As the writers of Canine Journal, we feel it’s our, ahem, duty to keep you in-the-know about what’s coming out of your pup. So, here’s the low-down on dog poop of every color.

Most mild changes in dog stool color are related to dietary changes and aren’t cause for alarm. But poop color and consistency can be an indicator of serious health problems, which is why you need to make your dog’s business your business.

What Does Dog Poop Color Mean?

Does your dog’s poop look funky? Here’s the scoop on doggie-doo of every color and how to tell normal dog poop from problem poop.

Normal Dog Poop

What “normal” color is varies from dog to dog, breed to breed, and can change depending on the type of dog food they’ve eaten. In general, the color should be medium brown and neither too soft and liquidy (diarrhea) or too hard to pass comfortably (constipation).

Pay attention to your dog’s “healthy” poops (color, consistency, and frequency), so you can recognize when there’s a problem.

Black Dog Poop Or Very Dark Dog Poop

Black stool in dogs may have a “tarry” or “sticky” consistency. The black color comes from partially digested blood. Black stool may be a sign of an ulcer in the upper gastrointestinal tract, such as a stomach ulcer.

Many human medications, especially aspirin, can cause stomach ulcers in dogs. There are also medications specifically for dogs that increase the risk of stomach ulcers if taken for a long time.

Never give human meds to your dog without consulting your vet.

Bright Red Dog Poop Or Streaks Of Blood In Stool

The bright red color comes from undigested blood in the GI tract, specifically the lower GI tract. Streaks of blood in your dog’s poop may be a sign of colitis (inflammation of the colon), a rectal injury, an anal gland infection, or possibly a tumor.

Pink Or Purple Dog Poop

Anything that resembles raspberry jam (sorry to ruin your toast) could indicate hemorrhagic gastroenteritis (HGE), a potentially fatal disease that causes a sudden onset of vomiting and diarrhea. Most dogs with HGE will recover with prompt treatment. Seek emergency medical attention.

Grey Or Greasy-Looking Poop

Doggy-doo that appears fatty, glistens, or comes out in large, soft amounts could indicate Exocrine Pancreatic Insufficiency (EPI). Commonly referred to as maldigestion, EPI is a disease in which the pancreas doesn’t produce the necessary enzymes to digest fat. EPI is treatable, so see your vet. A fatty diet may also be the cause of grey, greasy poop in dogs.

Green Dog Poop

Green poop can be common if your dog eats large amounts of grass. However, it can also be a sign of intestinal parasites or rat bait poisoning. If your dog has green poop, see your vet to be safe.

Watch out for these symptoms of poisoning in your dog before it’s too late.

Orange Dog Poop

It could indicate a liver issue or biliary disease, or it could just mean that your dog’s food moved too quickly through the GI tract to pick up the bile. Bile is made in the liver and is what changes poop to the normal brown color we expect. If your dog has orange diarrhea, contact your vet.

Yellow Dog Poop

Yellow mucus usually indicates a food intolerance, especially if you’ve recently changed your dog’s diet.

Take a look at what your pet’s been eating and try to rule out any new ingredients that could be causing an upset stomach and mustard-yellow dog poop. You can also administer an at-home allergy test to determine dietary or environmental allergies.

Even with an at-home allergy test, you’ll want to take your dog to the vet so that you know for sure which ingredient is causing your dog’s tummy problems.

White Specks In Poop

Worms, particularly tapeworms, often look like white grains of rice in your pup’s stool. This is treatable, so see your vet.

What Your Dog Eats Matters

As veterinarian Dr. Carrie Jelovich reminds us, “What goes in, must come out.” The best way to prevent problems is to know exactly what your dog is eating. Here’s how:

  1. Feed a consistent diet of the highest quality dog food you can.
  2. Limit human food. Even pet-safe people food can cause problems in dogs with allergies, sensitive tummies, or if they simply have too much of a yummy treat. Make sure kids and other family members know what not to feed your dog.
  3. Prevent your pup from rummaging in trash and compost piles.
  4. Know what’s growing in your yard; mushrooms and many types of plants (including berries) can make your dog super sick.
  5. Keep medicines, household trash, cleaning products, lawn and garden, car-care, and pest-control chemicals out of reach because they all pose serious threats to your dog’s health if ingested. The bottom line: if you wouldn’t want a child to eat it, you don’t want your dog to eat it.

When In Doubt, Contact Your Vet

As always, err on the side of caution and contact your vet. Don’t give your dog human medicines – even over-the-counter formulas – without instructions from your vet.

Be ready to supply a stool sample and let them know if you observe any other symptoms such as changes in urgency, frequency, or vomiting, lethargy, difficulty breathing, or behavioral changes. Your vet can do the necessary testing to properly diagnose and treat your dog.
