The short version

Every dog entering or returning to the United States needs a CDC Dog Import Form receipt, must appear healthy, must be at least 6 months old, and must have a microchip a universal scanner can detect. If the dog has been only in dog-rabies-free or low-risk countries for the past 6 months, that receipt is the only document CDC requires, and CDC says the form is free. Canada and Mexico are not on CDC’s high-risk country list. A dog that has been in a high-risk country in those 6 months needs more. A U.S.-vaccinated dog needs a USDA-endorsed Certification of U.S.-issued Rabies Vaccination, completed before the dog left the United States, and may arrive at any port named on the receipt. A foreign-vaccinated dog needs a foreign rabies-and-microchip certificate, a valid rabies titer or a 28-day quarantine, and a reservation at a CDC-registered animal care facility, and may not enter at a land border. An unvaccinated dog that has been in a high-risk country in the past 6 months will not be allowed to enter. USDA APHIS adds rules for foot-and-mouth disease and screwworm, including a screwworm certificate for dogs coming from Mexico. Airlines must see the paperwork before boarding. A dollar amount for the veterinarian, the USDA endorsement, the animal-care facility, or an airline health certificate is not stated on the pages we read.

Rules change. This page copies what CDC, USDA APHIS, and U.S. Customs and Border Protection published. We read those pages on Oct 26, 2026. It is not a clearance decision, and it is not a promise that a particular dog will be admitted. Confirm the rules for your dog on cdc.gov before the trip, including the high-risk country list and CDC’s Dog Importation Navigator. CBP says agency regulations are subject to change and that the note on its pets page is for general awareness.

What every dog needs

CDC’s rules cover a dog arriving for the first time and a dog that lives in the United States and is coming home. The requirement depends on where the dog was vaccinated and which countries it has been in during the 6 months before entry. CDC says it publishes these rules to keep dog rabies from being reintroduced, and it recommends that every dog be vaccinated against rabies.

Four things apply across the paths below. The dog must appear healthy on arrival. The dog must be at least 6 months old at entry or return. The dog must have a microchip that a universal scanner can detect. And the dog must have a CDC Dog Import Form receipt. There is no CDC limit on how many dogs one person may bring, and each dog needs its own receipt.

The form is completed online by the person importing the dog, or by someone acting for that person if a disability makes the form hard to complete. CDC emails a confirmation, then a receipt after the email is confirmed. You can print the receipt or show it on a phone. CDC says the form is free. On February 5, 2026, CDC changed the look of the receipt and said the importation requirements did not change. A receipt from the older system is still accepted if the information is accurate and the receipt is not expired.

If the dog is flying, you must show the receipt to the airline before boarding. You must also be able to show it to U.S. Customs and Border Protection when the dog arrives. The person on the form enters a date of birth and one of these: a passport number and the country that issued it, a driver’s license number and where it was issued, or an air waybill or bill of lading number. A fee charged by CBP for the dog itself is not stated on the CBP pets page.

Dogs that have stayed in low-risk countries

Starting August 1, 2024, CDC says the only required document for a dog that has been only in dog-rabies-free or low-risk countries for the past 6 months is the CDC Dog Import Form. The dog must still appear healthy, be at least 6 months old, and have a microchip a universal scanner can detect. It may enter at any airport, seaport, or land border crossing.

CDC tells you how to know which group a country is in. Only high-risk countries are listed. If a country or political unit is not on that list, it is not considered high risk, and the extra high-risk requirements do not apply. CDC still strongly recommends a rabies vaccination for these dogs. A rabies certificate is not stated as a required CDC entry document for this group.

We read the high-risk list dated April 15, 2026. Canada does not appear on it. Mexico does not appear on it. The list does include other countries in the Americas, including Belize, Brazil, Colombia, Cuba, the Dominican Republic, El Salvador, Guatemala, Haiti, Honduras, and Peru. Use the list itself before you travel. A country can be added after this page was checked.

