What The Pet Apothecary does
The Pet Apothecary, founded in 1999 in Milwaukee, was a PCAB-accredited veterinary compounding pharmacy serving companion animal veterinarians with customized formulations, commercial medications, and OTC products. In 2024 the company was acquired by Mixlab and rebranded under the Mixlab name, becoming the Midwest anchor of a national veterinary pharmacy platform.
The integrated entity provides compounded, commercial, and over-the-counter medications for companion animals, plus extended coverage into large animal (equine, livestock), wildlife, zoo, and aquarium species following the May 2024 acquisition of Nexgen Animal Health. Distribution is handled in-house with free next-day delivery to all 50 U.S. states. Core technology includes the eMix digital prescribing platform, which integrates with veterinary practice workflows and is powered by the Maisy AI engine for prescription automation, dosing recommendations, and clinical knowledge retrieval. Quality and regulatory positioning rests on PCAB accreditation, LegitScript certification, and BBB accreditation.
The business model is prescription-driven: veterinarians issue prescriptions through eMix (or traditional channels), Mixlab compounds and dispenses the medication, and revenue is generated per filled prescription across thousands of veterinary customers. The customer base spans enterprise networks (Thrive Pet Healthcare, ACCESS Specialty Animal Hospitals), mid-market specialty clinics (Bond Vet, Behavior Vets NYC), startup-stage providers (The Vets), independent practices, and zoological institutions. Geographic operations now extend from the Milwaukee headquarters into offices in New York, Los Angeles, Florida, and Texas.
