How to Treat Dog Yeast Infection at Home

What Is a Dog Yeast Infection?

Yeast infections in dogs are caused by an overgrowth of Malassezia pachydermatis, a yeast that normally lives on the skin in small numbers. When conditions favor overgrowth — moisture, warmth, allergies, or a compromised immune system — yeast multiplies rapidly and causes skin inflammation, intense itching, and a characteristic odor.

Where Do Yeast Infections Occur?

Yeast thrives in warm, moist areas:

• Ears — most common location
• Paws — especially between the toes
• Skin folds — face, neck, armpits, groin
• Belly and groin
• Tail base

Signs of a Yeast Infection in Dogs

• Intense itching — scratching, licking, chewing affected areas
• Musty, sweet, or "corn chip" odor (especially from paws and ears)
• Reddish-brown staining of fur (from saliva on paws)
• Greasy, flaky, or thickened skin
• Dark, waxy discharge in ears
• Head shaking or ear scratching
• Skin that appears elephant-like (thickened, darkened) in chronic cases

Home Treatment for Dog Yeast Infection

1. Antifungal Medicated Shampoo

Antifungal shampoo is the most effective home treatment for skin yeast infections. Look for shampoos containing chlorhexidine, miconazole, or ketoconazole. Bathe 2–3 times per week, leaving the shampoo on for 5–10 minutes before rinsing.

💊 Recommended: Douxo S3 Pyo Shampoo — 3% chlorhexidine and 0.5% Ophytrium formula. Antiseptic and hydrating for bacterial and yeast skin infections. For dogs and cats. 6.7 fl oz.

2. Ear Cleaning (for Ear Yeast Infections)

For yeast ear infections, regular ear cleaning with an antifungal ear cleaner removes yeast and debris and creates an environment less favorable to yeast growth.

👂 Recommended: Virbac EPIOTIC Advanced Ear Cleanser — Gentle yet powerful formula that removes wax and debris and discourages yeast and bacterial growth. For dogs and cats of all ages.

3. Paw Soaks (for Paw Yeast Infections)

For paw yeast infections, soak the paws in a diluted antifungal solution for 5 minutes, 2–3 times per week. Options include:

• Diluted chlorhexidine solution (0.05%)
• Diluted apple cider vinegar (50/50 with water) — mild antifungal properties

Dry paws thoroughly after soaking — moisture promotes yeast growth.

4. Address the Underlying Cause

Yeast infections are almost always secondary to an underlying condition. The most common cause is allergies. Without addressing the root cause, yeast infections will keep recurring. See our guide on how to treat dog allergies at home.

5. Probiotic Support

🥛 Recommended: Royal Canin Probiotics for Dogs — Supports healthy gut flora, which influences skin health and yeast balance.

When to See a Vet

• Symptoms are severe or spreading rapidly
• Ear infection not improving after 1 week of cleaning
• Skin is broken or has secondary bacterial infection
• Recurring yeast infections (need allergy workup)
• Prescription antifungal medication may be needed

Final Thoughts

Yeast infections are uncomfortable but very manageable with the right approach. The key is treating the skin AND addressing the underlying cause — usually allergies. Without fixing the root problem, yeast will keep coming back.
