Having lived overseas much of my life, to include with pets, all I can say is that the regulations for bringing pets out of a country are established by the the country you are leaving. SO what the US says you need to do to bring a dog in does not necessarily add up to the documents you need to get the pet out. It was far easier for us to take 3 cats out of the US to Korea than it was to get the necessary permits to take two of those same cats out of Korea to the US.
