Thanks so much all. All the links were very helpful!! Caleb and Meloncollie I did find your information very useful and panicked because they said the dog must have a rabies vaccines 30 days before US entry. I looked at our dog's tag and it expired a few months ago.

When living in the US, our vet would aways remind us of vaccines that were upcoming. I read a little further to find that rabies vaccine is not necessary for entry if you have lived in a rabies free country for more than 6 months. Switzerland is one of those rabies free countries, so I felt much relief.
