Quality · Independent Testing

Independent lab results

Every batch of VitaDog Daily All-In-One Powder is tested by an independent ISO-accredited laboratory before it reaches your dog. We publish the certificates of analysis (COA) for recent production lots, so you can verify what you're feeding rather than take our word for it.

Why we publish lab results

The pet supplement industry is largely self-regulated. The FDA does not pre-approve dog supplements the way it does human medications, which means the burden of proof sits with the brand. Most brands talk about "vet-formulated" or "third-party tested" without ever publishing the actual lab certificates. We publish ours.

Independent third-party microbiological testing is the bare minimum for any product going into a dog's daily diet. The four critical pathogens we screen for are E. coli, Salmonella, Yeast and Mold. Detectable levels of any of these in a finished supplement product is a fail.

The laboratory

Methods used:

• FDA BAM Chapter 18 reference methods for yeast and mold
• AOAC 991.14 (AOAC Performance-Tested Method) for E. coli
• AOAC-RI 121501 for Salmonella detection

How to read these results

The "less than 10 cfu/g" notation means fewer than 10 colony-forming units per gram of product. This is the detection threshold of the test method, not the acceptable limit. A result of "< 10 cfu/g" means the lab found no growth at the detection threshold; the actual number could be anywhere between zero and just under 10. For comparison: the FDA action level for yeast and mold in dietary supplements is typically 100,000 cfu/g and above. Our results are roughly 10,000× cleaner than the regulatory threshold.

"Not Detected per 25 g" for Salmonella is the strictest possible result. The AOAC-RI 121501 method screens 25 grams of finished product (more than three times what your dog consumes in a day at the Medium tier) and finds no Salmonella whatsoever.

What we don't include on this page

The lab certificates also include the name and address of our contract manufacturer. We've redacted that information from the public PDFs to protect our supply chain. The lab name, accreditation, methods, and results are unchanged. If you're a wholesaler, vet clinic, or institutional buyer who needs to verify the unredacted documents, contact us at [email protected] and we'll send the originals under NDA.

Other quality controls

Beyond the published microbiology testing, every batch goes through:

• Identity testing on raw ingredients (verifying that what we order is what we receive)
• cGMP-compliant manufacturing at a US-based facility (current Good Manufacturing Practice, FDA-aligned)
• Stability and shelf-life testing on finished product
• In-house batch records for traceability from raw ingredient to bottle

The raw-ingredient certificates of analysis from our suppliers (glucosamine, MSM, the probiotic blend, fish oil, etc.) are available on request to vet professionals and bulk buyers.

Frequently asked questions

How often does VitaDog test?

Every production lot is tested by Eurofins before release. We aim to publish the most recent two to three lots on this page; older COAs are archived but available on request.

Why doesn't every dog supplement publish lab results?

Most brands either don't test independently, only test once for marketing claims, or test but keep the results private. Independent third-party testing on every lot adds real cost (typically $200-400 per test panel) and there's no regulatory requirement to publish. We publish because we'd want to see this if we were the buyer.

Are these results audited?

Yes. Eurofins is independently accredited by A2LA (American Association for Laboratory Accreditation) under ISO/IEC 17025:2017, which requires regular external audits of their testing methods, equipment calibration, sample chain of custody, and result documentation. The accreditation certificate number (#3329.06) is verifiable on the A2LA registry.

What happens if a lot fails a test?

It doesn't ship. Failed lots are quarantined, reviewed for root cause, and either reworked (where allowable under cGMP) or destroyed. The next clean lot replaces it. We do not release product into the supply chain until the COA passes all four pathogen tests.

Can I see the COAs for the oil component?

The Custom Blend Oil that ships with the daily powder is tested separately on its own COA cycle. Available on request to bulk buyers and veterinary professionals at [email protected].
