The Fi Dog Supplement Recall: What to Check Before You Restock

In early September 2026, pet tech company Fi recalled two of its daily dog supplements over possible Salmonella contamination, according to a notice posted on the FDA's recalls and safety alerts page. If you feed your dog a daily wellness or calming supplement bought online, it's worth a couple of minutes to check whether what's in your cabinet is affected — and if you end up needing a replacement, that's also a good moment to shop for it a little more carefully than usual.

What Happened

According to the FDA notice, the recall covers two specific lots: Fi Calming Supplement for Dogs and Fi 8-in-1 Formula Supplement for Dogs. The company traced the possible contamination to an ingredient supplied by a third party to its manufacturer, which has reportedly paused production while the issue is investigated. The products were sold both directly through Fi and through major online retailers, including Amazon and Chewy.

Salmonella in a pet product is a concern for two separate reasons: it can make the animal eating it sick, with reported symptoms including lethargy, vomiting, fever, and diarrhea (sometimes bloody); and it can also be passed to the people handling the product or cleaning up after an affected dog. That second point is why the FDA's guidance on recalls like this one is usually to stop use and dispose of the product carefully, rather than simply finish the bag.

Check Your Lot Number Before Doing Anything Else

The first step is confirming whether the bag or container you have on hand is part of the recall. Lot numbers are printed on the package itself, and the FDA notice lists the specific lots covered for each product. If you bought through Fi directly, the company's order history should show which batch you received; if you bought through a marketplace listing, checking the physical packaging is the more reliable option, since the lot printed on the container is what actually matters, not the listing you ordered from.

If You Have an Affected Product

If your container matches a recalled lot, the guidance is straightforward: stop feeding it, keep the container sealed, and dispose of it in the household trash rather than continuing to use the remaining supply. Wash your hands after handling it, the same as you would with any product tied to a Salmonella concern. Fi has published a customer support line and email for questions, which is the right place to ask about a refund or replacement rather than guessing at the company's policy.

This Isn't a Reason to Swear Off Daily Supplements

It's worth keeping this in perspective: the recall covers two specific products from one company, not daily dog supplements as a category. Calming aids, probiotics, and general wellness chews remain a normal, widely used part of a lot of dogs' routines. A recall like this is exactly the kind of catch the reporting system is designed to produce — a reason to check the specific product you have, not a reason to stop giving your dog a supplement your vet has been fine with.

Buying Replacement Supplements a Little More Carefully

If you do need to replace a recalled product, or this story just has you thinking about your next reorder, it's a reasonable trigger to be a bit more deliberate about where you buy from. A couple of habits are worth building in: buy from a retailer that lists a lot number or batch code on the product page (or is willing to provide one before you order), and be cautious of third-party marketplace sellers offering a steep discount on a supplement with no verifiable seller information — that's a common way an expired, mislabeled, or otherwise questionable product ends up in a cart. None of this means the cheapest listing is automatically a bad one, just that verifying who you're actually buying from matters as much as the price when it's something your dog eats every day.

Compare Prices Once You've Settled on a Product

Once you know which supplement you're restocking with, the retailer you choose still matters for your budget. Daily digestive and wellness supplements are a recurring purchase, so the same bottle can end up costing noticeably different amounts across retailers over the course of a year, even before factoring in autoship discounts some stores offer. A recall-driven restock is as good a reason as any to check that gap before defaulting to the same source out of habit.

The Bottom Line

For most owners, this recall is a quick check rather than a crisis — confirm your lot number, stop using an affected product if you have one, and reach out to Fi with any questions about a refund. When it's time to restock, buying from a retailer that's transparent about lot tracking and comparing prices before you order are both worth the extra couple of minutes.
