Sorry, can't answer your questions, but thought I'd share my experience.
We moved our 11 yr old pup dog over to England last year when we relocated. After trying for a while to work out the details of the process and documentation I decided it would be better to enlist the aid of a pet relocation service to help. We settled on Air Animal and it was a great decision for us. I'm sure there are other services who are equally capable but Air Animal impressed us with their professionalism, track record and empathy for us and our pup.
I felt that the expense of their service was justified by the peace of mind we got from knowing that all vaccinations, blood tests and forms would be done correctly and on schedule. Your mileage may vary. Our experience turned out to be fantastic, the move was easy and fairly stress-free.
