Bringing a dog from Mexico to the US involves navigating specific requirements to ensure a smooth and safe journey. This guide will provide you with all the information you need, from vaccinations to paperwork, making the process as stress-free as possible. Let’s explore the essential steps and regulations to ensure your canine companion can join you in the United States, ensuring a safe and pleasant relocation for both of you.
1. Understanding the CDC’s Dog Import Regulations
Bringing your dog from Mexico to the United States requires understanding and adhering to the regulations set by the Centers for Disease Control and Prevention (CDC). These regulations are in place to protect public health and prevent the introduction of diseases, such as rabies, into the U.S. Knowing the specific requirements ensures a smooth and compliant entry for your pet.
1.1 What are the Main CDC Requirements for Importing Dogs?
The CDC has specific requirements for dogs entering the United States, which include:
- Age Requirement: Dogs must be at least 6 months old to enter the U.S.
- Microchipping: All dogs must be microchipped for identification purposes.
- Health Appearance: Dogs must appear healthy upon arrival.
- CDC Dog Import Form: A completed CDC Dog Import Form must be submitted online.
1.2 Why are These Regulations Important?
These regulations are critical for preventing the reintroduction of dog rabies into the United States, which was eliminated in 2007. According to the CDC, dog rabies is not controlled in over 100 countries, making imported dogs a potential risk. Adhering to these requirements protects both people and pets.
1.3 Where Can I Find the Most Up-To-Date Information?
For the most current and detailed information, always refer to the official CDC website. Regulations can change, so it’s essential to stay updated before planning your dog’s travel.
2. Microchipping Your Dog
Microchipping is a crucial step in preparing your dog for entry into the United States. It serves as a permanent form of identification, helping to reunite you with your pet if they get lost. The CDC mandates microchipping as part of its import requirements.
2.1 Why is Microchipping Required?
Microchipping ensures that your dog can be easily identified and traced back to you. This is especially important if your dog gets lost or separated from you during travel. The microchip contains a unique identification number that can be read by veterinarians and animal shelters.
2.2 What Type of Microchip is Acceptable?
The CDC does not specify a particular type of microchip, but it is recommended to use an ISO-compliant microchip (15 digits). This ensures that the microchip can be read by scanners in the United States.
2.3 How Do I Register My Dog’s Microchip?
After your dog is microchipped, it is essential to register the microchip number with a registry service. This registry should include your contact information, so you can be contacted if your dog is found. Common microchip registry services include Found Animals Registry and PetLink.
3. Rabies Vaccination and Documentation
Rabies vaccination is a critical aspect of bringing your dog from Mexico to the United States, particularly if your dog is coming from or has been in a high-risk country. Proof of rabies vaccination may be required based on where the dog has been in the last six months and whether the dog was vaccinated in the United States or elsewhere.
3.1 Is Rabies Vaccination Always Required?
While not always mandatory, rabies vaccination is highly recommended and may be required depending on your dog’s travel history. Dogs arriving from countries with a high risk of dog rabies must be protected against rabies.
3.2 What Documentation Do I Need for Rabies Vaccination?
You will need an official rabies vaccination certificate from a licensed veterinarian. This certificate should include:
- Your dog’s name, breed, age, sex, and color
- The microchip number
- The date of vaccination
- The type of vaccine used
- The date the vaccination expires
- The veterinarian’s signature and license information
3.3 What if My Dog is Not Vaccinated Against Rabies?
If your dog is not vaccinated against rabies and is coming from a high-risk country, they may be subject to quarantine upon arrival in the United States. Quarantine periods can vary, and you will be responsible for the costs associated with quarantine.
4. Completing the CDC Dog Import Form
The CDC Dog Import Form is a mandatory requirement for all dogs entering the United States. This form collects information about your dog, its health history, and your contact information. Completing this form accurately and submitting it online is essential for a smooth entry process.

The CDC Dog Import Form is available on the CDC website. Make sure to access the official CDC website to ensure you are using the correct form.

5. Traveling from a High-Risk Country
If your dog is traveling from or has recently been in a country considered high-risk for rabies, there are additional requirements to be aware of. These measures are in place to prevent the spread of rabies and protect public health.
5.1 Which Countries are Considered High-Risk for Rabies?
The CDC maintains a list of countries considered high-risk for dog rabies. This list can change, so it’s important to check the CDC website for the most current information.

Dogs arriving from high-risk countries may be subject to:

- Rabies Antibody Titre Test: This blood test measures the level of rabies antibodies in your dog’s blood. It must be performed by an approved laboratory.
- Quarantine: Your dog may be subject to quarantine upon arrival in the United States, even with proof of vaccination and a rabies antibody titre test.
5.3 What is a Rabies Antibody Titre Test?
A rabies antibody titre test, also known as a FAVN (Fluorescent Antibody Virus Neutralization) test, measures the level of rabies antibodies in your dog’s blood. This test helps determine if your dog has a sufficient immune response to the rabies vaccine. The test must be performed by an approved laboratory, and the results must be submitted to the CDC.
6. Port of Entry Requirements
When you arrive in the United States with your dog, you will need to go through a designated port of entry. Different ports of entry may have specific requirements, so it’s important to be prepared.
6.1 Which Ports of Entry Accept Dogs?
Not all ports of entry accept dogs. Check with the CDC and the specific port of entry to ensure that they are equipped to handle animal imports. Major airports and land border crossings typically accept dogs, but it’s always best to confirm in advance.

If everything is in order, your dog will be allowed to enter the United States. If there are any issues or discrepancies, your dog may be subject to further inspection or quarantine.
