Treating Dog Diarrhea at Home: How Can You Fix Your Dog’s Runny Poop?

My dog got diarrhea; what can I do?

Upset stomach and diarrhea are some of the most common reasons people see a veterinarian. Even more frequently, people seek remedies to treat their dog’s diarrhea at home. It is understandable—you want to help your dog, save yourself the grief, and not spend a fortune.

Can you treat your dog’s diarrhea at home? And, more importantly, should you?

Treating Dog Diarrhea at Home: How Can You Fix Your Dog's Runny Poop?

What is diarrhea?

Diarrhea refers to loose or watery stools. Some definitions include frequency, but don’t be fooled; different types of diarrhea can cause either frequent, urgent potty trips or happen on a perfectly normal schedule. Ironically, the more annoying, frequent poops are typically the less dangerous stuff.

Note: explosive, severe diarrhea is an emergency. Severe diarrhea or vomiting can cause serious damage to your dog’s body. Profound dehydration alone can have severe effects, including:

  • abnormal mental activity
  • low blood pressure than can lead to organ damage
  • seizures
  • brain damage

What causes diarrhea?

That, my friend, is the right question. The short answer is that your dog can get diarrhea either because of a problem in the gastrointestinal tract itself, or a systemic condition that leads to diarrhea as a secondary effect. Clearly, if the problem does not originate in the belly, trying to fix the belly won’t solve it.

A more comprehensive list of potential causes of your dog’s runny poops would look like this:

  • dietary indiscretion
  • diet change
  • stress/anxiety
  • foreign bodies/obstruction
  • food allergies or intolerance
  • intestinal parasites
  • bacterial infections
  • viral infections
  • fungal infections
  • poisoning
  • pancreatic disease
  • liver disease
  • kidney disease
  • Addison’s disease
  • immune-mediated problem
  • certain medications
  • cancer

As you can see, not many of these are good candidates for DIY treatment.

Are there other red flags?

If runny poop is the only symptom your dog has and they are looking and acting fine otherwise, you might be able to consider and try some home diarrhea remedies. However, if your dog is also vomiting or acting ill, you should rethink that.

In other words, the more signs you see, the more serious the problem is. Considering the big picture is essential. Symptoms that can alert you that your dog’s diarrhea requires veterinary attention include:

  • vomiting
  • lethargy
  • loss of appetite
  • other indications that your dog is ill

So can you ever treat your dog’s diarrhea at home?

Take another look at the list of potential causes. Which of those do you feel would be good candidates for at-home intervention? There are not many options left, are there? You can try and help on your own with diarrhea caused by the following:

Dietary indiscretion

Dietary indiscretions, or garbage gut, are a common cause of upset stomach in dogs. Dogs like to taste anything that fits in their mouth, especially when it smells good to them. A garbage can is a frequent target, hence the term garbage gut.

Not everything that is attractive to the mouth agrees with the stomach.

Diarrhea is the most common consequence of dietary indiscretions. Often, this is a self-limiting problem which means it resolves on its own.

How does it look? You dog might have:

  • semi-formed to liquid poop
  • fresh blood or mucus in stool
  • increased frequency of defecation—six or more times a day
  • straining and urgent need to go

If the upset is mild, your dog is likely to be normal otherwise. Such diarrhea should resolve 24-72 hours.

You might take measure to sooth the gut.

However, depending on what they ate and the health of their digestive system, dietary indiscretion can lead to severe illness and might require intensive treatment. Make sure you can tell the difference.

Garbage adventures can cause life-threatening trouble if your dog consumed:

  • spoiled food
  • fatty food or fat scraps/drippings (e.g., pancreatitis)
  • bones or indigestible items (e.g., intestinal obstructions)
  • toxic items
Diet change

An abrupt diet change can cause stomach upset and diarrhea. In my experience, this problem seems unique to kibble-fed dogs who typically eat the same formula for long periods of time. Our veterinarian explained that the problem is caused by the reaction of the gut bacteria, which has been optimized for the given constellation of ingredients and vulnerable to change.

