Understanding Purina FortiFlora
If your dog struggles with digestive issues, loose stools, or frequent tummy troubles, chances are someone has recommended Purina Pro Plan Veterinary Supplements FortiFlora. This probiotic powder has become one of the most trusted supplements used by veterinarians for both short-term digestive problems and long-term gut health.
But does it really live up to the hype (and the price)? I tested FortiFlora with my own dogs and compared my experience with real-world feedback from pet owners online.

What Is FortiFlora and How Does It Work?
Clinically Proven Canine Probiotic
FortiFlora is made by Purina Pro Plan Veterinary Diets, a vet-recommended line of nutritional supplements and diets.
Each single-serving sachet contains 8 billion CFU of Enterococcus faecium, a probiotic that helps support a healthy gut microbiome.
How It Helps
FortiFlora is designed to:
- Promote healthy intestinal balance
- Support immune health
- Reduce episodes of diarrhea caused by stress, antibiotics, or diet changes
- Improve stool quality and consistency
You simply sprinkle one packet of FortiFlora over your dog’s regular food once a day — most dogs love the flavor.
My Testing Experience
I tested FortiFlora with my two dogs:
- Bourbon, a 4-year-old Blue Heeler who tends to get loose stools from stress
- Hurley, a 9-year-old Border Collie with a sensitive stomach
Within 3 days, I noticed firmer stools and less gas in both dogs. Bourbon, who usually refuses anything powdery on her kibble, actually licked the bowl clean.
By the end of two weeks:
- Hurley's digestion had noticeably improved
- Both dogs showed less bloating and stomach noise
- Neither had any adverse reactions
It’s not magic — but it’s close.
