I don't know. By boat. I fly. It's easy. I brought my dog here a few days ago. I started from Shenyang and landed at Incheon Airport. After landing, the dog is waiting for me. I don't need isolation. I can just take it away. The detailed process is like this. First, go to the animal quarantine department of your local inspection and quarantine bureau to ask about the specific process. They will tell you the designated place for rabies vaccination, and then take the second injection every 20 days after 1 injection, and then you can book a plane ticket. When booking a plane ticket, please say hello if you can bring pets. I took Korean Air, the fare was more expensive than others, but the service was very good. Call the reception desk of your flight and reserve your pet's aerobic cabin/0/0 days before your departure. He will ask you what kind of pet you are, its weight (including the air box, if your pet's weight plus the air box is less than 5 kg, you can take it directly to the cabin), its size, departure time and so on. Call again the next day to confirm whether the application is approved, and finally, within 7 days of your departure. The rabies vaccine for pets going abroad will take 1 month to leave, so just give it a vaccination certificate in advance. Take some photos of 1 inch pet when vaccinating, and he will issue you a pet immunization certificate. Bring your immunization certificate and passport to the quarantine bureau before you leave. When you arrive at the airport, the staff will weigh your pet and charge you. The day I left was 1 kg, which was $7. In addition, the immunization certificate issued by the dog, that is, the certificate needed when flying, was collected from the signature page on the first page and used to carry the dog in Korea. That's it. Maybe you will encounter other problems. Don't lose heart. When you get off the plane and see the dog, you will know that the previous troubles are worth it! !
