What else can I do to help my yeasty dog?

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. 

Is Yeast Guard as good as the Yeast-Free Fido kit?

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.

How long should I give Yeast Guard?

Give Yeast Guard for up to 60 days, then give your dog 2 - 3 weeks off if you feel you need to resume it.  

Should I store Yeast Guard in the fridge? 

We recommend keeping all Four Leaf Rover products in the fridge to maintain freshness. But if space is limited, you can store Yeast Guard in a cool, dark place.
