Because yes, crossing the pond with your dog can be an unforgettable experience... if you organize it well!

Is it possible to travel with a dog to the United States?

Yes, it is possible to travel with your dog to the United States, but it's not as simple as buying a ticket and packing your bags. The US authorities have very strict regulations regarding the entry of animals, especially to protect public health and prevent the transmission of diseases such as rabies. This means that you will need to comply with several health requirements, have the appropriate documentation, and follow certain steps before, during, and after the trip.In addition, if you have any questions, it is advisable to consult the official website of the Centers for Disease Control and Prevention (CDC) or the relevant consulate/embassy, as requirements may vary or be updated.

Let's take a look at what you need to know before taking the plunge with your furry friend:

General regulations for bringing pets into the country

The United States allows dogs to enter as companion animals, but requires that they meet certain health and documentation requirements. Requirements may vary slightly depending on the state you are traveling to, but all are regulated at the federal level by the Centers for Disease Control and Prevention (CDC) and the U.S. Department of Agriculture (USDA). It is essential to always check official sources before planning your trip.Since 2026, the United States has tightened controls on dogs coming from countries at risk of rabies (Spain is considered a low-risk country, but even so, vaccination and specific documentation are required).

Can you travel with dogs in the cabin?

Yes, some airlines allow your dog to travel with you in the cabin if it meets certain conditions: it must be small, fit in an approved carrier, and not exceed the maximum weight limit (usually around 18-22 lbs including the carrier). Otherwise, it must travel in the hold as special luggage. It is very important to book this service in advance, as the number of pets allowed per flight is limited.

Which breeds have restrictions?

Some airlines or transport companies may restrict travel to brachycephalic breeds (such as bulldogs, pugs, boxers, or shih tzus) due to the risk posed by changes in pressure and temperature during flight. In addition, certain states or counties in the US may have laws on potentially dangerous breeds, such as pit bulls.

Although the US does not generally prohibit any breeds at the federal level, it is always a good idea to check the regulations of your destination state or city and consult directly with the airline before booking.

 

Required documentation for traveling with your dog to the US

If you want to travel with your dog to the United States, it is not enough to have it vaccinated and ready. You will need to prepare in advance the specific documentation that the US authorities require upon entry. These requirements vary slightly depending on the dog's country of origin (Spain is considered a low rabies risk country, which makes things easier), but there are certain documents that are essential in almost all cases.

Below, we explain the main documents you will need. However, we recommend that before traveling, you always check the official CDC website and, if you have any questions, contact the US embassy or consulate in Spain directly, as requirements may change or vary depending on the specific case.

European passport for pets

Although the European passport is not valid as the sole document for entering the US, it is useful for proving the animal's vaccination history, microchip data, and health status. It is a recognized document within the EU and serves as backup for other evidence, but it does not replace the certificates required by the CDC or USDA. We recommend that you carry it with you along with the rest of your documentation.

International Veterinary Certificate (CVI)

The International Veterinary Certificate (also called 'Animal Health Certificate') is mandatory for many entry procedures into countries outside the EU, and the United States is no exception.

In general:

· It must be issued by an official veterinarian authorized in Spain (your regular veterinarian is not sufficient).

· In Spain, it is processed through the Ministry of Agriculture and is normally issued in English and Spanish.

· It is usually valid for 10 days from the date of issue (check dates according to your flight).

· It must clearly indicate the microchip number, the vaccinations administered (including rabies), and the animal's state of health.

You can find detailed information on the MAPA website: https://servicio.mapama.gob.es or go directly to your regional agricultural office or veterinarian authorized for exports.

Rabies vaccination test (valid and with microchip) This is the most important document. Since July 2026, the CDC requires that all dogs from countries such as Spain have:

· A microchip implanted before vaccination.

· A valid rabies vaccination, administered by a licensed veterinarian.

· A complete rabies vaccination certificate in English, signed by the veterinarian and including vaccine details (brand name, batch number, date of administration, expiration date, etc.).

Please note:
If your dog has never been vaccinated against rabies, or has been vaccinated recently, you may not be able to travel immediately. Some dogs must wait 28 days after vaccination before entering the US.

In addition, in some cases (for example, if you have lived in a high-risk country in the last 6 months), a neutralizing antibody test (rabies titer), issued by an approved laboratory, may also be required.

