Bringing Your Pet to Sao Tome and Principe: A Vet's Complete Guide

I've been traveling with Pixel, my 7kg Cavalier King Charles Spaniel, for years, and I've seen countless pet import applications rejected at my clinic—often just days before departure. The most common mistake I see is people starting their paperwork too late. Sao Tome and Principe has specific entry requirements, and getting them right takes planning. Here's what I tell my clients: start 4–6 months before you travel.

This guide covers everything you need to import a dog or cat into Sao Tome and Principe, based on verified government requirements and international standards.

Are Dogs and Cats Allowed?

Yes. Both dogs and cats are allowed to enter Sao Tome and Principe as personal pets, provided they meet all health and documentation requirements. There are no breed restrictions for cats. For dogs, there are currently no banned breeds on record, though you should always verify with the destination authority before booking your flight.

Your Preparation Timeline

4–6 Months Before Departure

Schedule a pre-travel vet consultation. Your vet needs to assess your pet's health, check vaccination records, and plan the microchip and vaccination timeline. This is also when you'll discuss any health concerns and confirm your pet is fit to travel.

4–5 Months Before Departure

Get your pet microchipped (if not already done). The microchip must be ISO 11784/11785 standard (15-digit). This must happen before your pet receives its rabies vaccination—this is a critical sequencing requirement. If your pet already has a non-ISO microchip, you'll need to provide your own compatible scanner at the destination.

4–5 Months Before Departure

Apply for an import permit. Sao Tome and Principe requires an import permit for both dogs and cats. Typical processing time is 30 days. Contact the government veterinary authority of Sao Tome and Principe as early as possible. We're still verifying the exact issuing authority and application process—check directly with the country's agriculture or veterinary ministry.

3–4 Months Before Departure

Administer the first rabies vaccination. Your pet must be at least 12 weeks (3 months) old at vaccination. After the primary rabies vaccine, there is a mandatory 21-day waiting period before your pet can travel. A booster rabies vaccination is also required. Your vet will advise on the booster schedule based on your pet's vaccination history.

2–3 Months Before Departure

Complete any additional health checks. Sao Tome and Principe does not require a rabies titer test (antibody test) for entry—this is only required by rabies-free countries like Australia, Japan, and New Zealand. However, your vet may recommend routine parasite screening and a general health check.

10–14 Days Before Departure

Schedule your health certificate exam. The official health certificate must be issued by a licensed veterinarian and is valid for only 10 days. Do not get this too early. Your vet will examine your pet, verify all vaccinations and microchip details, and issue the certificate. This certificate must then be endorsed by your country's government veterinary authority (e.g., USDA APHIS if you're in the United States, APHA if in the UK, CFIA if in Canada).

7–10 Days Before Departure

Get your health certificate government-endorsed. After your vet issues the certificate, submit it to your country's government veterinary authority for official endorsement. This is a separate step and can take 3–5 business days. Plan accordingly—do not wait until the last minute.

5–7 Days Before Departure

Confirm your airline's pet policy and notify them of your pet's arrival. Different airlines have different rules for pet travel. Contact your airline directly to confirm cabin vs. cargo requirements, carrier specifications, and any advance notice they require. Most airlines ask for 48 hours' notice.

1–2 Days Before Departure

Final document check and pet preparation. Gather all original documents (health certificate, vaccination records, microchip documentation, import permit). Ensure your pet's carrier is properly labeled with your contact information. Take a recent photo of your pet in case of loss during travel.

Required Documents Checklist

  • Import permit (obtained from Sao Tome and Principe's government veterinary authority)

  • Vaccination records (original or certified copies)
  • Airline pet travel documentation (if required by your carrier)
  • Photo identification of your pet
  • Proof of ownership (passport, travel documents, or registration)

Port of Entry

Common Mistakes to Avoid

  • Microchipping after rabies vaccination. The microchip must come first. I've seen this rejection happen repeatedly.
  • Getting the health certificate too early. It's only valid for 10 days. Schedule your vet exam for 7–10 days before departure, not earlier.
  • Forgetting government endorsement of the health certificate. The vet's signature alone is not enough. Your country's veterinary authority must endorse it separately.
  • Not applying for the import permit early enough. 30 days is standard, but delays happen. Apply 4–6 months ahead.
  • Assuming your pet doesn't need a booster rabies vaccine. Most pets do. Confirm with your vet based on vaccination history.
  • Traveling with a non-ISO microchip without a scanner. If your pet has an older microchip, bring your own compatible reader or have it replaced with an ISO chip.
  • Not confirming airline pet policies in advance. Carriers have different rules for cabin vs. cargo, carrier size, and advance notice. Call your airline directly.

Special Considerations

Service Dogs

Trained service dogs (guide dogs, hearing dogs, mobility dogs) are recognized for travel purposes by most ICAO signatory countries, including Sao Tome and Principe. However, service dog status does not waive import documentation requirements. Your service dog must still have a microchip, rabies vaccination, health certificate, and import permit. Airlines typically require 48 hours' advance notice for service dogs. Emotional support animals (ESAs) are not recognized for travel purposes and do not receive special exemptions.

Military Personnel

If you're relocating with the military, standard civilian import rules apply. Import permits are not waived for military personnel. Check with your transportation management office (TMO) for any streamlined processes, but plan for the full 4–6 month timeline.

What We're Still Verifying

The following details are not yet confirmed for Sao Tome and Principe—contact the country's government veterinary authority directly:
