We register (including all Continental Europe) our dogs with FCI, so I think you definitely need an export pedigree made. I assume you already had your dog's blood tests done and a pet passport made ;).
As for showing itself..... there's not much of a difference, though we are a bit more strict about docking our dogs. There are some judges that will not accept docked dogs in the ring.
I have a similar problem, but the other way around...... I am moving to UK in July and bringing my European dog with FCI reg. papers. Hopefully I will continue his showing career there.
