In addition, some subway stations will also open a pet consignment service, which requires you to pay the corresponding fees and make an appointment in advance. Pet consignment also needs to meet certain conditions, for example, pets need to take a closed air box and need to provide relevant veterinary certificates and quarantine certificates for pets.
To sum up, under normal circumstances, pets are not allowed to enter Nanjing Metro, but only in a few cases, and it is necessary to comply with relevant regulations and standards and pay corresponding fees. Therefore, if you want to take the Nanjing subway and have pets, you'd better check the official regulations in advance and consult the relevant departments.
