Every day, they have about 10-15 dogs in circulation. The dogs rotate in and out of service every few days. The ones in service stay on-site in a kennel, and the rest are all kept in nearby facility on their days off. The average dog works for about 5-6 years before they retire. Once they retire, they go to a facility in Chiba where they "rest." I wasn't exactly sure what they meant by rest, but I am going to give them the benefit of the doubt and assume it means they get to romp in huge meadows with other retirees.
