Quarantine
I made some research regarding the quarantine regulation for dogs that Japanese government made. First of all, dogs have to have a microchip on their body for its ID. Second, they have to get a rabies shot twice after getting microchip. Then, after doing blood exam, they have to wait for 180 days.
If I complete this process, Luna would wait up to 12 hours at a quarantine station.
In addition to that, I have to ask my doctor to fill in some document that I will submit to a quarantine officer. I have to get an endorsement from the US government before I am traveling. We still have several process to complete.
I am also doing some research regarding dog-friendly airline companies and will write about it near future.
