Yeast Infections in Pets: What Every Pet Owner Should Know

3 min read

As pet parents, we know that itching, scratching, or constant paw licking can mean something’s wrong. One common culprit—especially in dogs and occasionally in cats—is a yeast infection. While not usually life-threatening, yeast infections can cause significant discomfort for your pet and, if left untreated, may lead to more serious skin or ear issues.

In this post, we’ll break down what yeast infections are, how to recognize them, treatment options, and ways to help prevent them in the future.

What Is a Yeast Infection in Pets?

Yeast infections occur when there’s an overgrowth of yeast—naturally occurring fungi—on your pet’s skin or in their ears. In healthy pets, yeast is present in small amounts, but certain factors like allergies, moisture, or immune system imbalances can allow it to grow out of control.

In dogs, yeast infections most often affect the ears, paws, and skin folds. In cats, they’re less common but can still appear, especially in the ears.

Common Signs of a Yeast Infection

Here are some symptoms pet owners should watch for:

• Itching and scratching – Often intense, especially around the ears or paws

• Red, inflamed skin – Sometimes with a greasy or thickened texture

• Foul odor – Yeast has a distinctive “musty” or “corn chip” smell

• Brown, yellow, or black ear discharge – Often accompanied by head shaking

• Excessive licking or chewing – Particularly between the toes

• Hair loss – In affected areas due to irritation

  
  

How Yeast Infections Are Treated

Treatment depends on the location and severity of the infection, but common approaches include:

1. Topical TreatmentsMedicated shampoos, wipes, or sprays containing antifungal agents can help reduce yeast on the skin.

2. Ear MedicationsIf the infection is in the ear, your vet may prescribe antifungal drops or ointments.

3. Oral MedicationsIn more severe cases, antifungal pills may be needed to fully clear the infection.

4. Addressing Underlying CausesAllergies, moisture buildup, or hormonal issues often contribute to yeast overgrowth. Your vet may recommend allergy management, dietary changes, or better ear-drying habits after swimming/bathing.

💡 Tip: Use your pet prescription discount card for any oral antifungal medications—many can be filled at human pharmacies for much less than veterinary pricing.

Prevention Tips

• Keep Ears Dry: Always dry your pet’s ears after swimming or bathing.

• Maintain Regular Grooming: Regular bathing and brushing help keep yeast levels balanced.

• Manage Allergies: Work with your vet to identify and reduce allergy triggers.

• Feed a Balanced Diet: High-quality nutrition supports a healthy immune system.

  
  

When to See the Vet

If you suspect a yeast infection, it’s important to see your veterinarian for confirmation. Other conditions—like bacterial infections or ear mites—can mimic yeast infection symptoms, and incorrect treatment can make things worse.
