What Happened
On September 3, 2026, Vet Plus, Inc., operating under the Fi brand and headquartered in New York, NY, voluntarily recalled two 180-gram dog supplement products: Fi Calming supplement for Dogs (lot 26118, UPC 8 50064 80011 1) and Fi 8-in-1 Formula supplement for Dogs (lot 26159, UPC 8 50055 11168 4). The recall was initiated after the company learned an ingredient supplied to its contract manufacturer could carry Salmonella contamination. The FDA posted the company announcement on September 8, 2026.
The contract manufacturer has suspended production of the implicated ingredient while it investigates the upstream source. Fi is notifying affected customers directly out of an abundance of caution and has set up a dedicated consumer contact line (1-888-434-3647, 7 days/week, 10am-8pm ET) and email channel (support@tryfi.com).
The recalled products were distributed through direct-to-consumer channels and the online retailers Amazon and Chewy.com, giving the recall a wide, largely e-commerce-driven footprint. Consumers are advised to stop using the affected lots, seal the container tightly, and dispose of it in the trash. Pet owners who notice Salmonella symptoms in dogs (lethargy, diarrhea or bloody diarrhea, fever, vomiting, decreased appetite, abdominal pain) after use of the recalled product should contact their veterinarian. People handling the product or cleaning up after affected pets who develop gastrointestinal or flu-like symptoms should contact a healthcare provider.
Background
Fi operates in the fast-growing pet supplement and wearable category. The Fi subscription collar and accompanying wellness supplements are positioned as a digital-first pet care ecosystem. The brand’s supplement line includes calming, joint, digestive, and multifunctional formulations marketed directly to consumers and through major online pet retailers.
The pet supplement industry has experienced a series of Salmonella-driven events over the past several years. Salmonella contamination in pet products is considered a One Health risk: the bacteria can sicken animals that consume contaminated products and can also infect people who handle contaminated containers or come into contact with surfaces or animal waste after ingestion. The U.S. Centers for Disease Control and Prevention has previously documented human Salmonella outbreaks linked to contaminated pet food and treats, underscoring that pet-product contamination is both an animal health issue and a household exposure issue.
Ingredient-supplier concentration is a recurring risk vector in pet supplement manufacturing. The recall notice indicates the contamination was traced to an ingredient supplied to the contract manufacturer — meaning the brand’s direct QC protocols did not catch the issue at the finished-product level. This is a common pattern in the supplement industry where manufacturers rely on supplier certificates of analysis rather than in-house Salmonella testing on every incoming ingredient lot.
Industry Context
The pet supplement market has grown rapidly as pet humanization drives owners to invest in preventive wellness products. Categories such as calming aids, joint support, digestive health, and multifunctional blends have proliferated across D2C and e-commerce channels. Brands typically use contract manufacturers rather than operating their own facilities, which makes supplier qualification and ingredient-level testing critical control points.
Distribution through Amazon and Chewy means consumer awareness of the recall depends on email outreach, marketplace listing updates, and direct customer notifications rather than in-store signage. Both retailers operate dedicated pet product safety communication channels and require sellers to participate in recall notifications, but the practical reach of the recall message varies based on email deliverability and customer engagement.
For contract manufacturers serving the pet supplement category, the Fi recall is a reminder that ingredient provenance documentation, supplier qualification audits, and Salmonella lot-level testing remain critical even for established product categories. Brands that supplement contract manufacturing with internal analytical testing or that maintain second-source supplier relationships reduce the probability of being caught by upstream ingredient issues.
Market and Business Impact
For the supplement brand segment broadly, the Fi recall adds to the cumulative weight of contamination-driven recalls in 2026. It also creates an opportunity for competitors with more vertically integrated supply chains or more rigorous supplier audit programs to differentiate on safety.
For retailers, the recall creates a customer-service load: Amazon and Chewy must update product listings, manage customer inquiries, and process any refund or replacement requests. Marketplace platforms typically absorb these costs in their customer service operations and may flag the seller for enhanced review depending on the resolution.
For pet owners and the pet pharmacy channel, the recall reinforces the importance of checking lot numbers on supplements, monitoring pets for symptoms, and contacting veterinarians promptly if symptoms appear. The CDC notes that even outwardly healthy animals can be Salmonella carriers and can spread the bacteria to other pets or humans, which is why thorough handwashing after handling pet products, food, or waste remains the primary prevention measure. Pet insurance for dogs typically covers veterinary treatment of such foodborne illness, subject to deductibles.

What This Means for the Pet Industry
Pet supply chain solutions providers, particularly those offering ingredient traceability and certificate-of-analysis services, are likely to see sustained demand from brands seeking to harden their supplier qualification programs.
The Fi Salmonella recall is part of a sustained 2026 pattern of contamination-driven supplement recalls and highlights two structural concerns. First, ingredient-supplier concentration risk: contamination originating upstream from a single ingredient supplier can transmit to a finished SKU without the brand’s direct visibility, exposing how multi-tier supplement supply chains can transfer contamination downstream. Second, the rising role of e-commerce distribution as the recall notification channel: marketplace platforms like Amazon and Chewy can scale recall outreach via email and listing updates, but consumer awareness ultimately depends on those channels reaching affected purchasers.
For contract manufacturers, the takeaway is to strengthen supplier qualification programs, certificate-of-analysis review, and Salmonella lot-level testing. For supplement brands, the recall reinforces the value of in-house analytical testing, second-source supplier relationships, and clear downstream recall playbooks. For retailers, the event is a reminder to keep safety communication workflows current and ensure that marketplace listings are promptly updated when recalls are announced.
