At Chewy, it is our mission to become the most trusted and convenient online destination for pet parents and our partners – vets and service providers – alike. Our success is measured by the happiness of the people and pets we serve, not simply by the amount of pet supplies we deliver. That’s why we continue to think of outside-the-Chewy-box ways to delight, surprise, and thank our loyal pet lovers!
