Fi is the brand this site trusts to tell us where a dog is on a trail, not what’s in his food bowl. We put the Fi Series 3 collar up against Tractive earlier this year and landed on it as the pick for multi-day backpackers who can’t charge a collar nightly. So it’s a strange one to report that on Sept. 3, 2026, Fi recalled two of its dog supplements — Calming and 8-in-1 Formula — after learning an ingredient from its manufacturer could carry Salmonella. The FDA published the notice Sept. 8. Nobody covering gear for trail dogs has flagged this yet, and it needs flagging, because it’s the fourth dog food or supplement recall in about six weeks, following Adequan’s glass fiber recall in July, Fromm and Oma’s Pride in mid-August, and Northwest Naturals on Aug. 28.

Fi launched its supplement line as an extension of the same “know your dog better” pitch that sells the collar — daily chews meant to sit next to the tracking app, not replace a trip to the vet. That’s exactly why this recall matters to readers here even if you’ve never fed your dog a supplement in your life. If you own a Fi collar, you were already inside Fi’s marketing funnel for this product. Worth checking the pantry.

What’s Actually Recalled

Two products, both 180-gram containers, both daily supplements rather than a full diet — which is a different risk profile than a recalled bag of kibble your dog eats three times a day. The Fi Calming Supplement for Dogs is a chew built around CBD, magnesium, valerian root, and L-theanine, aimed at anxious or restless dogs. That’s Lot 26118, UPC 8 50064 80011 1.

The Fi 8-in-1 Formula Supplement for Dogs is the broader daily multivitamin in Fi’s lineup — 19 active ingredients pitched at skin, digestion, joints, muscle, brain function, heart, and kidney and liver support. That’s Lot 26159, UPC 8 50055 11168 4.

Both were sold nationally, both direct through Fi’s own site and through Amazon and Chewy.com. That distribution pattern is worth sitting with for a second: a subscribe-and-save Chewy order or an Amazon auto-ship means a bag can keep arriving on a schedule without anyone re-checking the lot number each time, unlike a one-off pickup at a local store.

Is My Fi Supplement Recalled? Quick Checklist

1. Confirm you’re feeding one of the two named products. If it’s not the Calming Supplement or the 8-in-1 Formula, this recall doesn’t apply to you today — Fi’s Hip & Joint and Skin & Coat lines aren’t named in the notice.
2. Find the lot number, usually printed on the bottom or back of the container near the manufacture or best-by date.
3. Match it against Lot 26118 (Calming) or Lot 26159 (8-in-1 Formula).
4. Cross-check the UPC as a secondary confirmation — 8 50064 80011 1 for Calming, 8 50055 11168 4 for the 8-in-1.
5. If either matches, stop feeding it today, regardless of whether your dog has had zero reaction to it so far.

Salmonella Symptoms in Pets and Humans

Salmonella in dogs can look like nothing at all — plenty of dogs shed the bacteria without ever getting visibly sick, which is exactly what makes a lot-number check more useful than a wait-and-watch approach. When symptoms do show, per the FDA notice, they include lethargy, diarrhea or bloody diarrhea, fever, and vomiting. Some dogs get a quieter version instead: decreased appetite, fever, and abdominal discomfort with no dramatic GI signs at all.

Humans handling the product face their own exposure. Symptoms in people run nausea, vomiting, diarrhea or bloody diarrhea, abdominal cramping, and fever, with rare complications like reactive arthritis in more serious cases. Wash your hands after handling either product, wipe down the counter or bowl area it touched, and treat a chew supplement with the same hygiene you’d use for raw food — not something people usually think to do with a small daily treat.

The Fourth Recall in Six Weeks

We’ve now covered four of these since late July: Adequan’s glass fiber contamination in an injectable joint drug, Fromm’s metal fragments in canned pâté, Oma’s Pride and Northwest Naturals’ Salmonella-contaminated raw diets, and now Fi’s Salmonella-contaminated supplements. Four different companies, three different contamination types, one six-week window.

