Dogs can be brought on the high-speed train. The owner only needs to check in the dog when entering the station, so that the dog can take the same high-speed train with the owner to reach the destination. The dog will be placed in a special carriage until the destination. The owner of the land must collect it promptly. When you want to check in your dog, you must prepare the epidemic prevention certificate and physical examination certificate, and then you can take the dog to the subway to go through the check-in procedures.
