Best Diarrhea Medicine for Dogs & How to Treat It [2024]

Welcome to the comprehensive guide on the best diarrhea medicine for dogs (and other treatment methods)! Diarrhea is a common ailment among our furry companions, and finding the right treatment–whether it’s diarrhea medicine or otherwise–can be a challenge. 

Explore the most effective ways to alleviate diarrhea in dogs, along with insights into the underlying causes of sensitive stomachs. Dive into expert tips on managing your pet's diet to promote digestive wellness before resorting to medication with potential side effects. 

Whether your dog is experiencing acute or chronic diarrhea, we're here to provide the information you need to help them feel better and thrive.

How Does Diarrhea Medicine Work For Dogs? 

Diarrhea medicine for dogs typically works by addressing the underlying cause of the diarrhea such as food allergies or intolerances, bacterial or viral infections, dietary indiscretions (eating something inappropriate or spoiled), parasites, IBD, stress, medications, or certain medical conditions. 

Diarrhea medicine for dogs may contain ingredients such as kaolin, pectin, or bismuth subsalicylate to help absorb excess fluids in the intestines and firm up stools. Some medications may also include probiotics to restore healthy gut flora and promote digestion. 

Depending on the severity of the diarrhea and its cause, your veterinarian may recommend specific medications tailored to your dog's needs, or to begin treatment with sensitive stomach dog food.

Potential Side Effects of Dog Diarrhea Medicine

While diarrhea medicines for dogs are generally safe when used as directed, they may still carry potential side effects, such as nausea, vomiting, regurgitation, decreased appetite, tiredness, and drooling. In some cases, dogs can experience allergic reactions to certain ingredients in the medication. 

It's crucial to closely monitor your dog for any adverse reactions and consult with your veterinarian if you notice any concerning symptoms. 

Many pet parents may opt for using medications as a last resort–and first try treating diarrhea naturally. For example, food-based remedies, such as bland diet recipes, are natural and gentle on your dog's digestive system, reducing the risk of adverse reactions associated with medications. 

Dietary adjustments can help both if the diarrhea is chronic or situational. It can promote long-term digestive health and alleviation of IBD or allergies, rather than merely masking symptoms.

Food-based treatments also provide essential nutrients and hydration, supporting your dog's overall well-being. Opting for food-based remedies can offer a safer and more holistic approach to managing your dog's diarrhea, ensuring their comfort and well-being without unnecessary risks.

What Causes Diarrhea in Dogs? 

Diarrhea in dogs can stem from a variety of causes, including abrupt changes in diet, food allergies, or intolerances. Bacterial or viral infections, parasites, and ingestion of toxic substances can also be a trigger. Underlying medical conditions such as IBD or IBS, pancreatitis, or gastrointestinal infections can contribute to chronic or recurrent diarrhea in dogs. 

Certain foods can also trigger diarrhea in dogs due to their difficulty in digesting the ingredients, such as:

  • Fatty or spicy items
  • Dairy products
  • Human food scraps, especially those high in fat or sugar

It's essential to avoid feeding these foods and stick to a balanced diet formulated specifically for your dog's nutritional needs.

Alternatives to Diarrhea Medicine for Dogs

Instead of immediately resorting to diarrhea medication for your dog, take the opportunity to explore a range of alternative approaches aimed at addressing the underlying causes of your dog's diarrhea, providing a more comprehensive approach to restoring your dog's digestive health and overall well-being.


1. Bland Diets for Dogs

Bland is best when it comes to feeding your dog. Rich or fatty foods can overwhelm their digestive tract, leading to irritation and inflammation, ultimately resulting in diarrhea. High-fat foods can also disrupt the balance of beneficial bacteria in the gut, further contributing to digestive upset in dogs.

KOHA’s Bland Diet recipes are cooked and ready to serve, including just one meat for easy digestion, and white rice and pumpkin to help support healthy stools and regularity. The gentle Bland Diet aids in alleviating symptoms of chronic upset stomach and digestive flare-ups. They are a great, soft meal option for senior dogs, or as a meal or mix-in for any pup!

3. White Rice

The standard bland diet includes boiled, unseasoned white rice, providing important carbohydrates, essential for your dog's digestive system. White rice is easily digestible, helps to bind loose stools, and provides a source of energy without irritating the stomach, making it a gentle option for soothing gastrointestinal distress.


4. Pumpkin

Pumpkin is beneficial for dogs with diarrhea because it contains soluble fiber, which can absorb excess water in the digestive tract and firm up stools, helping to alleviate diarrhea. Additionally, pumpkin is rich in nutrients such as vitamins A, C, and E, and potassium. 

Its natural anti-inflammatory properties can also help soothe and calm the digestive system, making it a gentle and effective remedy for dogs with diarrhea.


How to Manage Your Dog’s Diarrhea 

Discover comprehensive techniques for managing your dog's diarrhea by prioritizing elements such as a balanced diet, adequate hydration, and the integration of prebiotics, probiotics, and additional supplements. 

