In case you're asked, make sure you have the vaccination certificate signed by the vet, including a description of your pet... you know, color, age, breed. The only vaccination they're interested in at the border is rabies... but if you might use a kennel anywhere on your trip, they will want to see that all the vaccinations are up to date, including bordetella.
Oh, and I'm not sure if the dog food ban has been lifted! Anything with meat was taboo, including doggie kibble. Anybody know about this?
