What is Purina FortiFlora?

Purina FortiFlora is the number one probiotic recommended by veterinarians in the United States. It's inevitable that at some point our pets will have some stomach issues. As horrible as it is to have our beloved pets not feel well, there is help. For years, probiotics have been known to help pets with gastrointestinal issues and to promote intestinal balance. It contains a special strain of probiotic that has been proven to promote intestinal health and balance, as well as promote immune health. Purina FortiFlora contains high levels of antioxidants such as vitamins A, E, and C, and contains a guaranteed amount of live active cultures, which all work together to give your pet excellent intestinal health. In addition, FortiFlora helps pets that have diarrhea due to stressful situations and food intolerances.

How does Purina FortiFlora work?

Purina FortiFlora contains active live cultures and a special strain of probiotics to help promote intestinal health and balance in dogs and cats. FortiFlora has been shown to be safe for use, and has excellent palatability. FortiFlora is great for any pet to help promote happy, healthy tummies. It also may help nutritionally manage pets with diarrhea due to:

  • Boarding or a change in home environment
  • Diet change or consumption of inappropriate foods
  • Soft stool in puppies or kittens
  • Recovery after antibiotic therapy

In addition, the probiotic in FortiFlora, Enterococcus Faeceium, has been shown to promote immune health. It can help promote immune system health in young pets before and during immunizations, in aging pets with weakened immune systems, and in pets experiencing weakened immune systems due to illness or treatment.

Purina FortiFlora is rated 4.8 out of 5 by 28.
Rated 5 out of 5 by from FortiFlora We have been using this product for about 4 years now for our small dog. We sprinkle a half of a packet on his dry food every few days. He love the extra flavor and we love that it keeps his tummy happy.

Rated 5 out of 5 by from Happy Dogs My local SPCA gives each adopter 7 days of this product to help in the adjustment to the new home. This works so well that I was glad to find I could order this for those times when the dogs do experience a little tummy trouble.

Rated 5 out of 5 by from Very Good Product Keeps my cat's tummy happy. I just wish it came in a jar and not little packets that come out to $1 each (30 per box). Very expensive!

Rated 5 out of 5 by from What a blessing I have used FortiFlora for about 2 years. He doesn't need it all the time, but I am so thankful that I have it on hand when he has a bout with diarrhea problem. I give it to him then and a few days after. Thank you, and if you haven't tried it - give it a try. Everything in it is good for them and sometimes their bodies get upset, just like you or me it is so wonderful to have something to help my buddy feel better fast.

Rated 5 out of 5 by from Fortiflora My cat has been on this for app.4 months now..I do not use a whole packet at one time..I sprinkle some on her food each time she eats..she has a kidney issue as well as thyroid and eats often. She turns down almost everything unless it has the fortiflora on it..

Rated 5 out of 5 by from Happy Dog...Happy Life We rescued our dog Indie back in March and put him on the same food as the others were eating (Purina Pro Choice Sensitive Stomach). He did not do well, nor did he do well on any of the other top shelf food we tried him out on. His stomach rumbled constantly and he passed gas like a trooper. Nothing helped...not even the chicken and rice diet. Our vet recommended the Purina FortiFlora and life is good again. He feels great and his gaseous emissions are no longer clearing rooms in our home. Best stuff ever!!!

Rated 5 out of 5 by from It Works! Took my cat to the vet numerous times for diarrhea. After trying other things the vet recommended a very expensive prescription food. They told me to feed him only dry food, nothing else. Right! (Sarcastic tone of voice). He loves the canned food so much. I heard about probiotics and read several of the reviews on 1-800 Pet Meds. Talked to my niece who is also a vet. She recommended Fortiflora. With the Fortiflora he has good solid stools, the right color, and can still enjoy his canned food. Pricy? Yes, but if you want to stop the diarrhea and/or loose stools, this is for you! Try it!

How long before we get results

Is it common for dogs to have soft stool during the first week using fortiflora? Shortly after every dose my dog poops and it is smelly, light in color, and soft. This only happens right after his dose. Is it just because he is adjusting? 

Asked by: Mcook64
Side effects, also known as adverse effects, are generally more likely to occur when starting treatment. Individuals may also experience side effects from Fortiflora Canine as a result of an interaction with other medications. Please contact your veterinarian if they become worse or bothersome.

Can FortiFlora be given at the same time as antibiotics, or should the two be administered separately?  If they should be spaced out, by how much?

Asked by: caelasand
I would separate the FortiFlora and antibiotic by atleast 2 hours.

Can the FortiFlora be used everyday?

Asked by: Diane
Hi there, since your vet may change the dosage amount for your pet. Always speak to your veterinarian before using since he would know your Furry Friends medical history.
