Traveling With Dogs From Canada to the US: 2026 Border Requirements

Driving from Canada into the United States with your dog is no longer a matter of assuming a rabies certificate will be enough. U.S. Centers for Disease Control and Prevention rules apply even to dogs returning to the United States, and the documents needed depend on where the dog has been during the previous six months.

This guide reflects official CDC information reviewed in October 2026 and describes the straightforward route for dogs that have spent the previous six months only in dog rabies free or low risk countries. If your dog has visited a high risk country, is being imported commercially, or has an unusual travel history, do not use the simplified checklist in place of the CDC's individualized instructions.

At a glance: the standard low risk pathway

Under the CDC rules applicable to dogs arriving only from low risk or dog rabies free countries, each dog must be at least six months old, have a microchip detectable by a universal scanner, appear healthy at arrival and be accompanied by a CDC Dog Import Form receipt. A separate form is required for each dog.

Canada is treated within the low risk pathway when the dog has not been in a high risk country in the preceding six months. Eligibility depends on the dog's actual movements, not simply your home address or where the trip begins.

• Dog is at least six months old on the day it enters the United States.
• Dog has an acceptable microchip and appears healthy.
• One CDC Dog Import Form receipt for each individual dog.
• Any extra requirements triggered by travel to a high risk country have been resolved in advance.

What changed in 2026?

CDC updated the online Dog Import Form system on February 5, 2026. According to CDC's April 28, 2026 instructions, that change affected the form's look and receipt formatting, not the underlying entry requirements. Existing valid receipts from the previous system remain acceptable when the information is accurate and the receipt has not expired.

Do not assume that a social media post describing rules from before August 2024 still reflects present requirements. Use the CDC's live Dog Importation Navigator and the official form instructions on each trip.

CDC Dog Import Form: when and how to complete it

The importing person completes the form online and confirms the email address to receive a receipt. For eligible dogs from low risk or dog rabies free countries, CDC says the receipt is generally valid for six months from issuance for repeated entries from the same departure country, provided the dog's circumstances stay within that pathway.

You can present the receipt digitally or in print. Save an offline copy in case mobile service is unreliable near the border. A new form may be necessary if the country of departure changes, the receipt expires or the dog's six month travel history changes.

• Use the official CDC website rather than a third party fee site.
• Check dog's identification and microchip information for accuracy.
• Keep a separate receipt for each dog and confirm the expiration date.
• For air travel, be ready to show the receipt to the airline.

Puppies under six months: do not assume an exception

Under the standard CDC dog import rules, dogs younger than six months cannot enter the United States. This can affect Canadian families collecting a puppy, breeders travelling to shows or anyone arranging a vacation with a young dog.

The CDC's guidance and any narrowly applicable exceptions must be checked directly with the relevant agency; an airline or border crossing cannot casually waive the age requirement. Do not plan to cross with a young puppy on the assumption that an ordinary veterinarian letter will be enough.

What if your dog visited a high risk country?

A dog that has been in any CDC-designated high risk country within the six months before U.S. entry does not qualify for the simple low risk checklist even if the dog is travelling from Canada now. Additional forms, rabies documentation, arrival restrictions and possibly a CDC-registered animal care facility may apply.

CDC distinguishes between dogs with U.S.-issued rabies vaccination and foreign-issued vaccination. Use the import navigator and coordinate with the veterinary and government authorities before making nonrefundable arrangements.

Driving, flying and arriving at the border

For eligible low risk pathway dogs, CDC permits entry through land crossings, seaports and airports. Have the receipt accessible to border officials and do not let travel documents become buried in luggage. At airline check in, pet bookings and carrier policies are a separate issue from CDC entry permission.

Declare the dog when asked and cooperate with inspection. A receipt does not guarantee admission if your dog appears unwell or does not meet the rules. Check entry rules for your U.S. state, destination accommodation and any carrier you will use.

Returning from the United States to Canada

Entering the U.S. and returning to Canada are separate legal steps. Canada's CBSA and CFIA administer Canadian entry requirements. Identify whether your dog is a personal pet returning with its owner or falls into another classification, and check the CFIA import requirements for its age, origin and purpose.

Keep proof of ownership, identification and appropriate vaccination records ready. CBSA states that pets must be declared and that missing documents, illness or inappropriate transportation can result in enforcement or refusal. Commercial dogs and dogs transferred to another person may follow different rules from personal dogs.

A practical week before departure checklist

Do a document review before leaving rather than on the morning of your crossing. Where you need veterinary appointments or certificates, allow additional time for official endorsement or correction.

For the drive itself, pack regular food and water, a secure restraint, an identification tag and a rest stop plan. Border waiting times can change, so do not leave your dog without access to necessary care.

• Check the latest CDC low risk country and import pages.
• Confirm age and scan microchip at a veterinary clinic if uncertain.
• Submit a separate CDC Dog Import Form for each dog.
• Check CFIA and CBSA conditions for re-entry into Canada.
• Save digital and printed receipts and ownership/veterinary records.
• Review local lodging, park and state-level dog requirements.

Important differences for commercial or transferred dogs

Selling, delivering, adopting or transferring a dog can change the dog's import classification. A dog accompanying its owner on vacation and a puppy being taken to a new home should not automatically be treated as equivalent. The CDC, USDA and CFIA have distinct areas of authority.

If your trip involves breeding, resale, adoption, rescue transport or transfer of ownership, consult the applicable government requirements and your carrier before deciding what documentation is sufficient.

Frequently asked questions

Do Canadian dogs still need a CDC Dog Import Form in 2026?

Yes. Each dog entering or returning to the United States needs the applicable CDC Dog Import Form receipt. More documents may apply based on the dog's preceding six month travel history.

Can I drive a five month old puppy into the United States?

The standard CDC rules require dogs to be at least six months old. Check directly with CDC if you believe a narrow exception applies; do not assume permission.

Does my rabies certificate replace the CDC form?

No. For eligible dogs only in low risk countries, CDC identifies the Dog Import Form as the required documentation, while the dog's microchip, age and health requirements still apply. Other authorities and destinations may ask for additional records.

Can I use one CDC form for two dogs?

No. CDC requires a separate form for each dog.

Will my CDC form be enough to return to Canada?

Not necessarily. Canadian import requirements are separate. Check the relevant CFIA and CBSA guidance before returning.