The low-risk receipt is the shorter one, without a photo. It is valid for multiple entries for 6 months from the day it is issued, unless the dog visits a high-risk country or leaves from a different low-risk country than the one named on the form. CDC’s example is a dog that goes back and forth between the United States and Canada: the same receipt works until the date printed on it. A later trip that departs from France needs a new receipt that lists France. You can complete the form on the day of travel. CDC recommends doing it a few days ahead, or up to six months ahead. Airlines do not scan the microchip for this group, and the microchip number does not appear on the receipt. The dog still has to have one.

U.S.-vaccinated dogs coming back from a high-risk country

If the dog received its rabies vaccine in the United States and has been in a high-risk country in the past 6 months, CDC requires two documents before it returns. One is the CDC Dog Import Form receipt. The other is the Certification of U.S.-issued Rabies Vaccination form. A USDA-accredited veterinarian fills out that certification and submits it to USDA for endorsement before the dog departs the United States. CDC says this is a specific CDC form. It is separate from the rabies certificate a clinic gives you to register a dog with a city or county.

The microchip has to be implanted before the rabies vaccine, or CDC says the vaccine is invalid. The microchip number has to be on every required form. Any brand is acceptable if a universal scanner can read it. If the number does not start with 9, CDC says to ask a veterinarian whether it is readable. If a microchip on a dog from a high-risk country cannot be scanned on arrival, the dog may be denied entry and returned to the country of departure at the importer’s expense.

Timing matters, and it has to happen before the dog leaves. A first rabies vaccine has to be given when the dog is at least 12 weeks (84 days) old, or later if the product is licensed only for older dogs, such as 16 weeks. For a dog that has been in a high-risk country, a vaccine given before 12 weeks is not accepted, whatever the product license says. The dog’s first vaccine must be at least 28 days before it leaves the United States, and the certification form is completed at least 28 days after that vaccine. A booster is valid immediately if vaccine coverage has not lapsed. USDA has to endorse the form before departure. CDC says the form cannot be used for re-entry until that endorsement exists. If the dog has already left without this form, and without the older export-certificate option below, CDC says you follow the foreign-vaccinated requirements instead.

The older option is narrow. CDC will accept a USDA-endorsed export health certificate issued by a USDA-accredited veterinarian no later than July 31, 2025, even if USDA endorsed it after that date. It has to be in USDA’s database, list the dog’s age as at least 6 months, list the microchip number, and list a current U.S. rabies vaccination given after the microchip was inserted. CDC says the vaccine usually lasts 1 or 3 years. Any export health certificate issued after July 31, 2025 is not accepted for CDC’s dog rules.

The certification can be used more than once, for as long as the rabies vaccine is still valid. The CDC Dog Import Form receipt for this path is different from the low-risk receipt. It is valid for a single entry, and only on the arrival date printed on it. If the date, the port, or another answer changes, you submit a new form. The receipt includes a photo of the dog’s face and body. A dog under one year old should have that photo taken within 15 days before travel. CDC says you can show the receipt and the endorsed certification to the airline, a cruise ship, and Customs and Border Protection. The dog may arrive at any airport, land border, or seaport, as long as that place matches the receipt.

What the veterinarian charges, and what USDA charges to endorse the form, is not stated as a dollar amount on the CDC page. CDC says those costs are set by the veterinarian and by USDA, and it points veterinarians to USDA’s cost list. If the clinic has no USDA-accredited veterinarian, CDC describes two options and says the veterinarian might require a new rabies vaccine before issuing the form. CDC itself does not require that revaccination.

Foreign-vaccinated dogs from a high-risk country

A dog vaccinated outside the United States, after time in a high-risk country during the past 6 months, has a longer list. CDC requires a Certification of Foreign Rabies Vaccination and Microchip form, a valid rabies serology titer from a CDC-approved laboratory or a 28-day quarantine, a reservation at a CDC-registered animal care facility, an itinerary that flies the dog into the airport where that facility is, a microchip implanted before the vaccine, a healthy appearance, an age of at least 6 months, documents in English or with a certified English translation, and the CDC Dog Import Form receipt.

