Is it simpler to travel with pets from Europe into Canada, and not?
As far as I know, the requirements for entering Canada and the U.S. are the same: up-to-date rabies vaccination and an International Health Certificate signed by a veterinarian. There is no quarantine for dogs and cats. I dont know about other animals. I have never heard of any U.S. states having requirements any different than the country overall. Even if they did, how could they enforce them? I dont know the exact details for the UK and Australia, but do know that they are much, much stricter.
