Fortiflora is a single-strain probiotic supplement for dogs made by Purina that is commonly recommended by veterinarians. While effective for many dogs, it contains only one strain of bacteria and some controversial ingredients, leading many pet owners to seek out multi-strain, all-natural alternatives.
While it is a popular and clinically studied probiotic it only contains a single strain of bacteria. It also includes controversial ingredients like animal digest which some pet owners prefer to avoid.
A diverse blend of beneficial bacteria strains creates a more resilient and balanced gut ecosystem. Different strains have different jobs like fighting pathogens or reducing inflammation.
Look for high quality powder supplements with multiple strains or whole food sources like plain yogurt. These options provide a more comprehensive approach to your dogs gut health.
Products like Ruff Greens VitaSmart offer multiple probiotic strains alongside essential vitamins minerals and digestive enzymes. This provides total body health support rather than just a single purpose probiotic.
FortiFlora is one of the most popular and widely recommended probiotic supplements for dogs on the market. Made by Purina, it comes in a box of 30 single-serve powder packets and is designed to support digestive health. Its primary active ingredient is a single strain of beneficial bacteria: Enterococcus faecium SF68.
Veterinarians often recommend it for managing diarrhea, supporting gut health during antibiotic use, and for dogs in stressful situations like boarding or travel. Its convenience and clinical backing make it a go-to for many veterinary practices.
FortiFlora works by introducing a guaranteed level of live SF68 microorganisms into the dog's gut. This single strain has been shown in studies to help promote a healthy intestinal microflora, manage diarrhea, and support a healthy immune system. The powder is flavored with animal digest to make it palatable for dogs, and it is simply sprinkled over their food once a day.
While FortiFlora is effective for many dogs, it’s important to look at the full picture. Here’s a breakdown of the advantages and disadvantages:
| PROS | CONS |
|---|---|
| Clinically Studied:Proven effective for canine digestive health.Veterinarian Recommended:One of the most trusted and recommended probiotics by vets.Convenient:Single-serve packets ensure a consistent dose.Palatable:Most dogs readily eat it due to the animal digest flavoring. | Single Strain:Can’t provide the same comprehensive support as a multi-strain formula.Contains Animal Digest:A controversial ingredient many pet owners prefer to avoid.Made by Purina:Some pet owners are wary of supplements from large processed pet food manufacturers.Only a Probiotic:Doesn’t provide the additional vitamins, minerals, or omega fatty acids of an all-in-one supplement. |
As noted in Dogs Naturally Magazine, some holistic vets argue that because of these drawbacks, pet owners should "skip the FortiFlora and go natural" [1].
For pet parents seeking a more natural, comprehensive approach to their dog's gut health, there are several excellent alternatives to FortiFlora.
Think of your dog's gut microbiome as a rainforest. A single strain of bacteria is like planting only one type of tree. A multi-strain probiotic, on the other hand, is like planting a diverse range of trees, plants, and flowers, creating a more resilient and balanced ecosystem.
Different strains of probiotics have different jobs. Some are better at fighting off certain pathogens, while others excel at producing specific vitamins or reducing inflammation. By providing a blend of several well-researched strains, you give your dog's gut a more robust toolkit to maintain balance and support their overall health.

1. Is FortiFlora safe for dogs? Yes, FortiFlora is considered safe for most dogs and has no major reported side effects. However, it is not recommended for dogs with severely compromised immune systems.
2. How is Ruff Greens different from FortiFlora? Ruff Greens is a comprehensive, all-in-one nutritional supplement, whereas FortiFlora is a single-purpose probiotic. Ruff Greens contains multiple strains of probiotics, plus a full spectrum of vitamins, minerals, digestive enzymes, and omega-3 fatty acids. It is also made from natural, whole-food based ingredients without the use of animal digest.
3. Can I use FortiFlora and Ruff Greens together? There is no need to. Ruff Greens already contains a powerful blend of probiotics, so adding FortiFlora on top would be redundant and an unnecessary expense.
