Bringing Your Pet to the United States: A Complete Import Guide
I've moved internationally three times with Cooper, my 28kg Golden Retriever, and I can tell you with confidence: importing a pet to the United States is absolutely doable when you follow the right steps in the right order. The US welcomes both dogs and cats, but the process requires careful planning, proper documentation, and strict adherence to timelines. This guide walks you through everything you need to know.
What Pets Are Allowed Into the US?
Good news: both dogs and cats are allowed to enter the United States. There are no breed restrictions for either species, so your pet's breed won't disqualify them from entry. However, the requirements differ slightly between dogs and cats, and timing is critical.
Key Requirements at a Glance
For Dogs
- Microchip required: ISO 11784/11785 standard
- Rabies vaccination required: Must be current and administered after microchipping
- Health certificate required: Issued by an accredited veterinarian and endorsed by USDA APHIS
- CDC Dog Import Form: Required for all dogs entering the US since August 2024
- Minimum age: 6 months old
- No import permit needed
- No quarantine required if all documentation is complete and valid
For Cats
- Microchip not required (but recommended as best practice)
- Rabies vaccination not required (but recommended)
- Health certificate required: Issued by an accredited veterinarian and endorsed by government authority
- No import permit needed
- No quarantine required if documentation is complete
Note: While cats don't legally require rabies vaccination or microchipping for US entry, I strongly recommend both. They're standard practice internationally and provide essential protection and identification.
Your Preparation Timeline
6 Months Before Departure
Schedule a pre-travel vet consultation. Your veterinarian needs to assess your pet's health, discuss any travel concerns, and plan the vaccination and microchipping timeline. This is especially important if your pet has health conditions or anxiety. I scheduled Cooper's initial consultation 6 months out, which gave us time to address a minor ear issue before travel.
5-6 Months Before Departure
Have your dog microchipped (if not already done). Dogs must have an ISO 11784/11785 microchip. The microchip must be implanted before the rabies vaccination. Schedule this appointment and keep the microchip documentation safe—you'll need the chip number for your health certificate and CDC form.
5 Months Before Departure
Administer the primary rabies vaccination (for dogs). Your dog must be at least 12 weeks old. After this vaccination, you must wait 21 days minimum before your pet can travel. The rabies vaccine must be current and not older than 12 months at the time of travel. Mark this date on your calendar—it's a hard deadline.
4 Months Before Departure
Book your international pet transport or airline. If you're flying with your pet, contact airlines early. If using a pet transport service, get quotes and confirm availability. I used a cargo service for Cooper's move to Europe, and booking 4 months ahead gave me peace of mind and better rates.
2 Months Before Departure
Schedule your health certificate appointment. The health certificate is valid for only 10 days, so timing is crucial. Book your vet appointment for 10-12 days before your departure date. The certificate must be issued by an accredited veterinarian and then endorsed by USDA APHIS—this endorsement is a separate step that takes additional time.
For dogs: Complete the CDC Dog Import Form. Access it at the CDC's dog import page. This form has been required for all dogs entering the US since August 2024. You'll need your dog's microchip number and vaccination details. If your dog is from a high-risk rabies country, you'll need additional certification of US-issued rabies vaccination.
1 Month Before Departure
Confirm all documentation with your vet. Ensure your vet understands the US requirements and has access to the USDA VEHCS system for health certificate endorsement. Verify that your pet's microchip is registered and the chip number is correct. Double-check rabies vaccination dates and ensure the vaccine is still valid.
Arrange USDA APHIS endorsement. Your vet will submit the health certificate to USDA APHIS through the VEHCS system for endorsement. This process can take several days, so don't wait until the last minute.
2 Weeks Before Departure
Finalize travel arrangements. Confirm your flight or transport booking, arrange ground transportation, and prepare your pet's travel crate or carrier if flying. Update your pet's ID tags with your new US address and phone number.
10-12 Days Before Departure
Schedule your health certificate appointment. This is your final vet visit before travel. The certificate is valid for only 10 days, so timing is critical. Your vet will examine your pet, confirm they're healthy to travel, and issue the health certificate. The certificate must be signed and dated by the vet.
