http://www.aphis.usda.gov/regulations/vs/iregs/animals/downloads/ee_an_%20non_com_pet.pdfFirst, take a deep breath, print out everything you need, write notes, make lists! You need to know what needs to be done so you can make sure your vet does it correctly!
Step 1
Microchip with a 15 digit chip
Step 2
Rabies vaccination, you also need to have a rabies vaccination certificate from your vet
Step 3
Bring pets to vet for health certificate (needed for the airline)
Step 4
Call the USDA State Vet. office for an appointment to bring the Annex II/Third Country Vet. Cert. & Health Cert. (needed for airline) for signatures. You can also ship the paperwork to the vet for signature, but call the office first!
I called my (New York State) USDA Vet. office yesterday for an appointment, they were very helpful, I am sure your USDA State vet's office will be able to answer any questions you might have also.
Step 5
Have the tapeworm treatment done
Step 6
Ready your crates for travel as per your airlines guidelines
** When your paperwork is complete, it might be a good idea to get in contact (email/phone) with the animal reception center of whichever UK airport you are flying into & ask if you can email/fax them your paperwork so they can look it over. If there are any problems you can take of it before your flight. That way you can fly with your pets relatively worry free
