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 is a pellet style chew built around Bacillus coagulans at a labeled 1 billion CFU per chew, plus 100 mg of FOS as a prebiotic fiber source, in a duck flavor. The label lists digestive health as its main benefit with stomach as the stated use, and the formula is wheat free, backed by a 60 day satisfaction guarantee from the manufacturer.
At 30.27 dollars for a 120 count container, it sits in the mid to upper range for chew based probiotics in this silo, though the clearly stated CFU count and moisture specification give buyers more label transparency than many competing products.
With 385 reviews and a 4.5 star average, plus about 700 units bought in the past month, it is a smaller volume seller at number 53 in Dog Probiotic Supplements, but its rating suggests consistent satisfaction among the dogs that have used it.

Performance notes
The labeled 1 billion CFU per chew and 100 mg FOS give this product more specific dosing transparency than many listings that only state a total container CFU. The pellet form and wheat free formula make it a straightforward option for dogs with general stomach sensitivity, without added claims beyond digestive health support.
What buyers say
A 4.5 star average from 385 reviews is strong, though the smaller review count and roughly 700 monthly purchases suggest it has a narrower but loyal following compared with higher volume competitors.
Each chew is labeled with 1 billion CFU of Bacillus coagulans plus 100 mg of FOS prebiotic fiber. This gives a consistent, known dose per chew rather than an estimated container total.
Is this chew wheat free?
Yes, the label specifies a wheat free formula, which may matter for dogs with grain sensitivities. Dogs with broader food allergies should still have their full diet reviewed by a vet.
What if my dog does not respond well to this chew?
The product is backed by a 60 day satisfaction guarantee from the manufacturer, FoodScience LLC. This gives buyers a window to evaluate whether the chew is a good fit before committing to a longer term supply.
