There is a 'Pet Passport' scheme in place, useful for "sporting" animals (show jumping horses, international cat and dog shows contestants, animal extras for films) which lists every shot the animal has had, what vaccinations are current, what diseases the dog has had and its identity chip details. It's particularly useful for guide animals (Seeing Eye or Hearing Dogs for the deaf) and has proved extremely successful. We still don't have any reported cases of rabies in dogs and there is no appreciable increase in other nasty diseases so it works.

Good luck!