A veterinarian completes the foreign certificate. An official government veterinarian in the exporting country endorses it. The form has to be completed no more than 30 days before travel, and it can be used once. It is valid for 30 days after the examining veterinarian signs it. For a first vaccine, the dog must be at least 12 weeks old when it is vaccinated, and that vaccine must be given at least 28 days before the dog enters the United States. The same 12-week floor applies: a vaccine given earlier is not accepted for a dog with a high-risk history.

A valid titer is a passing blood test showing the dog is immune to rabies after vaccination. A veterinarian draws the sample at least 30 days after the first valid vaccine and at least 28 days before entry. If the dog has a history of more than one valid vaccine after the microchip, with no lapse, the sample can be drawn any time after a booster, as long as the first vaccine was at least 30 days before the sample. CDC accepts results only from laboratories on its approved list. A passing result lasts for the life of the dog if vaccination coverage does not lapse and the laboratory stays approved. Carry the laboratory report. If there is no valid titer, the dog can be admitted after 28 days of quarantine at the animal care facility. The FAQ describes a way that quarantine can be shortened for a personal pet or service dog. Rescue, resale, adoption, and transfer-of-ownership dogs are not eligible for that shorter quarantine. The dollar cost of the test is not stated.

The reservation is made by the importer or owner, with the facility at the arrival airport. The facility reviews the papers before it issues the reservation. At the facility every foreign-vaccinated dog from a high-risk country is examined and revaccinated with a U.S.-licensed rabies vaccine. A dog without a valid titer is also quarantined for 28 days. If the veterinarian finds the dog sick, CDC may require more tests or treatment, and a dog that arrives sick may be denied entry. All of those costs are the importer’s. CDC says to ask the facility what they will be. A single published price is not stated. The reservation confirmation has to travel with the dog and be shown to the airline before boarding and to Customs and Border Protection on arrival.

The flight has to land at that airport, and that airport has to be the one on the CDC receipt. CDC says there are currently no registered animal care facilities in Alaska, Hawaii, or U.S. territories, so these dogs may not enter through those places. Domestic flights and other travel onward inside the United States wait until the facility services are done and CDC has authorized release. CDC does not allow this dog to enter at a land border crossing. The list of facilities is on CDC’s site. Which airports are on it today is not copied here, because that list is the record.

CDC defines a certified translation as a signed statement on professional letterhead from a licensed translator, saying the translation is accurate, with the translator’s name, address, contact information, and a stamp or seal that includes the license number. A footnote on the same page says dogs are inspected at the port and may be denied entry if they have evidence of a zoonotic disease. An ill or injured dog might need more examination, testing, and treatment by a licensed veterinarian, at the owner’s expense, before entry.

Driving in from Canada or Mexico

CDC answers the frequent-traveler question directly. If the dog has not been outside Canada, Mexico, and the United States, you fill out the CDC Dog Import Form online and that is the only form CDC requires. The receipt works for multiple entries for six months, as long as the country of departure stays the same. A dog that usually crosses from Canada, and then later departs from Mexico, needs a new receipt that lists Mexico. The same is true in the other direction.

A low-risk dog can use any land border crossing, and any airport or seaport. The requirements do not loosen because the dog stays in the car. CDC says a dog entering at a land border must meet the entry rules even if it will be in the vehicle most of the time and will not spend the night in the United States.

The land border closes for one group. A foreign-vaccinated dog that has been in a high-risk country in the past 6 months is not allowed to enter at a land border, including a crossing from Canada or Mexico. That dog has to fly to an airport with a CDC-registered animal care facility where it has a reservation. A U.S.-vaccinated dog with the endorsed certification and a receipt that names that land crossing may use the land border.

USDA is a separate question from CDC’s rabies forms. APHIS says it has requirements only if the dog is coming from a country affected by foot-and-mouth disease or screwworm. On the pet-dog page, APHIS says the screwworm freedom certificate required for dogs traveling from Mexico may be issued by a clinical veterinarian in Mexico who is trained and authorized to sign for the official government veterinarian. The inspection has to be within 5 days before shipment. The certificate says the dog is free of screwworm, or that it was infested, quarantined, and treated until free. APHIS does not publish a required template. The paper can stand alone or sit inside an export health certificate. The dog is inspected at the port of entry. Whether Canada is on the screwworm list or the foot-and-mouth list is not stated on that pet-dog page.

