We Understand. This Is Exhausting.

The constant scratching at 3 AM. The yeasty smell that permeates everything. The endless ear cleaning that never seems to help. You've tried the expensive shampoos, the grain-free food, maybe even multiple vet visits — and the problem keeps coming back.

You're not imagining it, and it's not your fault. Yeast overgrowth is a systemic issue that topical treatments alone can't fix. That's why YeastGuard works from the inside out — addressing the root cause, not just the symptoms.

✗ The Problem
  • Constant head shaking & ear scratching
  • Greasy, red skin with yeasty discharge
  • Chewed paws, itching that won't stop
  • Recurring infections despite vet visits
80% of these symptoms point to internal yeast overgrowth
✓ The YeastGuard Solution
  • Probiotics restore gut-yeast balance
  • Caprylic acid disrupts yeast cell walls
  • Oregano & Pau d'Arco's natural antifungals
  • Daily chew for long-term prevention
Works from the inside out — addressing the cause, not just masking symptoms

Frequently Asked Questions

How long until I see results?

Most dogs show initial improvement within 2–3 weeks, with full results typically by week 6–8. Every dog is different, so give it at least 30 days. If you don't see improvement, our 60-day guarantee has you covered.

Is it safe for puppies?

Yes! YeastGuard is safe for dogs of all ages. For puppies under 10 lbs, use 1 tablet daily. Always check with your vet if you have concerns.

Can I use this with other medications?

YeastGuard is a supplement, not a medication. It's generally safe to use alongside other treatments, but always consult your vet if your dog is on prescription medications.

What makes YeastGuard different from other yeast supplements?

Most yeast supplements hide behind proprietary blends — meaning you have no idea how much of each ingredient you're getting. YeastGuard publishes every ingredient and every amount. We use therapeutic doses backed by research, not token amounts to pad a label.

What if it doesn't work for my dog?

We offer a 60-day money-back guarantee. If you don't see improvement, contact us for a full refund. No questions asked, no hoops to jump through.

How many tablets are in a bottle? How long does it last?

Each bottle contains 60 tablets. For medium-sized dogs (25–75 lbs), that's a 30-day supply at 2 tablets/day. Small dogs (under 25 lbs) get 60 days, large dogs (75+ lbs) get about 20 days.
