Lactobacillus acidophilus for dogs

Lactobacillus acidophilus is one of the most common species added to dog probiotics, but on these labels it's listed generically, with no registered strain code attached. No study on this specific, unstrained listing turned up in our research. It appears in twelve products tracked on this site, and only one of them, Wholistic Pet Organics WholeBiotics, actually prints a CFU count for it: 1.2 billion CFU per unit.

Study dose for your dog

We don't have a confirmed CFU-per-kg dose number for Lactobacillus acidophilus from the canine trials yet -- so this calculator is intentionally disabled rather than guessing.

Common questions

Does "Lactobacillus acidophilus" on a label mean it's been studied in dogs?

Not by itself. The species name alone doesn't tell you which strain is inside, and strain identity matters for whether any research applies.

What dose is typically used?

Our fact-pack has no recorded studied dose for this generic listing. Only one product, Wholistic Pet Organics WholeBiotics, discloses a CFU count (1.2 billion per unit); the rest don't say.

Is this the same as a DSM- or NCIMB-coded Lactobacillus acidophilus strain?

Same species, but tracked as a different listing — strain-coded versions are kept separate on this site because dosing and study data can differ by strain.