Where USDA APHIS also matters

APHIS says CDC is the primary authority for dogs imported into the United States, including dogs that started in the United States and are returning. CDC and APHIS Veterinary Services regulate different parts of the same trip, and both sets of requirements have to be met. For the U.S.-vaccinated high-risk path, APHIS is also the agency that endorses the Certification of U.S.-issued Rabies Vaccination before the dog leaves. The veterinarian submits it through USDA’s Veterinary Export Health Certification System. APHIS says that form cannot be issued after the dog has already left.

APHIS Veterinary Services adds its own health rules only when the country is affected by foot-and-mouth disease or screwworm. For foot-and-mouth disease, the dog’s fur and bedding must be free of excessive dirt, hay, or straw. The dog should be bathed as soon as it reaches its destination and kept separate from all livestock for 5 days after entering the United States. APHIS says no document is required for those steps. For screwworm, entry is allowed only with the certificate described in the Canada and Mexico section. APHIS says documentation is reviewed and the dog is inspected at the port of entry.

A family pet and a dog imported to be sold or adopted are not the same file. APHIS says the Animal Welfare Act does not apply to a privately owned dog that is not intended for resale. Dogs imported for resale, including retail or wholesale sale or adoption for a fee or donation, need an Animal Care import permit, and the importer has to meet the health certifications and other criteria on the commercial-import page. Those dogs are also at least 6 months (180 days) old at entry. CDC’s rules and the Veterinary Services rules still apply on top of the permit. CBP describes the same split: Animal Care has extra requirements for dogs imported for resale or adoption for a fee or donation.

APHIS says the importer is responsible for the destination U.S. state’s or territory’s requirements, and it points people to that state’s agriculture department. What any one state requires is not stated on the CDC, APHIS, or CBP pages we read. APHIS also has a separate sentence for livestock-handling dogs imported from most of the world: they should have no evidence of tapeworm infection, with an exception for dogs from Canada, Mexico, and certain regions of Central America and the West Indies. A tapeworm rule for an ordinary pet is not stated.

Where the airline and the border officer fit

CDC’s page for air carriers says airlines must confirm the documents before a dog boards a flight to the United States, including a dog that is coming home and including a service dog. For every dog, the airline confirms that the dog appears healthy, appears to be at least 6 months old, has a microchip, and has a CDC Dog Import Form receipt. If the importer does not have the receipt at the gate, CDC says they can complete the form on a phone before boarding. There is no charge to the importer for submitting it.

For a high-risk history, the airline also checks that the receipt matches the other papers, that the dog is entering on the arrival date on the receipt, and that the aircraft is landing at the airport named on the receipt. The other paper is a Certification of U.S.-issued Rabies Vaccination, a USDA-endorsed export health certificate issued no later than July 31, 2025, or, for a foreign-vaccinated dog, proof of the animal-care-facility reservation at that airport. If a foreign-vaccinated dog is headed to a different airport, or has no reservation, CDC says the airline should deny boarding. The airline should also deny boarding if the dog appears ill or appears to be less than 6 months old, or if any required document is missing. CDC tells the airline to send the traveler to CDC’s dog-import site to get the papers. Airlines do not have to call CDC for permission before boarding a dog that has the documents.

Air carriers must also create an air waybill for each dog, including a dog in the cabin or in checked baggage, unless CDC has granted that carrier a waiver. CDC says Customs and Border Protection may still require an air waybill even when CDC has waived it. Whether your airline has a waiver is not stated on the traveler pages we read.

