✈️🐕 Bringing a Dog into the USA in 2026: CDC Dog Import Form, Microchip, Rabies Rules — Complete Guide
Entering the United States with a dog in 2026 is no longer just a matter of a health certificate. CDC rules that took effect in 2024 are now fully enforced. Whether your dog was vaccinated in the US or abroad, whether you're travelling from a low-risk country like Germany or a high-risk country like India, Mexico, or Brazil — the requirements are different, the paperwork is specific, and arriving at the wrong airport means your dog cannot enter at all. Read this guide at least 60–90 days before your flight.
📌 What's in this guide: How the CDC classifies countries as high-risk or low-risk; the 5 February 2026 form system update; the 3 main scenarios (US-vaccinated dog / foreign-vaccinated + titer test / foreign-vaccinated without titer test); how to complete the CDC Dog Import Form; the two Certification forms and their differences; the rabies titer test process; the 6 approved ACF airports and reservations; common mistakes and FAQ.
📋 Quick Answer: What Do All Dogs Need in 2026?
✈️ Universal Requirements — Every Dog Entering the US
Regardless of country of origin, every dog entering the United States must be at least 6 months old, have an ISO-compliant microchip, and a completed CDC Dog Import Form. The dog must also appear healthy at inspection. Beyond these universal requirements, the rules diverge sharply based on one question: Is your dog's country of residence in the past 6 months on the CDC high-risk list? If yes — the requirements are significantly more demanding, entry is limited to 6 airports, and quarantine is possible. If no — the process is considerably simpler. Check the current CDC list at cdc.gov before planning travel.
🚨 5 February 2026 Update: CDC updated the Dog Import Form web system on 5 February 2026. The form's interface and format changed; the entry requirements themselves did not change. Valid receipts issued under the old form continue to be accepted until they expire. Additionally, as of 31 July 2025, the transition period ended: USDA-endorsed export health certificates issued after that date are no longer accepted for returning dogs.
🌍 High-Risk vs. Low-Risk Countries: What Does It Mean?
The CDC evaluates dog rabies risk country by country, based on rabies surveillance quality, dog vaccination coverage, reporting infrastructure, and case history over the past 5 years. A dog that has been present in a high-risk country in the past 6 months — even briefly — is subject to the high-risk pathway. Countries currently classified as high-risk include most of Africa, South and Southeast Asia, the Middle East, Central and South America, and parts of Eastern Europe. The EU, UK, Australia, Canada, Japan, and most of Western Europe are low-risk. Always verify your specific country's status at cdc.gov before travelling, as the list is updated periodically.
🔍 Practical Consequences of High-Risk Status
A dog that has been in a high-risk country in the past 6 months faces two critical consequences at US entry: (1) Entry is only permitted through one of 6 CDC-approved Animal Care Facility (ACF) airports. Arriving at any other airport means the dog will be refused and returned at the owner's expense. (2) At the ACF, the dog will undergo examination and rabies vaccination update — and, if no valid titer test is on file, a mandatory 28-day quarantine. A valid titer test completed at least 28 days before entry eliminates the quarantine requirement.
👥 3 Main Scenarios: Which One Applies to You?
🟢 Scenario A — US-Vaccinated Dog Returning from a High-Risk Country
Your dog was vaccinated in the US, you took it to a high-risk country, and now you're returning.
- Before leaving the high-risk country: A USDA-accredited veterinarian must complete the Certification of U.S.-Issued Rabies Vaccination form via the USDA VEHCS system, and USDA must endorse it digitally. This must be done before the dog leaves the US — retroactive completion is not possible after 31 July 2025.
- The microchip must have been implanted before the rabies vaccination. The form must confirm this sequence.
- The form can only be issued a minimum of 28 days after the first rabies vaccination.
- CDC Dog Import Form (online, completed by owner).
- ACF reservation required; if documentation is valid, no quarantine — inspection + vaccine update only, then released.
- 🚨 After 31 July 2025, USDA export health certificates are no longer accepted for this purpose. Only the Certification of U.S.-Issued Rabies Vaccination form is accepted.
🟡 Scenario B — Foreign-Vaccinated Dog + Valid Titer Test (High-Risk Country)
Your dog was vaccinated abroad, you have a valid titer test, and you want to enter without quarantine.
- Certification of Foreign Rabies Vaccination and Microchip form — must be completed by the examining foreign vet and endorsed by an official government veterinarian. Must be issued no more than 30 days before travel; valid for single entry only.
- CDC-approved laboratory rabies titer test: blood sample must be drawn at least 30 days after the first valid rabies vaccination and at least 28 days before US entry. Once passed, the titer remains valid as long as the vaccination schedule is maintained — no repeat testing needed.
- ACF reservation at one of the 6 airports: examination + vaccine update, no quarantine if titer is valid.
- CDC Dog Import Form (online).
- The ACF airport must be the dog's first US port of entry.
🔴 Scenario C — Foreign-Vaccinated Dog, No Valid Titer Test (High-Risk Country)
Your dog was vaccinated abroad, you have no titer test or it is not current.
- All Scenario B documentation still required (Certification of Foreign Rabies Vaccination + CDC Dog Import Form).
- ACF reservation: examination + vaccine update AND mandatory 28-day quarantine. All costs are the owner's responsibility.
- The dog remains at the ACF facility for the full 28 days; early release is not possible.
- This is the most expensive and time-consuming scenario — quarantine costs typically USD 50–200 per day depending on facility and city.
- 💡 Recommendation: A titer test arranged 60–90 days before travel eliminates Scenario C entirely.
🟢 Scenario D — Low-Risk Country (e.g. EU, UK, Canada, Australia, Japan)
Your dog has only been in low-risk countries in the past 6 months.
- CDC Dog Import Form (online) — valid for 6 months, multiple entries.
- ISO-compliant microchip.
- Dog must appear healthy.
- No ACF airport restriction — you can arrive at any US airport.
- No rabies vaccination certificate required by the CDC for entry from low-risk countries (though your airline or destination state may have additional requirements).
- No quarantine.
- Note: if the dog visited a high-risk country at any point in the past 6 months — even as a transit stop where the dog left the plane — the high-risk pathway applies.
📄 CDC Dog Import Form: What It Is, How to Complete It
Completed Online by the Owner
The form is completed at cdc.gov by the owner or shipper — not the vet. One form per dog. The vet does not sign this form.
Receipt Sent by Email
After email verification, a receipt is sent. Present it as a printout or on your phone screen to customs and to your airline at check-in.
Validity: 6 Months (Low Risk) / Single Entry (High Risk)
For high-risk countries: the form is valid for single entry only and only on the arrival date specified in the form. If the date changes, a new form is required.
Must Be Shown to the Airline First
If travelling by air, you must present the CDC receipt at the airline desk before boarding. Airlines may refuse to accept the dog without the receipt.
Arrival Airport Must Match
For high-risk countries, the arrival airport stated in the form must exactly match your actual arrival airport. Any discrepancy results in the dog being refused entry.
When to Complete It
For high-risk countries: complete it 2–10 days before travel. It can be completed earlier, but the date information must be accurate. For low-risk countries: complete it any time before departure.
📋 The Two Certification Forms: Who Fills Them Out and When
| Form | Who Completes It | Endorsement | Validity | Who Needs It |
|---|---|---|---|---|
| CDC Dog Import Form | Owner / shipper (online) | No endorsement needed | High risk: single entry, specified date only; Low risk: 6 months | ALL dogs |
| Certification of U.S.-Issued Rabies Vaccination | USDA-accredited vet (VEHCS system) | USDA digital endorsement required | Until rabies vaccination expires (1 or 3 years) | US-vaccinated dogs returning from high-risk countries |
| Certification of Foreign Rabies Vaccination and Microchip | Examining foreign vet | Official government vet endorsement required | 30 days from issue; single entry only | Foreign-vaccinated dogs from high-risk countries |
🚨 Microchip Sequence Is Critical: The rabies vaccination must always have been given after the microchip was implanted. If the sequence is reversed, the vaccination is considered invalid — all documents become void. The microchip number must match exactly on all Certification forms and the CDC Dog Import Form.
🩸 Rabies Titer Test: How to Avoid Quarantine
Sequence is mandatory: microchip before vaccination. For a first rabies vaccination, the dog must be at least 12 weeks (84 days) old.
⏱ Foundation requirementThe blood sample for the titer test must be drawn at least 30 days after the first valid rabies vaccination. For dogs with more than one valid vaccination on record and a continuous vaccination history, this waiting period does not apply — blood can be drawn immediately after a booster.
⏱ At least 30 days after vaccinationBlood must be sent to a CDC-approved laboratory. Results from non-approved labs are not accepted under any circumstances. The list of approved laboratories is available at cdc.gov. Kansas State University Rabies Laboratory is one of the most commonly used by international travellers.
⏱ Approved lab onlyThe titer test result must have been received at least 28 days before the date of US entry. A passing result is valid indefinitely as long as the vaccination schedule is maintained without interruption. If the vaccination lapses, the titer is voided and a new test is required.
⏱ At least 28 days before entryThe titer report must travel with the dog and be presented at the ACF alongside the Certification of Foreign Rabies Vaccination form. Without a valid titer, a 28-day quarantine at the ACF is unavoidable — at the owner's expense.
⏱ Carry with you✈️ The 6 Approved ACF Airports and Reservations
Dogs arriving from high-risk countries must enter through one of the following 6 CDC-approved Animal Care Facility airports. No other US airport can accept them:
| Airport | City | ACF Facility | Important Note |
|---|---|---|---|
| JFK | New York, NY | The ARK at JFK | Not Newark (EWR) or LaGuardia (LGA) — must be JFK specifically |
| LAX | Los Angeles, CA | Kennel Club LAX / Rue's Kennels | Cargo arrival recommended where possible; delays possible for cabin/baggage arrivals |
| ATL | Atlanta, GA | Dandie Scottie Kennel | — |
| MIA | Miami, FL | Pet Limo | — |
| IAD | Washington D.C. | Pender Pet Retreat | All dogs still require AWB number; formal entry processing takes place here |
| PHL | Philadelphia, PA | Gateway Animal Care Center | — |
⚠️ Book Your ACF Reservation at Least 21 Days in Advance
ACF facilities operate at capacity. The ARK at JFK explicitly states that email inquiries do not constitute a reservation. Contact the ACF at your chosen airport before purchasing your flight ticket and get written confirmation of your booking. Your ACF reservation confirmation must be declared in your CDC Dog Import Form. If you have no titer test, a separate quarantine reservation will be needed. Build the ACF reservation into your planning before you book flights.

❓ Frequently Asked Questions
❓ I'm a US citizen returning with my dog from a high-risk country. Do the same rules apply?
Answer: Yes. CDC rules are applied based on where the dog has been in the past 6 months — not the owner's nationality. If your dog was present in a high-risk country, the high-risk pathway applies regardless of citizenship. The advantage for US-vaccinated dogs is that you can use the Certification of U.S.-Issued Rabies Vaccination form, which typically allows ACF processing without quarantine — provided it was completed before departure.
❓ My dog is coming from a low-risk country (e.g. Germany, UK, France). Do I still need the CDC form?
Answer: Yes — the CDC Dog Import Form is required for all dogs entering the US regardless of origin. However, the form for low-risk countries is much simpler, valid for 6 months, and there is no ACF airport restriction or quarantine requirement. No rabies vaccination certificate is required by the CDC for low-risk country entries (though airlines and specific US states may have their own requirements).
❓ My dog transited through a high-risk country but never left the airport. Does the high-risk pathway apply?
Answer: CDC considers the dog's physical presence in the country — not just passport stamps. If the dog remained on the aircraft or in the international transit zone and did not clear customs in the high-risk country, it is generally not considered to have been "in" that country. However, this is a grey area. Contact the CDC directly (800-232-4636) before travelling to confirm your specific situation.
❓ What happens if my dog is refused entry?
Answer: A dog refused due to missing documents, an invalid form, an unapproved airport, or a health issue will be returned to the last country of departure at the owner's expense. All return costs — cargo, temporary quarantine, vet fees — fall on the owner. This is why preparing documents well in advance and confirming directly with the ACF is so important.
❓ Do cats follow the same CDC rules?
Answer: No. CDC dog import rules apply to dogs only. There is no federal rabies vaccination requirement for cats entering the US. However, airlines and some US states may have additional requirements. Check with your airline and your destination state before travelling with a cat.
❓ Which CDC-approved lab should I use for the titer test?
Answer: Kansas State University Veterinary Diagnostic Laboratory (Manhattan, KS) is the most widely used for international travellers. The Auburn University College of Veterinary Medicine is also approved. The full current list is available at cdc.gov. Blood must be drawn by a licensed vet, properly stored, and shipped per the lab's instructions to ensure valid results.

DOWNLOAD PATIFY FREE🎯 The Bottom Line: Start 60–90 Days Out
"Reading the CDC rules a few days before your flight is the most expensive mistake you can make."
Entering the US with a dog from a high-risk country is entirely achievable with the right preparation — but the process involves a 30-day blood draw window, a 28-day titer validity margin, government vet endorsements, and ACF reservations. When you add all of these up, 60 days minimum — ideally 90 — is the planning horizon. The sequence is the foundation: microchip first, vaccination second, titer test third. Everything else follows from that.
Right paperwork, smooth entry. 🐕✈️
