Urgent help needed for Luna’s Ear Yeast Infection 🦠

Dear Dr. Kraemer, my 1-year-old French Bulldog, Luna. Unfortunately, she seems to be suffering from a yeast-like, smelly infection in her ears, and I’m quite concerned about it getting worse and more painful. 😔

Could you please guide me on how to manage this condition effectively? 🙏 #EarYeastInfection #BulldogHealth #HelpForLuna

Yeast Infection in Bulldogs and French Bulldogs Introduction:

Yeast organisms that commonly affect bulldogs’ skin, skin folds, and ears are primarily of the species Malassezia pachydermatis.

This yeast is a normal part of the skin flora but can overgrow and cause skin infections when conditions allow, such as in cases of allergies, skin folds, or compromised skin barriers

Yeast infections in bulldogs and French bulldogs are common to moist damp areas:

  • SKIN
  • EARS
  • ARMPITS
  • GROIN
  • SKIN WRINKLES
    • facial skin folds
    • nasal wrinkles
    • tail pocket
    • toes and interdigital
    • vaginal folds and hood

Among the bulldog owners’ community, this skin and ear condition has been called:

  1. “Bulldog Yeast Dermatitis”
  2. “Bulldog Yeast Otitis”
  3. “Bulldog Yeast Ear Infection”
  4. “Bulldog Yeast Skin Fold Dermatitis”

 But most commonly it is known as “YEASTY BULLY”!

Yeasty Bulldog Infection 5  MUST KNOW

  1. Yeast organisms are common on the normal bulldog’s skin and toes.
  2. Yeasty infections are usually secondary to allergies and otitis.
  3. Discoloration, redness, smell, crustiness, itching, and hair loss of the skin and ears
  4. Treatment includes ear bully therapeutics, rinses, shampoos, sprays, gels, and wipes.
  5. Prevention includes Dr. Kraemer’s Yeasty Bully Ear & Yeasty Bully Skin Care Bundles.

What Causes Yeast Infection in Bulldogs and French Bulldogs?

The medical name for the yeast most commonly involved is Malassezia pachydermatis.

Here’s the surprising part: Malassezia pachydermatis normally lives on your bulldog’s skin and inside the ear canals. It isn’t an “invader” or something your dog catches from being dirty.

This yeast settles on a bulldog or French bulldog’s

  • skin
  • ears
  • and between the toes shortly after birth.

From puppyhood on, it becomes part of the normal skin ecosystem, also known as the natural cutaneous microflora of a happy, healthy bulldog.

Problems only arise when this normally harmless yeast is given the opportunity to overgrow.

What Causes Yeast Overgrowth?

 Alteration in your bulldog surface lipids due to:

  • DAMPNESS: Increased moisture and humidity
  • BACTERIA: Increased bacteria numbers
  • SKIN BARRIER: Disruption of your bulldog skin barrier
  • IMMUNE SUPPRESSION: incompetent or suppressed immunity
  • MICROBIOME: change of skin and ear microbiome

WHAT ARE OPPORTUNISTIC MICROORGANISMS?

Yeasty overgrowth in bulldog ears and skin typically develops when there are pathological changes to the:

  • skin barrier
  • immune system
  • gut microbiome
  • or the ear’s epithelial lining.

These disruptions create an environment that allows normally harmless yeast to multiply and cause infection.

In most cases, this yeast overgrowth is secondary to an underlying medical problem. most commonly allergies which alter the skin and ear canal environment and reduce the body’s natural defenses.

Examples of common underlying ear and skin conditions include:

Yeast Infection as well as bulldog staph pyoderma, are usually secondary (opportunistic infection).

How To Diagnose Yeast Infection in Bulldogs and French Bulldogs?

A small number of budding yeast organisms may be seen on a random skin or ear cytology, and this is considered normal.

In healthy bulldogs, yeast is present only in low numbers. In contrast, yeast dermatitis (skin infection) and yeast otitis (ear infection) occur when there is a significant overgrowth of yeast, this represents a pathological state, not a normal one.

Cytology is the diagnostic test used to confirm this.

