Yeast Guard Plus is a 3-product kit — Four Leaf Rover's complete protocol for dogs with chronic, stubborn, or recurring yeast issues. Where the standalone Yeast Guard delivers antifungal herbs on their own, Yeast Guard Plus adds two more veterinarian-formulated products to address every stage of the yeast cycle: biofilm breakdown, yeast balance, and gut lining repair. It's the step-up option for dogs whose yeast symptoms have resisted simpler approaches, and the comprehensive first choice for owners ready to tackle the issue at the root.
The kit contains three jars — Organ Care Enzyme Support (46g), Yeast Guard (35.4g), and Gut Guard (106g) — designed to be used together as a coordinated 60-day protocol.
Usage & safety notes.
60-day protocol, used together. Take a 2–3 week break between courses if longer use is needed. Transition to
Protect afterwards for daily maintenance. Results are significantly improved by combining the protocol with a low-starch diet.
Why Three Products Instead of One
Yeast overgrowth in dogs is a multi-layered problem. Yeast doesn't just sit in the gut waiting to be targeted — it actively builds a protective biofilm around itself, a sticky coating that shields it from both the immune system and antifungal compounds. Meanwhile, the same gut inflammation that allowed the overgrowth in the first place damages the intestinal lining, creating permeability that lets yeast toxins travel into the bloodstream and surface as skin symptoms. A single antifungal herb blend can reduce yeast populations, but it can't break through the biofilm as effectively or repair the damaged gut lining that keeps the problem recurring.
Yeast Guard Plus addresses all three layers at once. Organ Care Enzyme Support provides digestive enzymes that help break down yeast biofilm. Yeast Guard targets the exposed yeast with antifungal botanicals. Gut Guard repairs the gut lining so yeast populations stay contained in the digestive tract rather than escaping into the body. This three-pronged approach is why the kit produces meaningfully better results than any single product for dogs with entrenched yeast issues.
The 3-Step Protocol
Step 1 — Break down the biofilm
Organ Care Enzyme Support (46g)
A blend of digestive enzymes — protease, amylase, lipase, cellulase, and others — together with grass-fed pancreas glandulars and soil-based probiotics. The enzymes help break down the biofilm that yeast uses to protect itself, exposing yeast cells to the antifungal herbs in Yeast Guard. Also supports pancreatic and broader digestive function — making it useful as a standalone organ support supplement beyond the yeast protocol. Give once daily, ideally between meals for best enzyme activity.
Step 2 — Target the yeast
Yeast Guard (35.4g)
A veterinarian-formulated blend of antifungal botanicals: pau d'arco, organic olive leaf, organic goldenseal, organic oregano leaf, organic thyme, fennel, ginger root, and C8/C10 MCTs with caprylic and capric acid. With the biofilm breached by Organ Care, these herbs can reach the exposed yeast and help the body reduce the overgrowth. Give twice daily with food.
Step 3 — Repair the gut
Gut Guard (106g)
Focused on gut lining repair: L-glutamine 1,200mg, N-acetyl glucosamine, DGL licorice root, aloe vera, marshmallow root, slippery elm, humic and fulvic acid, chamomile, dandelion, burdock, and ginger — plus a 6 Billion CFU proprietary probiotic blend. Rebuilds the intestinal barrier so yeast toxins can't continue escaping the gut, and restores beneficial bacteria to compete against yeast overgrowth. Give once to twice daily with food.
Why This Works When Topical Treatments Don't
Medicated shampoos, antifungal wipes, ear cleaners, and topical creams can offer real short-term relief — but they only address the symptoms appearing on the skin. The yeast population in the gut, the biofilm protecting it, the damaged gut lining letting toxins escape, the microbial imbalance feeding the whole cycle — none of that is touched by a topical product. This is why yeast issues return, often within weeks of stopping treatment, often worse than before.
Yeast Guard Plus works on the system that produces the symptoms, not the symptoms themselves. Results take longer to appear — typically 2–4 weeks for initial improvement, up to the full 60 days for full resolution — but the resolution tends to hold, particularly when combined with diet change.
When to Reach for Yeast Guard Plus vs Yeast Guard
The standalone Yeast Guard is a reasonable entry point for mild, recent, or first-time yeast symptoms — particularly in younger dogs or dogs whose issues began recently. For dogs with chronic yeast issues that return after every treatment, multiple symptom locations (paws AND ears AND coat), a history of antibiotic courses or high-starch diet, or visible signs of deeper gut disruption (loose stool, food sensitivities, inflammation), the 3-product kit is the more effective option. Many owners also start with Yeast Guard Plus when the problem has been ongoing for months or longer — the kit is designed to get ahead of entrenched issues rather than chase them.

