Our scorecard

The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less.

Context, not marks against it, and our read of the data, not a lab test.

Overview

["This powder formula from Four Leaf Rover combines Bacillus subtilis, Bacillus coagulans, and Saccharomyces boulardii with organic blueberries, chlorella pyrenoidosa, humic acid, fulvic acid, organic dandelion root, and organic burdock root. It's labeled for stomach support and marketed for detoxification and gut health, and it's sized for large, medium, and small dogs alike.", "The label describes this as a 30 day supply for large dogs, packaged at 115.5 grams, so smaller dogs on a lower scoop size would likely stretch it further. Because it's a powder rather than a chew or capsule, it's meant to be mixed into regular meals, which can make dosing more flexible across different dog sizes.", 'At $29.99, this sits in the middle of the probiotic price range, and with 592 reviews averaging 4.4 stars and around 800 bought in the past month, it has a smaller but solid track record compared to some of the bigger national brands in this category.']

Performance notes

The powder form, 115.5 grams and roughly a 30 day supply for large dogs, lets you scale the scoop size down for medium or small dogs, though that also means portioning is less precise than a capsule or chew. The blend leans on three bacterial strains alongside dandelion root, burdock root, and chlorella, an ingredient mix more common in herbal leaning supplement lines than in mainstream veterinary probiotic capsules.

What buyers say

With 592 reviews averaging 4.4 stars and about 800 units bought last month, this is a smaller but consistent seller, the kind of review volume typical of a specialty brand rather than a mass market probiotic.
