It is best to contact the embasy of the country yoru going to and those you pass through.
depends on your route.
As far as I know through France they cannot travel under 3 months and must be Rabies vaccinated and a month must elapse since the vaccination.
Other Euro countries do not require Rabies or any other vaccinations under 12 weeks, so this is the option that those who have had pups from me in Holland and Spain took.
They did need Pet Passports, to be identified and vet checked.
