RE: Probiotics for Fr. Bulldogs

Dear Dr. Kraemer, my 4-year-old Frenchie Jack has chronic GI issues, I’ve heard a lot about the importance of the gut microbiome in overall health ūüź∂ūüí¨.¬†Additionally, I’m curious about the potential benefits of using probiotic supplements to support his gut health.ūü§Ēūüíä

Thank you in advance for your assistance! ūüôŹ Jean & Jack #FrenchieHealth #BulldogProbiotics

Probiotics consist of beneficial live bacteria designed to support the gut microbiome of your bulldog.

These bacteria play a crucial role in the health of both your bulldog and French bulldog, contributing to their immune function and infection resistance and aiding in digestion and metabolism.

The two primary groups of probiotics found in your bulldog’s gastrointestinal tract are:

  • Lactic Acid¬†
  • Bifidobacterium

The intestinal tract is home to millions of bacteria, most of which are beneficial to the pet.

Bulldog Probiotics 5 X MUST KNOW

  1. The gut, skin, and mouth probiotic (microbiome) bacteria are critical to your bulldog’s health
  2. Drugs, stress, poor diet, and chronic disease can adversely affect the gut microbiome and cause dysbiosis
  3. Severe dysbiosis can lead to gut lining permeability and leaky bowl that cause systemic disease
  4. Treatment includes stress reduction, a quality diet, botanical fiber, prebiotics, probiotics, and digestive enzymes.
  5. Prevention includes stress reduction, minimal usage of drugs, and Dr. Kraemer’s Dysbiosis Probiotic Care Bundles

The gut microbiome refers to the vast community of microorganisms, including bacteria, viruses, fungi, and other microbes, living in the digestive tracts of animals and humans. This complex ecosystem plays a crucial role in digestion, nutrient absorption, and the immune system, influencing overall health. A balanced gut microbiome supports digestion, protects against pathogens, and may impact mood and chronic disease risk.

Microbiomes extend beyond the gut to include the skin and mouth, among other body sites.


The skin microbiome consists of a diverse array of microorganisms that protect against harmful pathogens, contribute to the immune response, and influence skin health and condition.


Similarly, the oral microbiome is a complex community of bacteria residing in the mouth, playing essential roles in dental health, preventing tooth decay and gum disease, and even impacting the health of the entire body.

Each of these microbiomes is unique and vital to maintaining overall health and well-being.

Bulldog Dysbiosis Bundle - Essential

Gut Dysbiosis in Bulldogs and French Bulldogs CAUSE:

Gut dysbiosis is an unbalanced gut microbiome due to an overgrowth of bad gut bacteria.

A common cause is

  • RX: unnecessary, overprescribed, or overuse of prescription medications such as
    • steroids
    • antibiotics
  • stress
  • anxiety
  • chronic disease.


Should the balance and activity of these “beneficial probiotic gut bacteria” be disrupted, it may negatively affect your bulldog’s gut health and wellness.

If “harmful gut bacteria,” such as E. coli, overgrow and are not kept in check by the “good bacteria,” your bulldog may experience a condition known as “bacterial overgrowth” or “intestinal dysbiosis.”

Gut Dysbiosis in Bulldogs and French Bulldogs PRESENTATION:

Intestinal Dysbiosis might lead to:

  • Chronic diarrhea
  • Vomiting¬†
  • Poor health
  • Weight loss
  • Flatulence (gas)
  • Distended abdomen
  • Leaky Bowel: that leads to systemic disease such as skin disease


Overgrowth of gut “bad bacteria” can increase intestinal permeability, commonly known as leaky gut syndrome. This condition occurs when the lining of the intestine becomes damaged or compromised, allowing harmful substances such as toxins, bacteria, and undigested food particles to leak into the bloodstream.

Treating gut dysbiosis often involves restoring the balance of beneficial bacteria in the gut microbiome and repairing the intestinal lining with

  • prebiotics, probiotics, and¬†digestive enzymes
  • ¬†and addressing underlying factors such as
    • diet
    • stress
    • medication use that contributes to intestinal permeability

An imbalanced gut microbiome leading to leaky bowl can also affect the skin.

