Vital Planet Flora Dog (Capsule, 30 ct) vs Purina Pro Plan Vet FortiFlora (Powder packet, 30 ct)

There's no dedicated article pitting Vital Planet Flora against FortiFlora head-to-head; this pairing comes from the two showing up together in Amazon and Chewy 'frequently compared' placements, so treat it as an editorial match rather than a documented reader debate. The label gap is real either way: Vital Planet's capsule lists ten strains at 20 billion CFU with no strain codes, while FortiFlora's packet lists one strain, Enterococcus lactis SF68 with an NCIMB code, at 100 million CFU but five canine RCTs and six canine studies on record.

Stronger value rule: more strain-named organisms, CFU guaranteed through expiry over at-manufacture, and more canine RCTs each count as stronger. Raw CFU count alone never does.

Asked about this pair

Does Vital Planet Flora's much higher CFU count (20B vs 100M) make it the stronger choice?

Not by itself. FortiFlora is the one with five canine RCTs and six canine studies logged in this data; Vital Planet Flora has two canine studies and no RCTs, so the CFU gap alone doesn't settle which does more for a dog's gut.

Can you buy both on Amazon?

Yes, both have ASINs listed in this data: B00V2CAMVM for Vital Planet Flora and B001650NNW for FortiFlora.

Is this pairing based on a known head-to-head comparison dog owners actually search for?

No. There's no dedicated comparison article behind this pair in the data gathered; it's included because the two show up together in Amazon and Chewy 'frequently compared' placements. Treat the comparison as editorial context rather than documented reader demand.