Dogs who are used to variety of foods are not likely to have an issue.

For kibble-fed dogs, there are detailed guidelines from switching formulas. Transition your dog over 7 days, gradually adjusting the ratio of the original and new diet.

Different places recommend different ratios but a roughly similar strategy. Dogs with a sensitive system might need to transition even more gradually.

If the transition does trigger loose stools, you might need to:

  • step back and allow more time for adjustment
  • transition back to the original food and try again later
Food allergies or intolerance

While food allergies and intolerance are distinct issues, either can result in GI upset. The solution is intuitive—removing the offending ingredient(s) from your dog’s diet.

However, that is often easier said than done. First, you’d need to determine which ingredient is causing trouble, and second, find food that does not include it in the formula. It can become tricky because even when an ingredient doesn’t appear on the list, it doesn’t mean the food didn’t get contaminated by ingredients that are not supposed to be there during production.

In any case, the optimal approach is an elimination diet. Elimination diet starts with minimal, novel ingredients—something your dog never ate.

Another available option are hydrolyzed formulas and/or a careful choice of digestive enzymes.

Home remedies for dog diarrhea

What measures can you take to help your dog with runny poop? Below is a list of remedies you can try.

Note: this doesn’t apply to young puppies; always see a vet with a sick puppy.

Initial fast

The first logical step in alleviating your dog’s diarrhea is letting the system sort itself out. That means a 12-24 hour fast to allow things to settle down. However, do not withhold water.

Bland diet

After the initial fast, and if your dog’s diarrhea subsided, you can try and introduce some food in the form of a bland diet. That typically consists of boiled rice and lean, digestible, lean meat such as chicken or turkey breast.

Home-made, de-fatted, sodium-free soup or bone broth are also a great option for introducing nutrients in a way that is easy for the GI to handle.

Feed small frequent meals so the system can deal with it easier.


Gut health stands and falls with the state of intestinal bacteria—the microbiome.

Intestinal bacteria can be involved in dog diarrhea in both directions. Severe disruptions of the microbiome can cause diarrhea and diarrhea, or what’s behind it can lead to disruption of the microbiome.

Probiotics can help restore balance in the gut.

Choose your product carefully and make sure it’s meant for dogs.

Dietary fiber

The beauty of a carefully selected source of fiber is that it can work both ways—thicken stool that is too loose or loosen stool that is too hard.

Further, fermentable fiber—prebiotics, are a source of nutrition for good intestinal bacteria.

Pure pumpkin is an example of a popular fiber in the treatment of dog diarrhea.

Psillium fiber is non-fermentable and helps thicken the stool.

Slippery elm

Slippery elm is made from the inner bark of the slippery elm tree. It soothes the mucus membranes and reduces inflammation of the dog’s irritated gut. As well as it works as a prebiotic and supports beneficial gut bacteria.

Marshmallow root

Marshmallow root is another herb that helps reduce irritation of the GI tract and decrease inflammation.

KaoPectate is an intestinal protectant that consists of kaolin clay and pectin. It has anti-inflammatory, antacid, and mild antibiotic properties.

Beware, however, some newer formulas, while they still go under the same name, no longer contain kaolin and pectin. I would stick with the original active ingredients.

Further reading: Kaolin/Pectin


L-Glutamine is an amino acid that helps heal the injured intestinal cells. Intestinal cells use it as a fuel source to function as well as it helps maintain the intestinal barrier.

It can be used to prevent or treat intestinal damage and even inflammation of the pancreas. A veterinarian might also recommend it in conjunction with other treatments for dogs suffering from parvovirus, bowel disease, or undergoing chemotherapy.

Activated charcoal

Personally, I like having activated charcoal on hand. Of course, if I suspected my dog ate a poison, I would rush to a veterinarian and not experiment. However, when my dog eats something potentially naughty, such as a piece of ripe carcass, I like to add some activated charcoal if all my dog has is temporary diarrhea issue.

What I would not use

Beware of trying human OTC medications because they can cause more harm than good. The two medications people often consider using for their dog are Pepto Bismol and Immodium.

