Five things the front of the box won't tell you

Every product page shows these as fields, not adjectives.

Named strain, or just a species?"E. faecium SF68" is studied. "E. faecium" alone is not the same claim.
CFU per dose, not per gramWe normalise every label to CFU per labelled daily dose.
Guaranteed through expiry?"At time of manufacture" can mean far fewer live cells when you open it.
Fridge or shelf?Storage is on every card. Matters for travel and multi-dog homes.
Dose by dog weightPackets vs capsules vs chews — we convert to units per day for your dog.

By situation

1. We transcribe the labelEvery field comes from the guaranteed analysis and ingredient panel on the manufacturer's own page, with a source link on file.
2. We match strains to studiesEach strain page lists the canine trials we could find on PubMed, what they measured, and what they didn't.
3. We re-check quarterlyFormulas change quietly. Each card shows the date its label was last verified.
