I am planning to move to China this year and definitely and will be taking Chloe with me. Oh my poor baby, she is going to be lost in translation!
A pet relocation company is help you arrange all the paperworks and everything you need when you import your pet to a different country. You cannot just move with your pet to a different county if you do not file all the necessary paperwork for your pet and vet records, etc. I know in China, every dog will have an "ID" and there is a limit how many dogs you can have in a household. It might vary province from province though.
My hubby's aunt moved with their dog from state of VA to Shanghai and they used a Pet relocation company. So they will handle all the paper work and procedure. It was a door to door service. I don't think I will need a door to door service for Chloe since I want her to travel with me inside the cabin on the plane. And she is a small dog. My aunt has a medium sized dog I believe.
Just think of a Pet relocation company is like when you (human) move to a different county, you need to file all the paperworks and get visa, etc. In a way, I think Pet relocation company is like a "lawyer" who will handle all the paper work. My aunt told me the service she paid for the pet relocation company, door to door service, was over $4000!!!
