A dog or cat crossing a land border is treated as an animal entering another country, with a procedure of its own that is separate from its owners’ passports. What is asked for depends on the species, the countries involved and the direction of travel, and it is set by each country’s official animal-health service. This guide explains how the subject is organised and what to ask. It does not replace the official answer.
Whose rules apply
In Argentina, Paraguay and Brazil, pet travel belongs to the national animal-health or veterinary authority, not to immigration. Two sets of rules meet at every crossing: those of the country the animal leaves and those of the country it enters. The way back is a new entry. A paper issued for the outward trip may not be enough for the return, or may expire in the meantime.
Visitors from other continents should also look ahead to the journey home. Your own country has rules for an animal coming back from South America, and they can be stricter than anything asked here.
What the requirements depend on
- Species. Dogs and cats have the most familiar procedure. Birds, rodents, reptiles and other animals follow different rules, and some species fall under wildlife-protection law as well.
- Age. A very young puppy or kitten can be a special case.
- Route. Every country you pass through counts. The road from Puerto Iguazú to Ciudad del Este runs through Brazil.
- Purpose. A companion animal travelling with its owner is not treated like an animal moved for sale or breeding.
What rules of this kind cover
Without going into each country’s detail, such rules deal with four things: how the animal is identified, who certifies that it is healthy, which vaccinations and treatments must be up to date, and how long before the trip each paper has to be issued. Sometimes a private vet’s certificate has to be endorsed by the official service. We do not print the list here because it changes and differs by country.
How to prepare
- Ask the animal-health service of the country you are leaving what it needs for the exit.
- Confirm with the authority of the destination country, or its consulate, what it needs for entry.
- Ask specifically about the return.
- See a vet with weeks to spare.
- Keep the originals to hand, not at the bottom of a suitcase.
The journey itself
Long-distance buses, many taxis and ride apps set their own conditions for animals and often do not take them. That leaves your own car or a private transfer. With us, pets travel with advance notice: when you book, tell us the species, the size and whether the animal travels in a carrier. You can ask for stops along the way. The region is hot and humid for much of the year, so bring water for the animal.
The pet’s paperwork is the owner’s responsibility. If a document is missing at the border, the driver cannot fix it. Whether the crossing is available, and on what conditions, is confirmed at booking. See transfers to Paraguay and to Brazil.