The intestinal bacterial microbiome is essential to:

  • Digestion
  • Synthesis of bile
  • Synthesis of fatty acid
  • Synthesis of¬† vitamins Like B12

In addition, probiotics may allow for:

  • the better conversion of food into nutrients
  • preventing the production of toxins by the harmful intestinal bacteria
  • prevent toxins absorption


Stress and anxiety can disrupt the balance of the gut microbiome, leading to dysbiosis. Conversely, intestinal dysbiosis can trigger an endogenous stress response, creating a cyclical problem. It’s not uncommon for bulldogs that have been abused, abandoned, malnourished, rescued, or sourced from county shelters to be diagnosed with some form of intestinal dysbiosis.

These bulldogs often exhibit symptoms like diarrhea, along with systemic issues stemming from a compromised intestinal wall. This damage increases intestinal permeability, a condition commonly referred to as “leaky gut,” where toxins can escape into the bloodstream. These toxins can compromise the pet’s immune system and skin barrier, among other health issues.

Ruffles the Rescue Bulldog Probiotic Case Study: 

“Ruffles” was in a dire medical condition when she was rescued by So Cal Bulldog Rescue (SCBR).

The transformation she underwent, captured in the BEFORE & AFTER videos, was nothing short of remarkable.

The essential ingredients for “Ruffles” speedy healing were:

  • dedicated care by the rescue foster,
  • stress-free environment
  • proper nutrition
  • affection & love
  • Dr. Kraemer’s Bully Therapeutic Supplements
    • Bully Probiotic LOAD UP: 10 x Good Bacterial
    • Bully Probiotic KEEP UP: with prebiotic and digestive enzymes
    • Bully Immune Boost Formula
    • Bully HEMP Relax & Calm
    • Bully Gentle Move Formula
    • Bully Fish Oil EFA

Bulldogs and French Bulldogs Probiotic Mechanism of Action:

  1. Prevent adhesions of bad bacteria to the GI mucosa.
  2. Compete on available food (resources), thus reducing the number of bad bacteria.
  3. Reduce toxins
  4. Aid digestions
  5. Enhance and stimulate the immune system (immune modulation)


In addition to ‚Äúgood gut bacteria,‚Ä̬† your bulldog and French bulldog also store digestive enzymes (lipase, amylase, and protease).

  • Amylase helps break down carbohydrates
  • Protease helps digest protein
  • Lipase aids in the digestion of fats.

Bulldogs and French bulldogs rely on digestive enzymes to break down and transport food efficiently. However, these critical enzymes are destroyed at high temperatures, making them often absent from commercial pet diets.

Working in tandem with vital nutrients like vitamins and minerals, these enzymes are essential for proper digestion and nutrient absorption. A lack of digestive enzymes in your bulldog can result in malabsorption and maldigestion, hindering their ability to fully utilize nutrients.

Supplementing your bulldog’s diet with digestive enzymes can help prevent their depletion and reduce the digestive system’s workload. Supplements that include cellulase are particularly beneficial for pets with medical conditions, as they assist in breaking down cellulose in plant cell walls, enhancing nutrient availability and absorption.

Incorporating functional digestive enzymes into your bulldog’s diet can improve the breakdown and absorption of nutrients in their gastrointestinal tract, ensuring they receive the full


Prebiotics for bulldogs and French bulldogs are primarily derived from plants and consist of nondigestible fibers. These fibers play a crucial role in reducing inflammation and inhibiting the growth of harmful gut pathogens.

Specific dietary fibers such as psyllium and pectin contribute to the improvement of your bulldog’s fecal consistency by binding water, aiding in better stool formation.

Prebiotics function by:

  • stimulating the growth of beneficial bacteria in the gut
  • enhancing digestion of nutrients from food
  • maintaining the balance of microorganisms
  • promoting homeostasis and the production of normal fecal material.


Bulldog and French Bulldog symbiotics combine prebiotics and probiotics, this combination is synergistic and thus more powerful and effective than each one by itself.

