“Sammy's digestive system can be finicky, and this has kept him stable for months. Palatable enough that he doesn't notice it in his food.”

FortiFlora is the probiotic that veterinarians most commonly recommend, and for good reason, especially for Yorkies with sensitive digestive systems. This Purina Pro Plan veterinary supplement provides beneficial bacteria that help maintain healthy gut flora, crucial for Yorkies who often struggle with digestive issues, loose stools, or upset tummies. The convenient powder sachets make it easy to sprinkle the correct dose on your Yorkie's food, and most pups find the taste appealing. Many Yorkie parents turn to FortiFlora during stressful times like travel, diet changes, or after antibiotic treatments when gut health needs extra support. The probiotic helps promote a healthy intestinal environment while also supporting immune system function.

Yorkies can be prone to sensitive stomachs, and having a trusted probiotic on hand gives you a tool to address digestive upset quickly. The veterinary-grade formula means you are getting a product backed by scientific research and trusted by professionals. Perfect for daily maintenance or as-needed support during times when your Yorkie's digestion needs a boost. Keep your Yorkie's tummy happy and healthy with this vet-recommended probiotic.

What owners say

From the reviews.

Nearly 4.7-star rating across 48,000+ reviews. Overwhelmingly positive on effectiveness and digestive support (2460 and 1574 positive mentions respectively). Dogs tolerate it well—598 of 620 taste mentions positive—and it's recommended by vets. Price is the only recurring grumble: some find it worth it, others don't, but the product itself rarely disappoints when used consistently. Few dogs have neutral response; most either improve noticeably or owners don't notice change.

Customer questions

Things people ask.

Most customers report firmer stools and visible improvement within 2–3 days of starting. Some see results in under a week; others report relief from diarrhea within the first dose.

Q02. Will my dog eat it? +

Yes, in most cases. 598 of 620 taste mentions are positive. Dogs rarely detect it sprinkled on kibble, in broth, or mixed into soft food. Even picky eaters tend to accept it.

Q03. Is it vet-approved? +

Yes. This is a Purina Pro Plan Veterinary formula, and customers consistently mention vets prescribing or recommending it—especially after antibiotic use or for sensitive stomachs.

Q04. How long does a 30-count box last? +

Standard dose is one packet per day per dog, so 30 packets = 30 days. Some customers use half-packets for smaller dogs or lighter cases, extending supply to 60 days.

Q05. Does it help with gas and bloating? +

Yes. Customers report reduced gas, bloating, and flatulence alongside digestive improvements. One reviewer noted 95% less gas and solid stools within weeks of use.
