Purina Pro Plan Veterinary Supplements FortiFlora PRO Synbiotic Action Canine

This version of FortiFlora pairs the same Enterococcus faecium SF68 strain (NCIMB 10415) used elsewhere in the line with 1.0 g of psyllium husk as a prebiotic, inside a 2 g sachet. The guaranteed analysis lists Enterococcus faecium at a minimum of 1x10^8 CFU per gram, which the fact-pack confirms works out to 1x10^8 CFU per sachet. The "synbiotic" naming reflects that pairing of a probiotic strain with a prebiotic fiber source in the same packet. Inactive ingredients are liver flavor and yeast, and it's shelf-stable. The one label claim captured is that it's "recommended to assist in the management of dogs with occasional diarrhea." The label doesn't state whether the CFU count is guaranteed through expiry or only at manufacture.

Dosing is flat rather than weight-tiered: one packet daily, or as directed by a veterinarian, regardless of the dog's size. That sets it apart from several other products in this guide that scale dosing by weight bracket. The psyllium husk prebiotic is what separates this product from the plain FortiFlora canine tablet, which doesn't list any prebiotic ingredient on its label.