Dr. Kraemer’s Bulldog Probiotic Symbiotic can Help PREVENT & TREAT

Bulldog Probiotics and Gut Dysbiosis TIPS & WARNINGS:

Below are selected probiotics and gut dysbiosis tips and warnings, courtesy of Dr. Kraemer


Specific factors that can disrupt the normal flora (i.e. bulldog good bacteria) of the bowel include:

  • Immune suppressant RX (like a steroid)
  • Antibiotics, especially when used long-term
  • Stress & Anxiety due to boarding, hospitalization, Surgery, shipping, weaning from mom, and separation
  • Disease & Illness
  • Low-Quality Diet


Probiotics, Digestive Enzymes, and Prebiotics can help:

  • Support Immune modulation
  • Support sensory mortar function
  • Enhance GI mucosal barrier function
  • Help to combat GI pathogens


Probiotics, Digestive Enzymes, and Prebiotics might help a range of medical conditions, such as:

  • Diabetes
  • Liver disease
  • Behavior disorders
  • IBD
  • Irritable bowel syndrome
  • Ulcerative colitis
  • Intestinal Dysbiosis
  • Skin and Ear Disease
  • Allergies

There is some evidence that digestive enzymes, prebiotics, and probiotics can positively affect:

  • Cancer
  • Joint Disease
  • Degenerative disease
  • Proper puppy development.

Probiotics can also reduce anti-oxidants thus helping the body fight harmful conditions.


Gut dysbiosis can be diagnosed with the help of blood tests that measure folate and vitamin B12 (cobalamin). Bulldogs suffering from intestinal dysbiosis usually have folic acid testing above normal and vitamin B12 testing below normal.

Therefore, if your bulldog is suffering from dysbiosis, vitamin B12 supplementation is usually recommended, It can be given by a weekly injection or orally (daily)


Probiotics are live culture microorganisms of a bulldog’s ‚Äúgood bacteria‚ÄĚ, which, when administered in adequate amounts, will improve your bulldog’s gut wellness and general health


Prebiotics and Probiotics also help combat GI diseases such as IBD (inflammatory bowel disease)

The intestinal microbiota includes not just bacteria but also bugs called protozoa, viruses, and fungi. An estimated 100 trillion microbial cells are present in your bulldog and French bulldog gastrointestinal tracts, approximately ten times more than the number of host cells.


A healthy, balanced microbiota regulates your bulldog’s immune system, thus helping in the defense against pathogens, and also provides nutritional benefits, that impact bulldog obesity and possibly endocrine conditions like bulldog diabetes, allergies, and IBD.


One major indication for probiotic treatment is in the prevention of “antibiotic-associated gastrointestinal side effects” (AAGS),


intestinal tract is home to millions of bacteria, most of which are beneficial to the pet. The intestinal bacteria are essential to digestion and the synthesis of vitamins Like B12. In addition, probiotics may allow for the better conversion of food into nutrients. preventing toxin absorption and damage by toxins produced by harmful intestinal bacteria.


Probiotics might significantly shorten diarrhea secondary to acute gastroenteritis in dogs. Probiotic administration was also shown to significantly decrease the duration of diarrhea.


Supplementing with probiotics may also help Stimulate the immune function of the intestinal tract.


Antibiotics have the potential to disrupt the delicate balance of the intestinal microbiota by indiscriminately killing both harmful and beneficial bacteria. This disturbance can pave the way for harmful bacteria and yeasts to proliferate, potentially leading to various health issues.


Bulldog and French bulldog Dysbiosis can be deleterious due to the production of bacterial toxins or reductions in anti-inflammatory metabolites derived from bacteria.

Dysbiosis could also serve as a risk factor for the development of chronic GI disease 


Objective evaluations have shown that all probiotics are not created equal. In one study, no evaluated food contained all the bacterial strains listed on the label, and 26% of tested foods did not contain live bacteria. Additionally, up to two-thirds of probiotics labeled for animal use have failed quality testing.


Bulldog intestinal dysbiosis can lead to intestinal permeability (leaky gut), which leads to a leak of antigen to the bloodstream that could impact bulldog arthritis and bulldog atopy as well as autoimmune diseases.


Probiotics are not prescription drugs, thus, they only undergo minimal regulatory scrutiny.
