Canada to USA Export

Nerthus is pleased to provide the information required to import a puppy into the United States.

Please see the following information below.

All dogs entering the U.S. must be vaccinated against rabies unless they are arriving from a country that is free of rabies. Puppies must not be vaccinated against rabies before 3 months of age. A dog’s first rabies vaccine must be given at least 30 days before arriving in the U.S., so a puppy must be at least 4 months old to be imported into the U.S. from a country where rabies is present.

Anyone who wants to import puppies that are too young to be vaccinated against rabies from countries that are not free of rabies should be aware that the rabies vaccination requirements are very strict. Unvaccinated dogs that arrive in the U.S. from countries that are not considered rabies free may be denied entry to the U.S. and returned to the country of origin at the importer’s expense. Questions about importing unvaccinated dogs may be directed to CDC at

CDC strongly recommends that puppies not be imported until they are fully immunized against rabies.

Pet owners should know that each state and U.S. Territory has its own rules for pet ownership and importation, and these rules may be different than the federal regulations. For example, Hawaii and Guam have especially stringent quarantine regulations. To check the animal import requirements for your destination state, please visit the USDA Animal and Plant Health Inspection Service website at, click on “Imports & Exports,” then click on “Animals,” then click on “Importing into the US,” and find the link on that page for “State requirements and regulations to import an animal or animal product into each U.S. state and territory.” To learn about any fees or policies associated with bringing pets on board, check with your airline. If you have any questions or have any problems at the port of entry, you can contact the nearest CDC Quarantine Station:

Occasionally, young pets do become sick or die during flights into the U.S. It is difficult for very young animals to regulate their temperature on flights and they can become too hot or too cold. If your puppy arrives sick or dead, public health officials are required to find out what happened. It is important to make sure that your pet did not die of a contagious disease that could infect people. This might involve a necropsy or other tests, at your cost, to determine the cause of death. Unfortunately, in many instances the animal’s remains cannot be returned to you after this testing.

It is very important to know that your pet is healthy enough to travel by air. If there is any doubt, consider leaving your pet with a trusted friend, family member, or boarding kennel during your trip, or think about taking another mode of transportation if possible.
