To travel with a pet from Canada to the United States by land or air, your dog or cat needs a rabies vaccination certificate and, for dogs, proof of a microchip. There is no mandatory quarantine for healthy pets arriving from Canada, but you must meet U.S. Centers for Disease Control and Prevention (CDC) requirements, which changed significantly for dogs on August 1, 2024.
Background: Why the Rules Changed
For decades, the U.S. allowed Canadian pets to cross the border with just a rabies certificate. However, in 2024 the CDC introduced stricter rules for all dogs entering the U.S., including those from Canada, to prevent the reintroduction of dog rabies variants that are still present in some countries. The new regulations apply to dogs of any age, including puppies, and to service animals. Cats are not subject to the same new rules, but they still need a current rabies vaccination if they are over three months old.
How It Works: Step-by-Step for Dogs
To bring a dog from Canada to the U.S., follow these steps before you travel:
- Microchip: Your dog must have an ISO-compatible microchip (15-digit). If the chip is not ISO, you must bring your own reader.
- Rabies vaccination: Your dog must be vaccinated against rabies at least 28 days before arrival. The vaccine must be administered after the microchip is implanted.
- Complete the CDC Dog Import Form: Fill out the online form (available on the CDC website) within 10 days of arrival. You will receive a receipt to show at the border.
- Gather documents: Bring the rabies certificate (signed by a licensed veterinarian), the microchip number, and the CDC receipt.
- Choose your port of entry: If you are flying, your airline must be approved by the CDC to carry dogs into the U.S. If driving, you can cross at any land border, but be prepared for a veterinary inspection.
For puppies under 6 months, the rules are slightly different: they must have a microchip and a rabies vaccine (if over 3 months), but they do not need to wait 28 days if they are under 6 months. However, they must be accompanied by an adult and meet all other requirements.
How It Works: Cats and Other Pets
Cats are simpler. You need a rabies vaccination certificate if the cat is over 3 months old. The vaccine must have been given at least 30 days before travel (though some border agents may accept a certificate with a date). No microchip is required for cats, but it is recommended for identification. For other pets like ferrets, rabbits, or birds, the rules vary by species. Ferrets need a rabies certificate, while birds may require a veterinary health certificate and an import permit from the U.S. Fish and Wildlife Service. Always check the USDA APHIS website for species-specific requirements.
Costs and Fees
The cost of pet travel from Canada to the U.S. includes several components:
- Veterinary visit: For a rabies vaccine and certificate, expect to pay $50–$150 CAD.
- Microchip: If your pet doesn’t have one, it costs about $50–$100 CAD.
- CDC Dog Import Form: Free, but you must complete it online.
- Airline fees: If flying, airlines charge $100–$500 USD each way for pets in cabin or cargo.
- Border inspection: There is no fee for the CDC inspection, but if your dog is held at a CDC quarantine facility, you will pay for boarding.
Common Problems and How to Avoid Them
The most frequent issue is missing the 28-day rabies waiting period for dogs. Many travelers show up with a vaccine given 10 days prior, and they are turned away or forced to wait at the border. Another common problem is a microchip that is not ISO-compatible. If your dog’s chip is not 15 digits, you must bring a reader, or the dog may not be allowed entry. Also, the CDC form must be submitted within 10 days of arrival; if you submit it too early, it is invalid. Finally, some airlines do not allow dogs in the cabin on certain routes, so check with your airline before booking.
Comparisons: Land vs. Air Travel
Driving across the border is often easier because you can present your documents directly to a CBP officer. However, land border crossings can have long lines, and if your dog appears sick, you may be referred to a secondary inspection. Flying is faster but more restrictive: you must use a CDC-approved airline, and your dog must meet airline-specific crate requirements. Also, if you fly into a non-approved airport, you will be redirected. For most travelers, driving is simpler and cheaper, but flying is necessary for long distances.
Safety and Health Considerations
Before traveling, ensure your pet is healthy enough for the trip. For air travel, check with your veterinarian about the risks of flying for brachycephalic (flat-faced) breeds like pugs or bulldogs, as many airlines restrict them due to breathing issues. Always carry a first-aid kit and your pet’s medical records. During the trip, never leave your pet alone in a car, and if crossing in summer, avoid midday heat. Also, consider that the U.S. has different diseases (like heartworm) that your pet may be exposed to; ask your vet about preventive medications.

Sample (fictional): For a dog named Max, a 3-year-old Labrador, the owner would check: microchip (Yes), rabies vaccine given 45 days ago (Yes), certificate signed by Dr. Smith (Yes), CDC form submitted on June 1 (Yes), receipt printed (Yes), airline approved (United, Yes), crate size large (Yes), health certificate from Dr. Smith dated May 30 (Yes).
Frequently Asked Questions
Do I need a health certificate for my dog to cross from Canada to the US? For land crossings, a health certificate is not required by the CDC, but some airlines require one for air travel. It’s always a good idea to have one from your vet within 10 days of travel.
Can I bring my puppy under 3 months old? Yes, but the puppy must have a microchip and, if over 3 months, a rabies vaccine. If under 3 months, no vaccine is required, but you must still complete the CDC form and meet other requirements.
What happens if my dog doesn’t have a microchip? You cannot enter the U.S. with a dog without a microchip under the new rules. You must have the microchip implanted and wait 28 days before travel (unless the dog is under 6 months).
Are service dogs exempt from the CDC rules? No, service dogs must also meet the same microchip, rabies, and form requirements. However, they may be allowed to travel in the cabin with their handler.
Can I take my pet on a ferry from Canada to the US? Yes, but the same rules apply. You must have the necessary documents, and the ferry company may have additional requirements, so check with them in advance.
Do cats need a microchip to enter the US? No, cats do not require a microchip, but they need a rabies vaccination certificate. Some airlines may require a microchip for identification, so check with your carrier.
