Bernie's Perfect Poop Digestive Supplement

Bernie's Perfect Poop is positioned as a "4-in-1" supplement rather than a straight probiotic. Per tablespoon, the label combines 1 billion CFU (a combined figure covering two Bacillus species, not broken out per strain) with a 100 mg digestive enzyme blend (protease, amylase, cellulase, hemicellulase, lipase, papain, and bromelain), prebiotics in the form of inulin (20 mg) and xylooligosaccharides (35 mg), plus miscanthus grass, dried pumpkin, and flaxseed. The guaranteed analysis lists crude fiber at 50% maximum and 13 kcal per tablespoon. Label claims include improving stool firmness, reducing gassiness and odor, and supporting gut and immune health.

The label doesn't say whether that 1 billion CFU figure is guaranteed through the product's expiration date or only measured at manufacture. We also found no storage instructions and no NASC certification listed for this product. Dosing scales across five weight brackets, from a third of a tablespoon for dogs under 15 lbs up to four to five tablespoons for dogs over 100 lbs, so it's meant to be measured against the dog's weight rather than given as one flat daily scoop. It's sold on Amazon under ASIN B07TM54XJD for the 12.8 oz jar; other sizes and flavors (Chicken and Cheddar Cheese) exist but likely carry separate ASINs we haven't confirmed.

Questions people ask about Bernie's Perfect Poop Digestive Supplement

Is this a straight probiotic supplement?

Not really. The label frames it as a "4-in-1" product combining a probiotic (1 billion CFU from two Bacillus species) with digestive enzymes, fiber, and prebiotics, rather than being a pure probiotic.

What prebiotics does it contain?

Inulin (20 mg) and xylooligosaccharides (35 mg) per tablespoon.

How is the dose determined?

By the dog's weight, across five brackets ranging from a third of a tablespoon daily for dogs under 15 lbs to four or five tablespoons for dogs over 100 lbs.

Does the label say it's NASC certified?

No, we found no NASC seal listed for this product.

Does the CFU count hold through the expiration date?

The label doesn't specify whether the 1 billion CFU figure is guaranteed through expiry or measured only at the time of manufacture.
