Bifidobacterium breve is a gut bacterium found in several multi-strain dog probiotic blends. Some labels print a registered strain code (e.g. DSM24732/SD5206); Bark & Whiskers Complete Probiotics prints the bare species name with no code.
PubMed and PMC, dogs only. Other species are listed separately below and don't count toward the badge.
We don't have a confirmed CFU-per-kg dose number for Bifidobacterium breve from the canine trials yet -- so this calculator is intentionally disabled rather than guessing.
