After updates on July 17 and again on July 22, CDC majorly relaxed the rules for dog owners regarding the requirements.  At this moment, the following is the information we received:

1. Dogs must be 6 months or older.

2. Dogs must have a microchip that can be detected with a universal scanner to identify them (i.e. have an ISO microchip).

3. Dogs must be healthy upon arrival.

4. Owners have to apply for the CDC Dog Import Form online.

No forms are needed from veterinarians and no need to go to CFIA for endorsement.

Even though a rabies vaccine certificate was not mentioned in the requirement, we do recommend preparing a certificate of the current/valid rabies vaccine.  This was the basic requirement before the rule change, and the reason for the new rules is to prevent rabies from entering the U.S.  If the border does have concerns about the vaccine/rabies status of your dog, having it on hand could prevent any unforeseen complications.  Also, your dog will need proof of a valid rabies vaccine to re-enter Canada.

We recommend checking the following websites for details and validity of the CDC permit before your departure:
