EU pets: Dogs arriving in the United States from abroad must meet the CDC rules in force since August 2024: at least six months old, healthy on arrival, an ISO-compatible microchip implanted before any rabies vaccination, and a CDC Dog Import Form receipt obtained online in the days before travel. There is no EU pet passport route into the US; the EU document is not accepted on its own.
Non-EU pets: Requirements tighten for dogs that have been in a country the CDC classes as high risk for dog rabies in the previous six months: a valid rabies vaccination certificate, and in some cases a rabies serology titre and arrival at an approved port. Colorado itself requires dogs to be vaccinated against rabies, and Denver residents must license their dog; a dog identified as a pit bull type in Denver needs a breed-restricted permit from Denver Animal Protection.
