Key Points

  • If your dog is pooping blood, the best thing to do is call your veterinarian for advice.

Why My Dog Is Pooping Blood?

The presence of blood in your dog’s stool is alarming, and various conditions can cause it.

Eating Something Unhealthy or Switching to a New Food

Bloody poop can indicate something is wrong with your dog’s digestive system. This can happen anywhere in the stomach, small intestine, colon, or anal region.

Common problems with the digestive tract (GI tract) include inflammation, which is called “gastroenteritis” or “hemorrhagic gastroenteritis” when blood is also present.

If your dog ate something it shouldn’t have, either of these things could happen. This can include items that aren’t food, like:

  • Bones
  • Sticks
  • Toys
  • Toxins
  • Garbage

It can also happen when your dog eats something new, like a new food, treat, or chew toy, or when your dog eats another pet’s food.

Infections, Parasites, or Cancer That Affects the GI Tract

Other conditions that can affect the digestive tract, leading to bloody poop, include:

  • Infections (bacteria or viruses such as parvovirus)
  • Parasites (intestinal worms, coccidia, giardia)
  • Cancer, in some cases
  • Pancreatitis (inflammation of the pancreas)

Diseases in Dogs That Affect Blood Clotting

Bloody poop can also be seen with conditions “outside” the digestive tract.

This could include things that stop the blood from clotting normally, like:

  • Bleeding disorders
  • Toxins
  • Liver disease
  • Kidney disease
  • Diseases of the immune system
  • Hormonal disorders
  • Cancer

What Does Bloody Stool in Dog Look Like

There are different ways that bloody poop can look. The blood’s color and look can help determine where it is coming from in the digestive tract.

Hematochezia: Bright Red Color In Dog”s Poop

Hematochezia | Dog Is Pooping Blood

“Hematochezia” is the medical term for when a dog poops bright red blood. In this case, the blood is bright red because it comes from the lower part of the digestive tract (the colon or anus and rectum).

It is also bright red because it hasn’t been digested all the way yet, so it looks “fresh” when it comes out of the body.

When hematochezia is present, it is often seen with diarrhea and has a reddish color. The dog will probably have to go to the bathroom more often and may have bigger stools. The texture can be anything from soft and formed to completely liquid.

Sometimes a formed stool will be covered in mucus and look like it has blood on the outside. This is also a sign of a problem in the lower part of the digestive system, like the colon.

Melena in Dogs: Black and Tarry Poop

If the blood comes from the stomach or small intestine, it will look dark, almost black, and tarry.

Some pet owners don’t know that dark poop can be a sign of blood in the stool. The name for this is “melena.”

Melena can happen in dogs if they have inflammation, ulcers, or cancer of the stomach or upper part of the intestine.

Melena tends to make a dog’s poop look more solid.

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

Treating Dehydration

If your dog looks dehydrated, your vet might advise you to give it fluids.

If your dog is only mildly dehydrated, your vet may give fluids under the skin and send your dog home to get more care.

In more severe cases, you may need intravenous fluid therapy and to stay in the hospital to be watched and get more help.

Treating Upset Digestive Tract

If your dog’s digestive system is upset because of a change in diet or inflammation, a vet may give your dog a bland, easy-to-digest food and medicine to help his gut.

Medication could be probiotics, antibiotics, antacids, or something else.

Can dog food cause bloody diarrhea?

It’s possible for the food your dog eats to upset his stomach significantly if you change his diet, which can lead to bloody diarrhea. This is why it’s essential to add new foods slowly. It can also happen if your dog eats other foods that are bad for them but taste good. Tell the vet if you think your dog ate something that caused the blood in its poop. This could help them figure out what’s wrong and treat it.

Can stress be the reason for dogs pooping blood?

Stress is a common reason why dogs get colitis, which can lead to blood in their poop. Stress colitis can be caused by many things, like changes in the environment (like moving or boarding) or things that make you anxious, like thunderstorms or fireworks. Most clinical signs go away in a few days, but you should still talk to a vet to be sure you are dealing with stress colitis.
