If you wish to bring a cat or dog into Argentina, it must have been vaccinated against rabies between 30 days and 12 months before arrival. An accredited vet from your home country must also complete the Certificado Veterinario de la Argentina (Argentine Veterinary Certificate) and include a copy of the rabies vaccine certificate.
In the instance that animal is being imported for commercial purposes, these certificates must also be presented to the Argentine Consulate in your country of residence for legalisation (personal pets do not require this approval).
Airlines must inform the Argentine airport authorities about the animal's arrival at least 24 hours in advance in order to guarantee the attendance of a vet when the animal arrives.
Other pets (birds, invertebrates, tropical fish, reptiles, amphibians, and mammels such as rodents and rabbits) do not need anti-rabies certificates, but must meet other requirements and must have a health certificate.
