Accompanied vs. Unaccompanied: Why the Rules Change When You Are Not in the Vehicle
Most people planning a cross-border move for their dog research it by age. Age matters, but for a dog under eight months the bigger variable is whether you are in the vehicle. The same puppy, on the same day, needs a different document set depending on that one fact. Here is exactly what changes, what does not, and why the distinction exists at all.

The whole answer, in one table
Entering Canada from the United States:
| Situation | Health certificate | Rabies | Customs entry |
|---|---|---|---|
| Under 8 months, unaccompanied | Required. Examined by a US-licensed vet, presented at the first Canadian port of entry within 72 hours of the exam. | From 3 months | Yes, filed by a broker |
| Under 8 months, with the owner | Not required | From 3 months. Under 3 months, none required | No, you declare it yourself |
| 8 months and older | Not required, either way | Required, and currently vaccinated | Only if unaccompanied on a for-hire carrier |
This page covers privately owned, non-commercial pets. Commercial imports, meaning dogs brought in for resale, adoption, fostering, breeding, show or research, run on a different track with a permit and a scheduled inspection. See commercial vs. non-commercial if you are not sure which side you are on.
Two separate questions, not one
People collapse these into a single question and get lost. They are two. Accompanied or unaccompanied describes who travels with the animal. Personal or commercial describes why the animal is entering Canada. CFIA asks them separately, and the answer to one does not settle the other.
Purpose decides the personal or commercial classification. Accompaniment decides which document pathway applies inside that classification.
| Situation | Accompanied? | Import purpose |
|---|---|---|
| A Canadian family flies to the breeder and brings its own puppy home | Yes | Personal |
| A transporter carries an already purchased puppy to its Canadian family | No | Personal, if the buyer owned it before it crossed and can prove it. See below |
| A Canadian breeder personally collects a dog for a breeding program | Yes | Commercial |
| A breeder, dealer or rescue brings animals in for sale, adoption, fostering or placement | Either | Commercial |
| A dog under 8 months entering temporarily for a recognized show or trial | Either | Special case, with proof of entry required at the border |
Four things follow from reading it as two questions:
- An unaccompanied animal is not automatically commercial.
- An accompanied animal is not automatically personal.
- Hiring a transporter is a transport decision. It does not decide your CFIA classification.
- Buying a puppy from a US breeder does not make it commercial. What matters is that you owned it before it crossed and can prove that on paper. The next section explains how.
The sold puppy question: what CFIA told us in writing
This is the case almost every buyer we speak to is actually in: the puppy is paid for, the Canadian buyer owns it, and it is coming home to be somebody's pet. Is that personal or commercial?
We put exactly that question to CFIA through Ask CFIA in September 2026 and got a written answer on September 24. CFIA defines a personal pet dog as one that is intended to live with the owner, who must also be the importer, and that is not intended for transfer of ownership or fostering once it arrives in Canada, or for breeding, resale, showing or research. The owner must be able to show, if asked, that they owned the dog before it entered Canada.
So the line falls at the border, not at the sale. A puppy you bought and owned before it crossed, coming to live with you, fits CFIA's description of a personal pet. A puppy that changes hands after it arrives does not. If you cannot prove ownership, CFIA may treat the import as commercial, and the commercial requirements apply.
Proof of ownership is where buyers get caught out. CFIA says it has to:
- Describe the dog clearly: age, breed, sex, colour and markings, weight and microchip number.
- Name you as the owner, and show when you became the owner.
- Come from documents such as a purchase agreement, vet records or vaccination certificates from a licensed vet, or a microchip registration.
Photos and signed self-declarations are not accepted. Ask your breeder for a dated bill of sale that carries the microchip number before the puppy travels.
Because you are not travelling with the puppy, CFIA treats it as a personal dog unaccompanied by owner, and those requirements apply, including the health certificate rules in our unaccompanied health certificate guide. Puppies under three months, and hybrid breeds, carry extra requirements. CBSA may have its own requirements when someone carries the dog on your behalf.
Two limits on all of this, also from CFIA. It cannot pre-classify or pre-approve an import: the decision is made by CBSA or CFIA at the first port of entry, on the facts of that crossing. And the importer is responsible for meeting every requirement that applies. If your situation is unusual, call the CFIA animal health office nearest the crossing before you book. New Brunswick animal health is 506-851-7654.
One thing is clear regardless. A bill of sale is not a loophole. Ownership paperwork does not convert breeding stock, resale inventory, rescue placements, research animals or exhibition animals into personal pets. The purpose at the time of import is what counts, and dating a document differently does not change it.
Why the distinction exists
It looks arbitrary until you think about what a border officer is actually being asked to decide. A dog arriving with its owner arrives with a person who can answer for it. Where did it come from, how old is it, is it yours, why is it entering the country. The owner is the assurance.
A puppy arriving in a stranger's vehicle has nobody in that role. The driver did not raise it, did not vaccinate it, and did not see it born. So the assurance has to be written down in advance by somebody qualified to give it, which is why the certificate is a veterinarian certifying, in their own name and under their own licence number, that the puppy was examined, is at least eight weeks old, is vaccinated, is healthy, and is fit to make the trip without undue suffering.
Read that way the rule is not red tape. The certificate is the owner's stand-in. That is also why it has such a short life: seventy-two hours is roughly how long a snapshot of a puppy's health stays trustworthy.
What changes when you are not in the vehicle
A veterinary health certificate, for a puppy under 8 months
Not a generic interstate certificate. There is a specific two-page APHIS form for non-commercial dogs eight months of age and less, with seven numbered clauses, and the examination has to fall within 72 hours of reaching the Canadian border. What every clause requires is set out in what your vet must put on the health certificate.
A formal customs entry
A pet moving on a for-hire carrier is cargo on paper, even though it is a family pet in fact. That means a formal entry, filed by a customs broker. If you drive down and collect the puppy yourself, you declare it at the booth and there is no entry to file and no broker to hire.
Who signs and who books what
On an accompanied trip you do everything. On an unaccompanied trip the work splits: the breeder books the veterinary appointment and holds the puppy until pickup, the transporter supplies the crossing time and the carrier details, and the broker files the entry. Your job from Canada is mostly to be reachable and to have paid.
What does not change
- No minimum entry age. Canada sets none. The six-month wall people worry about is a United States entry rule in the opposite direction.
- No quarantine on arrival in Canada, at any age, either way.
- No CDC Dog Import Form. That is a US entry requirement, not a Canadian one.
- Rabies rules are identical. Required from 3 months, valid within 3 years of entry. A puppy under 3 months is exempt because it cannot yet be effectively vaccinated.
- Your import category. A pet you are keeping is non-commercial in both cases.
The case that catches people
A buyer plans to drive down and collect the puppy in person. Two weeks out, something gives way. Work will not release the time, the weather turns, the border wait looks brutal, or the second driver drops out. So they call us.
Same puppy, same breeder, same date. Different document set. It now needs the veterinary examination inside 72 hours of the crossing and a customs entry, and the breeder needs to know to book that appointment. Nothing about the animal changed. Only the seat it is riding in.
If your plans shift, tell your breeder and your transporter straight away. Three days is enough notice to arrange a vet appointment. Three hours is not.
Flying alone vs. driving alone
CFIA does not distinguish between them. Unaccompanied is unaccompanied, and the certificate requirement is the same whether the puppy is in a transport vehicle or in an aircraft hold.
The practical difference is margin. On the road we can adjust a departure by a few hours to keep the certificate comfortably inside its window. A cargo flight leaves when it leaves, and the crate has to meet IATA specification or the shipment is refused at the warehouse. Air is the tighter plan, so the vet appointment gets booked against the flight rather than the other way around.
Confirm before you travel
Treat this as general information, not legal or veterinary advice. Requirements change and a border officer always has the final say, so we confirm current requirements for every trip.

FAQs
Does my dog need a health certificate to enter Canada?
It depends on age and on whether you are travelling with it. A dog 8 months or older needs no health certificate either way, just a valid rabies certificate. A dog under 8 months travelling with its owner needs only proof of current rabies vaccination, or proof of age if it is under 3 months. A dog under 8 months travelling unaccompanied needs an examined veterinary health certificate, presented at the first Canadian port of entry within 72 hours of the examination.
Why does it matter whether I am in the vehicle?
An accompanied dog arrives with the person who owns it, who can answer for where it came from, how old it is, and why it is entering the country. When the owner is not there, the certificate is what stands in for them. A veterinarian signs to say the puppy was examined, is healthy, is old enough, is vaccinated, and is fit to make the trip, so the document carries the assurance the owner's presence would otherwise carry.
Does unaccompanied mean my import is commercial?
No. Purpose decides that, not who is driving. A puppy you have bought and are bringing home to keep is a non-commercial import whether you collect it yourself or hire a transporter. Commercial covers dogs imported for resale, adoption, fostering, breeding, show or research.
Is flying alone treated differently from driving alone?
Not by CFIA. Unaccompanied is unaccompanied, so the certificate requirement is the same in a transport vehicle or an aircraft hold. What changes is practical: an IATA-compliant crate, a flight time you cannot move, and a tighter margin on the 72-hour window.
I planned to drive down and collect the puppy myself, but now I cannot go. What changes?
The same puppy on the same date now needs a veterinary health certificate examined within 72 hours of the crossing, and a formal customs entry filed by a broker. Nothing about the puppy changed, only who is in the vehicle. This is the most common version of this situation we see, and it is worth telling your breeder and your transporter as soon as your plans change.
Does my dog need a customs broker?
Not by law. CBSA says importers may prepare and submit their own documentation, so you can clear your own dog. What you cannot do is have your transporter do it for you. CBSA Memorandum D17-1-3 says the carrier transporting the goods cannot act as an agent of the importer unless it is a licensed customs broker, and we are not one. So on any move where you are not at the border yourself, a broker files the entry. If you meet the dog at the port of entry, you can clear it yourself. Note that unaccompanied means the dog did not travel with you, not that nobody meets it.
What does not change between the two?
Quite a lot. Canada sets no minimum age to enter, in either case. There is no post-import quarantine, at any age. The CDC Dog Import Form is a United States entry requirement and does not apply coming into Canada in either case. The rabies rules are identical: required from 3 months, on a certificate in English or French that clearly identifies the dog and shows it is currently vaccinated.
My dog is over 8 months and travelling alone. Does it need a certificate?
No. The health certificate requirement applies to dogs eight months of age and less. An adult dog travelling unaccompanied needs a valid rabies certificate, and the shipment still needs its customs entry because it is moving on a for-hire carrier.
