Purina Pro Plan
FortiFlora Probiotic for Dogs
A vet-line probiotic sachet stirred over food once a day, made for dogs with loose stools or a stomach that has been through the wringer lately. Not a fix for anything serious on its own, but a genuinely common first step alongside a bland diet.

Our take
FortiFlora is the probiotic most vets reach for first when a dog has loose stools, because it is a single-strain, veterinary-line product with real research behind it rather than a generic supermarket blend. Each sachet is a one-day dose stirred straight over wet or dry food, and most owners see stool firm up within a few days of starting it.
Good to know
- One sachet per day, mixed into food
- Single-strain probiotic (Enterococcus faecium)
- 30 sachets per box
- No refrigeration needed until opened
Who it is for
- Dogs with occasional loose stools
- Settling a stomach after a diet change or upset
Who should skip it
- Diarrhea lasting more than two days, blood in the stool, or a lethargic dog, see a vet instead of waiting on a supplement
- Dogs already on a different vet-prescribed probiotic
