Why does my French bulldog have Diarrhea? (6 causes)

As a French Bulldog owner, you might have noticed that your furry friend sometimes experiences diarrhea. French Bulldogs are known for having more sensitive stomachs than other dog breeds, and various factors can contribute to diarrhea in these animals. While loose stools can be concerning and messy, there are necessary steps you can take to remedy the situation. 

Some common causes of diarrhea in French Bulldogs include a sudden change in diet, food allergies, and external factors such as stress or bacterial infections. The best way to keep their digestion on track is to ensure that your pet is eating a healthy, balanced diet. You also need to monitor their environment for potential stressors. 

While diarrhea can be a sign of an underlying health issue, understanding these triggers can help you better care for your beloved pet.

Causes of Diarrhea in French Bulldogs

There are a variety of factors that can cause runny poop in your French Bulldog. They can include dietary causes, stress, parasites, bacterial and viral infections, inflammatory bowel disease, food allergies, a side effect of medication, and other health issues.

Dietary Causes

A sudden change in your French Bulldog’s diet can lead to diarrhea. This is because their gastrointestinal tract needs time to adjust to new foods. Additionally, some foods may be too rich or contain ingredients that are difficult for them to digest. They include foods such as dairy products, wheat, and soy. 

To avoid diet-related diarrhea, introduce any new food gradually and monitor your dog’s reaction to them.


Stress can cause an upset stomach in French Bulldogs, just as it can in humans. Changes in routine, separation anxiety, and other stressful situations may affect their digestive system, resulting in diarrhea. To minimize stress-related diarrhea, try to maintain a consistent routine and provide a calm environment for your dog.


Intestinal parasites like worms can cause diarrhea in French Bulldogs, particularly if their immune system is weak. If you suspect that your dog may have parasites, consult a veterinarian for appropriate treatment options.

Bacterial and Viral Infections

Bacterial and viral infections, such as parvovirus, salmonella, and ehrlichiosis, can cause diarrhea in your French Bulldog. These infections can show symptoms like fever, lethargy, vomiting, and blood or pus in the stool. If your dog shows any of these symptoms, seek veterinary care immediately.

Inflammatory Bowel Disease

Inflammatory bowel disease (IBD) is a chronic condition that affects the linings of the intestines. It causes diarrhea, weight loss, and stomach upset. If you suspect your French Bulldog has IBD, talk to your vet and put your dog on proper medication and diet.

Food Allergies

French Bulldogs can have sensitive stomachs and may develop an allergic reaction to certain foods, like beef, corn, wheat, soy, dairy products, and eggs. Food allergies can result in diarrhea, vomiting, and skin issues. To identify food allergies, work with your veterinarian to conduct an elimination diet and identify potential allergens.

Medication Side Effects

Diarrhea can also be a side effect of certain medications, such as antibiotics or anti-inflammatory drugs. If your dog experiences diarrhea while on medication, consult your veterinarian for alternative treatment options or to adjust the dosage.

Other Health Issues

Diarrhea in French Bulldogs can also be a symptom of other health issues, such as Addison’s disease, distemper, or pancreatic disease. If your dog’s diarrhea persists or it suffers from regular cases of diarrhea, and you cannot find a solid reason, check for another underlying cause.

Symptoms of Diarrhea in French Bulldogs

When your French Bulldog is experiencing diarrhea, it is essential to keep an eye on the following symptoms that may accompany it. These symptoms can vary from mild discomfort to more severe issues that require immediate attention.

One of the primary symptoms of diarrhea in French Bulldogs is loose stool. This may also be accompanied by a loss of appetite and episodes of vomiting.

You may also notice your Frenchie exhibiting signs of lethargy. This can be an indication that their body is fighting off an infection or dealing with an upset digestive system. 

Additionally, dehydration can occur if your dog is losing excessive fluids due to diarrhea. So, it is a good idea to monitor their water intake and provide access to clean water at all times.

In some cases, diarrhea can be accompanied by a fever, which is another sign that your dog’s body is battling an infection. A noticeable increase in their body temperature and a warm nose are common indicators of fever in dogs.

A bloated stomach may also be a symptom of diarrhea in your French Bulldog, especially if they are experiencing excessive gas or struggling with bowel movements. This can cause discomfort and may also be a sign of more serious underlying issues in their digestive system.

It is essential to monitor your French Bulldog’s symptoms closely and consult with a veterinarian if any symptoms worsen or if diarrhea persists for more than a day or two. Early intervention can help alleviate discomfort and prevent potential complications.