CBP works with CDC and USDA at the port. CBP says every pet must meet all applicable requirements before travel. A dog or cat that looks sick may need a licensed veterinarian’s examination at the owner’s expense. A pet that is excluded is returned to the country where the trip started, at the owner’s expense, and it can be held at the port at the owner’s expense while that is arranged. CBP’s summary says CDC requires valid proof of rabies vaccination for dogs arriving from high-risk countries, and it sends readers to CDC’s dog page for the details. CBP recommends contacting the port before you arrive. It also says its CBP Link app can be used for pet importation at select ports. Which ports, and whether an appointment is required for your crossing, are not stated as a national rule on that page.

CBP says to check with the airline before travel because the airline can add its own requirements. CBP says airlines generally require health certificates for traveling pets and may charge fees or set rules about which pets can come aboard. A dollar fee, a required certificate form, and a carrier size are not stated on the CDC or CBP pages. Those live on the airline’s own pet page. The cabin fee, when the airline publishes one, is a different question from the import papers.

The cabin fee is the airline’s own number, copied on what US airlines charge to bring a dog in the cabin. A service dog’s hotel bill is a different statute from this import rule. Can a hotel charge a pet fee for a service dog? If the drive continues after the crossing, rental-car pet rules are the company’s policy, not CDC’s.

Your questions, answered

AgeHow old does a dog have to be to enter the United States?

At least 6 months old at the time of entry or return. CDC states that age for dogs from low-risk countries and for dogs from high-risk countries. CDC tells airlines to deny boarding if a dog appears to be less than 6 months old. APHIS repeats CDC’s 6-month minimum for a pet dog, and APHIS Animal Care also requires at least 6 months, which it writes as 180 days, for a dog imported for resale or adoption. An exception that lets a younger puppy enter is not stated.

The formDoes every dog need a CDC Dog Import Form receipt?

Yes. CDC says every dog entering or returning to the United States must have a CDC Dog Import Form receipt, and each dog needs its own. There is no limit on the number of dogs if every dog meets the entry rules. CDC says the form is free. You show it to the airline before boarding if the dog is flying, and you show it to U.S. Customs and Border Protection on arrival. On February 5, 2026, CDC updated the look of the receipt and said the requirements did not change. An older receipt is still accepted if the information is accurate and it has not expired.

Low-risk countriesWhat if my dog has only been in Canada, Mexico, or another low-risk country?

If the dog has been only in dog-rabies-free or low-risk countries for the past 6 months, the CDC Dog Import Form receipt is the only document CDC requires. The dog must still appear healthy, be at least 6 months old, and have a microchip a universal scanner can detect. It may enter at any airport, seaport, or land border. Canada and Mexico do not appear on the high-risk list dated April 15, 2026. CDC recommends a rabies vaccination and says the extra high-risk requirements do not apply. A rabies certificate is not stated as a CDC entry document for this group. The receipt can be reused for 6 months from the same country of departure.

Land borderCan I drive a dog into the United States from Canada or Mexico?

Yes, if the dog has not been in a high-risk country in the past 6 months and it has the CDC Dog Import Form receipt, is at least 6 months old, appears healthy, and has a readable microchip. The same receipt covers repeat crossings for six months while the country of departure stays the same. Switching the departure country, from Canada to Mexico or from Mexico to Canada, means a new receipt. CDC applies the same rules if the dog is only riding through and will not stay overnight. A foreign-vaccinated dog that has been in a high-risk country in the past 6 months is not allowed to enter at a land border. A U.S.-vaccinated dog with the endorsed certification may use a land border if that crossing is the one named on the receipt. Dogs coming from Mexico also have an APHIS screwworm certificate, described on APHIS’s pet-dog page. Whether Canada is on the screwworm or foot-and-mouth list is not stated on that page.

Coming homeWhat does a U.S.-vaccinated dog need to come home from a high-risk country?

Two documents: the CDC Dog Import Form receipt, and a Certification of U.S.-issued Rabies Vaccination form. A USDA-accredited veterinarian completes the certification, and USDA endorses it before the dog leaves the United States. CDC says it is a specific CDC form, separate from a local rabies certificate. The microchip has to be implanted before the vaccine. A first vaccine is given at least 28 days before departure, and the form is completed at least 28 days after that vaccine. A booster is valid immediately if coverage has not lapsed. If the dog already left without this form, and without a USDA-endorsed export health certificate issued no later than July 31, 2025, CDC says you follow the foreign-vaccinated requirements instead. The receipt for this path is one entry on the date it lists. The dog may use any port that matches the receipt, including a land border.