7-10 Days Before Departure
Obtain USDA APHIS endorsement of your health certificate. Your vet submits the certificate through VEHCS. Once endorsed, you'll receive the original certificate. Keep this document safe—you'll need it at entry.
3-5 Days Before Departure
Gather all documents and review your checklist. Collect your health certificate (original, endorsed), CDC Dog Import Form (for dogs), microchip documentation, vaccination records, and any airline-specific forms. Make copies of everything and store them separately from originals.
Prepare your pet for travel. Take your pet for a final walk, ensure they're calm, and pack their travel essentials: food, water, bowls, medications, comfort items, and waste bags.
Day of Departure
Arrive early and present all documents. At check-in or port of entry, have your health certificate, CDC form (dogs), and microchip documentation ready. US Customs and Border Protection may inspect your pet, so ensure they're calm and well-behaved.
Documents Checklist
- Original health certificate (issued by accredited vet, endorsed by USDA APHIS)
- CDC Dog Import Form (for dogs only)
- Microchip documentation with chip number (dogs required; cats recommended)
- Rabies vaccination certificate with date and vaccine details (dogs required; cats recommended)
- Proof of microchip registration
- Airline pet travel form (if flying)
- Pet passport or travel permit (if applicable from origin country)
- Copy of your pet's medical records
- Proof of identity (your passport)
- Proof of US residency or address
Critical Timing Rules You Cannot Ignore
For Dogs
- Microchip must come before rabies vaccination. This is non-negotiable.
- Rabies vaccination must be at least 21 days before travel. If your dog is vaccinated on day 1, they cannot travel until day 22.
- Rabies vaccine must not be older than 12 months at travel. If vaccinated more than 12 months ago, a booster is required.
- Health certificate is valid for only 10 days. Schedule your vet appointment 10-12 days before departure, not earlier.
- USDA APHIS endorsement takes 3-5 business days. Plan accordingly.
For Cats
- Health certificate is valid for only 10 days. Same timing as dogs.
- No quarantine is required if your cat arrives with complete documentation.
Special Considerations
Service Animals
If your dog is a trained service animal, they're protected under the DOT ACAA and can fly in the cabin with you at no extra charge, regardless of size. You'll still need the CDC Dog Import Form and rabies vaccination. Provide 48 hours advance notice to your airline and submit DOT Form 382.
Important note: Emotional Support Animals (ESAs) are not recognized by US airlines since January 2021 and must travel as regular pets in cargo or with a pet carrier fee.
Military Personnel
Military members relocating with pets should verify current regulations with their branch, as some military moves have modified procedures.
Common Mistakes to Avoid
- Scheduling the health certificate too early. It's valid for only 10 days—don't get it 3 weeks before departure.
- Forgetting the CDC Dog Import Form. Required for all dogs since August 2024. Missing this will delay or prevent entry.
- Not microchipping before rabies vaccination. The microchip must come first for dogs.
- Using an expired rabies vaccine. Vaccines older than 12 months require a booster.
- Skipping USDA APHIS endorsement. The health certificate must be endorsed—a vet signature alone isn't enough.
- Not registering the microchip. A microchip is useless if it's not registered with your contact information.
- Traveling with copies instead of originals. Bring original documents to the port of entry.
- Underestimating travel stress. Acclimate your pet to their carrier weeks in advance.
Costs to Budget For
Expect to spend $300–$800 on the import process itself (vet visits, microchip, health certificate, CDC form). If using a pet transport service, costs range from $1,500–$5,000+ depending on distance and service level. Airline pet fees (if flying with your pet) typically run $100–$300 per flight. I budgeted $2,000 for Cooper's move to Europe and came in close to that estimate.
After Arrival in the US
Once your pet arrives, schedule a post-travel vet check within 1-2 weeks. Your pet may experience stress-related digestive issues or behavioral changes. Keep all original documents for your records—you'll need them if you travel internationally again or if questions arise about your pet's health history.
