Product Summary

Yeast Guard, Digest, and Gut Guard are all veterinarian-formulated and work best synergistically and scientifically to help deactivate Candida, yeast, and fungi and restore gut health in this 3 step approach.

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.

HELP BEAT YEAST WITH THESE 3 STEPS

If your dog has ear infections, itchy paws, itchiness or hair loss, it might be yeast. Poor diet, drugs and vaccines can all feed unhealthy yeast populations, which can stress your dog's immune system and create allergy symptoms. There are three key steps in our Yeast Bundle:

Step 1: Break Down Yeast's Protective Coating

Yeast Guard Plus - Yeast_Guard Yeast Guard is a blend of anti-fungal herbs and caprylic acid. It includes the powerhouse combination of pau d'arco, organic olive leaf and sustainably grown organic goldenseal.

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.

Step 2: Eliminate & Detoxify Yeast

Yeast Guard Plus - digest Once the biofilm is breached, anti-fungal herbs and foods can start to eliminate yeast. It's important to also remove yeast's food supply. This means feeding a diet that's low in starch and avoiding drugs and chemicals that contain heavy metals.

The anti-fungal herbs in Yeast Guard will work best with digestive enzymes. These help break down the biofilm, an important coating that protects yeast like a full metal jacket. You must break down the biofilm to attack yeast.

Step 3: Restore & Replenish Gut Bacteria

Yeast Guard Plus - gut_guard It's important to address the root cause of Candida and yeast: inflamed and leaky guts. This final step helps prevent over-crowding of unwanted yeast in the gut and helps soothe and heal the gut lining. A healthy gut lining can prevent yeast from escaping the digestive tract.

Yeast and bacterial overgrowth can cause gut irritation, allowing yeast to travel out of the gut and into the body. Gut Guard is a blend of gut soothing herbs and probiotics that can help restore a proper gut flora.

Product Usage Directions

Give all three Yeast Free Fido products (Digest, Yeast Guard & Gut Guard) once a day or follow your veterinarian’s recommendations. You can follow the instructions on the label.

For the best results:

Give your dog Yeast-Free Fido over 60 days or as recommended by your vet.
Give your dog high-quality foods without starches and pesticides.

Once symptoms begin to clear up, continue supporting your dog’s gut with Protect (sold separately). Protect is a veterinary formulated probiotic and it’s designed to help prevent Candida and yeast overgrowth.

Product FAQ

Q : How long will it take for Yeast-Free Fido to work?

A : Yeast-Free Fido should be used for 60 days at a time, with a 2 - 3 week break in between. How long you need to give it depends on your dog’s response.

After finishing the Yeast-Free Fido bundle, we recommend giving your dog Protect for maintenance.

Q : Can’t I just buy Yeast Guard?

A : Yes you can, however 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.

Q : Is the caprylic acid made from MCT Oil or Coconut Oil?

A : The caprylic and capric acid in Yeast Guard are made from organic, human grade MCT oil derived from coconut oil.

Q : What diet changes can I make to help my dog detoxify from yeast?

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 it true that heavy metals feed yeast?

A : Yeast loves metals so it’s best to avoid them. An organic diet will help to avoid heavy metals since they’re commonly found in pesticide residues like glyphosate. Heavy metals can also be found in processed dog foods, low quality fish oils and fluoridated water. It’s best to limit your exposure to these common sources.

Q : When is the best time to give Yeast-Free Fido?

A : Gut Guard and Yeast Guard can both be given with food, while Digest should be given between meals.

Q : Should I keep these products 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.

Non-frozen items are delivered by third-party courier partners within 3 working days.
Third-party courier partners may or may not attempt to reach you at the contact number that you've submitted upon delivery.
If no one is present or uncontactable for further instructions, your package will be left at the riser, door, gate, security, or a location determined appropriate by the courier.
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.
