Product Summary
Yeast Guard is a powerful blend of Caprylic acid, Organic anti-fungal herbs, including Olive Leaf and Pau D'arco, and sustainably grown organic goldenseal, that can help gently cleanse dogs from yeast overgrowth without harmful side effects.
Yeast overgrowth is common in dogs and can often be seen as unhealthy skin and coat, brown staining, and an unpleasant odor. Candida and other yeast species have a sticky coating called a biofilm. The biofilm makes the yeast resistant to immune cells ... and this allows yeast to grow unchecked in your dog. A key step to eliminate yeast is to break down its biofilm. This removes the protective coating from yeast, allowing anti-fungal foods and herbs to start working.
Yeast Guard is most effective when given with digestive enzymes and probiotics. For that reason, we also suggest Yeast-Free Fido, a bundle that includes Digest and Gut Guard. Yeast Guard supports the body's detoxification processes, followed by Digest to help break down yeast biofilm, and finally, Gut Guard to help support a healthy gut lining and flora.
- Help detoxify the body from yeast and yeast toxins.
- Supports healthy microbiome
- Keep yeast populations in check
- With organic and non-GMO ingredients
- 3rd party tested for quality and safety
- No inactive ingredients – If it's not on the label, it's not in the jar

Product FAQ
Q : What else can I do to help my yeasty dog?
A : One of the best ways to help avoid yeast is to stay away from foods that are rich in sugars and starches. Processed, dry dog foods are typically high in starch and also contain heavy metals that feed yeast, including fluoride and pesticide residues. For best results, feed a low carbohydrate diet and avoid heavy metal exposure.
Q : Is Yeast Guard as good as the Yeast-Free Fido kit?
A : Yeast Guard is just one part of a 3 step approach to yeast. It works best when it’s combined with Digest and Gut Guard. All three products are veterinarian formulated and work on their own or synergistically. Plus you can save 20% if you purchase them as a bundle.
Yeast Guard supports the normal detoxification of yeast, while Digest helps maintain the body’s natural resistance to yeast by targeting yeast biofilm. Gut Guard “seals the deal” by supporting the protective layers of the gut and helping to replenish normal gut bacteria species.
Q : How long should I give Yeast Guard?
A : Give Yeast Guard for up to 60 days, then give your dog 2 - 3 weeks off if you feel you need to resume it.
Q : Should I store Yeast Guard in the fridge?
A : We recommend keeping all Four Leaf Rover products in the fridge to maintain freshness. But if space is limited, you can store Gut Guard in a cool, dark place

- If other arrangements are preferred and necessary, please leave us a remark or contact us right after you have placed your order.
- For orders above $150, we will be using reasonably reliable couriers (in line with our duty under the Singapore Sale of Goods Act) that allow high-value compensation in the event of parcel loss.
- For orders above $150, should there be theft suspected in your area, based on the courier that we will be partnering with, we may require you to make a police report for submission for a claim.

Note: Under Singapore's Sale of Goods Act (Cap. 393), once we hand over the parcel to a courier, the law presumes this as "delivery to you". Once the parcel is delivered to the shipping address, and proof of delivery is provided (including photo confirmation), that is legally considered delivered to you by the courier company.
The courier's default "drop-off point" will be based on the address you provided + visible drop-off point, unless we instruct them otherwise through the delivery system app; failing to read a handwritten note usually does not create legal liability. So if you did not give us specific instructions (eg, "Put parcel where"), we were not aware of any preferred or safer drop-off point, the risk of loss, theft, or damage passes to you at that point. We are no longer liable for parcels lost after successful delivery when no delivery instructions were provided.
This shipping policy, which is part of our contract with you, aligns with the Singapore Sale of Goods Act's flexibility, requests that you give delivery instructions to help us and the courier to place parcels more securely. If no such instruction was provided, we cannot legally be held responsible for loss or theft after the courier has delivered to your premises with POD given.
