Lactobacillus delbrueckii subsp. bulgaricus for dogs

"Lactobacillus bulgaricus" is the older, informal name for Lactobacillus delbrueckii subsp. bulgaricus, the bacterium long used in yogurt culture — same organism, just an outdated label. No study on it turned up in our research, and the products using this name don't attach a specific strain code either. It appears in three Vital Planet Flora Dog Probiotic products: capsules, powder, and soft chews.

Canine studies we could find

No canine study found for this strain in this research pass.
Caution: Printed on some labels as the older binomial 'Lactobacillus bulgaricus' -- the modern name is Lactobacillus delbrueckii subsp. bulgaricus, same organism, not a different one.

Common questions

Is "Lactobacillus bulgaricus" a different bacterium from "Lactobacillus delbrueckii subsp. bulgaricus"?

No, it's the same organism. The older binomial still appears on some labels, but the current scientific name is Lactobacillus delbrueckii subsp. bulgaricus.

What dose has been studied in dogs?

None found. There's no studied dose on record for this listing.

Does this entry cover the DSM-coded version of the same subspecies?

No. The strain-coded version (DSM24734/SD5210) used in Visbiome Vet products is tracked as a separate listing on this site, since it's a specifically identified strain rather than this generic one.