I don’t think this is a raw-food problem anymore. That was a defensible read after Oma’s Pride and Northwest Naturals — raw diets carry a structurally higher baseline Salmonella risk, full stop, and two raw-specific recalls in three weeks tracked with that. Fi’s product isn’t raw. It’s a dry chew supplement, shelf-stable, nothing like a frozen raw diet’s risk profile. Salmonella showing up there points at an ingredient supply chain problem, not a category problem — something upstream, in whatever raw material got mixed into the chew, not in how Fi formulates or packages the finished product.

Whether that’s four unlucky companies drawing from four unlucky suppliers, or the FDA running hotter sampling programs across pet products generally right now, is genuinely hard to say from outside. What isn’t hard to say: four recalls in six weeks is enough of a pattern that “I’ll check the lot code next time” has stopped being an adequate plan for anyone feeding a dog something out of a bag or container.

A GPS Collar Company Selling Supplements Is a New Kind of Risk to Track

Adequan, Fromm, Oma’s Pride, and Northwest Naturals are all companies whose entire business is animal health or nutrition. Fi’s isn’t. Fi built its reputation on hardware and a subscription app, then extended into supplements the way a lot of direct-to-consumer brands extend into adjacent categories once they have an email list and a subscribe-and-save button.

That’s not automatically a red flag — plenty of pet brands cross over from one category into another without incident. But it does mean the quality-control muscle a company has built for manufacturing GPS trackers isn’t the same muscle it needs for sourcing supplement ingredients, and a recall this early in a new product line (Fi’s supplements are barely a year old as of this recall) is worth remembering the next time a gear brand you trust for one thing pitches you on something else entirely. Trusting a brand’s core product doesn’t automatically transfer to trusting everything with its logo on it.

What to Do If You Have Either Product

Stop feeding it, even if your dog has been taking it for months with zero issue.

Don’t just toss it if pets or wildlife can get into your trash. Seal the container and dispose of it in household trash per the FDA’s instructions, or contact Fi about a refund.

Watch your dog over the next several days for the symptoms above — Salmonella doesn’t always show up same-day.

Call your vet if anything beyond mild symptoms appears, and tell them it’s tied to this specific recall so they know to consider testing rather than treating blind.

Report it to the FDA through the Safety Reporting Portal if your dog gets sick, even mildly. Fi can also be reached directly at 1-888-434-3647 (10 a.m.–8 p.m. Eastern, seven days a week) or support@tryfi.com.

If Your Supplement Isn’t on This List

You’re fine to keep feeding it. This isn’t a reason to write off Fi’s supplement line entirely any more than the Fromm recall was a reason to swear off canned food — a recall caught before widespread illness reports is a sign the system caught a problem, not proof the whole product category is compromised.

What is worth adopting: check the lot code every time a new container shows up, especially if you’re on a subscribe-and-save order that arrives without you actively re-ordering. That’s the exact blind spot a direct-to-consumer recall like this one exploits — nobody re-verifies a product they didn’t just go pick out themselves.

If a chunk of your dog’s daily routine just came off the shelf and you’re rethinking what’s actually worth feeding a working or high-mileage trail dog, a stocked first aid kit won’t fix a supply-chain problem, but knowing early GI-distress signs cold is the same skill either way — at home or three miles up a trail.

Bottom Line

Fi recalled its Calming Supplement (Lot 26118) and 8-in-1 Formula Supplement (Lot 26159) for dogs on Sept. 3, 2026, over possible Salmonella contamination tied to an ingredient from its manufacturer. The FDA published the notice Sept. 8. No illness count is listed in the notice either way. It’s the fourth pet food or supplement recall since late July, and the first one to hit a brand this audience knows for hardware rather than nutrition. Check your container against the lot numbers above — it takes less time than finishing this article did.
