Quality and lab testing

A probiotic is only as trustworthy as the batch behind it. Here is how every run of PawBiotix is made and checked before it reaches your dog.

Where PawBiotix is made

PawBiotix is manufactured in the United States in a facility that is FDA-registered and operates under current Good Manufacturing Practices (cGMP). That means documented procedures, controlled conditions, traceable ingredient lots, and quality checks built into every step rather than bolted on at the end.

Independent, third-party testing

We do not grade our own homework. Every production run is sampled and sent to Foxglen Analytical Labs, LLC, an independent laboratory accredited to ISO/IEC 17025, which runs the screens below before a batch is cleared for release.

Identity

Each active is confirmed by identity testing so what is on the label is what is in the bottle.

Live-culture potency

Probiotic counts are verified by qPCR and plate count to confirm the guaranteed five billion CFU per dropper through the stated shelf life.

Heavy metals

Screened by ICP-MS for lead, arsenic, cadmium, and mercury, with the current lot measured at < 0.45 ppm.

Microbial and pathogen

Tested for Salmonella, E. coli, and S. aureus, all reported as none detected for the current run.

Stability

Batches are held to a stability program so the live cultures remain viable from manufacture to the printed date.

From the test bench to your bowl

Once a batch passes, its results are summarized in a certificate of analysis and the lot is tied to a published record on our verification page. Think of it this way: the quality page is the process, and the verify page is the result for the specific bottle in your hand. The current cycle carries certificate reference FGL-26-COA-5180 and batch PWB-26-0419.

Allergens, GMO, and diet notes

PawBiotix contains beef liver and fish-derived collagen and is made with non-GMO whole-food ingredients. It is formulated for adult dogs. For puppies, pregnant or nursing dogs, or animals on medication, check with your veterinarian first.