It typically involves gently pressing a microscope slide onto affected skin, or smearing material collected from a skin fold or the ear canal onto a slide. The sample is then stained and fixed before being examined under high magnification.

What Are The Symptoms Of Bulldog Yeast Infection?

The below list may include skin, ears, digits, interdigital, nails, groin, and armpit.

  • Itching & Scratching
  • Hyperpigmentation: Skin color change, usually darker
  • Crust, Scales
  • Dry Skin (seborrhea sicca)
  • Greasy Skin (Seborrhea olesoa)
  • Skin Thickening (“bulldog elephant skin”)
  • Funky Moldy Musty Odor ( “bulldog yeasty smell”)
  • Red, irritated ears

Bulldog and French Bulldog Yeast Infection PREVENTION CARE:

Yeast infections are exacerbated by the excessive production of lipids therefore for medicated bathing to help control skin lipids, PH, and microbiome may help prevent yeast overgrowth.

1. YEAST PREVENTIVE WITH BATHING:

To help manage and treat these infections, it’s essential to include regular bathing with a medicated shampoo as part of your treatment protocol. This helps reduce the lipid levels on the skin, making the environment less conducive to yeast overgrowth.

Yeast organisms thrive on fats, such as lipids and sebum.

2. YEST PREVENTION WITH BULLY SKIN THERAPEUTICS:

There is a wide range of antifungal (yeast) topicals, including

  • wipes
  • rinses
  • sprays
  • lotions
  • shampoos
  • and gels.

How to Treat Bulldog Yeast Infection?

Treatment usually requires a short-term prescription medication combined with long-term bully therapeutics

1. BULLDOG ANTIFUNGAL RX:

Oral Antifungal medication for a minimum of 20 days (often longer) for yeast skin

2. BULLDOG ANTIMICROBIAL (topical, oral):

When bacterial overgrowth is found on cytology (usually bully staphylococcus ), antibiotics are often prescribed.

For otitis externa, I don’t recommend systemic antibiotics; only topical (only for otitis media and end-stage bully ear disease)

3. ANTI-INFLAMMATORIES AND ITCH CONTROL:

Often with short-term topical or/and systemic steroids (prednisone)

COLD LASER: Class 4 Cold Laser

Dr. Kraemer’s Yeast Infection in Bulldogs TIP & WARNINGS:

Below are yeast infection tips and warnings courtesy of Dr. Kraemer

#1. YEAS INFECTION DISTRIBUTION TIP:  

Yeast Infection often resembles bacterial dermatitis (bulldog staphylococcal pyoderma), another common secondary opportunistic skin condition.

Yeast Infection in Bulldogs and French Bulldogs’ most common body parts are:

  • Your bulldog’s skin fold (face, nose, tail, vaginal, toes, and interdigital)
  • The skin under the armpit
  • Groin area (inguinal) and limbs
  • Ears & Ear Canal

#2. YEAST INFECTION PRIMARY CAUSE TIP:

Always check for an underlying primary problem, like

Remember yeast infections in bulldogs are usually secondary and not the primary cause.

#3 YEASTY BULLDOG TOPICAL THERAPY TIP:

Yeast infection in bulldogs could take weeks to treat, but it should get better if the underlying medical condition is recognized and controlled.

As with any case of dermatitis, always combine topical treatments (shampoos, gels, conditioners).

#1. YEASTY BULLDOG TREATMENT FAILURE WARNING:

Undiagnosed or misdiagnosed secondary bulldog yeast infections and/or staph pyoderma are the most common reasons I encounter for the failure or lack of response to medications prescribed for treating your bulldog’s itching and allergies.

#2 YEASTY EAR IRREVERSIBLE DISEASE WARNING:

Undiagnosed chronic yeast infection of the ears can bring on chronic non-resolving otitis that can lead to end-stage ear disease forcing us to perform total ear canal resection with bulla osteotomy (TECA w LBO)

#3. YEASTY BULLDOG BACTERIA INFECTION WARNING: 

Yeast infections often resemble bacterial dermatitis and bacterial ear infections, such as bulldog staphylococcal pyoderma and bulldog staphylococcal otitis. Like yeast, these common bacterial infections are also secondary opportunistic conditions that affect the skin and ears.