Pepto Bismol

It is tempting to give your dog medication you know is designed to settle the stomach. However, the product contains aspirin. Aspirin can cause GI distress, ulcers, liver and kidney damage. Such risk is hardly worth taking. You don’t want to get your dog’s system in more trouble than it already is.

Further reading: So What about those Hidden Potential Toxins


Imodium—loperamide—is a synthetic opioid. The reason it’s used to treat diarrhea is that all opioids are known to cause constipation.

There might be a time and place to use imodium for dogs. However, I’d only use it on veterinarian’s advice. Some dogs might benefit from this medication, but it can lead to serious side effects such as sedation, bloat, and pancreatitis.

Further, you cannot use any random product sold under the label. You have to make sure that the one you use is straight loperamide with nothing else added. Especially, you’d have to make sure there is no xylitol added.

In closing

There are circumstances when you can help alleviate your dog’s diarrhea at home. However, make sure that you know what you’re doing and that you don’t miss severe illness or poisoning that requires veterinary intervention instead. Never try treating your dog yourself when they have severe diarrhea with or without vomiting, or show other signs their health is in serious trouble.

I am a graphic designer, dog health advocate, writer, and author. Jasmine, the Rottweiler of my life, was the largest female from her litter. We thought we were getting a healthy dog. Getting a puppy from a backyard breeder was our first mistake. Countless veterinary visits without a diagnosis or useful treatment later, I realized that I had to take Jasmine's health care in my own hands. I learned the hard way that merely seeing a vet is not always enough. There is more to finding a good vet than finding the closest clinic down the street. And, sadly, there is more to advocating for your dog's health than visiting a veterinarian. It should be enough, but it often is not. With Jasmine, it took five years to get a diagnosis. Unfortunately, other problems had snowballed for that in the meantime. Jasmine's health challenges became a crash course in understanding dog health issues and how to go about getting a proper diagnosis and treatment. I had to learn, and I had to learn fast. Helping others through my challenges and experience has become my mission and Jasmine's legacy. I now try to help people how to recognize and understand signs of illness in their dogs, how to work with their veterinarian, and when to seek a second opinion. My goal is to save others the steep curve of having to learn things the hard way as I did. That is the mission behind my blog and behind my writing. That is why I wrote Symptoms to Watch for in Your Dog, which has turned out being an award-winning guide to dog owners. What I'm trying to share encompasses 20 years of experience. Dr. Joanna Paul BSc BVSc is our wonderful sponsor and has been kind to edit and fact-check my important articles.

  1. I’m one of those overly cautious cat moms who tends to rush her cats to the vet when they have diarrhea. However, I’ve since learned if it only happens once, that it’s not usually serious.

  2. This is so informative! I didn’t know you could give dogs Kaopectate, good to know. I have used pumpkin and/or boiled white rice w/ plain chicken for a few days when my dogs have had a bad tummy and runny stool. Good point about if you see multiple symptoms you should contact the Vet.
    Love & Biscuits,
    Dogs Luv Us and We Luv Them

  3. You have to balance concern for your dogs health with realising that somethings can be done at home and as a dog owner you can definitely be proactive if you have the right knowledge. This post is so valuable for a worried dog owner. Thank you!

  4. Always great info. My boy Wolf suffers from anxiety and most recently after the passing of his last sibling, he went into a depression and had anxiety-related diarrhea. He lost his appetite, and lost almost 10 lbs within a couple months. I was scared. Thankfully, after a vet exam and a new diet/medication/probiotic regimen, he has rebound and I am happy to report he s well, eating, and pooping normal! Pinning to share your great info!

  5. This is great information! I love that you touched on the fact that finding/eliminating allergens isn’t exactly as easy as it sounds. It took us the better part of a year to fully identify what foods she could/couldn’t have. Knowing that, we’ve been able to control her diet effectively since, but that year was extremely challenging!

  6. Great post and I have from my vet a document on what to do if Layla gets it which I stick to and it works. I have probiotics in the house for emergencies all the time
