You can either put things in the hands of a shipping company, or do it yourself.
Your first step is to go on the DEFRA website and find which airlines and routes are approved from the nearest departure point.
If you come through Heathrow it will cost you some £500 charges on top of the Airline Cargo charge, as they pick up, take through customs and put them in their Quarantine kennels and charge for two days boarding regardless of how short a time the dog is with them.
What you want really is a direct flight to avoid the dog needing to be transfered.
The boy my friend imported and I organised came from JFK (New York) using Delta to Heathrow. Now from other parts of the USA Delta have had a poor rep with dogs going missing, but we have used them twice, once in the old 6 month Q. days, and once with straight pick up under Pet Passports.
It does seem that charges are not so bad if flying into Manchester. If accompanying the dog on same flight, it can work out cheaper to fly them as excess baggage to closest mainland Europe hub (we came back with our bitch via Brussels) and drive back to UK.
So basically a lot of ringing around comparing possibilities, or simply opt for a good company that does it all for you. We have used Overhill from Bristol for exports, excellent again, as proper dog folk.
