Cripes, I had to do all that and more when I brought Alfie over from Spain. From the moment his passport was stamped I had 48 hours to get back to England from Valencia, including an overnight stay in Toulouse. When his leishmaniasis became apparent and his health declined I had to speak to his old vet in Xativa to get drugs that I couldn't get in this country, obtain a veterinary import licence to bring the drugs into this country and pay for my friend to fly back to England with the medicine in his suitcase.
An animal health certificate and a vaccination are a piece of cake by comparison. I'm sure when you've thought this through, you'll decide your dogs are worth the effort.