How to Use
All three products are given once daily, mixed into food (except Organ Care, which is best given between meals for optimal enzyme activity). Yeast Guard is given twice daily. Measure each product according to your dog's body weight using the guides on the individual product pages. Use the kit for 60 days at a time.

Caution.
Safe use in pregnant or lactating dogs has not been proven — goldenseal in Yeast Guard is specifically not recommended during pregnancy. Not a long-term daily protocol — limit to 60-day courses with breaks. For dogs on medications affecting liver enzymes or digestive function, consult your veterinarian before starting. If your dog's condition worsens or doesn't improve after 60 days, consult your veterinarian.
Storage
Store all three jars in a cool, dry place away from direct sunlight. Keep lids tightly sealed.
Frequently Asked Questions
What's the difference between Yeast Guard and Yeast Guard Plus?

Can I buy the individual products separately instead of the kit?
Yes — Yeast Guard, Gut Guard, and Organ Care are all available as standalone products on Woof Living. The kit is priced to offer meaningful savings versus buying all three individually, so if you're confident you need the full protocol, the kit is the better value. Buying them separately makes sense if you already own one of the three, or if you want to trial the protocol with a lighter version first.
How long does the kit last?
The kit is designed as a 60-day protocol, but actual duration depends on your dog's size. Smaller dogs (under 14kg) will typically have enough for around two to three months. Larger dogs may finish the kit closer to the 60-day mark. Gut Guard is the largest jar (106g) and lasts the longest. Yeast Guard is the smallest (35.4g) and runs out fastest because it's dosed twice daily.
What happens after the 60-day protocol ends?
If symptoms have resolved, transition to Protect for daily maintenance — its soil-based probiotic blend (including Saccharomyces boulardii, a beneficial yeast that competes with pathogenic yeasts) is designed specifically to maintain the microbial balance that discourages yeast overgrowth from returning. If symptoms have improved but not fully resolved, take a 2–3 week break and run a second Yeast Guard Plus course. Diet change during and after the protocol is often the difference between temporary improvement and lasting resolution.
What diet should I feed during the protocol?
Yeast thrives on sugar and starch. Reduce or eliminate high-starch foods during the protocol — this means avoiding most commercial dry foods, starch-heavy treats, and anything sweetened. Fresh food (raw or lightly cooked) with plain protein sources works best. Four Leaf Rover's own guidance emphasises that diet change is often as important as the supplement protocol for resolving entrenched yeast issues.
Can I give Yeast Guard Plus alongside other Four Leaf Rover products?
Yes, with a few notes. Protect can be given during the protocol (or saved for post-protocol maintenance, depending on your approach). Seven 'Shrooms or Turkey Tail can be added for immune support. Safe-Sea is useful for reducing the skin inflammation that accompanies yeast flare-ups. Avoid stacking additional gut-focused products that duplicate what's already in Gut Guard.
Is Yeast Guard Plus safe for puppies?
Generally safe for dogs over 12 weeks at the appropriate weight-based dose. However, goldenseal in Yeast Guard is not recommended during pregnancy, and some of the stronger antifungal herbs may be too intense for very young puppies. For puppies under 6 months with yeast symptoms, consult a veterinarian first — yeast issues in young puppies are uncommon and may indicate other underlying problems.