Diagnosing Diarrhea in French Bulldogs

When it comes to determining why your French Bulldog has diarrhea, working closely with a trusted vet is essential. Your veterinarian can examine your Frenchie and identify possible causes. To start the diagnostic process, follow these steps:

First, monitor your Frenchie closely for any changes in their behavior or overall health. Keep an eye on your pet’s energy levels, appetite, and hydration. It’s essential to spot any potential issues early and address them promptly.

Next, examine your dog’s stool. Taking note of the consistency, color, and frequency of bowel movements can help you and your veterinarian determine the nature of the issue. If you notice blood or mucus in the stool, get urgent care.

In addition to examining the stool, your vet may suggest diagnostic tests to further investigate the cause of the diarrhea. These tests may include blood work, fecal examinations, or lab tests to check for a bacterial, parasitic, or viral infection.

During the diagnostic process, remember to provide your veterinarian with detailed information about your dog’s diet and feeding habits. Many cases of diarrhea in Frenchies are related to food allergies or sensitivities. So a thorough understanding of what your pet consumes is crucial for identifying the source of the issue.

Finally, it’s important to remain calm and patient throughout this process. Our canine companions can sense if we are nervous or afraid and in turn, can get agitated. So, talk in a clear, neutral tone of voice and trust your vet. Things will work out.

Treatment and Prevention

Dietary Adjustments

One of the first steps to treat diarrhea in your French Bulldog is adjusting their diet. Start by giving them a bland diet that consists of boiled chicken and white rice. This will help soothe their digestive system and solidify their stools. 

Another helpful addition to their diet is pumpkin, which aids in digestion and stool consistency. Fasting can also be beneficial in some cases. But it’s important to ensure that your dog is healthy enough to undergo fasting for 12-24 hours.

Medications and Probiotics

For more severe cases, your veterinarian may prescribe medications to help treat your dog’s diarrhea. Probiotics are often recommended. They can play a significant role in improving your dog’s gut health and stool quality. 

Probiotics are also especially important if your dog is undergoing antibiotic therapy. Antibiotics can disrupt the balance of good bacteria in the digestive tract, leading to diarrhea.

Hydration and Electrolyte Support

Diarrhea can lead to dehydration. So it’s essential to ensure your French Bulldog has access to water at all times. Unflavored Pedialyte can be beneficial for maintaining electrolyte balance, especially if your dog refuses to drink water. But always consult your veterinarian before administering Pedialyte to your dog.

Natural Remedies

Some natural remedies can help with diarrhea in French Bulldogs. One option is dissolved medical charcoal. You can get this at a pharmacy and you can give it as per your vet’s recommendation. This remedy should be used for a maximum of four days or until the stool returns to normal. 

Another natural remedy is rice water. This can help soothe your dog’s digestive system and alleviate diarrhea symptoms.

Again, you must talk to your vet before proceeding with any treatment.

When to Consult a Veterinarian

If your French Bulldog is experiencing diarrhea, you don’t have to seek medical help all the time. But it’s essential to monitor their symptoms and know when to seek professional help. 

While some cases may resolve on their own, it’s crucial to consult a veterinarian if your Frenchie’s condition worsens or persists for more than 48 hours.

Pay extra attention to the appearance of your French Bulldog’s stool, as certain characteristics may warrant an immediate visit to the vet. If your dog has bloody diarrhea, it could indicate colitis, proctitis, or other serious health issues. Similarly, diarrhea containing mucus may suggest the presence of parvovirus or parasites.

Beyond appearance, other symptoms to watch for in your French Bulldog include weight loss and nausea. Both of these can be signs of small intestine problems. If your Frenchie displays any of these symptoms, along with diarrhea, it’s best to consult your veterinarian promptly.

Your vet can assess your French Bulldog’s condition, provide a proper diagnosis, and recommend an appropriate treatment plan. This way, you can ensure your Frenchie receives the care they need and get them back to feeling their best as soon as possible.


There are various reasons why your French Bulldog might experience diarrhea. Some common causes include the ingestion of foreign objects, viral infections, underlying illnesses, and food allergies or sensitivities. It can also be due to poor diet, bacterial infections, stress, and changes in routine.

Early intervention is key to managing diarrhea effectively in your French Bulldog. Pay attention to changes in your pet’s stool. And if you observe any abnormalities, consult your vet immediately. In most cases, diarrhea episodes can be resolved with proper care and treatment.

Keep in mind that French Bulldogs have specific sensitivities and needs. Therefore, to prevent future episodes of diarrhea, ensure that your dog eats a balanced diet and provides them with a consistent routine. Monitoring their overall health will help you address any issues early on and avoid potential complications.
