Brazil is easy to enter: no import permit, no quarantine, and MAPA inspects your pet and paperwork on arrival. You need a rabies vaccination (for a first shot, at least 21 days before departure), a broad-spectrum internal-and-external parasite treatment within 15 days of the certificate, and a USDA-endorsed health certificate — valid a generous 60 days from issue.

As with much of the region, the harder leg is coming home: Brazil is on the CDC's high-rabies-risk list.

Minimum lead time: about 0.7 months (21 days). About three weeks from a standing start: a first rabies vaccination needs 21 days before departure. Brazil's certificate is valid a generous 60 days. The real planning is the return to the US.

The requirements, in order

Order matters — several steps are only valid if the earlier ones were done first. This is the same sequence the planner above turns into dated deadlines.

  1. Rabies vaccination (21 days before departure)
    A current rabies vaccination is required. For a first (primary) dose it must be given at least 21 days before departure to Brazil. Animals under 90 days old may be exempt if unvaccinated and not exposed to urban rabies in the last 90 days.
    Planning to bring a dog back to the US? Use a US-issued rabies vaccine given at least 28 days before you leave — that satisfies both trips.

  2. Internal & external parasite treatment
    A broad-spectrum treatment against both internal and external parasites (US-authorized products), given within 15 days before the health certificate is issued.

  3. Health certificate endorsed by USDA APHIS
    The international veterinary certificate (Certificado Zoosanitário), issued by a USDA-accredited vet after a clinical exam done within the prior 10 days, then endorsed by USDA APHIS. It is valid for 60 days from issue and must still be valid on arrival.

The return trip is the hard part (for dogs)

Because Brazil is CDC high-risk, bringing a dog back to the US takes setup before you go: the simplest route is a US-issued rabies vaccination given at least 28 days before you leave, documented on the CDC certification form, plus a CDC Dog Import Form on return, a microchip, and the dog 6+ months old. A microchip is optional for Brazil but required to bring a dog home — get one before the rabies shot. Cats have none of these return requirements.

The final-week cluster

Bundle the last steps: the parasite treatment (within 15 days of the certificate), the clinical exam (within 10 days), then the USDA-accredited vet issues the certificate and APHIS endorses it. Travel within its 60-day validity.

The trip home: bringing your dog back to the US

Brazil is a CDC high-risk country for dog rabies — set up the return BEFORE you leave. The step people miss: a Certification of U.S.-issued Rabies Vaccination must be completed by a USDA-accredited vet and endorsed by USDA before your dog departs the US (and the microchip must have been implanted before the rabies shot, or the vaccination is invalid for re-entry). Before flying back, also file the free CDC Dog Import Form — a single-entry receipt for your arrival date. Your dog must be at least 6 months old and appear healthy. Skip the pre-departure certification and a US-vaccinated dog can face a CDC-registered facility, revaccination, and quarantine on return.

Cats are exempt — they aren't subject to the CDC dog-import rules and need no rabies paperwork to re-enter (Hawaii and Guam set their own quarantine even from the mainland).

FAQ

How long does it take to bring a dog from the US to Brazil?
About three weeks if your dog needs a first rabies shot (21-day wait before departure), plus parasite treatment and the USDA-endorsed certificate. The certificate is then valid 60 days.
Do I need an import permit for Brazil?
No — no permit and no quarantine for an accompanied pet. Brazil's MAPA inspects your pet and documents on arrival.
What about bringing my dog back to the US?
Brazil is CDC high-risk, so plan ahead: a US-issued rabies vaccine given 28+ days before you leave, a microchip (before the shot), dog 6+ months old, and a CDC Dog Import Form on return.
Is it different for cats?
The outbound rules are the same, but cats skip the CDC return process entirely. Use the cat toggle in the planner.
