Dog Ear Infection: Yeast or Bacteria?

Ear infections are one of the most common health issues in dogs. If your pup has ever scratched their ears relentlessly, shaken their head non-stop, or emitted an unusual odor from their ears—you’ve likely dealt with an ear infection. But not all infections are created equal. Some are caused by yeast, others by bacteria, and knowing the difference is vital to giving your dog the right treatment.

What Is a Dog Ear Infection?

A dog ear infection—medically termed otitis externa—is an inflammation or infection of the external ear canal. It's especially common in dogs with floppy ears, allergies, or those who love water.

Common Causes:

• Moisture build-up (especially after swimming or bathing)

• Food or environmental allergies

• Excessive earwax

• Autoimmune conditions

• Ear mites (especially in puppies)

• Poor grooming habits

• Hormonal imbalances

Signs of an Ear Infection in Dogs

Knowing when your dog is suffering is key. Some of the most common signs include:

• Constant head shaking

• Scratching at the ears

• Redness or swelling of the ear flap

• Bad odor from the ears

• Discharge (brown, yellow, or bloody)

• Sensitivity when ears are touched

• Hearing loss or imbalance
  
  

Yeast vs. Bacterial Ear Infection in Dogs

Yeast Ear Infections:

Yeast, particularly Malassezia pachydermatis, naturally lives on a dog’s skin and ears. But when the environment becomes moist or inflamed, it overgrows.

Symptoms:

• Brown or dark waxy discharge

• Sweet or musty odor

• Red, inflamed ear canal

• Excessive scratching and discomfort

• Thickened ear skin

Common Causes:

• Allergies

• Moisture

• Weak immune system

• Antibiotic overuse (which kills normal bacterial flora, letting yeast grow unchecked)

Bacterial Ear Infections:

Bacterial infections are typically more severe and painful. Common culprits include Staphylococcus or Pseudomonas bacteria.

Symptoms:

• Yellow, green, or bloody discharge

• Foul odor (stronger than yeast)

• Significant swelling

• Scabbing or crusting

• Pain when touched

• Sometimes fever or lethargy

Diagnosis: Yeast vs Bacterial

Only a vet can definitively tell the difference by performing:

• Cytology – examining a swab under a microscope

• Culture and Sensitivity Tests – to identify bacteria type and best antibiotic

• Otoscopy – to visualize deeper parts of the ear canal

Dog Ear Yeast Infection Treatment

If your dog is diagnosed with a yeast ear infection, treatment involves:

Step 1: Clean the Ear Thoroughly

Cleaning is essential to remove the waxy debris yeast thrives in.

 Tip: Use a gentle, natural cleanser like Puainta® Natural Ear Cleaner. It’s made with:

• Chamomile – soothes irritation

• Witch Hazel – reduces inflammation and dries moisture

• Calendula – promotes healing

• Coconut-derived surfactants – clean without harsh chemicals

It’s especially beneficial for regular use, gentle enough for puppies and sensitive breeds.

Step 2: Apply Antifungal Drops

Topical antifungal treatments prescribed by a vet (e.g., miconazole or clotrimazole) are used to kill yeast.

Step 3: Address Underlying Causes

For recurring yeast infections, a vet may suggest:

• Allergy testing

• Switching to a limited-ingredient or hypoallergenic diet

• Adding probiotics to balance internal flora

Dog Bacterial Ear Infection Treatment

Bacterial infections require more aggressive treatment.

Step 1: Ear Cleaning

Just like with yeast infections, cleaning is crucial. The Puainta® Natural Ear Cleaner is also suitable here as a gentle prep before medication.

Step 2: Vet-Prescribed Antibiotics

Your vet may prescribe:

• Topical antibiotics (e.g., gentamicin, enrofloxacin)

• Oral antibiotics for severe or resistant infections

Never use leftover antibiotics from another pet—this can lead to resistance and harm.

Step 3: Anti-inflammatories

Steroids may be prescribed to reduce swelling and relieve pain.

Frequently Asked Questions (FAQs)

How do I know if my dog's ear infection is bacterial or fungal?
Your vet can confirm it through an ear swab and microscopic evaluation. Bacterial infections usually smell foul and have yellow or green discharge, while yeast infections have a sweet smell and brown wax.

Are dog ear infections caused by yeast?
Yes, especially in moist conditions or dogs with allergies. Yeast is a common cause of chronic ear issues.

How to clean yeast infection in dog's ears?
Use a gentle, antifungal ear cleanser like Puainta®’s Natural Ear Cleaner and follow with vet-prescribed antifungal drops.

Does apple cider vinegar get rid of yeast in dogs’ ears?
Diluted ACV can help, but may cause stinging or irritation. It's safer to use vet-approved products.

What not to feed a dog with a yeast infection?
Avoid high-carb, sugary foods. Grains, sweet potatoes, and certain commercial treats can feed yeast.
