I wish there had been a concise list of steps for bringing pets into the EU/UK when I was planning this trip so for others who may be planning a similarly ridiculous endeavor here is such a list. You probably don't want to read this unless you're trying to get a pet passport as it's a long, boring, bureaucratic process. Here we go.
1. Because there are specific time windows for the various vaccinations book your trip first and book your pet/s a spot in the cabin ahead of time so you know exactly when you're leaving.
2. First things first. Start this process no less than 21 days before your pet's arrival in the
EU/UK. The rabies vaccination must be no older than 1 year and no newer than 21 days.
WAIT!!! Before, BEFORE, BEFOOOOORE you get the vaccination you must get a
microchip. Any rabies vaccination that is given before the microchip is fitted is
automatically invalid. The microchip must be ISO standard, an internationally recognized type which conforms to the readers they have at customs. If your pet already has a
microchip that is not ISO you can get a new one or bring your own reader.
3. Once you have a microchip and a rabies vaccination (in that order!) you are ready for the
next step which must occur between 1 and 10 days of your arrival in the EU/UK.
4. Find a USDA certified veterinarian. Inexplicably, there is no database to tell you whether
the vet is certified or not, you have to ask.
5. Have the USDA certified/federally accredited veterinarian fill out the applicable health
certificate. This is called the Annex II form. You can print it out online or have the vet
office print it. Take the original copies of the rabies documents as proof that they are
vaccinated.The vet will read the microchip and record it on the certificate and will verify
that the pet has been vaccinated against rabies. They will also include other relevant details
like the type/color/breed of the dog. NOTE! Make sure that the vet fills out the certificate and signs it in BLUE INK ONLY. This is a requirement.
6. Take the completed health certificate to a FedEx office and mail it overnight via certified
mail, remembering to use a tracking number so you can keep an eye on it. Also include in
the envelope: a prepaid overnight return envelope so they can return it to you once it's
stamped, a check for the payment for the stamp (I believe it was around $30.00 per pet but this varies by state so check), put your driver's license number on the top of the check.
7. Shortly it should be returned to you, stamped. If you are going into the EU you are ready to go at this point. If you are going into the UK there is one more important step.
8. UK only: between 24 and 120 hours your pet is required to receive treatment for
tapeworms. The veterinarian administering the treatment must record all the relevant
information including date and time of the tapeworm treatment.
9. Make sure you purchase an airline approved pet carrier that will fit the under-seat
dimensions, which may require calling the airline and getting measurements. Call the airline 48 hours ahead of your flight to confirm your pet's reservation (just to make extra sure).
10. Get to customs and eagerly try to show them your completed health certificate like you
colored something at Sunday school and you want them to hang it on their fridge. Find to your dismay that they don't even freaking look at it. Congratulations, you leaped through a bunch of bureaucratic hurdles and your pet is an international traveler!
Because I went to the UK from the Netherlands I had the tapeworm treatment there and had the vet issue me a Pet Passport which allows the dogs to travel freely throughout the EU and UK. This was very easy, I just showed them the health certificate and they filled out the passport for me with all the relevant details.
Not too long ago it would have been almost impossible to take your dog to the EU because there were quarantines and a drawn out rabies testing process, but now the UK has come into line with the EU animal import regulations and even though the list above looks really daunting, it just takes a little bit of planning. Another note: this list only applies to people coming from the U.S. and Canada and other low rabies incident countries. Good luck!
FYI, this is what the health certificate looks like, on the bottom is the USDA stamp.
These are the E.U. pet passports, although I'm still not clear on the word "gezelschapsdieren."
