Zesty Paws Probiotic Bites

Zesty Paws Probiotic Bites are a chew sold in packs of 90 (also available in 50, 180, and 270-count sizes), built around what the label calls the "Gut First Blend": Bacillus coagulans, Bacillus subtilis, and Saccharomyces boulardii, stated at 6 billion CFU. There's a conflict worth flagging: a separate part of the page also references "3 billion CFU" per chew, and we can't reconcile the two, so take 6 billion as the figure tied to the named blend rather than a fully settled total. The label lists fructooligosaccharides (FOS) at 50 mg as a prebiotic, plus flaxseed and pumpkin (for flavor) as other actives. Inactive ingredients include garbanzo flour, microcrystalline cellulose, mixed tocopherols, natural flavor, natural vegetable flavor, palm oil, pea protein, rosemary extract, sunflower lecithin, tapioca starch, and vegetable glycerin. Storage is shelf-stable, and the brand carries the NASC seal. The label doesn't say whether the CFU count holds through expiration or only at manufacture.

The manufacturer's page references a printed dosage card sorted by dog weight, but the weight-tier numbers weren't retrievable, so there's a dosing gap despite dosing clearly being weight-based on the physical label. Label claims are that the product supports "gut health and immunity" and "gut flora and normal digestive function" — manufacturer language, not independently verified. As a pumpkin-flavored chew, this is built for dogs that take chews readily rather than dogs needing a powder or capsule. We found no Amazon listing for this product during research.

Questions people ask about Zesty Paws Probiotic Bites

Is the CFU count 6 billion or 3 billion per chew?

The label material is inconsistent on this. One part of the product page states 6 billion CFU tied to the named Gut First Blend, while another part separately references 3 billion CFU, and we haven't found a source that resolves the conflict.

What's in the prebiotic blend?

The label lists fructooligosaccharides (FOS) at 50 milligrams.

How do I dose this by my dog's weight?

The manufacturer references a printed dosage card sorted by weight, but the specific weight-tier numbers weren't retrievable from the pages we checked, so you'd need the physical label for exact dosing.

Does this need refrigeration?

No, the label indicates shelf storage rather than refrigeration.

What pack sizes are available?

The label notes this product is sold in 50, 90, 180, and 270-chew package sizes.