Health requirements and customs checks

In addition to having the proper documentation, your dog must meet certain health requirements in order to enter the United States without any problems. Border authorities, especially inspectors from the Centers for Disease Control and Prevention (CDC) and the USDA, may check your pet upon arrival and request proof of its health status.

Let's take a look at the main health requirements you should consider before traveling:

Rabies vaccination: CDC requirements

The United States does not allow dogs without rabies protection to enter, with few exceptions. As of July 2026, the CDC requires:

· That the dog is vaccinated by an authorized veterinarian with an internationally recognized vaccine.

· That the microchip has been implanted before vaccination.

· The dog must be at least 6 months old when entering the country.

· A complete rabies vaccination certificate in English must be provided, with all the necessary information.

In some cases, a serological test (antibody titer) may be requested to verify that the animal is truly protected.

Important:
The vaccination certificate must not have expired at the time of travel. If the vaccine is about to expire, we recommend that you have your pet vaccinated again before traveling (always at least 28 days before the flight).

Identification chip

The microchip is mandatory and must meet the following conditions:

· It must be compatible with the ISO 11784/11785 international scanner.

· It must be implanted before the rabies vaccine is administered.

· Its number must be correctly stated on all documents (passport, veterinary certificate, proof of vaccination, etc.).

If the microchip is not readable on arrival or does not match the documentation, the animal may be denied entry or sent to quarantine.

Pre-travel veterinary examination

In most cases, you will need to present a certificate confirming that the animal has been examined by a veterinarian in the days prior to travel and that it is clinically healthy to fly and enter the United States.

This examination is usually part of the process of obtaining the International Veterinary Certificate (IVC), but it is important not to leave it until the last minute, as:

· Some veterinarians must be officially authorized to issue it.

· The document may have a limited validity (usually 10 days).

· You will need to bring a printed copy and, in some cases, have it translated into English.

Possible quarantines or additional checks

Although the United States does not impose a general quarantine on dogs arriving from low-risk countries (such as Spain), it reserves the right to do so in specific cases, for example:

· If the documents are incomplete or contain errors.· If the dog appears ill upon arrival. · If the dog comes from a high-risk country or has recently traveled to one.In such cases, your dog may be temporarily detained for observation, examination by an authorized veterinarian, or even denied entry and returned to the country of origin.

That is why it is essential to carry all the correct, up-to-date, and organized documentation.

 

Airlines and flights: how does your dog travel?

One of the most delicate parts of the trip is choosing how and with which airline you will fly with your dog. Not all airlines accept animals, and the conditions for doing so vary considerably from one airline to another. In addition, the United States has strict rules on the air transport of pets, and in some cases, you may need additional permission or advance booking.

Therefore, it is essential to be well informed, compare options, and confirm all details with the airline before purchasing your ticket.

Dogs in the cabin vs. in the hold

On international flights to the US, dogs can travel in two ways:

· In the cabin: only allowed if the dog is small and, together with its carrier, does not exceed the maximum weight allowed (usually between 7 and 10 kg). It must be placed under the front seat and inside an approved carrier. In the cargo hold: for medium or large dogs. They travel as special cargo (pet cargo) in a pressurized and air-conditioned area of the aircraft. In this case, the carrier must comply with IATA regulations and be of a suitable size for the dog to move around comfortably. Each option has advantages and disadvantages. If your dog is small, traveling in the cabin may be more comfortable. If it is larger, traveling in the cargo hold will be the only option, so it is important to get it used to the carrier beforehand.Transportation requirements and maximum weight The IATA (International Air Transport Association) establishes general rules that almost all airlines follow:· The carrier must be sturdy, with ventilation on three sides, a waterproof base, and a secure closure.

· Your dog must be able to stand up, turn around, and lie down comfortably inside.

· In the cabin, the carrier must fit under the seat and be flexible or semi-rigid, depending on the airline.

· In the hold, it must include fixed water and food bowls, with water available.· Some airlines also require tags with the dog's details, the destination address, and the microchip number.

Always check the exact requirements on your airline's website, as there may be variations.

Approximate costs and tips for booking your flight

The price for taking your dog on the plane varies greatly depending on the airline, the type of flight, and whether it is traveling in the cabin or the hold. As a guide:

· In the cabin: between €50 and €150 per journey.

· In the hold: between €150 and €300 per journey, although on intercontinental flights it may be more.

Useful tips:

· Book in advance: many airlines only allow 2-3 animals per flight.

