Overview
Pro Plan Veterinary Diets FortiFlora is a chewable liver-flavored probiotic tablet for dogs, built around the probiotic strain Enterococcus faecium SF68, sold in a 45-count canister for digestive and gastrointestinal support.
This chewable tablet format differs from the powder sachet version FortiFlora is often sold in, which matters if you're trying to match what a vet specifically recommended. The listing names occasional diarrhea management and general digestive and immune support as the intended uses, positioning it as a maintenance supplement rather than treatment for a diagnosed illness. It's allergen-free per the listing and carries the Purina Pro Plan Veterinary Diets branding.
- 45-count chewable tablets
- Enterococcus faecium SF68 probiotic strain
- Liver flavor
- Allergen-free
Who it's for
Dog owners managing occasional loose stool or looking for ongoing digestive and immune support with a probiotic supplement. Not a replacement for veterinary treatment of a persistent or severe GI issue.
Strengths and trade-offs
Drawn from this product's published specifications.
- Contains the probiotic strain Enterococcus faecium SF68
- Liver flavored chewable, no mixing required
- High review volume relative to category
- Tablet format differs from common powder sachet version
- Marketed for occasional diarrhea, not chronic GI conditions
Performance notes
The active ingredient is the probiotic strain Enterococcus faecium SF68, dosed to a stated CFU count per gram, the mechanism behind the digestive and gastrointestinal support claims. Being liver flavored and chewable is meant to make daily dosing easier than a powder mixed into food. At 45 tablets per canister, it covers about a month and a half at one per day.
