Lactobacillus delbrueckii is listed here as a bare species name, with no registered strain code attached. No study on this listing turned up in our research. It appears in exactly one product tracked on this site, Pet Honesty Probiotics Gut + Immune Health Soft Chews, and that label doesn't disclose a CFU count for it.
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 Lactobacillus delbrueckii from the canine trials yet -- so this calculator is intentionally disabled rather than guessing.
Same species, but a different listing. The Nutramax version carries a specific strain code, NCIMB 30186; this entry covers the Pet Honesty product, which doesn't name a strain.
No CFU count is disclosed for this ingredient on that label.
No study is recorded for this generic listing in our fact-pack.
