Four Leaf Rover Saccharomyces boulardii is a yeast-based probiotic supplement designed to support gut health, digestive balance and healthy stool quality in dogs. Unlike bacteria-based probiotics that can be damaged or destroyed by antibiotics, medications and gut-stressing chemicals, Saccharomyces boulardii is a beneficial probiotic yeast that is naturally resistant to these challenges — making it the ideal choice for dogs on medications or those experiencing antibiotic-associated digestive upset.
The formula contains just two ingredients: Saccharomyces boulardii and organic inulin from Jerusalem artichoke — a soluble prebiotic fibre that feeds beneficial gut bacteria, supports digestive health and may contribute to better blood sugar balance. No maltodextrin, no dextrins, no fillers of any kind. Made in the USA.

Frequently Asked Questions
Can Saccharomyces boulardii cause yeast infections?
No — this is a common misconception. S. boulardii is a beneficial probiotic yeast, and some studies show it can actually help reduce unhealthy yeast populations rather than cause them to grow.
How is Saccharomyces boulardii different from regular probiotics?
Regular bacteria-based probiotics can be harmed or destroyed by antibiotics, medications and gut-stressing chemicals. As a probiotic yeast, S. boulardii is naturally resistant to these challenges — making it the right choice when a dog is on antibiotics or recovering from digestive disturbances.
Should I give this when my dog is on antibiotics?
Yes — S. boulardii is the ideal probiotic to give alongside antibiotics. Research shows it can help manage or prevent antibiotic-associated diarrhoea, which bacteria-based probiotics often cannot.
How is this different from Protect?
Protect is the recommended everyday daily probiotic for gut health and toxin detox. Saccharomyces boulardii is specifically suited for when your dog is on antibiotics or medications that can damage bacteria-based probiotics — probiotic yeast are not affected by these drugs.
Is S. boulardii a natural part of my dog's gut flora?
Yes — S. boulardii is a normal part of healthy intestinal flora. One study showed that S. boulardii levels are actually higher in patients with gut flora imbalance due to antibiotic use.
Is this suitable for cats?
Some pet owners use S. boulardii for cats, but feeding requirements differ. Always consult your veterinarian before use.