Vaccinated abroadWhat does a dog vaccinated abroad need if it was in a high-risk country?

The CDC Dog Import Form receipt, a Certification of Foreign Rabies Vaccination and Microchip form endorsed by an official government veterinarian and completed no more than 30 days before travel, a valid rabies serology titer from a CDC-approved laboratory or a reservation that includes 28 days of quarantine, and a reservation at a CDC-registered animal care facility. The dog must fly into the airport where that facility is located. It is examined and revaccinated there. It may not enter at a land border, and the FAQ says it may not enter through Alaska, Hawaii, or a U.S. territory because those places have no registered facility. Facility costs are the importer’s. The dollar amount is not stated. An unvaccinated dog that has been in a high-risk country in the past 6 months will not be allowed to enter.

The airlineWhat does the airline check before the dog boards?

CDC tells airlines to confirm, before boarding, that the dog appears healthy, appears at least 6 months old, has a microchip, and has a CDC Dog Import Form receipt. For a high-risk history, the airline also confirms the government document or the animal-care-facility reservation, the arrival date, and that the flight lands at the airport on the receipt. If a document is missing, or the dog looks ill or under 6 months old, CDC says the airline should deny boarding. You must show the receipt to the airline before boarding and be able to show it to Customs and Border Protection on arrival. A cabin pet fee, a required health-certificate price, and a carrier size are not stated on the CDC or CBP pages. CBP says airlines generally require health certificates and may charge fees. Published cabin pet fees are on the TravelSuited flying guide at /dog-friendly/us/flying-with-a-dog/.

USDADoes USDA have rules on top of CDC?

Yes, for some trips. APHIS says CDC is the primary authority for rabies, including for a U.S. dog that is returning, and that APHIS Veterinary Services has requirements only when the dog comes from a foot-and-mouth-disease or screwworm country. Foot-and-mouth rules are about clean fur and bedding, a bath at the destination, and 5 days away from livestock, with no document required. Screwworm requires a certificate of inspection within 5 days before shipment. Dogs from Mexico need that screwworm certificate, and a trained, authorized clinical veterinarian in Mexico may sign it. A privately owned dog that is not for resale is not covered by the Animal Welfare Act import permit. A dog imported for sale or for adoption for a fee or donation needs an Animal Care permit as well as the CDC rules. State requirements are the importer’s responsibility. What a state requires is not stated on these federal pages.

Service dogsDo service dogs skip the import rules?

No. CDC says service dogs meet the same requirements as other dogs. CDC uses the definition of a service animal in 14 CFR 382.3. Emotional support animals, comfort animals, companionship animals, and service animals in training are not service animals under that definition. A foreign-vaccinated service dog from a high-risk country still needs an animal-care-facility reservation if it arrives by air, and it still may not enter at a land border. If it arrives by sea with the person it is trained to assist, and it has a valid titer and the other documents, CDC says no facility reservation is required. What a hotel may charge a service dog is a different rule, on the TravelSuited service-dog guide at /dog-friendly/us/service-dogs-and-emotional-support-animals-at-hotels/.

If something is missingWhat happens if the dog does not meet the rules?

CDC says you must follow its dog importation requirements or the dog will not be allowed to enter. Airlines are told to deny boarding when the documents are missing or the dog appears ill or under 6 months old. For a high-risk dog whose microchip cannot be scanned, CDC says the dog may be denied entry and returned at the importer’s expense. CBP says a pet excluded from entry is returned to the country of embarkation at the owner’s expense, and it may be held at the port at the owner’s expense while that happens. A sick dog or cat may need a veterinarian’s examination at the owner’s expense. A dollar amount for that examination, the return trip, or the port hold is not stated.
