Who regulates pet food?
Plus: VCA closes urgent care centers, Zoetis provides new information on Librela

Hello đź‘‹
Welcome back to another edition of Weekend Rounds!
It’s great to be back. We took a week off writing your favourite veterinary newsletter last weekend so we could spend time at the OVMA trade show. Thank you to everyone who came over to say hi - we loved meeting so many of you!
Today is the Super Bowl as the Kansas City Chiefs go for a their third straight championship against the Philadelphia Eagles. Since only one of these teams is an animal, I think we have to cheer for Philly. E-A-G-L-E-S! Fly, Eagles Fly!
Or if football isn’t your game maybe you’ll want to tune in to the Puppy Bowl as Team Ruff takes on Team Fluff for the Lombarky trophy. We’re suckers for a good pun, and all the dogs participating are up for adoption. Love it.
And a PSA for all you wonderful readers: Friday is Valentine’s Day so go book that dinner reservation. Or if find yourselves alone this Valentines day, consider a shelter dog sleepover.
Here’s what else we’re covering across the world of vet med:

Who regulates pet food these days?
According to reporting from VIN News, the review system for new pet food ingredients in the U.S. is currently in flux.
This follows the dissolution of a long-standing partnership between the U.S. Food and Drug Administration (FDA) and the Association of American Feed Control Officials (AAFCO) which expired on October 1 of last year. The partnership was unique in that it combined federal regulatory oversight with the expertise of a private organization. The FDA, by law, regulates food safety for both humans and animals, while AAFCO, established in 1909, traditionally set standards for animal feed and pet food, although it lacks explicit legal authority.
The partnership was formalized in 2007 through a memorandum of understanding, allowing the FDA to serve as the scientific reviewer for AAFCO’s ingredient definitions. This collaboration aimed to streamline the approval process for new ingredients, ensuring safety and efficiency. However, the FDA decided not to renew the agreement, opting instead to handle reviews independently through a new process. This shift has led to the creation of two separate review pathways: one managed by the FDA and the other by AAFCO in collaboration with Kansas State University’s Olathe Innovation Campus.
AAFCO’s new partnership with Kansas State is touted to offer a more efficient and straightforward review process, with a target completion time of nine months, compared to the years it could take under the previous system. Despite the potential for faster approvals, concerns remain about the legal standing and safety assurances of the AAFCO-led process. The FDA’s role as the primary regulator is underscored by its legal authority, raising questions about the implications for businesses and consumers navigating these dual pathways. The evolving landscape of pet food regulation highlights the ongoing debate over efficiency versus regulatory rigor in ensuring the safety of animal feed products.

Zoetis provides Librela Update
Librela has been under fire recently, and we know you’re up to speed because we’ve covered it extensively. Following large number of client complaints and class action lawsuits, the injectable monoclonal antibody designed to manage pain associated with osteoarthritis in dogs by targeting and neutralizing Nerve Growth Factor (NGF), has received new labeling.
In response to the growing concerns, Zoetis has updated the U.S. label for Librela to include detailed information about these adverse events based on post-approval experience.
Now noted on the Librela website:
Post-Approval Experience (2025)
The following adverse events are based on post-approval adverse drug experience reporting for Librela. Not all adverse events are reported to FDA/CVM. It is not always possible to reliably estimate the adverse event frequency or establish a causal relationship to product exposure using these data.
The following adverse events in dogs are categorized in order of decreasing reporting frequency by body system and in decreasing order of reporting frequency within each body system:
Neurological: ataxia, seizures, paresis, proprioception deficits, paralysis
General: anorexia, lethargy, recumbency
Urinary: polydipsia, polyuria/pollakiuria, urinary incontinence
Gastrointestinal: vomiting, diarrhea
Musculoskeletal: muscle weakness, muscle tremors, lameness
In some cases, death (including euthanasia) has been reported as an outcomes of the adverse events listed above.
Veterinarians should rely on product labels when making clinical decisions.

VCA Closes Urgent Care Centers
VCA Animal Hospitals is closing 17 urgent care practices across five states, as reported by VIN News.
This marks a strategic shift from its initial expansion plans. This decision, influenced by market conditions and client demand, aims to enhance patient care and client experience across its network. The closures affect locations in Texas, California, Colorado, Illinois, and Arizona.
VCA, owned by Mars Inc., operates over 1,000 hospitals in the U.S. and Canada. This move reflects broader trends in the veterinary industry, where urgent care models are being re-evaluated. Competitors like Bond Vet and PetMedic continue to expand, indicating a competitive and evolving market. VCA’s decision may signal a shift towards more specialized or consolidated services, or an early indicator of things to come across the profession.
