Worked fast for diarrhea and picky dogs actually eat it
I bought Purina Pro Plan FortiFlora after one of my dogs started having loose stools out of nowhere. Within 24–48 hours, there was a noticeable improvement, and by day 3 everything was back to normal. I’ve since used it a few times during diet changes or after stomach issues, and it’s been consistent every time. What I really like is how easy it is to use. The individual sachets are convenient, and the powder mixes right into food. Both of my dogs are picky and had zero issue eating it—no turning their nose up, no skipping meals. That alone is a big win. I also appreciate that this is a vet-recommended product with a specific probiotic strain, not just a generic supplement. It feels like something that actually does what it claims instead of being marketing fluff. Downside: it’s not cheap, especially if you’re using it long term. That said, for acute stomach problems or stress-related diarrhea, it’s worth the price and works faster than anything else I’ve tried.

Best probiotic for antidiarrhea anti-constipation & gut health you can buy.
This stuff is amazing. I used it on my 15-year-old dog she had kidney disease and bouts of diarrhea, it cleared that up within 2 days of use. I now use it on our 10 ur old rescue who has issues with constipation and gas. She weighs 60 lb. I use a half a packet a day innthe AM and it makes her poop perfect. Sounds silly but she had a hard time pooping and now she doesn't. It is a little costly. I'll admit I used a ½ packet to see if I could get away and guess what, the half a packet works perfectly. She now goes 2xs a daily and its normal. No more hard poops, gas or bloating. We tried everything prior to this. Every food etc. I only used a ¼ packet for my 8 lb dog so that made that 30 packets last about 4 months. I get 2 months out of one box for my 60 lb very muscular elderly dog. Shes much happier now. A side note : her breath is better too. Buy this now...You won't regret it. I have tried others. They don't work. This works in 1 -2 days. Better appetite, her coat is glossy black and soft. Her skin has improved too. She had yeast feet. Not anymore. Its powder and I mix it with a bit of water into her food. I am not paid to write this.

A Game-Changer for My Dog’s Digestive Health
Purina Pro Plan Veterinary Supplements FortiFlora has been an absolute lifesaver for my dog’s digestive health. After dealing with intermittent loose stools and a sensitive stomach, our vet recommended FortiFlora—and the difference was noticeable within just a few days. What I love most is how easy it is to use. The single-serve packets are perfectly portioned, mess-free, and simple to sprinkle over food. My dog actually loves the taste and eats every bite, which is a huge win with a picky eater. No forcing, no mixing tricks needed. Since starting FortiFlora, my dog’s stools are consistently firm, digestion is noticeably better, and overall gut health seems much more balanced. I’ve also seen improvements during stressful situations like travel or dietary changes, where stomach upset used to be a problem. I appreciate that this supplement is vet-recommended and backed by science, containing a proven probiotic strain that supports intestinal health and immune function. It’s reassuring to know I’m giving my dog something safe, effective, and trusted by veterinarians. While it’s slightly more expensive than generic probiotics, the results make it 100% worth it. This is now a permanent staple in our dog care routine, and I always keep extra packets on hand just in case. Highly recommend FortiFlora for any dog with a sensitive stomach, occasional diarrhea, or digestive issues.

Packaging choices for shipment
I give this to my sheep-a-doodle, for his sensitive tummy. It works great for cut health. Now all I need roll is for Amazon to package the Purina box, in a better way now. A few times I have ordered and it always ends up smashed, when they put it in an envelope. The sachets are still usable I have never had one break open. Hence the review so that Amazon can pack it better. Thanks, Purina for a good product to help with doggy digestion. Amazon, think twice about package choices before you ship it!

I Am Purchasing Again!!!
I purchased this product for my German Shepherd. He was itchy and skin was irritated and everything I was trying failed. Thor has been taking this 14 days. The change is amazing! No itching, his coat is softer and becoming shiny again. His eyes are bright and he just acts like he feels so much better. He plays and has energy like he use to before this started. His digestion is improving. He just had his 5th birthday January 9,2026 and weighs about 125 pounds. My husband and I are amazed but ashamed because we didn’t realize he was feeling so horrible. I sprinkle it on his food in the morning and he eats it like he enjoys the taste. I now have this on subscribe and I am thinking about adding it to our Belgian Malinois feeding routine. I highly recommend this product. It is very effective. Some may not have the same results as we have.