· Always confirm in writing that your dog has been accepted (some airlines explicitly request this).

· If your dog is brachycephalic (bulldog, pug, etc.), check whether the airline allows it to travel in the hold, as many airlines prohibit this.

· Choose direct flights to reduce stress on the animal.

 

Tips before, during, and after your trip

Traveling to the United States with your dog requires planning, patience, and a good dose of organization. Here is a list of practical recommendations that will help you prepare for the trip responsibly and reduce stress for both you and your furry friend.

Visit the vet before flying

Make an appointment with your vet several weeks in advance to:

· Check that your dog is in good health.· Verify that the microchip is correctly implanted and registered. · Verify that the rabies vaccination is valid and, if necessary, revaccinate.

· Request the International Veterinary Certificate (CVI) and any other official documents you may need.

· Ask if it is advisable to administer any antiparasitic or anxiolytic treatment (although many veterinarians do not recommend sedating dogs for flying).

Get your dog used to the carrier

One of the biggest mistakes is introducing the carrier on the day of travel. To avoid stress:

· Leave it at home several weeks beforehand with a blanket or toy inside.

· Practice short trips or mock journeys.

· If the dog is traveling in the hold, make sure it feels safe inside the closed carrier.

The carrier should become their safe place, not a punishment.

What to pack in your dog's suitcase

In addition to your luggage, prepare a backpack or bag specifically for your dog with:

· Printed copies of all documentation (passport, CVI, vaccination certificate, etc.).

 ·Leash, harness, muzzle if required by the airport or destination.                                                                                    

· Snacks, poop bags, and wipes.

· Blanket or T-shirt with your scent (to calm them down)

· Portable water bowl and food for the first few hours after arrival. · Don't forget to check the rules for importing pet food into the US: in general, wet food and unsealed dry food are not allowed. Always check with the airline or customs authorities.

Adjusting to the new schedule and environment in the US

Once you arrive at your destination:

· Give your dog time to rest and adapt.

· Maintain as stable a routine as possible: walks, feeding times, quiet moments, etc.

· If you are traveling to hot or cold areas, keep an eye on the temperature and the ground (asphalt, snow, etc.).

· Make sure you locate a nearby veterinarian as soon as you arrive (as a precaution).

Keep in mind that the time change can alter sleep and meal schedules, so observe this and gradually adapt your routine.

 

Do I need anything different if I am traveling to the US for tourism, work, or residence?

Yes, although many requirements are common, there are important differences depending on the reason and length of your stay in the United States. Spending a few weeks on vacation is not the same as moving there for work or to study with your dog.

Let's see what you need to consider depending on your situation:

Short stays vs. permanent relocation

· If you are traveling for tourism (vacation, visiting family, etc.), and your stay is less than 30-90 days, the usual requirements are:

· You only need the usual health and entry documentation (CVI, rabies vaccination, microchip, etc.).

· You will not be asked for any extra paperwork unless you are traveling to certain states with specific regulations.

· If you are traveling to live in the US (for work, study, or residence), you may need:

· Additional certificates depending on the state you are moving to.

· Additional documentation to register your dog in the country.

· Comply with local regulations on vaccinations, municipal licenses, insurance, etc.

In both cases, it is essential to check the regulations of the destination state or city.

Recommendations if you plan to move with your pet

Moving with your dog involves more than just going through customs:

· Find out if your place of residence requires dog licenses.

· In some cases, you will need to register the animal with the city or county (for example, New York requires an annual license).

· Be sure to purchase liability insurance, if required.

· Find a trusted veterinarian when you arrive.

· If your dog belongs to a breed that is restricted in certain states (such as pit bulls, American Staffordshire terriers, or Rottweilers), find out all the information you need before you move.

If in doubt, contact the U.S. consulate, embassy, or animal health department of the state you are moving to.

Additional procedures depending on the destination state (California, New York, Florida, etc.)

Each state may have additional requirements, for example:

· California: requires a valid health certificate (issued within the previous 10 days) and proof of rabies vaccination. CDFA – Animal Health

· New York: requires a municipal license if you are going to reside for more than 30 days. Some apartments have restrictions based on breed or size. Some apartments have restrictions based on breed or size.

Key recommendation: Before traveling, check the local regulations on the website of the department of agriculture or health of the state you are visiting. If you cannot find the information, ask the U.S. consulate in Spain directly.
