petkey is a pet recovery service based in the United States, available in North America. It is the largest[1] non microchip manufacturer owned pet recovery service.[citation needed] Upon enrollment, a pet's information is documented including the pet's photograph, description and emergency contact information. If the pet has a microchip implant, that number is also documented.[2] When a registered pet is lost or stolen the service sends a bulletin to members, shelter groups, veterinary clinics, trainers, pet supply retailers, and grooming shops in a 50-mile (80 km) radius[3] of the pet's last known location.[4]
