life saver

My rescue pup had runny poops since we got her (4 months ago) we took her to vet for it and they said she was perfectly healthy so we had to play detective to figure out what the problem was. We switched her food, limited her treats, tried it all. We were recommended to try this and after putting one packet in her morning kibble for a few weeks she has had nothing but solid poops! Won’t go without this probiotic daily

First let me say the delivery was exceptional. I had expected to wait 3 days for normal delivery .... it was here the next morning and I'm on the east coast. WOW!! After doing a lot of research and being very familiar with Purina, I ordered this for our 8 year old shitzu (SAM), who is a rescue and we are the second set of rescue owners since the original became completely disabled & unable to care for him after we had helped out with his care for 2 years prior to getting him permanently. He never had any health issues until a few weeks ago when he went from shitzu to dzu if you know what I mean. Clean up in aisle 2,3 4. He never had accidents indoors until this. This went on for a week and we became concerned, being on fixed income and just getting hit with a $200 per month increase in rent, we could not afford to take him to a vet - so I did my research and ordered this probiotic. It only took 2 days of putting this in with his food before he was almost back to his normal, happy shitzu self. <BIG SMILE> After a week he was as good as new. Very happy and would recommend this product. Discontinued giving it to him after a week and he seems ok but will give him half a packet once a week just to keep him safe. IMOP it is worth the price and a lot cheaper than a visit to the vet. Thank you CHEWY's for great service. You gave Sam back his smile.

Worth a try!

My vet recommended this product for my 8yr old golden retriever. He gets anxiety with loud noises like fireworks, or thunder. After an episode, stomach upset always follows. This probiotic has really helped alliviate loose stool. I take a probiotic myself, so makes sense that my pups need one too! Happy with the results! Individual packets are so easy to sprinkle over food. No water required. My dogs love it!

Helpful Product

This is always a great product for any digestive issues. Currently, my elderly dog has been not wanting to eat, so I'm simply using FortiFlora as a very safe way to add enticing flavor to her food. She has too many food allergies and ingredient sensitivities for me to just use any type of flavor additive. With ForitFlora, I know I'm giving her something healthy and overall beneficial, while also getting her back to gobbling up each meal.

Smells like beef bouillon- dog won't eat it

I was really excited to try this instead of the Proviable capsules. My dog didn't hesitate to eat her food with the Proviable capsules but will not touch this stuff. There's small white specs dabbled throughout the brown powder which makes me question if there's even enough probiotic in the packet; compared to the amount of brown powder that smells like beef bouillon. It has not helped her diarrhea as much as the other. Quite disappointed for the cost.

Amazing product

I’m not somebody to write a review but this product saved my sanity. Lola had diarrhea and I was given this product (5 packets) and metronidazole. The issue was resolved. Then a couple of weeks later she had to go on some more meds for arthritis. She is a thirteen year old relatively healthy pittie girl but this has been an issue. The meds hurt her stomach. More metronidazole and it worked but not for long. I put her on a home made diet and fortiflora. Problem solved. She is doing fantastic and we both can sleep at night. Highly recommend!

Tear stains gone

I tried everything to get rid of her tear stains. I started giving her the Fortiflora while she was on an antibiotic. The vet said she could continue taking it to keep her regular and improve gut health. Not only does it keep her regular but her tear stains are gone.

Great product

We bought this because our dog was chewing hot spots on his from legs, we assumed from seasonal allergies. I began reading other posts about this product from one’s who said it treated their dogs gut problems so I decided to give it a try. I worked ! He stopped chewing and with this sprinkled on top, he eats his food as soon as we set it out for him.

Great for sensitive bellies

This has been extremely helpful for my dog who has a very sensitive stomach. Definitely helps to keep his stool firm. I know the brand is often frowned upon, and I feed a different high quality food, but nothing was really helping long term until we added this to his food.

Great product for dogs and cats with digestive issues

I started using FortiFlora years ago when I was fostering kittens for a local humane society. Back then it was by prescription only and my vet provided it. The foster cats and kittens loved it. Now I have a Miniature Pinscher and a Yorkie mix who both have sensitive stomachs and occasionally end up with digestive issues and so I always keep a box on hand. It's very easy to use. It comes in individual packets and you just sprinkle the contents of one packet on their food and mix it in. Even picky eaters will love this added to their food. It really does the trick. It's a probiotic and it works great.
