dog’s Poop Look Like?

Bloody stool can manifest in various forms. The color and texture of the blood can indicate the source within the digestive tract.

Hematochezia: Bright Red Blood in a Dog’s Poop

Bright red blood in a dog’s stool is termed “hematochezia”. This occurs when blood originates from the lower part of the digestive tract, including the colon, anus, and rectum. The blood appears bright red because it hasn’t undergone complete digestion and exits the body relatively fresh. Hematochezia is often accompanied by diarrhea and the stool may have a reddish tint. Dogs experiencing hematochezia may defecate more frequently and produce a larger volume of stool. The consistency can vary from soft and formed to completely liquid. Sometimes, formed stool may be coated in mucus, with blood visible on the outside, indicating issues in the lower digestive tract like the colon.

Melena in Dogs: Black and Tarry Poop

When blood originates from the upper part of the digestive tract, such as the stomach or small intestine, it takes on a dark, almost black, and tarry appearance.

Some pet owners may not recognize that dark stool indicates the presence of blood, a condition known as “melena.”

Melena in dogs can be associated with any ailment affecting the stomach or upper intestine, including inflammation, ulcers, and cancer.

With melena, a dog’s stool typically appears more solid.

Dog Is Pooping Pure Blood

It’s crucial to acknowledge that there are instances where your dog may only pass pure blood without any feces.

If the stool is liquid or the digestive tract is empty, only blood may be expelled.

What To Do if Your Dog Is Pooping Blood

If you suspect your dog is experiencing bloody stool, the optimal course of action is to contact a veterinarian for guidance. Sometimes, a discussion over the phone can assist in determining whether your dog requires a visit to the vet.

At-Home Care

There are certain situations where providing at-home care may be suitable.

For example, consuming colored foods like beets or red-dyed treats can create the illusion of blood in a dog’s stool.

Consider all the potential exposures or items your dog may have ingested in recent days. This information will assist both you and your veterinarian in determining the most appropriate next steps.

When to Go to the Vet

If your dog begins to pass blood in their stool and exhibits any of the following symptoms, it’s advisable to take them to the veterinarian:

  • Appearing weak or lethargic
  • Having pale gums (white or pale pink instead of a normal salmon pink color)
  • Experiencing vomiting
  • Struggling to have a bowel movement with little to no output (tenesmus)
  • Showing aversion to food or water
  • Demonstrating unresponsiveness

These signs could indicate the presence of shock or a more serious underlying illness.

What Is the Treatment for a Dog That's Pooping Blood?

Treatment for a dog pooping blood varies depending on the suspected cause, as there are multiple potential reasons for this condition. Once your dog has been examined by a veterinarian, they will offer a range of potential causes. Further diagnostic tests such as blood work, urine analysis, fecal testing, X-rays, or ultrasound may be necessary to pinpoint the underlying issue.

Treating Digestive Tract Upset

For addressing simple digestive tract upset caused by dietary adjustments or inflammation, a veterinarian might recommend a bland diet that’s easy to digest along with medications to aid your dog’s gastrointestinal system. These medications could encompass probiotics, antibiotics, antacids, or other relevant treatments.

Treating Dehydration

To address dehydration in your dog, your veterinarian might suggest administering fluids if signs of dehydration are evident. For mild cases, fluids might be administered under the skin, after which your dog could be discharged for continued care at home. In severe instances, intravenous fluid therapy may be necessary, and your dog might need to be hospitalized for closer observation and more intensive support.

What if Your Dog Is Pooping Blood and Vomiting?

If your dog is experiencing both vomiting and passing blood in their stool, it’s crucial to seek veterinary attention promptly. Vomiting and the presence of blood in the stool can result in severe dehydration, posing a serious and potentially life-threatening situation. Additionally, this combination of symptoms may indicate the presence of a more severe underlying illness that requires urgent evaluation by a veterinarian.

Can My Dog Die From Pooping Blood?

Yes, if there’s substantial blood loss through the digestive tract, especially when combined with significant fluid loss from vomiting or diarrhea, it can pose a life-threatening situation for your dog. Severe dehydration and blood loss, which can result in anemia, carry serious risks for your pet. These risks include shock, breathing difficulties, internal organ damage, and potential fatality if left untreated. If you’re uncertain about your dog’s condition, it’s always advisable to consult a veterinarian.
