New CDC Regulations regarding Dogs. Effective August 1, 2024 .

Please note that the information may not be 100% accurate. As I get more information, I amend this page, the popup at the top tells you when it was amended.

My Opinion: I suspect this will prove unworkable after August 1st, and the rules will be modified or softened by Fall. It is going to have a large impact on US border businesses as short term visits start to dry up. Tese rules have not been well thought out, nor have their impact been properly considered. That should put the pressure on. Information seems to be changing, and I suspect the rules are adjusting due to the uproar over this from some pretty powerful organizatuions, inlcuding US Border Services and the USDA. Already, I am seeing some paragraphs hinting that they may approve rabies vaccines from certified Canadian vets, but as of June 6th this is still rather confusing and contradictory. If you take the preventative actions outlined below, it is your choice. From our own business point of view, we will deal with this when we see how it resolves out, once the dust settles. We are hoping that is prior to Aug 1st. One of our customers has already decided to go into the US ahead of Aug 1st and have her dog re-vaccinated. If doing that is convenient, it is probably still prudent, but I am hoping it will prove not to be necessary. Canadians still have the option to go through a hassle after Aug 1st to get their dog into the US, then do the vaccination there before entering Mexico. It is easier for Americans whose dogs are already in the US.

So, here is what I know so far:

There is considerable panic regarding the new Dog (not applicable to Cats) regulations being implemented as of August 1, 2024. let me assure our customers that we are on this and will have all the details prior to Spring trips.

We have been researching this impact of this on our customers, especially in regard potential problems. I emphasize Potential. We are reasonably confident we now know what you have to do.

Here is what we do know:

1) The pet has to be over 6 months old, so you will be unable to bring puppies younger than that.

2) The dog has to appear in good health. You may obtain a certificate of health from your vet.

3) The dog has to have a currently valid Rabies certificate, and it has to be from a country with low risk of rabies which includes both Canada and Mexico. The animal has to have not been in a high risk country during the last 6 months.

4) The dog has to by micro chipped with an ISO certified chip. These have been standard in the US and Canada for almost 10 years. An older dog may have to be re-chipped. Consult your vet. Note an ISO approved chip has 15 digits, non ISO chip usually has 9. Note: the chip has to be implanted BEFORE the rabies vaccine.

5) A dog cannot enter the US within 28 days of its initial rabies shot.

6) Americans planning to go into mexico need to ensure their dogs rabies shot was administered by a USDA vet. If not they should have the dog re-vaccinated.

7) Cats are not issue as long as they appear healthy

Now the impact is different for Canadians and Americans or if you are currently in Mexico.

If you plan to go into Mexico with your dog, or if you are already there, or if you are Canadian and want to enter the US multiple times with less hassles, read on. It is important.


Americans need to follow the rules above and should have a rabies vaccine administered by a USDA certified vet if they plan to take their dog outside of the US.. You can get a list of USDA certified vets at THIS LINK . From what I can tell, this is all Americans have to do. Follow these instructions.. They should be careful the rabies vaccine does not expire while they are out of country. According to vets I have spoken to, re-vaccinating is safe. It is obviously more desirable the closer it is to the current vaccine expiry. Ensure your dog is chipped with an ISO compliant chip.


If you are able to enter the US before August 1, 2024, I advise you do so, and have your dog re-vaccinated by a USDA vet (if you and the vet consider that safe). Ensure your dog is chipped with an ISO compliant chip. Unless the current vaccine is near expiry, I may be more hesitant, but it is apparently OK. After August 1st, from what I can tell, you will require THIS FORM to be filled out by your vet before crossing into the US. You will have to take it to a CFIA vet who is government certified. Each province has several, but not a lot. You can find locations of their offices at THIS LINK. You will have to pay $20-$25 and it may take a few days. You will have to do this every time you take your dog across into the US unless it has been re-vaccinated by a USDA certified vet, Do not cross into Mexico with the dog unless you have done this. Finding a certified official in Mexico could be a challenge. If you cannot do this, hopefully you can do it in transit southbound to Mexico, but there will be some more paperwork involved.

What you do need to do is ensure

1) The dog will be over 6 months old

2) Get a certificate of health form from your vet (Not necessary but advised)

3) Have your vet confirm your chip is ISO compliant, which it should be if it was implanted prior to 2015, and have the dog re-chipped if necessary and record its ID number. Vets have chip readers, you can also buy one for about $50 on Amazon. If necessary we will equip our Wagon Masters with them so they may be read in Mexico.

4) Before crossing into Mexico, have your dog re vaccinated in the US by a USDA certified vet. List is linked above. You will be good for as long as the vaccine is valid, usually 3 years. Do not take your dog into Mexico unless it has the USDA vaccination. If it does not, you will have to find a Mexican government vet, almost impossible from what I can determine.


Avoid taking your dog to a high risk country. A list of those countries may be found here .


Canadians & Americans already in Mexico

If your dog has been vaccinated in the US by a USDA vet and has an approved ISO chip and you have proof, no problem.. Note an ISO approved chip has 15 digits, non ISO chip usually has 9.

If you plan to bring your dog into the US and it does not have the above, it is almost imperative you take your dog into the US before August 1, 2024. You then need to have it vaccinated by a USDA vet and have the approved chip. If you do not do this, it is likely you will not be able to bring your dog into the US, no matter what your citizenship or the origin of the dog.. The only way around this is to take it to a Mexican government vet, which are hard to find and almost impossible to have them do what it is required.

The CDC criteria for a licensed government veterinarian are that they: 1) Have a government email address (a personal or business/private practice one will be rejected), and 2) Have a government stamp/seal (required after signature for the document to be valid). Because the CDC wants this whole process to occur digitally, government licensed veterinarians are also supposed to use an electronic digital signature program such as DocuSign (creating yet another barrier). A wet signature will be accepted but at the time of writing, we have yet to receive response from CDC special Animal Imports department if a wet signed document scan and upload will be accepted, or if the original will need to be brought in by the person traveling with the dog. Mind you, all of this needs to happen in this 30 day window, and if not, the original exam will need to happen anew to reset the clock. Info Source

ISO Chips :

If your dog is chipped, consult your vet for the information. If you registered it, you should be able to print out a certificate (eg There are only 2 or 3 brands.

Here are 2 communications I have received:

From the CDC:

Dear Paul

The 60-day timeframe is a recommendation for when to start preparing the paperwork. There is no 60-day waiting requirement. Dogs must receive their initial rabies vaccination at least 28 days before entering or returning to the United States, and there is no wait time after a rabies booster vaccine. Canadian and Mexican citizens can have a USDA-accredited veterinarian in the US vaccinate their dog and complete the Certification of US-issued Rabies Vaccination form so they can travel multiple times across the border with the Certification of US-issued rabies vaccination form, which is valid for the length of time the rabies vaccine is valid.
CDC does not have rabies vaccination requirements nor documentation requirements for cats. CDC requires cats to appear healthy on arrival.

From the CFIA:

Dear Paul,

Thank you for your inquiry.  CFIA officials are still in discussion with the USA regarding clarification on these changes.  Unfortunately, we can not provide further information other than what is present on the CDC website at this time.  When additional information specific to dogs originating from Canada becomes available, it will be posted on the CFIA website.  Hopefully soon! 

Thank you for your patience.
