Moving with pets requires more than just booking a carrier—your animal's health and safety depend on careful preparation and vetting of transport requirements. Before your pet takes a single mile, understanding what health checks, certificates, and documentation matter can save you from delays, fines, or worse. Here's what you need to know to move your pet safely and legally.
Health Certificate Essentials
A health certificate (also called a health exam certificate or CVI—Certificate of Veterinary Inspection) is non-negotiable for most pet relocations, especially interstate or international moves. Your veterinarian must issue this within 10–14 days of transport, confirming your pet is disease-free and fit to travel. For domestic moves, requirements vary by state; some don't mandate it, while others require one for any animal crossing state lines.
Check your destination state's agriculture or animal control department website for exact rules. Many pet transport companies won't accept animals without one, regardless of whether it's legally required, because it protects both the animal and the service provider.
Vaccination Records and Legal Requirements
Current vaccinations are the foundation of transport eligibility. Rabies vaccination is the most critical—most carriers and airlines require proof of a valid rabies shot administered 30 days before travel but not more than 3 years prior (1 year for some vaccines). Many states legally mandate rabies vaccination for relocation.
Beyond rabies, expect to verify:
- DHPP (dogs: distemper, hepatitis, parvo, parainfluenza)—usually needed within 1 year
- FVRCP (cats: feline viral rhinotracheitis, calicivirus, panleukopenia)—typically within 1 year
- Bordetella or kennel cough vaccine (dogs)—often required for group transport or boarding during transit
- Proof of flea and tick treatment—some carriers and destinations require documentation within 30 days of travel
Order copies of all records from your vet at least 3–4 weeks before your move.
Pre-Transport Health Screening
A full pre-transport vet check isn't legally required everywhere, but it's worth the $150–$300 investment for peace of mind. This exam identifies underlying conditions (heart issues, joint problems, anxiety) that affect whether your pet can handle transport stress, flight pressure changes, or temperature fluctuations.
Pets with pre-existing conditions—senior animals, brachycephalic breeds (bulldogs, Persian cats), or those with respiratory issues—need explicit clearance before air transport. Many airlines ban certain breeds entirely or require additional documentation (like a respiratory clearance letter) costing another $75–$150.
If your pet is on medication, confirm your vet will provide a supply for the journey, clearly labeled with your pet's name, dosage, and frequency.
International Relocation: Extra Documentation
Moving internationally? Expect significantly more paperwork and $500–$2,000+ in additional costs. Requirements vary wildly by destination country:
- Microchip registration (typically $25–$50 one-time)
- Import permits from your destination country
- Health certificates valid only 10 days in many countries
- Quarantine periods ranging from 0–30 days depending on the country
- Blood tests for rabies antibody titers ($200–$400)
- Treatment for parasites or tapeworms with documented proof
The EU, Australia, Japan, and UK have particularly strict protocols. Start paperwork 8–12 weeks before departure.
Choosing a Pet Transport Provider: Health-Related Red Flags
When comparing transport companies, ask directly about their health requirements and how they handle medical emergencies mid-journey:
- Do they require a health certificate signed by your vet within a specific timeframe?
- What's their policy on animals with existing medical conditions?
- Do they provide temperature-controlled vehicles and rest stops?
- Is there a veterinary contact or emergency protocol during transport?
A reputable company will ask you extensive health questions before accepting your pet. Red flags include providers who ask nothing about health status or say "most animals are fine without a certificate."
Platforms like Mercoly let you compare multiple pet transport providers side-by-side, review their health policies upfront, and find trusted services in your area without endless phone calls.
Frequently Asked Questions
Q: How far in advance should I book my pet's pre-transport vet appointment? Book 6–8 weeks before your move to ensure your vet has time to run necessary tests, issue documents, and provide a health certificate dated appropriately close to your travel date.
Q: Can my pet travel if they're on anxiety medication? Yes, but tell your vet and the transport provider immediately—they may recommend calming supplements, shorter travel days, or specific handling instructions to keep your pet safe during the move.
Q: Do I need a health certificate if I'm driving my own car across state lines? Legally, no (for most states), but it's still smart to have one in case of accidents, vet visits en route, or disputes with authorities about your pet's health status.
