Questions & Answers

44 Customer Questions


Can a 5lb dog use this?


Is dosage (no. of tablets the same no matter size or breed of dog

Answer by ChewyMar 11, 2020
The dosage of this supplement does not depend on the weight or breed of your dog. Feed one tablet to your dog daily under the supervision or direction of your veterinarian.

why do the chew tabs contain ash and the packets don't?

Answer by ChewyMar 10, 2021
All foods will have ash. This is not an ingredient. Ash is what is left over after a product is cooked at very high temperatures, which destroys the organic material (proteins, fats and carbohydrates), and leaves behind the inorganic, non-combustible minerals known as ash.

Do they help with anal glands issues

Answer by ChewyMar 24, 2020
This supplement promotes normal intestinal health, immune system health and may help to manage diarrhea. Overall, this supplement supports digestive system health in puppies and dogs.

It helps prevent loose stool!

When we adopted Beau as a puppy, he had girardia and tape worms. That was 8 years ago. He still has gastrointestinal issues that I have to assume are related to an impaired microbiome from his worm situation. Our vet started him on this probiotic after treating the worms. We’ve tried going without it a handful of times, but the same issues keep coming back. So we will happily continue to provide this for him for the sake of solid stool! He stays very regular with this; and is otherwise a happy, healthy boy. He takes this just like he would a treat, and i give it to him at bedtime to be consistent. 100% recommend!

One supplement changed everything

I’m Baby Dog, and these FortiFlora chewables are the only thing standing between me and a return to eating dirt and blasting farts like a fire-breathing dragon. Since I started taking these, my gut’s in check, I’ve kicked my dirt addiction, and I poop like royalty. You stop buying them? I’m lawyering up. I know people. Purina, don’t ever stop making these. I’ve never felt better. My mom’s nose has never been safer.

A great probiotic!

I’ve used this for my elderly, diabetic beagle mix for about a year now. He has a complicated health history with uncontrolled diabetes. There are a lot of restrictions

I’ve used this for my elderly, diabetic beagle mix for about a year now. He has a complicated health history with uncontrolled diabetes. There are a lot of restrictions for food and treats for him which have affected his bowels resulting in emergency vet care more than once. Consistent diet, along with these probiotics have changed the game for my sweet little pup in the best ways! His poops are consistent now. His appetite is strong and healthy again. His skin and coat are in great condition. In an attempt to simplify his daily medication, treatment, and care regimen, I tried to stop the probiotics. Within 2 days, his stool was hard and difficult for him to pass. I’ll keep him on this for the rest of his life. If you’re looking for a good probiotic, I highly recommend this one!

does it work? extremely well for my boy with a sensitive stomach. will I keep buying it? yes, but dang is it pricey. also my dog will not eat the tablet and for reasons I do not understand, they package the powdered version in individual doses which both makes it even more expensive than the tablet but also creates more waste. I wish they would just sell it in a container with a scoop. until then, I'm going to keep buying the tablets and grate them into a powder I can add to some pumpkin so my dog will eat it because it does work really well and I've even recommended it to a friend with a dog who is currently having chronic diarrhea

FortiFlora!

Been giving this to my 5 yr. old, 48 lb., mixed breed dog for 6 months. It seems, in general, to keep her stools regular and right. She didn't have a consistant problem, but has had some worrisome occurances which I could find no reason for. She does take some meds, but I don't think that's relevant. I give her one every night now, and although I feed her high quality food, (that's another review), dry kibble, that claims to include probiotics in the mix, I feel better knowing that she gets this supplement every mealtime, like I do every night :) And, I just put in in her dinner, and she eats it happily, like it's a treat. And, I can give it to her out of hand, and she'll eat it like that too. Of course, she's not a finicky eater :)

Great alternative to the sachets

I was a bit surprised at how large these pills were, but I gave it a try because my 15 lb dog started refusing to eat his food when I used the Fortiflora sachets

I was a bit surprised at how large these pills were, but I gave it a try because my 15 lb dog started refusing to eat his food when I used the Fortiflora sachets. He used to love the sachets, but then he must have gotten tired of them. So far, he seems to really like these.

Benson’s belly loves these!!

My Bernese has had such a horribly sensitive stomach since I got him around 9 weeks old. I implemented the powder PPP Probiotics a couple months ago but just hated

My Bernese has had such a horribly sensitive stomach since I got him around 9 weeks old. I implemented the powder PPP Probiotics a couple months ago but just hated the powder and having to be so careful to not spill it or have it dust my countertops. These pills are so much easier to use!! I also love that they come in a 90 day supply. Gives me one less thing to remember for a bit. These probiotics have helped Bensons bowel habits tremendously! Benson used to poop 3x every couple of hours. Now he only has one good size, healthy BM a couple times a day; usually only after eating. It is a HUGE relief for this busy single mama of 4 and full time pediatric nurse. While I love my pup immensely, no one has time for 3 loose BMs every walk every few hours! I’m so grateful for this product and highly recommend it if you too don’t have 3 poops every 3 hours kind of time! Most importantly, I’m just thankful my big ol baby feels so much better using this probiotic!

Works well but count the pills when they arrive!

This has helped keep our puppy's gut in a better place; however, you need to be careful to count the pills when they arrive. There are supposed to be 45. My order

This has helped keep our puppy's gut in a better place; however, you need to be careful to count the pills when they arrive. There are supposed to be 45. My order was delivered on 12/29/25, and I started the bottle on 12/30. I gave only 1 per day, and I have run out today, 1/29/26. That's 31 days of pills. I was shorted 14 pills! Which is nearly a third of the bottle! I will be counting them when my next order arrives, so I can report if I am shorted and get a refund.

So much easier

After recent bouts of diarrhea, with negative parasites on exams, my vet recommended Fortiflora for both my pups. A friend had some packets she didn’t need anymore

After recent bouts of diarrhea, with negative parasites on exams, my vet recommended Fortiflora for both my pups. A friend had some packets she didn’t need anymore and gave them to me. What a pain! But, they seemed to work so I went on to Chewy to order more. Then I saw they come in a tablet form! Expensive, no more so than the packets, but much more friendly packaging. Not to mention there’s no concern about spilling some, not getting it all out of the packet, or a pup not eating it all. They each take a tablet after dinner and they look forward to this nightly treat! I’m hopeful I can STOP using them soon because they are pricey, but we’ll have to see how it goes.

An absolute necessity

Our poor little Lab pup came to use with all kinds of GI challenges. It has taken us 2 months to finally get her gut settled and I attribute it at least in part to the use of this supplement. So easy to give, tastes great (at least she is more than happy to gobble it down), and works better and faster than the other poop supplements that we tried. House training a pup is not easy when they have diarrhea! Thank goodness we are over that now!
