Does the trick!
By johnsonfarm on Jan 27, 2021
I became familiar with the product while fostering a mother cat & her kittens for the local shelter, they were having loose stool so the shelter sent this home to try (the cat formula of this product). It seemed to improve the mother cat's appetite and cleared up the diarrhea. Later, when my dog ate some bad food and ended up with "the runs" for several days, I treated it with a doggy kaopectate product followed by this FortiFlora for several days to help her recover and avoid being constipated. Now, whenever she seems to be having any gastro-intestinal issues I give her a packet in some canned food and it seems to clear everything up.

Perfect for Delicate Dog Stomachs
By WNYDogwalker on Feb 28, 2021
We give this to our nine year old female dog at our vet’s recommendation. She has had digestive sensitivities and food allergies since she was one. She loves this probiotic, and so far it has helped her maintain digestive health, I.e. no diarrhea episodes since she has been taking it. We are very pleased!

Fortiflora is working so far
By DogsCat on Feb 27, 2021 Top 250 Contributor
One of our dogs was having digestive issues due to her having no teeth - not one! So, our Veterinarian recommended FloriFlora - we mix it in her food every morning-she doesn’t even notice. Buying it from Chewy is easier since I am always ordering. Chewy.com is the best!

Hooray for bacteria
By Shari on Feb 16, 2021
My dachsie Toby has been suffering with intermittent diarrhea for about a year. The vet recommended FortiFlora to restore the good bacteria into his gut. Not only does it work well to normalize his poops, he loves the flavor of it! I just sprinkle it on his morning kibble and he laps it up.

Vet Recommended - Happy Dog
By Lorin on Mar 2, 2021
Our big boy was so sluggish and the Vet recommended this product to help counter the antibiotic side effects. Turns out when the RX was done, we continued FortiFlora and he loves it! And he is so much more like the young dog he was once!!

Immediate Relief!
By BiscuitsMom on Feb 20, 2021
We had used this product before at our vet's recommendation on our prior dog. When our new rescue began having some digestive issues, we immediately tried it and within just a few days his issues disappeared. We are now making this part of his daily feeding.

highly recommend, fixed poop issues!
By LabGirl on Jan 13, 2021
my young lab sometimes has potty issues. it is usually caused by stress or lack of sleep. because of her age, when there is a lot going on, she always has to be in the middle of it. i guess she will learn to relax with age. but when this happens, we do the chicken and rice with broth and then put this powder on top and it makes the world of difference. i recommend always having this on hand and using for at least a week. you will see improvements for sure! it is a life saver for us!

Helped my dog severe issues after super strong antibiotic treatment
By MoxxySocks on Feb 27, 2021
My dog had bad diarrhea due to very strong antibiotic treatment, and I mixed this with BeneBac in her daily food and it made a huge difference in less than two weeks time. Her poop is by far much better and no more running red diarrhea.

Great for iffy tummies
By Lisa on Feb 26, 2021
Our new senior rescue’s tummy gurgled a lot and her stool was very soft. Fortiflora has really helped with both issues. We put the powder on her food once a day and she is much better. Highly recommend.

Keeps her tummy troubles at bay
By Bailey on Feb 9, 2021
My vet recommended Fortiflora for my pup who was struggling with some tummy troubles. We top her food with this in the mornings and it keeps her poops solid and regular. It’s been a lifesaver. Plus, she loves it and gobbles it right up.
