As our standard of practice, we do not directly approve prescriptions, food or medications through most third party vendors, simply because we cannot confidently guarantee that the items sold by them came directly from the manufacturers. There are, however, some pharmacies we know for certain work directly with manufacturers, guarantee their products, and keep pricing competitive. We are able to prescribe and approve prescription orders directly through Covetrus (formerly Vets First Choice), Blue Rabbit (Wedgewood compounding pharmacy), Hill's to Home, Purina Pro Plan Vet Direct, and Koala Health.
