Get Joy vs FortiFlora: Which Dog Probiotic Is Right for Your Dog?

Updated: July 2026 · Reviewed against verified competitor data and Get Joy product facts · See our vet & nutrition experts

Both Get Joy Digestion Chews and Purina FortiFlora are real options for supporting your dog's gut, so the honest question is not which brand wins in the abstract. It is what actually helps your dog's gut, and which job you are trying to do. FortiFlora is built for short-term help with occasional diarrhea, while Get Joy Digestion Chews are built for everyday, whole-picture support, so if your dog just needs to bounce back from a rough couple of days FortiFlora is a sound pick, and if you want daily maintenance for the long haul Get Joy is likely the better fit.

Here is what most probiotic comparisons miss. The question is not just how many bacteria are on the label or what form they come in. It is what the product actually does for the gut once your dog eats it. That is where Get Joy takes a different path: we start with the gut, because gut health is whole-body health, and we build our Belly Biotics thinking, prebiotics, probiotics, and postbiotics, directly into the product. A single probiotic is one piece. Supporting a whole ecosystem is the outcome.

What is the main difference between Get Joy Digestion Chews and FortiFlora?

The main difference is that FortiFlora is a single-strain probiotic built largely for a specific short-term job, while Get Joy Digestion Chews are a complete daily system. FortiFlora is a sprinkle: you add it on top of whatever your dog already eats, it does its work, and for many dogs that is the end of the story until the next upset.

Get Joy takes the daily, whole-picture view. A probiotic on its own is one piece of a system. Live bacteria need prebiotic fiber to feed them, and postbiotics, the compounds produced when bacteria ferment that fiber, do a lot of the actual work of supporting the gut lining and immune balance. Get Joy Digestion Chews deliver all three together, which is the difference between adding one bacteria and supporting a whole ecosystem. And because the same Belly Biotics thinking is built into Get Joy meals, the supplement deepens a gut-first routine rather than patching over food that does nothing for the gut.

Get Joy vs FortiFlora at a glance

Here is the head-to-head on the factors dog parents ask about most.

Credit where it is due. FortiFlora is the number one veterinarian-recommended probiotic brand to support digestive health, and that reputation is earned. Its strain, Enterococcus faecium SF68, has real published research behind it and a track record of helping dogs bounce back from occasional diarrhea, often within a couple of days. Purina uses a microencapsulation process to help the bacteria survive the trip to the intestine, the powder mixes into food easily, and it is safe for puppies and adults. If your dog is having an acute episode and your vet reaches for FortiFlora, that is a sound call and we would not tell you otherwise.

Which is better for your dog's gut every day?

For daily gut maintenance, Get Joy Digestion Chews are the more complete choice, because they support the whole ecosystem rather than adding one bacteria. FortiFlora's SF68 is a legitimately well-researched strain, and single-strain products have a real place, especially for targeted short-term use with veterinary guidance. Where daily supplements differ is completeness.

Get Joy uses Bacillus coagulans and B. subtilis, which are spore-forming probiotics. That matters more than the raw CFU number: spore-formers are built to survive stomach acid and shelf storage and arrive in the gut alive, so a well-chosen 3 billion CFU that survives can do more than a bigger number that does not. Alongside the probiotics, the chew includes inulin to feed them, a postbiotic for the benefits bacteria alone cannot deliver, plus algal omega-3 (DHA and EPA) for a normal inflammatory response, L-glutamine to fuel the gut lining, and ginger to settle the stomach. If you want the science first, start with Gut Health 101 and our guide to pre, pro, and postbiotics.

What is a postbiotic, and why does it matter?

A postbiotic is a beneficial compound produced when probiotics ferment prebiotic fiber, such as short-chain fatty acids, and it is the newest and least understood piece of the gut puzzle. Most dog parents know probiotics (good bacteria) and have heard of prebiotics (the fiber that feeds them). When probiotics ferment prebiotic fiber, they produce beneficial compounds, and those compounds are postbiotics. They help nourish the cells lining the gut and support a balanced immune response.

The useful part: postbiotics deliver benefits without depending on live bacteria surviving the journey, which is why Get Joy builds a postbiotic (Saccharomyces cerevisiae) right into the chew. Classic FortiFlora powder does not include a postbiotic or, in that version, a prebiotic. You can go deeper in our explainer on postbiotics for dogs and what Belly Biotics is.

How do they compare on cost per day?

On a true per-day basis, Get Joy is easy to plan around. FortiFlora is typically bought a box at a time and used during flare-ups, so many owners are not paying for it daily year-round. Get Joy Digestion Chews run $39.99 for 90 chews, which is about $0.40 a day for a dog under 30 pounds, and Subscribe and Save is 50 percent off the first order then 10 percent off every order after. If you have been buying a probiotic plus a separate omega-3 plus something for the gut lining, the all-in-one math usually lands in Get Joy's favor. (Confirm current FortiFlora pricing on the retailer of your choice.)

Which fits real life better?

Both are easy to give, so the real question is the job, not the format. FortiFlora's powder is genuinely easy to dose and most dogs accept it mixed into food. Get Joy is a soft chew most dogs take like a treat, with no powder, pills, or droppers, which tends to win with dogs who inspect their bowl for anything new. Both store at room temperature. The real question is what you are solving for: a box in the cupboard for bad days, or a daily chew that supports the gut before the bad days start.

The final verdict: Get Joy Digestion Chews or FortiFlora?

FortiFlora is the right tool for a specific, short-term job, and it earns its vet-recommended reputation. Get Joy Digestion Chews are built for the daily job: a complete pre, pro, and postbiotic system with functional extras, made to support your dog's gut every day and to pair with gut-first meals.

Frequently asked questions

What is a postbiotic for dogs?

A postbiotic is a beneficial compound produced when probiotics ferment prebiotic fiber, such as short-chain fatty acids. Postbiotics help nourish the gut lining and support immune balance, and they work without relying on live bacteria surviving digestion. Get Joy Digestion Chews include a postbiotic; FortiFlora does not.

How long until a dog probiotic works?

It depends on the goal. For acute upset, a targeted probiotic like FortiFlora may help within a few days. For daily gut support, most Get Joy dog parents see firmer stools and less gas in about 3 to 5 days, with a more balanced microbiome building over roughly 90 days of consistent use.

Can I give my dog a probiotic every day?

Yes. Daily use is what builds and maintains a balanced gut microbiome, which is exactly what Get Joy Digestion Chews are designed for. Single-strain products aimed at acute diarrhea are often used short-term instead. If your dog is on medication or has a health condition, check with your vet first.

Is FortiFlora or Get Joy better for diarrhea?

For sudden, occasional diarrhea, FortiFlora is the vet-recommended short-term choice and a good one. If ongoing loose stools, gas, or sensitivity are the pattern, a complete daily system like Get Joy may serve better. Ongoing diarrhea, vomiting, blood in stool, weight loss, or lethargy always warrant a vet visit.

How much do Get Joy Digestion Chews cost?

Get Joy Digestion Chews are $39.99 for 90 chews, about $0.40 a day for a dog under 30 pounds. Subscribe and Save is 50 percent off your first order, then 10 percent off every order after, with free shipping over $50 on subscription.