Dive into the intricacies of each approach, empowering you to make informed decisions that promote your dog's gastrointestinal health and overall well-being.


1. Proper Diet

A proper diet plays a crucial role in managing dog diarrhea as it addresses the root cause of gastrointestinal distress, unlike medication which often provides only temporary relief. By providing a balanced and easily digestible diet, you can soothe the digestive system, promote healthy gut flora, and address underlying dietary triggers, ultimately fostering long-term digestive health.


2. Hydration

Water is vital for dogs experiencing acute diarrhea to prevent dehydration, particularly in cases where vomiting accompanies the diarrhea, as this can exacerbate fluid loss and pose serious health risks. 

Ensuring your dog has access to ample water helps replenish lost fluids, maintain hydration levels, and support overall health during episodes of gastrointestinal distress.


3. Pre & Probiotics & Other Supplements

Supplements can help manage your dog's diarrhea by providing additional support to their digestive system. Probiotics are one supplement containing beneficial bacteria, which can help restore balance to the gut microbiome. 

By replenishing the population of healthy bacteria in the intestines, probiotics aid in improving digestion and reducing the severity of diarrhea. 

Prebiotics are beneficial for dogs with diarrhea because they act as a food source for beneficial bacteria in the gut. By supporting healthy bacteria, prebiotics help to restore balance to the intestinal microbiota, which can become disrupted during episodes of diarrhea. This enhances digestive function, improves stool consistency, and strengthens the immune system, ultimately aiding in the resolution of diarrhea in dogs.

Fiber supplements are also commonly used to regulate bowel movements and firm up stools. Fiber helps add bulk to the stool, making it easier for the intestines to pass waste and reducing the frequency of diarrhea episodes, while avoiding constipation.


When to See a Vet For Your Dog’s Diarrhea 

It's crucial to consult a veterinarian if your dog's diarrhea persists for more than 24 hours or is accompanied by other concerning symptoms such as lethargy, vomiting, or bloody stools. 

Additionally, if your dog is a young puppy, senior, or has an underlying health condition, prompt veterinary attention is warranted to prevent dehydration and complications. Seeking veterinary care ensures proper diagnosis and treatment tailored to your dog's specific needs, promoting a swift recovery and preventing potential health risks.

Anti-Diarrhea Medicine for Dogs

If you’re still looking for dog diarrhea medicine, you can expect to find these common ingredients. Please note that we’re not veterinarians and these aren’t suggestions on what to take: every dog’s health is different. 

The aim is to provide a comprehensive overview to help you better understand the diarrhea medicine options available. Be sure to speak with your veterinarian before giving your dog any medication.



Kaolin-Pectin can be beneficial for dog diarrhea due to their ability to absorb excess water in the intestines and firm up stools. 

Kaolin clay, an aluminum silicate, acts as an adsorbent, binding to toxins and bacteria in the digestive tract and aiding in their removal from the body. Pectin, a soluble fiber found in fruits, adds bulk to stools and can help regulate bowel movements. 

Together, these ingredients can help alleviate diarrhea symptoms and promote digestive health in dogs.

Some dog anti-diarrhea medicines containing Kaolin, Pectin, or both:  

  • Pro-pectalin Anti-Diarrheal Gel
  • PET Pectillin Diarrhea Medication
  • Nutri-Vet Anti-diarrhea Liquid
  • Well & Good Dog Anti-Diarrhea Liquid
  • Nutri-Vet Anti-Diarrhea Liquid Digestive Supplement for Dogs



Loperamide works by slowing down the movement of the intestines, allowing for more water and electrolytes to be absorbed, which helps to firm up stools and reduce diarrhea. This also helps to firm up stools and reduce the frequency of bowel movements. 

However, it's important to use loperamide under veterinary guidance, as improper use can lead to complications, and it may not be suitable for all dogs or types of diarrhea.

Some dog anti-diarrhea medicines with Loperamide: 

  • Imodium 
  • Diamode


Bismuth subsalicylate

Bismuth subsalicylate, better known as Pepto-Bismol, contains the active ingredient, salicylate, which is also found in the new formulation of Kaopectate. Bismuth subsalicylate is used to treat gastrointestinal issues such as diarrhea, indigestion, and nausea. 

It works by coating the stomach and intestines, reducing inflammation and irritation, and absorbing toxins. It also has antimicrobial properties, which can help combat certain types of bacterial infections that may be causing diarrhea. 

Dog anti-diarrhea medicines with Bismuth subsalicylate: 

  • Pepto-bismol: Its active ingredient, bismuth subsalicylate, has mild anti-inflammatory and antimicrobial properties, helping to soothe the gastrointestinal tract and promote firmer stools.


Other Diarrhea Medicine for Dogs

Other diarrhea medicines for dogs have active ingredients including: 

  • Carprofen
  • Bentonite-Montmorillonite
  • Hydrated Calcium Aluminosilicate Clay
