What Loyal does
Loyal (legal entity: Loyal Animal Health, Inc.) is a clinical-stage veterinary biopharmaceutical company founded in 2019 and headquartered in San Francisco. Its mission is to develop longevity drugs that extend the healthy lifespan of senior dogs, with lead program LOY-002 — a once-daily, beef-flavored prescription pill targeting metabolic dysfunction via IGF-1 hormone reduction, a mechanism designed to mimic the effects of caloric restriction on age-related decline. The drug candidate is intended for dogs aged 10+ and weighing at least 14 lb, and three drug programs are in development across the portfolio. LOY-002 has completed two of the three major FDA technical sections (Reasonable Expectation of Effectiveness and Target Animal Safety) required for Expanded Conditional Approval, with the manufacturing/CMC section still in progress.
The company's clinical evidence base is anchored by the STAY trial — described as the largest clinical trial in veterinary medicine history — with 1,317 dogs enrolled across approximately 70 veterinary clinics. Loyal plans to commercialize LOY-002 through a direct-to-consumer prescription model comparable to Hims & Hers and Ro, complemented by its existing veterinary clinic network for prescription fulfillment and patient monitoring. Pricing has not been disclosed, and the company is pre-revenue pending regulatory clearance. Loyal has raised more than $250 million in total private capital across rounds from 2020 through 2026, most recently a $100 million Series C in February 2026 led by age1 with participation from Baillie Gifford and The Longevity Fund. Customer-facing channels beyond drug distribution include the Loyal Learning Hub, a RACE-approved continuing-education platform for veterinarians, plus content marketing and earned media in major national outlets.

Loyal competitors and assessment
Company assessmentBroad incumbents
- Zoetis: The world's largest pure-play animal health company, offering veterinary pharmaceuticals, vaccines, diagnostics, and parasiticides across companion and livestock animals. Zoetis is comparable as a broad incumbent that could enter or acquire into the canine longevity drug category once Loyal validates the market.
- Elanco Animal Health: Major global animal health company with a broad portfolio of companion animal therapeutics. Elanco is comparable as a broad incumbent competitor and potential fast-follower in canine healthspan / longevity pharmaceuticals.
- IDEXX Laboratories: Leading veterinary diagnostics and reference-lab company expanding into software and practice management. IDEXX is comparable as a deep veterinary-channel incumbent that controls significant touchpoints with U.S. companion animal practices.
- Ceva Santé Animale: Global veterinary pharmaceutical company with a large companion animal portfolio including behavioral and therapeutic products. Comparable as a broad incumbent with the R&D and distribution reach to compete in canine therapeutics.
- Virbac: Independent global animal health company specializing in veterinary pharmaceuticals across companion and production animals. Comparable as a mid-sized incumbent with active companion animal therapeutic franchises.
- Phibro Animal Health: Diversified animal health and nutrition company with companion animal and livestock pharmaceutical lines. Comparable as a broad incumbent operating in the veterinary therapeutics market.
Direct peers
- Hims & Hers Health: Public telehealth and direct-to-consumer prescription drug company cited by Loyal as the model for its LOY-002 distribution. Comparable on go-to-market mechanics (DTC prescription acquisition and fulfillment), not on therapeutic area.
- Ro: Direct-to-consumer telehealth and prescription pharmacy company that has built its own vertically integrated compounding and fulfillment capabilities. Comparable to Loyal's stated DTC commercialization blueprint for LOY-002.
Emerging players
- Modern Animal: Membership-based veterinary clinic chain with a digitally enabled, consumer-grade experience. Comparable as an emerging player shaping how pet owners access prescription veterinary care, a channel Loyal plans to leverage.
- Dog Aging Project: Large longitudinal research initiative studying aging in companion dogs, including the rapamycin-based TRIAD trial. Comparable as the leading academic longevity-in-dogs effort and a potential scientific collaborator or competitor for evidence generation.
