1. Research Entry Requirements and Restrictions

Start by reviewing the federal import requirements from:

• The US Centres for Disease Control and Prevention (CDC)
• The United States Department of Agriculture (USDA)

These bodies outline standards for vaccinations, health certifications, and travel history.

• Illinois typically follows these federal rules, but check the Illinois Department of Agriculture for state-specific updates.
• Understanding these early can help you avoid unexpected quarantine, denied entry, or delays at customs.

2. Consult Your Vet

Your veterinarian will ensure your pet meets all health requirements:

• Make sure all vaccines, especially rabies, meet US standards—this is a non-negotiable for most entry cases.
• Request a full health check to catch any issues that could be problematic during the flight.
• Ask about flea and tick prevention, heartworm medication, and microchipping (which may be required).
• Plan for a health certificate within 10 days of departure, as required by most airlines.

3. Secure the Right Travel Crate

Choose a crate that complies with IATA standards:

• Your pet must be able to stand, turn, and lie down comfortably.
• Look for features like secure latches, proper ventilation, and a spill-proof water container.
• Gradually introduce your pet to the crate using bedding, treats, or toys to create a familiar and calm environment.
• If you’re unsure about crate requirements, PetAir UK can guide you in selecting and customising a crate for international travel.

4. Understand Airline Policies

Airlines flying into Chicago have their own pet-specific protocols:

• Check for cargo vs. cabin restrictions, breed limitations, and paperwork expectations.
• Both O’Hare International (ORD) and Midway Airport (MDW) are busy hubs—book early to secure a pet space.
• During extreme temperatures, airlines may suspend pet travel in the hold—especially in summer and winter.
• Choose direct flights and avoid peak periods to reduce travel stress and complications.

5. Sort Out the Paperwork

Accurate documentation is essential:

• Prepare your pet’s vaccination records, microchip certificate, and official health certificate.
• Rabies vaccination is MANDATORY for flights to Texas, Florida, and all US destinations on American Airlines.
• Even when not legally required, rabies vaccination is highly recommended.
• If your pet has travelled through a high-risk rabies country, a rabies titre test or CDC import permit may be required.
• Carry both paper and digital copies for all relevant checkpoints.

6. Plan Your Travel Timetable

Chicago’s climate can be extreme, so time your journey accordingly:

• Summers can be hot and humid; winters can be freezing and snowy.
• Opt for milder months or book early morning/late evening flights in hotter seasons.
• When connections are unavoidable, choose layovers at airports with known pet-friendly facilities.
• Allocate time at Chicago’s airports for customs checks and pet collection—especially if using cargo services.
• Consider traffic congestion when arranging ground transport from the airport.

7. Consider Using a Specialist Pet Shipper

A pet relocation expert like PetAir UK can ease your workload:

• They coordinate everything from paperwork and vet checks to flight bookings and crate preparation.
• They can recommend optimal flight paths with proven animal-handling records.
• If your pet has health sensitivities or you’re unfamiliar with the process, their help can avoid costly errors.
• Ask for a quote detailing all included services—such as customs clearance, vet services, or home delivery in Chicago.

8. Prepare for Arrival in Chicago

Upon arrival, your pet must pass inspection:

• Keep all documents handy for customs and border checks.
• Pets not flying in-cabin will be collected from the designated cargo terminal.
• In winter, bring blankets or insulated carriers to protect your pet from the cold.
• Confirm your ground transportation is pet-friendly.
• Once settled, book a local vet visit to establish care in Chicago.

9. Alleviating Pet Stress and Anxiety

Prepare your pet mentally and emotionally for the transition:

• Start crate training weeks in advance to build familiarity.
• Stick to consistent routines before and after the move.
• Ask your vet about calming products—pheromone sprays, natural supplements, or medication.
• Include a blanket or item with your scent in the crate for comfort.
• Allow your pet time to explore your new home gradually to prevent overstimulation.

10. Settling into Life in Chicago

Help your pet adjust to their new home in the Windy City:

• Chicago is very pet-friendly, with parks, cafés, and walking paths along Lake Michigan.
• Register your dog with the city and ensure vaccines are up to date.
• In winter, consider boots and jackets for longer outdoor walks.
• In summer, avoid hot pavement and stick to shady, cooler times of day.
• Introduce your pet slowly to your neighbourhood, especially if you’re in a high-rise or busy area.
• Stay on top of routine vet care and social activities to help them feel at home.
