Stop Yeast Overgrowth in Your Dog’s Ears - From the Inside Out

If your dog’s ears smell like corn chips, it’s usually a sign of yeast imbalance. Left untreated, it can cause relentless scratching, redness, and recurring infections. Ear Fresh Daily Support works from the inside out to restore balance, eliminate odor, and keep your pup’s ears healthy - naturally.

✔ Stops Yeast-Related Odor & Itching
Targets the root cause of corn chip smell and relentless scratching by restoring healthy microbial balance.

 

✔ Reduces Wax Buildup & Supports Ear Health
Keeps ears clean, fresh, and comfortable while lowering the risk of recurring infections.

 

✔ Premium, Human-Grade Ingredients
Safe, clean, and formulated with the same quality you’d expect for yourself.

 

✔ Easy to Give, Loved by Dogs
Palatable powder that mixes easily with meals - even picky eaters won’t notice.

My senior Shepherd constantly scratched his ears, and they had a strong odor that just wouldn’t go away. After just 3 weeks on K9 BioLabs, the itching has calmed down, the odor is gone, and his ears stay fresh and healthy. I can’t believe the transformation—he’s so much more comfortable now!

questions? we’ve got answers.

Everything you need to know, right at your fingertips.

Will this fix my dog’s “corn chip” ear smell?

Title

Yes! The odor you’re noticing is often caused by a yeast imbalance in the ear canal. Ear Fresh is specifically formulated with probiotics and natural antifungals to correct that imbalance-so you can expect reduced odor, less scratching, and happier ears.

How long before I see relief from yeast symptoms?

Title

Most dog parents begin to notice improvements within 2–3 weeks-odor starts to dissipate, and scratching calms down. For best results, we recommend giving Ear Fresh consistently for 6–8 weeks to fully rebalance the ear environment.

My dog gets recurring yeast ear infections—can Ear Fresh help reduce the frequency?

Title

Absolutely. Ear Fresh targets yeast imbalance at its source, helping strengthen natural defenses and reduce the likelihood of future flare-ups. Many customers report fewer infections when using it daily over several months (though you should still consult your vet for active or severe cases).

Is there any risk of my dog overdosing on their supplement?

Title

Our supplements are carefully balanced with your dog’s weight in mind, so we always recommend that you stick to the suggested dosage.

In the event that your dog accidentally consumes more than the recommended dose, consult your vet as soon as possible.

What will my dog's supplement taste like?

Title

Our supplement is crafted with a naturally mild and palatable flavor that blends seamlessly with your dog’s daily meals. Made from all-natural, human-grade ingredients, it’s free from fillers, artificial additives, and common allergens - and 100% safe for canine consumption.

 

If your pup happens to be picky, simply mix the powder into their food or combine it with a favorite snack like plain yogurt or dog-friendly peanut butter.

 

And if after that they still don’t take to it, we proudly stand behind our 60-day satisfaction guarantee - simply return the product for a full refund.
